“I’ve always wondered what the scientific perspective of alcohol consumption is. I have been doing some research but the actual effects of it on the body range from beneficial to cancerous.”

The clinical science on alcohol consumption is vast and diverse. It’s easy to find studies that demonstrate the benefits of alcohol, but it is equally common to find research showing its dangers. Sorting through the data is not trivial, and getting the right answer from news reports is virtually impossible.

Let’s start with the facts:

1. Alcohol is addictive

Alcohol addiction is one of the most well-understood and dangerous risks of drinking. A propensity for addiction can run in families, but can affect anyone who drinks in excess. None of the health benefits of alcohol can negate the destruction caused by addiction, and anyone who drinks should be careful to avoid this terrible condition.

2. Alcohol damages the liver

Alcohol metabolism occurs in the liver and can cause severe damage when consumed in large quantities. Liver damage can usually be reversed if alcohol consumption stops.

3. Alcohol is associated with breast cancer (sort of)

Drinking is weakly associated with an increased risk of breast cancer. This is likely because alcohol increases aromatase activity in the human body, which increases estrogen production. Estrogen imbalance is a known cause of breast cancer. However, the association between drinking and breast cancer is negated by sufficient folate intake. Folate or folic acid is a B vitamin found in leafy green vegetables, fruits and legumes (and fortified foods). In other words, a healthy diet protects against alcohol induced breast cancer risk.

4. Alcohol protects against mortality from heart disease

Drinking alcohol reduces your risk of dying from a heart attack by preventing blood clotting. This effect is not limited to red wine, all spirits elicit substantial protection. The association appears to be dose-dependent, meaning that the more you drink the more protection you get. HOWEVER, you start raising your risk for the above mentioned problems with every additional drink per day. For men the ideal dosage is 2 drinks per day, for women it is 1 drink per day.

5. Alcohol raises good HDL cholesterol

Moderate drinking also reduces your risk of getting heart disease in the first place by raising beneficial HDL cholesterol without raising LDL cholesterol. Low HDL is a serious problem in America, and alcohol could be a significant benefit for some people. Here are other ways to raise your HDL cholesterol.

6. Red wine may slow aging

Aging research has been revolutionized by the discovery of a compound in red wine called resveratrol. Resveratrol has been shown to slow aging substantially in several model organisms. Though the effect in humans is still unknown, red wine is associated with many benefits that seem to go above and beyond the benefits of alcohol in general.

7. Red wine may protect against Alzheimer’s disease

Several studies have shown that red wine is associated with a decreased risk for Alzheimer’s Dementia, a devastating neurodegenerative disease that affects 1 in 4 people over the age of 90. The mechanism of action is unclear, but the benefits may be linked to the effect of red wine on fatty acids in the blood (raising the good stuff), or by slowing the aging process itself.

8. Alcohol causes accidents and behavioral problems

Even relatively safe levels of drinking can be deadly when combined with poor decision making. If you do choose to drink alcohol, always be sure that you’re in a safe environment and can get help if you need it. Being safe sometimes, or even usually, is simply not good enough.

There are plenty of good reasons to avoid alcohol if you choose, and many of the benefits can be garnered by simply increasing the amount or intensity of your daily physical activity.

However, the evidence is pretty clear that moderate alcohol consumption (1-2 drinks per day) can improve health and may be an important component of a healthy lifestyle. This is even true for those who pick up the habit later in life.

And last but certainly not least, some of the best times of my life have been over a drink with friends. And I guarantee you most of us aren’t thinking about our heart health while enjoying a great bottle of wine. As long as you consider safety first, never forget that smiling is one of the healthiest things you will ever do.

Here’s a fun question: what’s your favorite drink??

The science of aging is among the most dynamic and provocative in modern biology. Over the past two decades we have seen a virtual explosion in research investigating the molecular and behavioral systems that control the aging process. But the more researchers uncover about the science of aging, the more questions emerge.

Dietary restriction has long been considered the most potent regulator of aging. Restricting food intake by any means induces a series of metabolic changes in organisms from yeast to primates that serve to extend life. Studies are currently underway to investigate the ability of dietary restriction to extend life in humans.

Several biological changes are known to occur upon the onset of dietary restriction including a decline in reproductive ability, increased stress resistance and a slowdown of some metabolic processes.

Insulin signaling was among the first molecular pathways to be identified in the regulation of aging, and offered a direct tie between diet and the aging process.  In 1998 UCSF scientist Cynthia Kenyon showed that removing an insulin receptor gene (daf-2) in worms could double their lifespan. Her lab later showed that removing another insulin signaling gene (daf-16) could extend life even longer. I spoke to Kenyon about the relationship between diet and aging for this article.

Blocking insulin signaling in these worms did not just prevent the worms from dying and allow them to age longer. Instead the aging process actually slows so that older worms continue to behave like young worms. Also, as these experiments were repeated in different animals, it was shown that lowering insulin signaling also helps protect animals from stress and diseases such as cancer and heart disease.

Insulin is released as a direct response to glucose in the blood. This means that any time you eat a meal with carbohydrates, you are increasing your insulin signaling and likely accelerating aging. But this does not mean that you will live forever if you stop eating carbohydrates.

Interestingly, protein metabolism also contributes to accelerated aging, but through a different mechanism. Even more intriguing is that restricting protein increases lifespan to a greater extent than restricting sugar.

So is it simply calories that promote aging?

Probably not. For one thing, the effect of a calorie from protein is greater than a calorie from carbohydrate, making it unlikely that a calorie is the basic unit of impact. Second, there is evidence that calories are not required to accelerate aging.

Recent studies have shown that the mere act of smelling food can reduce lifespan. The mechanism for this effect is still unknown, but seems to be tied to respiration.

According to Kenyon it is clear that “sensory perception influences lifespan,” at least in worms and flies.

Thus it is likely that aging is controlled by the interaction of several pathways, including metabolism, respiration and stress. Importantly, however, lifespan seems to be dependent on a handful of specific pathways rather than global changes in cellular function or breakdown. The idea that aging is an inevitable function of time must be put aside given the evidence that it is controlled at a genetic and environmental level.

This makes sense when you think about it. Different organisms exhibit vastly different lifespans and rates of aging that are too great to be explained by some kind of universal cellular breakdown. A more parsimonious hypothesis is that organisms differ in specific genetic factors that, combined with environmental influences, regulate lifespan.

So how should we mortal humans react to these findings?

The genes linking diet and aging are highly conserved through evolution, indicating that there is a great chance human aging is sensitive to diet. Indeed, insulin-related genes have been found to be important in long-lived human populations. This suggests that the pathways discovered in worms and other organisms have similar functions in humans.

