Delicious Nuts

“When I work out at the gym, I am there for a couple of hours and by the end of the first hour, I am still energized but start getting hungry. I read your article on packing food for lunch but wanted to specifically ask if you recommend any specific store bought bars.”

I frequently get questions about different nutrition and energy bars. Generally I think all of them are a bad idea, since they are little more than processed food with added vitamins and/or other trendy diet ingredients–a hallmark of food from the Matrix.

Energy and meal replacement bars serve only one purpose: convenience. So let’s make no mistake about it, these are not health foods.

But I understand that quick calories can be incredibly useful, particularly when intense workouts are a regular part of your day. If you get hungry and don’t have anything around to eat, the chances of you breaking down and eating something you’ll really regret increase substantially. But I think there are better things to carry around than energy bars.

My quick snack of choice is nuts or trail mix. I always have a small stash of nuts hidden somewhere in my gym bag (which comes with me everywhere). My personal favorites are almonds, pistachios, cashews and macadamia nuts. When I’m feeling ambitious I’ll combine a few different kinds together in a plastic zipper bag along with some dried fruit, just to mix things up.

One of the only drawbacks of snacking on nuts is if you are really hungry it is easy to eat too many and ruin your appetite for dinner. Too many nuts can also be difficult to digest. To avoid this I recommend getting into the habit of counting the nuts you eat, drinking water and waiting 20 minutes before eating more. The protein and fat in nuts can be very satisfying, but it takes awhile for the satiety signals to reach your brain.

For almonds, cashews and macadamia nuts 10 is a good number to start with. For shelled pistachios and peanuts, 15-20 nuts is more realistic. You are aiming for a single serving size of 1/4 cup. After some practice, eating the proper amount will come naturally to you. But at the beginning you should either count the nuts or measure them out in advance so it is easier to make good decisions.

There are a few other easily transportable foods that can serve as good substitutes for energy bars. Fruit is a great option, particularly filling fruits with lots of fiber like apples and oranges. Be careful with soft fruits, however, or you may end up with a gym bag filled with goo. Yes, I’m speaking from experience.

(Read: How to transport soft fruits and vegetables)

Another option that I don’t often use but am not opposed to is jerky. Beef and turkey jerky are generally high in protein and very satisfying. Just be careful about the teriyaki flavor that is often high in added sugar.

As a final thought, I wonder if you are maybe spending too much time in the gym? For weight loss and fat burning, more than an hour is really overkill and may actually work against you. If you are training for a specific athletic event, you’ve gotta do what you gotta do. But for the rest of us mortals one hour in the gym is more than enough to accomplish our goals. Maybe your hunger is a signal to you that it’s time to shower up and head home?

One of the most essential aspects of a great healthstyle is planning for moments of hunger throughout your day, but processed foods are hardly ever the answer, no matter how convenient.

Maybe you’re embarrassed. Maybe you’ve been too polite to ask me. Whatever the reason, know that you’re not alone.

The number of questions I get from people about bloating, gas and other digestive problems is not small, and since it is a sensitive subject I’m sure the questions I get represent just a fraction of those of you with concerns.

It’s not uncommon to experience digestive discomfort when you change your diet. For one thing, any drastic change in eating can be a shock to your system, even if it’s for the better. Also vegetables, legumes and other healthy foods contain a number of nutrients such as oligosaccharides, soluble fiber and natural sugars like fructose that can produce excess gas in the intestine.

Fortunately there are several things that can help prevent the embarrassment and discomfort that can be caused by eating these foods. However it is important to remember that everyone’s digestive environment is unique and different things will work for different people. This means you’ll need to experiment with the following tactics in order to identify what works best for you.

How To Prevent Gas and Digestive Problems

1. Chew thoroughly

When food reaches your intestine that has been only partially digested the bacteria in your gut cause the food to ferment, producing a substantial amount of (smelly) gas. More chewing helps your stomach acids do their job more effectively and can dramatically reduce the bacterial gas that gets formed.

Chewing is even more important when you’re eating vegetables and high-fiber foods, because they are more difficult to breakdown in your mouth and stomach than, say, a slice of Wonder Bread. This means you need to grow accustomed to chewing each bite of food more than you did for processed foods.

2. Take smaller bites

For the same reason it is important to chew, taking smaller bites can help ensure that large chunks of food do not reach your intestine undigested. People who take smaller bites also tend to eat slowly, which helps prevent overeating—another cause of poor digestion.

3. Don’t get too full

Overloading your stomach will eventually overload your gut, which can prevent proper digestion and cause discomfort. Both chewing and taking smaller bites can help with this, but there are many tricks you can use to eat less without noticing if this is a problem for you.

4. Eat balanced meals

On a similar note, you don’t want to overload your gut with one kind of food. If all you’re eating is a giant mound of vegetables for dinner and you’re having trouble digesting it, try balancing out your meal with more protein and fat. These will enable you to feel satisfied with a smaller volume of food (remember point #3), as well as decrease the load of any one nutrient that may be causing problems.

