10 People You Can’t Trust For Diet Advice

Tapeworm Diet Pills

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?

How To Cook With An Unfamiliar Ingredient

by | Apr 27, 2009
Amaranth

Amaranth Leaves

Last week a new farmers market started up at the UCSF Mission Bay campus where I work. As someone who makes it my business to know what’s happening at our local markets, I was very interested to check out what they were offering. To my surprise and delight, there was a tremendous variety of interesting, high-quality goods and produce. But I already had a bunch of fresh groceries at home from my Saturday market trip, so I only purchased a few special things I just couldn’t resist.

The first thing that caught my eye were the beautiful Asian greens I spotted at the beginning of my exploration (sorry, I’m not familiar with these farms yet so I do not remember the name). I had never seen okra or bitter melon leaves for sale before, though I am familiar with these vegetables. What really grabbed my attention though were these beautiful amaranth leaves.

I had always considered amaranth a grain, and did not know it was also a leafy vegetable. But apparently amaranth greens are incredibly popular in India, Africa, China, Vietnam and Greece. The leaves are fairly delicate and I would describe the taste as similar to spinach if spinach were Indian. In other words, the leaves have earthy and spicy undertones reminiscent of chai tea. Needless to say I was very excited to see what I could make with them.

When I got home with my greens I did a quick Google search for amaranth leaves recipes and virtually everything that came up on the first search page was for Indian dishes–perfect! I read through a few of them and realized that the most common use for amaranth leaves is in a lentil dish with spices and tamarind.

Since I had most of the required ingredients in the house, I decided to give it a try. Not too long ago I purchased an assortment of red and yellow Indian lentils from a specialty store in my neighborhood. Usually I have concentrated tamarind in my refrigerator for those occasional Thai food cravings. I didn’t have the fresh tomato most recipes called for, so I used half a can of diced tomatoes from my pantry (I used the rest in my roasted fava beans dish). I also keep standard Indian spices in the house such as cumin seeds, garam marsala (a traditional Indian spice blend), curry powder, tumeric and ghee (clarified butter).

See how easy it is to be creative when you have a well-stocked pantry?

The dish turned out amazing, and the batch I made was so large I have been eating it for days (not bad for a $2 ingredient). But I am not going to give you the recipe, because that is not the purpose of this post. Instead I wanted to give you an idea about how I approach shopping and cooking. If something is unique or catches my eye at the market, I inquire to the vendor about what it tastes like and how it is used. When I get home I look up recipes online until I find one or two that look yummy and are not too hard to make. Sometimes this involves changing the recipe slightly to match the ingredients I have available, or combining two or more recipes together to accommodate my own modest cooking skills or time allowance.

You do not have to be a brilliant chef to explore cooking this way, and you will certainly get better at it the more you practice. The key is digging through Google until you find a recipe that doesn’t scare you too much. You can also try services such as Recipe Puppy that allow you to type in an ingredient and receive a collection of recipes from around the internet. Recipe Puppy didn’t work particularly well for amaranth (no results), but it is useful for most ingredients and can be a terrific source of inspiration.

Next time you shop, go out of your way to find something you haven’t cooked before and see what you can come up with. Who knows, you may actually find a new favorite food and upgrade your healthstyle in the process!

Don’t forget to come back and let us know what you learned. Tell us your favorite accidental ingredient discovery!

Farmers Market Update: Height of Spring

by | Apr 26, 2009
Fava Beans

Fava Beans

If you have been meaning to go to the farmers market but still haven’t gotten around to it, I strongly suggest you make it happen next week. Some of these Spring treats are only available a few weeks out of the year, and they are peaking right now.

This week I bought young fava beans from Iacopi Farm. Normally fava beans require a substantial amount of work to prepare, including shelling, blanching and removing the tough skin of each bean with a pairing knife. When young however, fava beans can be roasted and eaten whole. Last night I put mine in the oven with tomatoes, green olives, chili flakes and anchovies, then sprinkled on capers, parsley and lemon juice when I pulled them out. It was amazing.

Baby Artichokes

Thumbalina Carrots

Strawberries are also particularly special right now. At Dirty Girl Produce I found strawberries from both first year plants and second year plants, and I was astounded by the difference. Apparently as strawberry plants get older they produce smaller, sweeter, more concentrated fruit. These made for the most intesely flavored berries I found at the market. The young berries were also wonderful though, big sweet and more juicy than the second years. I bought both. Can you tell which is which?

Shell Peas

1st & 2nd Year Strawberries

The flowering kale rabe was gone this week, but asparagus is available in all sizes and colors. The variety of onions right now is remarkable.