What is not clear is how much influence diet has on lifespan and to what extent we are able to manipulate it. It is already known that abnormal insulin activity in humans is linked to higher disease rates, especially “diseases of civilization” such as heart disease, hypertension, type 2 diabetes and cancer. And these diseases are clearly associated with diets rich in processed foods, especially refined carbohydrates.

The effect of protein consumption on lifespan in humans has yet to be investigated. Envisioning an experiment that would test the influence of smelling food on human aging is difficult to even imagine.

Although direct evidence is not available, there is good reason to suspect that a diet with low glycemic load may extend human lifespan. In November 2009, Kenyon’s lab reported that adding glucose to a worm’s normal diet shortens lifespan, but has no effect on the long-lived worms that lack insulin signaling genes daf-2 and daf-16. This discovery prompted Kenyon herself to adopt a low-carbohydrate diet.

Despite this there is still not sufficient evidence to recommend a calorie restricted diet for humans to extend life, largely because optimal nutrition levels for a given individual are unknown. However, most people would benefit vastly by eliminating processed foods and refined carbohydrates from their diets as much as possible.

Focusing on fresh, whole foods, enjoying an occasional glass of wine, avoiding smoking and getting regular exercise can add 14 years to the life of an average person. Maintain a healthy weight as well and your outlook gets even better.

Would you change your diet to be healthier and live longer?

Garlic

People often say that garlic has medicinal properties. Some claim it lowers blood pressure, others swear it helps cholesterol and reduces clotting, and some even think it protects against cancer. I’ve also heard that garlic is “healthier” 10-15 minutes after it has been crushed or minced. Is any of this true?

The Science of Single Foods

As someone who regularly reads the scientific literature on the health benefits of food I can assure you that this is not an easy question to answer. The problem is that the effect of any single food on human health is likely to be small at best, and small effects are very difficult to detect with reliability. Studies must be incredibly well-designed to contribute anything of value to our understanding of how a food works in the human body. Also, many studies must be taken together in context for the data to be evaluated properly.

I have been researching this garlic question on and off for months and feel only slightly more confident today than I did when I started. To summarize, there are a good number of studies addressing the health value of garlic, but very very few of them are well-designed and published in reputable journals. The problem with having a large number of poor-quality studies is that results are often conflicting and difficult to interpret. Thus, when another scientist comes in to do a meta-analysis (pooling data from many studies and re-analyzing it for stronger statistics) the findings are usually inconclusive.

However, inconclusive findings do not enable me (or anyone) to say there is no benefit. What I can say is that more research is needed and if there is a benefit it is likely to be small. (How unsatisfying is that?!). But personally I would still recommend eating garlic for health. Why?

Small Benefits Are Important

Although we cannot say exactly why garlic is good for you, it is almost certainly not bad for you. Moreover, although it is difficult to attribute a particular health benefit to a single food, we do know that people who eat the most vegetables tend to be healthier than people who fewer.

Many nutrition scientists are beginning to suspect that the benefit of foods like garlic are primarily relevant in the context of a whole diet and cannot be evaluated independently. This means that it is less important that the individual studies I mentioned earlier are inconclusive, because they are likely not sensitive enough to evaluate the complex interactions of whole foods and food combinations on human physiology.

The Best Reason To Eat Garlic

The most important thing you can do for your health is eat a diverse diet of natural, unprocessed foods. Garlic is an amazing ingredient that imparts a unique and wonderful taste to the food it is cooked with. If you like garlic and it encourages you to eat your vegetables, then it’s good for you.

If it makes you feel slightly better knowing that it may help your heart or reduce inflammation, that’s awesome but less important.

What About The Crush?

If you do hope garlic can add to your health, is there any benefit in crushing it early? Probably.

Scientists have long suspected that the active ingredient in garlic is a substance called allicin. A recent study from Queen’s University showed that it is actually a decomposition product of allicin that has the most potent antioxidant activity.

Interestingly, allicin is created from an enzyme called alliinase that is not released from plant cells until they are damaged. Alliinase is what gives garlic (and onions) their strong odor and is thought to be a self-defense mechanism for these plants. When garlic is crushed, alliinase becomes active and begins creating allicin. As allicin is created and breaks down, the antioxidant potential of garlic is dramatically increased. Optimal antioxidant levels are created about 10 minutes after garlic is crushed.

It has not yet been shown that this increased antioxidant activity is a benefit to humans, but the principle is compelling enough to try to remember to crush your garlic a little early. If you are anything like me though, this feat is almost impossible. Apparently garlic hasn’t done that much for my memory.

What are your favorite reasons to eat garlic?

Mango Vendor in Bangkok

Several readers have asked lately about the impact of fruit–specifically the sugar in fruit–and it’s capacity to cause weight gain and accelerate aging through insulin signaling:

“Do people usually gain weight because of eating fruit and does the sugar in fruit age us?  I just hate to think that I am doing my body harm by eating fruit.”

If this question sounds insane to you, it shouldn’t. It is actually a very reasonable query that was sparked by two Summer Tomato articles, one about saving money while eating healthy and another on calorie restriction, aging and quality of life. In the first article I recommend thinking of fruit as dessert, a treat to be enjoyed once or twice per day. The second article is about the impact of sugar and calories on aging.

Body Weight

The fact is that fruit contains a lot more sugar than other natural foods and in large enough quantities it can contribute to weight gain. But fruit is certainly not bad for you, nor is it worse for your health than anything else in life.

The sugar in fruit contributes calories to your diet, but since you need calories to survive fruit is still a very good choice. The reason is that in addition to sugar (fructose, to be specific) fruit also has vitamins, minerals, antioxidants, fiber and many other things that contribute to health and possibly slow aging.

On the rare occasions when I do make an effort to lose a little weight, however, remembering that fruit should be dessert is something I keep in the back of my mind. I eat fruit every day, but when trying to lose weight I keep it under two servings and always choose whole fruit–avoiding anything blended or juiced. (Drinking calories is usually a bad idea.)

But this healthstyle tactic is not for everyone.

Why?

Unlike most people trying to lose weight, I already have a very healthy diet and fruit is one of the easiest places I can trim calories without feeling deprived. Cutting out things like fat and protein make dieting very difficult because you are always hungry. In my experience reducing unnecessary carbohydrates–especially sugars–is the easiest and healthiest way to lose weight.

But it is essential to remember most people are not overweight because they eat too much fruit and the vast majority of people would benefit from eating more of it.

Aging

The question about whether sugar causes aging is a fascinating one that I am very interested in.

Yes, in most organisms eating sugar has been shown to promote aging, but this has not been proven in humans. Sugar induces aging via the insulin signaling pathway, so therefore any food that increases insulin signaling could theoretically accelerate aging. The problem is that you need insulin to survive–those who cannot produce insulin have a disease called type 1 diabetes.