5. Increase vegetable and fiber intake gradually

Going from fast food every day to lots of vegetables can be shocking to your system. The bacterial environment in your gut is accustomed to a certain flow of nutrients, and drastically changing this can cause gas and bloating. Your gut can acclimate to a new diet over time, and the key to avoiding discomfort is to make changes gradually. If you’re really struggling with all that broccoli, cut back a little and see if it helps. Once you’re comfortable you can try adding more if you like.

6. Experiment with probiotics

Most of the gas in your intestine is produced by bacteria, but there are also strains of bacteria that have the opposite effect. Adding probiotic foods to your diet can help populate your gut with helpful bacteria that can ease digestion and reduce gas. There are several strains of probiotic bacteria, and research suggests that different strains work better for different people. Experiment with different kinds, and when you find one that works stick with it to maintain the benefits.

Examples of probiotic foods are yogurt, sauerkraut, kimchi, kombucha and miso. Keep in mind that when you cook these foods you will kill some of the active bacteria, so try to eat them raw whenever possible. I did an entire Summer Tomato Live episode on probiotics if you’d like to learn more.

7. Soak your beans

Beans are infamous for producing excess intestinal gas, but proper preparation can mitigate this problem. Instead of buying canned beans, get dry beans and soak them for at least six hours before cooking them. Soaking beans and discarding the soaking water eliminates the majority of the oligosaccharides that cannot be digested, reducing bacterial fermentation and intestinal gas.

8. Eliminate wheat

Some people have chronic stomach problems that are caused by food intolerance. Wheat sensitivities are the most common, and eliminating wheat and gluten is often the only solution. If you’ve tried everything and are still in pain, it may be worth giving up wheat and gluten for 4-6 weeks to see if it helps. If it works, now you know. If it doesn’t, at least you tried.

9. Eliminate dairy

Like gluten, many people have sensitivities to lactose, the sugar in milk, that can develop over time. Cutting it out for a few weeks is an easy way to tell if it is a problem for you.

10. Avoid fake sugars

Sugar alcohols such as sorbitol and xylitol can cause digestive problems similar to the oligosaccharides found in beans. If you’ve been relying on artificial sweeteners to cut back on real sugar, this may be a cause of your digestive issues.

11. Reduce fresh and dried fruit intake

Fructose can ferment in the gut, and too much will result in gas and discomfort. If you’ve drastically increased your fruit intake, this may be problematic for your digestion. Cut back until you find the amount you can tolerate.

(Note: I’m giving you the benefit of the doubt and assuming you’ve eliminated most of the high-fructose corn syrup from your diet already).

12. Use medication

Beano is an enzyme formulation that helps with digestion of oligosaccharides that can cause gas. If you simply cannot miss out on your grandpa’s famous chili, popping the occasional Beano at the beginning of your meal should help.

On the other hand, if you still haven’t figured out what you’re sensitive to and find yourself in an unpleasant state, Gas-X is an effective form of relief that can be used on occasion. It takes 20-30 minutes to work. As always, be sure to follow the safety instructions when taking any medication.

Most people know instinctively to avoid bruised or blemished produce, but there is much more involved in the art of choosing fruits and vegetables.

While buying fresh food is always a little bit of a craps shoot (and not every rule will apply to every piece of produce), these tips will give you the basic skills you need to hold your own at the farmers market.

What To Look For When Picking Produce

1. Bright color

After you’ve checked for bruises, blemishes and pests (harder to see on vegetables like cauliflower and cabbage, so double check), look for fruits and vegetables with the brightest, most inviting colors. The tastiest, vine-ripened produce should be vibrant, with its skin entirely saturated with color. If the item has a dull color or whitish sheen that means it is either not fully ripe or was deprived of sun or nutrients.

For fruits like cherries look for stems that are green instead of brown, since these fruits will be fresher.

2. Heavy weight

Generally you want to pick produce that is the heaviest relative to the rest of your options. Light weight produce is more likely to be dry and mealy, but heavier produce will be juicy and crisp.

The best way to tell is to pick up two similarly sized fruits, one with each hand. After you’ve tried a few it will be obvious that certain fruits are much heavier than the rest, and those are your best bets. This applies to both fruits and vegetables, but mostly to fruits.

3. Firm, but not hard

Because the best produce is moist and juicy (see point #2), it should also be perfectly plump. This means that it will be firm to the touch—think crisp and succulent—but not hard, squishy or limp.

While the perfect amount of firmness will vary for each type of produce, comparing within the batch can be very informative. For soft fruits, gently picking a piece up should tell you if it’s too soft or hard.

For vegetables with stalks like carrots and broccoli, be sure the ends don’t give too much when you try to bend them (but don’t try too hard or they might snap).