Finally, since I have been interested in Moroccan cooking lately I have been reading a lot about an ingredient called preserved lemons. I bought one this week from Boulette’s Larder and used it to make the best hummus I have ever had in my life.

Quick Fix: Collards, Carrots and French Green Lentils

by | Apr 24, 2009
Collards, Carrots and Lentils

Collards, Carrots and Lentils

Last week I wrote about the perfect balanced meal and featured a picture of my dinner the previous night: collard greens, carrots and French green lentils. Since then I have had more than a few requests for the recipe and am happy to provide an encore to the How To Get Started Eating Healthy book.

Lentils are incredibly nutritious and easier to cook than dried beans. They also have the third highest protein content of any plant. A single serving of lentils contains 18 g of protein, 63% of your daily fiber and 37% of your iron in only 230 calories!

That’s more iron than 1,123 calories of prime rib. Remember when I said every plant could be considered a superfood? Well, lentils are no exception.

Lentils and other legumes are also great for weight loss and are a fabulous alternative to grains for individuals who are insulin resistant or diabetic, since they have minimal impact on blood sugar.

For a pan cooked dish, you want lentils that are fairly robust and maintain their shape after cooking. I prefer French green lentils, but standard brown lentils also hold up pretty well. Simply boil them in excess water with a pinch of salt for 20 minutes or so until tender (do not overcook). Strain, then toss them in with your vegetables at the end of cooking just to coat with flavor and heat through. Lentils freeze well, but can be kept fresh in the refrigerator 3-5 days.

In this recipe, kale or chard can easily substitute for the collards. If you want to use spinach, add it last after the lentils. Fold it in and allow it to wilt into the dish.

Collards, Carrots and French Green Lentils

Ingredients:

  • 4-5 collard leaves
  • 4-5 medium carrots
  • 1/2 cup French green lentils, cooked
  • 1 small leek
  • 1 clove garlic
  • olive oil
  • sea salt
  • lemon juice (optional)
  • chopped parsley (optional)

If you are making your lentils from scratch, quickly pick through them for pebbles, give them a rinse then boil them in excess water with a pinch of salt for 20-30 minutes, until tender. Even though I rarely consume more than half cup (cooked) in one sitting, I usually like to cook up at least one cup dry (at least 4 servings) and save the rest for later. Start them boiling as soon as you step into the kitchen and start cooking your vegetables at least 15 minutes after you turn them on.

In the mean time clean and chop your leek and mince your garlic. Peel and slice your carrots at a sharp angle to maximize the surface area for cooking. Clean your collard leafs, chop off the stems then stack them on top of each other in a pile. Cut into one inch squares, removing any sections that have thick pieces of stem.

Heat a pan on medium heat, then add olive oil. When the oil swirls easily in the pan, add the leeks and allow to cook for 1-2 minutes, until the pieces break up and become tender and translucent. Add carrots and stir. Cook 2 minutes, then add collards. Sprinkle with sea salt and continue to cook, stirring occasionally.

Be careful with your heat when pan frying collard greens–don’t let it get too high. The leaves easily trap steam from cooking, and I had a few jump out of my pan onto the floor. They make a loud popping sound too, which is very exciting. If it makes you feel safer, you can cover the greens for the first minute or two while they soften.

Shortly after the collards turn bright green from cooking (4-5 minutes), clear a space in the center of the pan and add your minced garlic in a single layer (you can add a touch more oil if necessary). Let garlic cook 30 seconds or so until fragrant, then add the lentils and mix with the other vegetables. A squeeze of lemon juice, zest or a dash of vinegar is a good addition here, if you like. A sprinkle of your favorite herb, e.g. Italian parsley, basil or thyme, adds depth and complexity if you have them around.

Continue cooking 3-4 more minutes, stirring every 30 seconds. If you are using cold lentils, cook until warm. Adjust salt and serve.

This dish is wonderful as a main course, by itself or with brown rice. It can easily be scaled to accommodate a large crowd if you have a big enough pan.

What flavors do you love to pair with lentils?

How To Get Started Eating Healthy: Foods To Avoid

by | Apr 22, 2009
Junk Food

Junk Food

What truly liberated me from worrying about food all the time was shifting my thoughts and fears away from things I couldn’t or shouldn’t eat and instead focusing on delicious foods–foods I love–that also make me healthy. Changing my relationship with food in this way turned it from something that caused me anxiety to something that brought me pleasure.

One unexpected benefit of choosing healthy, tasty foods over bland diet foods was that many of my old cravings for sugary, unhealthy fare disappeared. While I have not found a clear scientific explanation for this, it stands to reason that a nourished body would be less prone to strong feelings of need toward certain foods. I was amazed how powerful it can be to focus on health instead of dieting. These days, really unhealthy foods barely even tempt me.