The good news is that eating a diet that minimizes insulin signaling is also the best way to lose weight and stay healthy, so if you are living a healthy lifestyle (one that includes fruit) you do not need to worry about anything else.

Although fruits have sugar, it is extremely unlikely that they accelerate aging. In fact, most evidence suggests that fruit slows aging because of its high levels of vitamins, minerals and antioxidants.

If anti-aging is your goal, fruit is your friend not your enemy.

For more on insulin signaling, check out my post at MizFit Online, When is a calorie not a calorie.

Conclusion

While fruits contain sugar, they do not pose a special threat to your health goals. Eat and enjoy fruits as a wonderful and delicious part of life.

How much fruit do you eat?

Originally published August 31, 2009.

Despite being female and thus held to tough and often unrealistic physical standards, hitting the end of my third decade doesn’t cause me anxiety about either my appearance or place in the world.

In my experience, age is not an amount of time but a state of mind. As a child I always wanted to be a grown up, so I acted like one. It freaked my parents out sometimes, but that’s just how I was. In my mind, I still feel pretty much the same in that regard. I love to work hard and I thrive in positions of responsibility. Since both these traits get more important with age, I have actually enjoyed stepping into the adult role I’ve always felt I belonged in.

But that’s only one part of me.

In many other ways I’m as juvenile as ever. If you spend much time with me on Twitter (@summertomato) you’ve probably noticed I have the sense of humor of a 12-year-old boy. I blame my dad for that one. I’m also still shocked every time I hear that friends my age are getting married and having children. In my brain we’re not nearly old enough for that yet! But in reality, it is my friends who are normal and I’m the outlier.

Oh, and did I mention I’m still in school? Up until a couple years ago I carried a backpack with me everywhere, for better or for worse.

All these things give me a sense of agelessness, so it is hard to think of this birthday as anything but another day to do things I love. But part of my peace of mind certainly comes from the fact that I’m in pretty good shape physically–probably the best of my life. And at 30 this is definitely something to be proud of.

Summer Tomato readers know I attribute my good health almost entirely to my eating habits. I also spend a good amount of time in the gym, though I don’t workout nearly as much as I used to. But healthstyle extends to more than just diet and exercise.

Here I’ve compiled my favorite 30 habits to slow aging and keep you young in more than just your heart.

30 Healthstyle Tips To Keep You Young

1. Be happy The physical damage caused to your body by stress has only recently become appreciated by the scientific community. Fill your life with things you love and get rid of almost everything else. Practice stress relieving activities like meditation and exercise, and learn to appreciate joy when you find it. Happiness does a body good.
2. Eat vegetables There is good evidence that oxidative damage caused by toxins and metabolism contributes to the aging process at a cellular level. Foods (but not supplements) high in antioxidants seem to protect us from oxidative stress.
3. Avoid sugar Sugar is a direct cause of aging and significantly reduces lifespan in organisms from yeast to primates. Not by a small amount either.
4. Moisturize The appearance of your skin is largely dependent upon moisture. Help it out by using moisturizers to keep your skin soft and hydrated. Work with a professional to determine what type is best for you.
5. Don’t raise your eyebrows Credit my mother for teaching me this one, it has been a lifesaver. As a kid she used to warn me about raising my eyebrows, saying it would give me wrinkles and I’d regret it. I thought she was crazy, but still learned to express myself without much forehead crinkling. As a result I have far fewer forehead lines than some people years younger than me.
6. Sleep For me the most important determinant of how I look (and feel) on a given day is how much sleep I get. Seven hours is my ideal, but everyone is different.
7. Eat fish Some evidence suggests that the omega-3 fatty acids found in fish are particularly beneficial to the skin.
8. Wear sunscreen I love the sun and spend as much time in it as possible, but I never walk out the door without sunscreen on my face. UV radiation from the sun damages your skin and promotes aging.
9. Don’t smoke Smoking is one of the easiest ways to look older than you really are and shorten your life at the same time. Avoid both primary and secondary smoke like the plague.
10. Step out of your comfort zone Mental exercise seems to be one of the key elements of quality aging, but this doesn’t mean you should sit around all day doing crossword puzzles. Neuroscientist and cognitive aging specialist Dr. Adam Gazzaley suggests going out of your way to challenge yourself mentally, doing things like traveling and learning new languages even over the age of 60.
11. Take vitamin D Some research suggests that vitamin D may be particularly important in slowing the aging process. The jury is still out on the value of vitamin D supplements for aging, but they seem to have enough other benefits that it’s worth the investment.
12. Eat fruit Like vegetables, fruits have an enormous amount of antioxidants and help with hydration. Vitamin C in particular is thought to benefit skin.
13. No foundation or powder makeup Generally I avoid putting any makeup directly onto my skin. I realize I have a very flexible work environment and this is not possible for every woman, but skipping the makeup does help maintain your skin’s hydration and elasticity. I do wear makeup occasionally, maybe once or twice per week. But in general I find that mascara and lip gloss are enough for most situations.
14. Hydrate Your skin is very sensitive to water levels. Stay hydrated by sipping water and eating fruits and vegetables throughout the day.
15. Whiten teeth I know this isn’t something you can find at the farmers market, but when you drink as much coffee and red wine as I do, minor (and admittedly superficial) fixes like teeth whitening can go a long way. If you don’t believe me, try and remember the last time you saw a 20-year-old with yellow teeth….
16. Wear sunglasses If you’re a happy person (and I know you are), your wrinkles will most likely be caused by smiling and show up predominantly around your eyes. Block out extra sun (and look super cool) by always wearing sunglasses when you go outside.
17. Eat beans and lentils Legumes are a fabulous source of minerals that can help keep your skin hydrated and looking young.
18. Tea Afternoon tea time is one of the greatest discoveries I’ve ever made. Not only is tea full of antioxidants and other cancer-fighting compounds, a midday break can be just what the doctor ordered to sip away stress.
19. Cardio I’m not the biggest believer in cardio exercise for weight loss, but it is still important for vascular health. Not to mention how awesome you feel after a good session. Cardio doesn’t need to kill you, but you should do it regularly.
20. Strength training Building strong, toned muscles is one of the most effective ways to look younger than your years. Ask anyone who looks fabulous and they’ll swear by strength training. A little goes a long way.
21. Eat intact whole grains Intact grains (not fake “whole” grains that are ground into flour) are an excellent source of vitamins, minerals and soluble fiber. They are also perfect fuel for those killer workouts.
22. Olive oil It is hard to think of something more versatile, healthy and delicious than olive oil. It breaks my heart that dietary fat got such a bad rap the past few decades, since the benefits of healthy fats like olive oil are innumerable. Fat isn’t just “not bad” for you, it’s essential.
23. Kill your television We all have things we enjoy watching (I’m partial to NBA championship teams), but if it takes up a significant amount of your time each week (>5 hrs) it may be time to reevaluate. How many years of your life do you really want to spend on your couch?
24. Don’t stuff yourself Cutting back on calories is the single most effective way to slow aging and extend life. I don’t advise starving yourself, but it’s a good idea to avoid overeating in any situation.
25. Eat nuts Nuts are the perfect snack food and are filled with anti-aging fats, vitamins and minerals. They are also great for suppressing appetite–just don’t eat more than a handful.
26. Avoid dairy Studies of aging skin have shown that milk and milk products are associated with more aging and wrinkles.
27. Avoid processed meats Processed meats are associated with many different health problems in humans. No need to get too hung up on this, but you may not want to eat deli meat every single day if you want to stay young.
28. No processed carbohydrates Just like sugar, processed carbohydrates are a direct cause of aging and disease. I eat these things occasionally, but don’t let it happen too often.
29. Coconut oil Fats come in all different shapes and sizes, and I try to incorporate a good mix of all of them. Medium-chain fatty acids like those found in coconut oil are starting to be recognized as important by researchers, but the evidence is limited. Coconut oil is also a healthy source of saturated fat for vegetarians. I always use coconut oil when cooking Southeast Asian food.
30. Red wine Red wine has a powerful anti-aging compound in it known as resveratrol. Though it is unlikely that the dosage of resveratrol in red wine is high enough to impact lifespan, drinking alcohol in moderation is also associated with decreased risk of heart disease and other vascular problems. Cheers!

Do you have any anti-aging secrets?

1 lb Fat

Last week the New York Times and many other reputable news sources reported on a Canadian study that claims people with a normal body mass index (BMI) had a slightly increased risk of dying over a 12-year period than those with a BMI in the overweight range (25-29).

The use of the phrase “overweight was protective” landed this article just a hair’s width from being labeled Summer Tomato’s B.S. of the week on Friday. An observational study cannot determine cause and effect, as implied by the word “protective.” This study does not prove that extra body weight protects against all cause mortality, and saying so is irresponsible.

Studies (and reporting) like this have instigated wide-spread confusion about health and body weight. First people are told they are too heavy and should lose weight for health, then in the same breath they are told a little extra weight might not be so bad.

What is the average person supposed to believe? How should we act?

If you want to understand the facts it important to know exactly what the data does and does not say. Indeed, some studies (including one on Japanese men reported in the same issue of Obesity) have reported lower or equal risk of mortality for people with an overweight BMI compared to people of normal BMI (18.5-24). However, this is not the whole story.

First, the alleged benefit of being overweight has only been found in older individuals and does not apply to healthy, young people. Second, although it appears in some cases that overall mortality may be reduced, disease incidence is notably higher in overweight individuals compared to people of normal weight.

To point, a study in the most recent issue of Obesity (same journal, 2 weeks later) examines the relationship of BMI with many measures of cardiovascular disease in healthy, athletic men. In this study, those on the lowest end of BMI in the normal range (18.5-22.5) had a much lower risk of dying from or developing cardiovascular disease than normal weight men with a slightly higher BMI (22.5-25).

Men with the lowest healthy BMIs also had lower risk of hypertension, lower cholesterol and half the risk of diabetes. While the length of this study was only 7.7 years (compared to the 12 years reported in the Times story), there were more than double the number of participants (28,776 vs. 11,834).

(Why did this story not make the news? My guess is that it makes for a less compelling storyline and people would rather not hear it.)

Mortality is certainly an important measure in any study, but it is arguably not the most relevant endpoint. Disease and excess body weight can severely impact quality of life, particularly for older individuals (as illustrated by another study in the latest issue of Obesity). While I cannot speak for everyone, it seems probable that quality of life is equally if not more important than longevity alone. Thus it is questionable how much stock to put into studies that ignore these other factors.

It is also critical to remember that BMI is a measure that was designed to describe people at a population level, not as individuals. While large cohort studies can tell us useful things about relative risk, they are not directly applicable to individual people.

The inconsistency of the data related to BMI and mortality may in fact be an indication of its inadequacy as a general measurement. Remember that BMI represents a ratio between height and weight, making it possible to compare people of various body sizes. Normalizing for height may, however, be deceptive.

Decades of data on caloric restriction consistently show that smaller body size (irrespective of body fat levels and, possibly, BMI) is associated with longer life and decreased risk of nearly all diseases. This is true in all animals from yeast, to worms and flies, to mice and monkeys. While humans are certainly different from all these model organisms, there is tremendous evolutionary precedent indicating smaller body size as the best for health.

The principle of parsimony tells us the simplest hypothesis–that smaller body size is beneficial–is probably correct. Substantial evidence must be accumulated before this hypothesis can be rejected, and I have yet to see that data.

Furthermore, while the research on the risk of overweight may be slightly ambiguous, the data on obesity is not. It is painfully clear that the dangers of obesity are profound and on par with those of smoking cigarettes. Overweight is a necessary step to becoming obese, and according to the National Population Health Survey nearly a quarter of Canadians who were overweight in 1994/1995 were obese by 2002/2003. Since overweight is still a substantial risk factor for becoming obese, misleading public health messages about the benefits of body fat are especially dangerous.

As a consumer of information, the most important thing you can do is be skeptical of what you read. Just because something is printed in the New York Times does not make it true. In fact, many of our most trusted sources of health information do not base their recommendations on rigorous scientific thinking, which is probably the reason for the health disaster we are currently facing.

Thanks to Jan from Quest for Health for sparking this discussion.

What does your gut tell you about the relationship between health and body fat?

Tapeworm Diet Pills

Throughout history there has never been a shortage of (bad) diet, health and weight loss advice. Everything under the sun has been called a weight loss cure at some time or another. And now that we are blessed with the amazingness which is the internet, snake oil is more abundant than ever.

So who should you listen to?

Most people I speak to are so cynical about health advice they ignore all of it completely and simply hope they are one of the few blessed with the genetics to withstand decades of smoking, poor diet and/or no exercise. They always point to a great aunt who smoked like a chimney and lived to 95. At least she enjoyed her life, right?

The problem with this approach is that the vast, vast majority of us are not blessed with these genetics (sorry, being related to someone with those genes has very little effect on your own personal chances). Also, even if you have the most resilient body in the world the only way to test it is to do an experiment on yourself: Eat whatever you want and maybe you’ll make it to 60 without a heart attack. Maybe you’ll make it to 80 without colon cancer. Or maybe not.