Part one is Stock Your Pantry, part two is Essential Groceries, part three is Seasonal Shopping, part four is Stock Your Freezer and part five is Balanced Meals. Get future posts by signing up for email or RSS updates–always free of cost and spam.)

Upgrading your healthstyle will go far in helping you overcome your cravings, but as I much as I would love to tell you that you can eat any foods you want in any quantities you want, we all know this is not true. While you are focusing on eating more of the foods you love there are also foods that are generally worth avoiding as part as your daily healthstyle.

There is room for anything in a healthy life, but here are some foods that DO NOT promote health and can lead to weight gain:

  • Sugar In any form, sugar wreaks havoc on your health and metabolism. Two keys to protecting yourself from sugar damage are quantity and timing. Do not eat too much sugar at once (stick to small desserts) and do not eat sugar very frequently. I try to limit real desserts to once or twice per week (max) and satisfy all other sweets cravings with fruit. Eating whole grains is particularly effective at reducing sugar cravings.
  • Refined flour Processed grains (all flour) are almost as bad as sugar in their effect on your metabolism. In fact, your body processes them exactly the same way. Generally look for alternatives to breads, pastas and other foods made with flour. Instead focus on getting carbohydrates from intact whole grains. Try to limit refined flour foods to less than once per day. If you are actively trying to lose weight, I would make an effort to cut these out completely.
  • Trans fat Twenty years ago scientists believed they had solved the problem of saturated fat by replacing it with an artificial solid fat made from plants. It turned out these processed fats, trans-fats, are one of the most dangerous foods you can put into your body. Not only do they raise your “bad” LDL cholesterol, they also contribute to lowering your “good” HDL cholesterol–a double whammy for your health. No amount of trans-fat is considered safe in the diet (the data is striking), and you should avoid these processed fats completely. Better to eat foods made with real butter. Better yet, choose healthy fats from vegetable sources like coconut oil, olive oil and canola oil.
  • Anything processed It is worth emphasizing that nothing processed has ever proven to be healthier for you than real whole foods–even foods with fantastic health claims on the package. In fact, as Michael Pollan points out in his book In Defense of Food: An Eater’s Manifesto, a health claim on a package is a pretty good sign that a food is bad for you. There are no stickers for “Whole Grain” or “Low Carb” on your vegetables, and those are what you should be eating.
  • Red meat As I discussed earlier this week, red meat is probably not good for you. Some people argue that it is really bad for you, and some people think it is not so bad. It appears to not be quite as bad as processed foods, but there are plenty of compelling reasons to limit how much red meat you eat. For myself personally, cancer is a bigger fear than heart disease. But there is also some data that saturated fat plays a role in insulin resistance. I recommend less than one (4 oz) serving of red meat per week. The same can be said about poultry with skin.

I do not recommend completely eliminating foods you love–even if they are bad for you–because this is not something you can maintain forever and it strips some of the joy from life. Instead I suggest trying a few customizable strategies to be sure that the less healthy foods you love bring you happiness, but do not damage your body:

  • Reduce, Don’t Eliminate Simply being aware of how often you eat these foods and trying to stick to the guidelines above can drastically improve your healthstyle. If you currently eat a lot of sugar, processed foods or red meat, do not attempt to completely overhaul your diet overnight. Make changes gradually or it will be very difficult to make them permanent.
  • Be Picky When you first start to upgrade your healthstyle, identify foods you can do without and those you can’t live without. Some changes will be easier for some people, while others are nearly impossible. Focus on the easier changes and do not beat yourself up over things that are difficult for you. Every little change you make will add up to a healthier you.
  • Set Up Simple Rules It is often hard to keep track of everything you do or do not eat. A food journal or Twitter can help with this, but the simpler your healthstyle the better. Setting up simple, easy to remember rules for yourself can help you make healthy changes. The guidelines above are a great place to start. For example, if you decide in advance you can only have one dessert per week, you can be sure that the one you choose is well worth the wait. Use simple rules to both increase your good habits and decrease your bad ones. Experiment to find simple rules that work for you. For example, if you love to eat pizza make a deal with yourself that if you have it you must have a big pile greens on the side–this may also help you eat one less piece.

Please share with us the strategies and rules you use to upgrade your healthstyle!

This is the final post in the series How To Get Started Eating Healthy. Much thanks to those of you have shared your tips and insights in the comments so far. Summer Tomato will continue to build upon these ideas and help make it easier for you to upgrade your healthstyle.