It is also important to consider that no matter how long you live you can improve the quality of that life by making better decisions about how you treat your body now. And contrary to popular belief, these choices need not sacrifice fun and enjoyment. I for one consider my healthstyle habits–fresh delicious food and regular workouts–the best part of my daily grind. By far. The trick is finding a personal healthstyle that makes your life better, not worse.

But if bad advice is so abundant who should you listen to? Who do I listen to?

As hard as I tried, I could not come up with a way to describe someone who can be trusted for diet advice. I wanted to say “scientists,” but I could think of too many examples (usually involving money) where this simply isn’t true. Instead it is easier to think about who cannot be trusted and why.

10 People You Can’t Trust For Diet Advice

1. USDA Sadly, the government agency that has been given the responsibility of establishing the dietary guidelines for the United States is the Department of Agriculture. As you can tell from its name, the responsibility of this organization is to protect the interests of American agriculture industries. It has a far lesser interest in public health. Dairy and sugar lobbyists are the reason we are told up to 55% of our total calories can come from these sources. Obviously the USDA recommendations were not based on the data that clearly describes these substances as dangerous. Stay away from the bizarre food “pyramid” on their website.
2. Food companies When KFC tells you their grilled chicken is healthier for you than their fried chicken, do you believe them? How about Yoplait’s yogurt? Companies trying to sell you something are notorious for twisting scientific facts to make you believe their products are healthy. Think twice before you believe them, history tells us it is more likely the opposite is true (remember margarine and fat-free cookies?).
3. Your mom Although your mother has more interest in your personal health than lobbyists and food companies, she has been subjected to the same deceptive nutrition advertisements as you. A tragic fact of the past 60 years is that our parents grew up learning in school what the USDA wanted them to learn: calcium does a body good, fat = bad health, protein = good health. But these things are not true, no matter how strongly your parents believe them.
4. Celebrities It is difficult to look at a beautiful person and not believe they are doing something right or know some secret to perfect health. But just like your great aunt, celebrities have many advantages you probably don’t have that make their looks deceptive: genetics, time and money. These people make a living off looking beautiful and have all the resources in the world to achieve it. If they claim to have some secret to health or weight loss, chances are it is not something that will be effective in the long-term for a normal person. Even more likely is that they are being paid to sell you something.
5. Athletes If you are not a professional athlete or Olympian, chances are you do not have the same metabolism or dietary needs as someone who is. As much as I loved watching Michael Phelps win 8 gold medals, I am not going to start eating like him.
6. Cardiologists (or any M.D. with no research experience) Cardiologists are highly trained doctors that specialize in disorders of the heart and blood vessels. But while heart disease is strongly tied to diet, cardiologists are not necessarily trained in science or nutrition. I do not wish to take anything away from what these individuals do–most are incredibly talented, skilled professionals. However medical school and residency training focus more on treatment than prevention. Moreover, science (Ph.D.) and medicine (M.D.) are different, and few doctors have the time or training to keep up with and evaluate nutrition science. But some certainly do, and it is worth it to find out who. Another thing to consider is that heart disease is only one chronic disease related to diet. If you are worried at all about cancer, stroke, diabetes or Alzheimer’s disease would you ask a cardiologist?
7. Main stream media We all love a good story and journalists are trained to sell them to us. But very few journalists–even science writers–have more than a bachelors degree in biology or other hard science. This, of course, is less than the doctors I mentioned above. Though journalists are often very intelligent and can do a great job of analyzing the available scientific evidence (Michael Pollan comes to mind), even my beloved New York Times can drop the ball on nutrition science on occasion. When push comes to shove, they are more trained in story telling than scientific analysis.
8. Personal testimony We are all impressed by the person who lost 200 lbs on the Biggest Loser, and I salute anyone who has ever achieved substantial weight loss. But all diet advice from these people should be taken with a grain of salt. Personal testimony is the ultimate in non-scientific fluff (check out any website selling diet pills). In science a personal testimony is called N=1 and is proof of absolutely nothing. These people may be a great source of moral support, but real evidence and facts have numbers and statistics tied to them.
9. Natural health “gurus” Cynicism about health, medicine and science frequently cause people to turn to “alternative” solutions that often involve “natural” remedies. I would never suggest that natural solutions might not be the best path to health, but something being “natural” is not a guarantee of any particular benefit. In my experience, advice from natural health “gurus” is often based on poorly designed, poorly controlled studies that do not stand up to rigorous scientific testing. That does not mean these methods will never be proven effective, but keep in mind that most of them never will.
10. Personal trainers The gym is one of my favorite places in the world, and if I need help with a certain exercise I ask a personal trainer. Most trainers have (hopefully) gone through a (fairly easy) certification program where they learn the basics of body mechanics. They are not scientists and are not trained in nutrition.

I am not suggesting that these people contribute nothing to our conversation about diet. However you should always be skeptical of who you take your advice from, particularly when it comes to your health.

Is there anyone you would trust for diet advice?

Read my answer….

Vegetables

Most scientists agree that diet plays an important role in heart disease, but until now there has been no comprehensive analysis of which dietary factors most strongly affect disease outcome. A new meta-analysis published in the Archives of Internal Medicine reviews six decades of research (1950-2007) to assess how different dietary factors affect heart disease. Vegetables, nuts, “Mediterranean” and high-quality dietary patterns are strongly protective, while trans-fat, foods with high glycemic index or load and a “Western” dietary pattern were shown to be harmful.

The Study

This new study is unique for several reasons. First, the authors were only interested in factors that influenced heart disease directly, not simply heart disease risk factors such as cholesterol levels. Also, emphasis was placed on high-quality studies designed to identify strong dietary associations (cohort studies and randomized controlled trials) with long periods of follow up (at least one year). They asked whether the studies they reviewed were consistent with other data such as epidemiological reports, and sought to establish a causal link between diet and heart disease outcomes. Another important goal of the analysis was to identify factors that lack sufficient evidence to be conclusive and require further research.

Results

In addition to identifying vegetables, nuts, high-quality and Mediterranean dietary patterns as being strongly protective against heart disease, they also found monounsaturated fats (e.g. olive oil), dietary folate (e.g. whole grains, not supplements), dietary vitamins C and E (not supplements), alcohol consumption (in any form) and omega-3 fatty acids from fish (not plants, e.g. flax) to be moderately protective.

Factors that were not associated with heart disease in this study were dietary supplements (e.g. vitamins C and E), total fat, saturated fats, polyunsaturated fats (from plants), meat, eggs and milk. It is important to note, however, that negative findings in this analysis are not necessarily indicative of a lack of causality. Rather, it may indicate insufficient data to observe a significant positive association.

Dietary Patterns

The authors point out that “only overall healthy dietary patterns are significantly associated with coronary heart disease” in the controlled trials, while “evidence for most individual nutrients or foods is too modest to be conclusive.” They suggest that the reason an association exists for dietary patterns and not individual nutrients is that patterns “have the advantage of taking into account the complex interactions and cumulative effects of multiple nutrients within the entire diet.” The authors recommend future trials test various dietary patterns for disease outcome, including cardiovascular disease and cancer.

Taking this further, most dietary factors that were shown to be protective when consumed as part of a healthy diet were not protective when taken in supplement form. This finding bolsters the argument that overall diet rather than individual foods or nutrients are the best strategy for protecting against heart disease. The authors conclude that their findings suggest “investigating dietary patterns in cohort studies and randomized controlled trials for common and complex chronic diseases such as coronary heart disease.”

Based on their analysis, the dietary pattern that best protects against heart disease is rich in vegetables, nuts, fish, healthy fats, whole grains, and fruit. Likewise, the worst dietary pattern consists of refined carbohydrates and artificial trans-fats. The lesson: the best diet consists of plants, fish and whole foods, while processed foods contribute to heart disease.

What about red meat and saturated fats?

Interestingly, there was insufficient data to conclude that red meat or saturated fats are harmful for the heart. This is not terribly surprising, since the data has always been inconsistent. However, I would point out that many studies have looked at the role of red meat and saturated fat in coronary risk and the outcome always shows either harm or no result. And as explained above, no result can be indicative of a lack of statistical power rather than lack of causation. Importantly however, I cannot recall a single study suggesting that red meat and saturated fat is actually good for you.

From this the best we can conclude is that red meat or saturated fat may be involved in promoting heart disease, but if they are the effect is likely to be less harmful than a diet of processed foods. Practically this means small doses of saturated fat may not do much harm when eaten as a part of an overall healthy diet. This is a fairly compelling argument for exercising moderation.

Conclusions

Before you run out and order a ribeye, keep in mind that heart disease is not the only debilitating chronic disease that plagues our culture. Red meat is also associated with several kinds of cancer. Likewise, refined carbohydrates are highly correlated with type 2 diabetes. Vegetables and whole grains are protective against these other diseases as well, and fish may play a role in protecting against neurodegenerative diseases.

The take home lesson is that both diet and disease are complex systems that involve innumerable factors in several different regions of the body. When choosing what to eat it is important that you consider the context of your overall diet and do not get caught up is single foods or a single disease threat.

Collards, Carrots and Lentils

Once you have everything you need to cook healthy meals, you are well on your way to a better healthstyle. But first let’s stop and make sure we know what a healthy meal looks like.

Part one is Stock Your Pantry, part two is Essential Groceries, part three is Seasonal Shopping and part four is Stock Your Freezer. The recipe pictured is posted here.

My goal here at Summer Tomato is to help you permanently adopt healthy eating patterns. Why? Because short-term weight loss diets, “cleansing” diets and ignoring your health completely will never do you any good. In contrast, healthy eating habits can add years and in some cases decades of high-quality time to your life.

I am not being sensationalist. The data is very convincing that your eating habits are the most important factor in your long-term health.

For many people the first big step in getting healthy is losing weight, and this means eating better and eating less. But my advice is generally the same (with a few exceptions) if you are not overweight. Healthy eating is the same for everyone–eating for fat loss and eating for health and longevity are the same thing.

How can you permanently eat better?

You cannot expect to let yourself go hungry and stick to that eating plan forever. It is therefore critical that you get the most out of your meals by making sure they have enough nutrients and flavor to keep you satisfied. I would go so far as to say you should love the food you eat and should walk away from it not wanting another bite. With balanced meals and wonderful ingredients, you can feel this way about what you eat.

Your body needs many things to function properly. It runs on complex carbohydrates, vitamins, fats, fibers, minerals, proteins and probably many more things we have not yet discovered. If you follow some trendy diet that encourages you to eliminate one or more of these, your body will feel deprived and ultimately find a way to get what it wants (usually in binge form). So let’s forget the starvation option and instead choose foods that give us all the nutrients we need. What we will reduce (not eliminate) are foods with fewer nutrients, the ones your body can be happy without. These foods will be addressed in a future post.

The best strategy is to give yourself a steady supply of what your body needs throughout the day. Every day. And because scientists have been unable to replicate a healthy diet with a pill, we need to focus on eating food. Real food. The kind that comes from the earth, not from a drive-thru.

The following is a guide to creating a perfect, healthy meal from food. It is only meant to be a blueprint, not a rigid plan. But I feel it is important to spell this out at the beginning because it is so different from how most people eat. I can assure you that it is very doable and more than satisfying. I eat this way, and I can say without hesitation that food is my favorite part of my day.

Note: These recommendations are largely based on Dr. Walter Willett’s healthy eating pyramid outlined in his book Eat, Drink and Be Healthy, still the best book on health and diet I have read.

Eat Your Vegetables

Size Matters

As I alluded to in my post on seasonal shopping, the bulk of your diet must be vegetables if you hope to permanently lose weight and avoid heart disease, diabetes, cancer and dementia. The science is very clear on this point. If you do not like vegetables, I suggest you try and learn to like them. Chances are you have not eaten many high-quality vegetables from your local farmers market or that the ones you have tried were not prepared very well. Keep trying! Explore different recipes. Try different vegetables at high-end restaurants. Go out of your way to find vegetables cooked a way you like (preferably without cheese).

Here are some tips on learning to love foods you don’t like.

I recommend finding a friend who loves to cook and inviting him or her to explore your local market together–the enthusiasm of a chef at a farmers market can be contagious! You could even volunteer to help make a meal afterward with the fresh ingredients you found. It is amazing how quickly a kitchen becomes demystified when you spend a little time in one. Start with simple recipes. Delicious food does not have to be complicated if you cook with wonderful ingredients.

To reiterate, your first task is to increase your vegetable intake. Aim for about half of your (medium-sized) plate to be covered in vegetables. Make this happen for both lunch and dinner. If for whatever reason your choice of meal makes this difficult, try to get at least some green on your plate. Adding kale or spinach to whatever you’re making is usually pretty easy.

Diversify

You also want to try to get as much diversity as you can in the types of vegetables you eat. If you have seen those obnoxious lists of “superfoods,” you may have started to realize that any fruit or vegetable can be considered super. The fact is that all vegetables have some unique benefit and you maximize your health by eating many kinds of them, not by eating a lot of one kind. I try to mix up my weekly shopping cart to reflect the diversity of the farmers market, and I usually try to buy something I have never eaten before.

One wonderful thing about seasonal shopping at your local farmers market is that vegetables and fruits come and go pretty quickly, so diversity comes with the territory.

Smart Protein

I mentioned above that it is important to feel satisfied by your meals, and protein can go a long way in helping you achieve this. However, there are many misconceptions about protein, particularly regarding how much and what kinds you should eat.

I’ll start by saying that virtually no one in the Western world is protein deficient. It is relatively easy to get the protein your body needs to maintain its muscle mass. I do not recommend counting protein grams unless you are a professional body builder, in which case this probably isn’t the best website for you.

Despite what some people may say, many vegetables and grains contain protein. For instance, a cup of brown rice has 5 grams of protein. A cup of black beans has 15 grams of protein (and 20% of your daily iron). Some will argue that these are not “quality” sources of protein because they are not “complete proteins,” meaning that they are lacking in some essential amino acid. However, this argument is irrelevant if you follow my advice above and enjoy diversity in your diet. Yes, if all your protein comes from brown rice then you may be deficient in lysine, but presumably you are eating more than just brown rice and the rest of your food will easily make up the difference.

Getting all your protein is important, but since it is relatively easy to get I find the biggest value of protein is helping you feel satisfied after a meal. Protein digests more slowly than carbohydrates and can help you feel full longer. From this perspective, it matters very little where your protein comes from.

If you choose to get your protein from animal sources like fish, eggs, poultry or red meat, your portions should be relatively small or your calorie consumption will begin to increase substantially. 4 oz of meat, or about one quarter of the space on your plate should be from protein.

Personally I try to get my protein from beans, eggs or fish, because they offer more than just protein. Beans are a great source of fiber and iron. Eggs are a perfect size and are rich in vitamins. Fish has wonderful oils that have been shown to protect your heart and brain.

I’m fairly neutral on poultry and red meat in small quantities. Too much meat, however, can be a serious problem and is associated with osteoporosis and several kinds of cancer. It is also very expensive. I do not drink milk, which will be the topic of a future post.

Intact Grains

Despite what disciples of Dr. Atkins may say about carbohydrates (a lot of which I agree with), intact whole grains are essential to a healthy diet. Unfortunately, real whole grains are not very easy to come by in our culture. I have explained before, there is a tremendous difference between an intact whole grain that still looks like a grain and the “whole grains” in Lucky Charms that have been mutilated then reassembled. Real, intact grains digest slowly and are an essential source of fiber, vitamins, minerals and other wonderful things.

Like protein, whole grains should comprise about a quarter of your plate. However, since whole grains are rather difficult to get, I usually choose to make intact grains the bulk of my breakfast, and usually incorporate other grains such as brown rice or quinoa into either lunch or dinner. These will also go a long way to increase the satisfaction you feel from a meal.

Healthy Fats

One of the reasons the low fat diet from the 20th century failed so miserably is that it did not account for the necessity of healthy fats. Oils from plants and fish are critical for protecting against disease. And, like protein and grains, they contribute greatly to how satisfying your meal is.

Because fats have a high caloric density, a little really goes a long way and there is no definitive space on your plate that I allot to them. However, generally I recommend dressing or cooking all your vegetables in olive oil or canola oil. I also recommend cooking with nuts (many different kinds, of course) regularly and enjoying avocado and other oily plants frequently.

Fish provide a different kind of oil than plants, and both are important. But if you are eating substantial amounts of fish you should be aware of the dangers of mercury contamination.

Conclusion

Strive to eat a diverse array of fresh vegetables, healthy proteins, intact grains and plant and fish oils as a part of your daily healthstyle, particularly in the meals you have control over. However, this is not something you should approach as all-or-none. Any meal can be made more healthy by adding these ingredients, and it is worth it to work them in if possible.

But most important, be sure that whatever you eat you enjoy. None of this is “diet food” and all of it should make you happy.

Pantry

Nothing has a bigger impact on your health than the food you choose to eat (unless you smoke cigarettes). A diet rich in whole vegetables, grains, legumes, fish and fruit can prevent and even reverse most of the diseases that devastate our society. The good news is that farm-fresh, seasonal produce happens to be some of the most delicious food on the planet.

Unfortunately, our culture does not make it easy to eat foods that are both healthy and delicious. Your typical grocery store is filled with processed, packaged junk that barely resembles the plants and animals it came from (usually corn and soybeans). Even the produce section is populated with clones shipped from halfway around the globe.

But eating healthy is not impossible. I manage to pull it off, despite a long-ish commute and impossible work schedule. All you need is a little planning and a road map.

For many people the most difficult thing about starting to eat healthy is learning how to prepare and cook food. Unless you happen to live down the street from Café Gratitude, you are not going to be able to upgrade your healthstyle by eating in restaurants. You have got to be able to shop and cook for yourself.

This is the beginning of a series of posts designed to give you detailed instructions on How To Get Started Eating Healthy. It is the perfect place to begin if you are new to Summer Tomato. Once you have learned to integrate these instructions into your normal routine, nothing on this blog should pass over your head. You will be able to follow any recipe, conquer any ingredient, get healthy and love every minute of it.

Keep in mind I was once as clueless in the kitchen as I was at the farmers market. I found my healthstyle through trial and error and created Summer Tomato to share what I have learned.

If you are beginning with a barren kitchen and are not sure what you need to get started, check out the Summer Tomato Shop. Once you are there, use the navigation in the sidebar on the right and browse through Kitchen Gear. I consider the items listed in the Basics category to be essential for elementary cooking. The ones in Accessories are also super useful. The snobbier among you (that’s a compliment) might have fun searching The Finer Things.

Once you have all your pots, pans and cutting boards you need to Stock Your Pantry. I have created a list of essential items that should always be in your kitchen. Because these things all store well and can be purchased in large quantities, you do not need to buy them often. But check your supplies regularly and be sure you always have everything here:

• Olive oil You really cannot cook anything until you have olive oil. I go through olive oil relatively quickly, so I am sure to buy large bottles. Look for cold-pressed olive oils in dark bottles. For cooking I try to get the highest quality oil I can find at a reasonable price. My current favorite is Whole Foods 365 Organic brand extra-virgin olive oil. I buy the full 1 liter bottle.
• Sea salt Whenever I come across vegetables I do not like they tend to have two things in common: they are 1) over-cooked or 2) under-salted (or both). But salt is bad for you, right? Yes, it is bad to eat the inconceivable volumes of sodium present in processed and packaged food. But you would be hard pressed to ingest that much salt if you add it yourself. It is possible to over-salt your vegetables, but under normal circumstances you can determine the appropriate saltiness by taste. In contrast, processed food tastes gross (grosser, I should say) without salt. You can add a reasonable amount of delicious sea salt to natural foods to enhance their flavor without much worry. Sea salt helps make fresh vegetables taste amazing, and if you eat them you are substantially better off. (note: If you have very high blood pressure, potassium salt might be better for you. Talk to your doctor about your options.)
• Pepper Pepper is an essential spice you should always have in your pantry. It has better flavor if it is freshly ground.
• Vinegar Frequently the easiest way to salvage a struggling dish is to add some kind of acid. Acid has a slightly sour flavor that can help brighten a dish. Vinegar and lemon are the go to choices for most cooks, so you need to have them around. Vinegar (and oil) is also what I use to dress salads. Balsamic vinegar is particularly wonderful because of its sweetness. But if you don’t like it experiment until you find a vinegar you like. Red wine vinegar is my next recommendation. Rice vinegar is also handy to have around, particularly if you like cooking Asian cuisines.
• Fancy olive oil Speaking of salads, I always keep a top-shelf, fancy olive oil in the house for when the dish I’m creating depends on olive oil itself for flavor. Salad is the most basic example, but there are many instances where a better oil is worth the investment. You should enjoy the taste of your food, a few extra dollars for an outstanding olive oil is more than worth it.
• Soy sauce One of the easiest ways to change up the flavor profile of a dish is to add a splash of soy sauce. You should always have some. Keep it in the fridge after opening it though.
• Whole grain cereal I have found it incredibly difficult to find cereals–even whole grain cereals–that aren’t loaded with sugar. Muesli is my best recommendation, but it usually needs some help in the flavor department. I add fruit to fix this. Oatmeal (stove top) is a perfect breakfast if you have time for it (10 minutes). Whatever you choose, make sure you find a cereal made of intact grains that you are happy to eat most every day. For variety, I alternate between cold and warm cereals and change the fruit I use with the seasons.
• Assorted whole grains Intact grains are so old-fashioned these days they are pretty hard to come by. If you do not eat them at home, you will almost certainly never eat them. Brown rice and quinoa are the two I rely on most. Quinoa cooks easily in 15 minutes. Brown rice takes longer, but I make it in large batches and freeze it in single servings that microwave in 1 minute. I also keep whole grain couscous around, even though it isn’t a real whole grain. I just love it in Moroccan food.
• Dried legumes Legumes are some of the healthiest foods on the planet, and are notoriously under-appreciated. Lentils and beans are not just a vegetarian protein source, they are essential to a healthy diet regardless of carnivory. One benefit of them being out of fashion is that they are incredibly cheap and can usually be purchased in an unadulterated form. Lentils are wonderful because they cook quickly, in about 20 minutes. There are many varieties of lentils with different purposes. I recommend starting with regular brown or French green lentils because they keep their shape well. Beans require soaking and still take at least an hour to cook, unless you have a pressure cooker (I couldn’t live without a pressure cooker now). You can buy canned beans if you prefer, but they are far more expensive and have inferior taste and texture.
• Bouillon cubes I had never heard of these until I started cooking, but I use them pretty regularly now. Bouillon cubes are essentially dried, concentrated broth. I keep chicken bouillon around for couscous and soups. Beef bouillon tastes amazing and I love to add it to beans and richer dishes. They make veggie bouillon too. You can get these everywhere, probably even your local liquor store.
• Boxed broth Since these keep for at least a year, it is good to always have a few boxes around. Soups are great to whip up for dinner when you are tired and don’t feel like cooking anything fancy. If you always have broth, you can always have soup. I buy the 1 qt chicken and veggie broths. The smaller boxes or cans are good for making sauces.
• Canned tomatoes I keep at least one 28-oz can of diced tomatoes at all times. Canned tomatoes are the base of so many different cuisines and make for wonderful meals. Tomatoes are, ironically, one of the few canned vegetables that don’t repulse me.
• Nuts You should see the shoebox I use to store all the nuts I buy, it is bursting at the seams. Nuts are healthy, filling and turn food from average to awesome. I throw cashews in stir frys, cook my chard with pistachios and have almonds for a snack almost every day at work. Get in the habit of cooking with nuts or adding them to salads rather than just eating them plain. My kitchen always has raw walnuts (store in the freezer, they go rancid the quickest), roasted unsalted pistachios and sliced almonds. Hazelnuts, macadamia nuts and peanuts are also wonderful. Go nuts!
• Dried fruit With plump, juicy raisins in my oatmeal I do not need to add sugar or honey. Dried apricots are wonderful in Moroccan soups or couscous. Dates are a great after dinner treat. Dried fruits store well and come in handy, you should keep the ones you like around and be creative with them while cooking.
• Canned fish My canned fish of choice lately is sardines. Sardines are incredibly rich in omega-3s and vitamin D. When skinless and boneless, they are also delicious on bread or in a stir fry. My second choice is canned salmon (again, please get boneless–even if it costs extra). Tuna is okay, but it is too high in mercury for me to eat it at the frequency I prefer (you should limit tuna to 1-2 servings per month, particularly if you are a woman of childbearing age). Salmon is high in omega-3s and lower in mercury than tuna. I eat canned fish 2-3 times per week.
• Basic spices When I first discovered cooking I went to the seasoning aisle of my grocery store and bought every spice and herb I had ever heard of. This was a mistake. I have since learned that most of the ones I bought are much better fresh (e.g. parsley, sage, rosemary and thyme). But there are a few spices I still use a lot. I always keep Saigon cinnamon, cayenne pepper, chili flakes, coriander, cumin (seeds and powder), ground ginger, garlic salt and chili powder in the house. I recently got a spice grinder, so sometimes I grind my own. But these are spices that are good to have around.
• Natural nut butter Almond butter on good bread is one of my favorite quick, filling midday snacks. It is high in calories, but very effective at curbing the appetite. I always keep an unopened jar in my pantry. If you buy the natural kind (which you should), refrigerate after opening.
• Pasta I know it sounds sacrilegious, but I do keep pasta in my pantry because sometimes it is just the easiest option. A healthy-ish choice is Japanese soba noodles that are made from buckwheat rather than semolina. I do not have pasta very often, so I do not worry too much if I eat it occasionally.
• Plastic wrap and zipper bags I know these aren’t food, but I consider them essential items that need to be stocked regularly. I also happen to keep mine in the pantry. Don’t forget to buy them!

Once you have these basic ingredients you are ready to start cooking for yourself. In future posts for the How To Get Started Eating Healthy series I will discuss items you need to regularly stock in your refrigerator and freezer. I will also explain how to shop seasonally and outline a few basic cooking techniques you can use to cook almost anything.

Please do not consider this list exhaustive. This is simply a blueprint for how to get started stocking your pantry to cook healthy food.

I encourage you to share your favorite pantry items and tell us what you use them for.