While this tip works as a general rule, keep in mind that it doesn’t apply to everything. Figs, for example, are better very soft, as are certain kinds of persimmons.

4. Fragrant aroma

Probably the most telling test of the quality of your fuit is how it smells. Unripe fruits smell like nothing, or at best the cardboard it was packed in. But ripe produce almost always smells faintly (and often overwhelmingly) of how it is supposed to taste.

Hold the part of the fruit that was attached to the stem close to your nose and breathe deeply. Compare a few of your options. The strongest smelling fruit will be the most ripe and ready to eat immediately. If you’d like your fruit to last for a few days, it is best to go with a piece that still smells good, but has a less overwhelming scent.

It’s also worth smelling your vegetables, though this tip does not apply to them all (eggplant is a notable exception). Green leafy vegetables and herbs are particularly fragrant. But even carrots, artichokes and squash can have a distinctive smell. Peppers are my personal favorite.

What are your tips for picking perfect produce?

Yogurt, muesli and blueberries

I should admit right now that I’m a born again breakfast eater. In the past I always told myself that skipping breakfast meant one less meal adding calories to my day, and I was proud to have eliminated this annoyance from my life.

For the last several years, however, I have grown to love breakfast and am something of an evangelist. Breakfast may seem like an odd thing to try to covert people to, but once you see my reasons you may become a believer yourself.

8 Reasons Breakfast Makes Your Life Better

• It’s easy. Breakfast doesn’t take much time or energy to prepare; I’m half asleep when I pour my cereal, rinse my fruit and boil my coffee every day. It also requires minimal planning. Just buy everything you need every week or two and you are good to go. What’s your excuse?
• Health wins. We all must deal with the internal struggle between eating healthy and eating not-so-healthy. Throughout the day breakfast is by far the easiest battle in which health can triumph, since there is no outside social pressure and unhealthy options are harder to attain. I recommend taking winning odds whenever they are presented.
• Hunger check. If you eat a satisfying breakfast before heading into work you are less likely to be tempted by the junk food that haunts most office environments. Likewise, you will have better self-control when it comes time to decide what to eat for lunch.
• Whole grains. For my own healthstyle, intact whole grains are the most difficult to get in my diet. Unsweetened oats, plain brown rice and quinoa aren’t exactly staples on American restaurant menus. But without grains I feel constantly hungry and my workouts suffer. If I eat them at breakfast I am guaranteed at least that one serving during the day. (For tips to get more whole grains at dinner, check out my easy frozen brown rice balls).
• Higher metabolism. Eating healthy food has a positive effect on your metabolism. Not only does what you eat for breakfast affect how your body reacts to different foods for the rest of the day, it also influences your metabolic rate in the long term. Be careful though, highly processed and easily digested foods have a negative effect.
• Healthy habits. Healthy behavior begets more healthy behavior. According to some studies, this is especially true of breakfast eaters. Waking up and eating a healthy breakfast encourages you to pack a healthy lunch and plan your day around wholesome food. It feels really good to do healthy things, but we easily forget this when presented with free donuts on an empty stomach during a mid-morning meeting. Build your healthy habits when it is easy and help them stick around for the long haul.
• Self-esteem. I think it is important to reiterate how good it feels to do healthy things for your body, and as a bonus it extends to how we feel about ourselves. Most of us feel proud and confident when we know we are doing the right thing. Why not start out each morning on the right foot?
• Deliciousness. Of all the reasons I just listed, this one probably has the biggest sway with me personally. My breakfasts are absolutely delicious and I adore waking up and eating such yummy food. It is worth going out of your way to find healthy foods you enjoy eating, that way good food has as much pull on you as the less healthy junk. This will make your food decision making a whole lot easier.

Once you have convinced yourself that eating breakfast is important and worthwhile, it helps to know what constitutes a healthy one. I have written about breakfast before, focusing on the difference between fake “whole grains” as sold to us by processed food manufacturers and real intact whole grains.

Recently I have switched to a new favorite breakfast: plain yogurt, muesli and fruit.

I love this new combo for a few reasons

1. I tried yogurt because I was having digestive issues for a few weeks and was hoping the probiotics in the yogurt (I eat even more probiotic foods now) might help. It totally did, and I’m sold on this method for improved digestion (despite my mild lactose intolerance).
2. Coarse and chewy muesli is perfect on yogurt and I was able to completely cut out the fake whole grain flakes that bothered me about my old breakfast. Woohoo!
3. The added protein and fat from the lowfat plain yogurt helps me feel satisfied longer in the day and adds a creamy luxury to my morning.

Be sure that when you are choosing your healthy breakfast you find foods with no added sugar. For example, fruit and vanilla yogurts are notorious for having obscene amounts of sugar (especially vanilla) putting it more on par with ice cream than health food. Likewise, most store bought granolas are loaded with sugar, molasses, honey, agave, concentrated fruit juice and other sweeteners. This is why I prefer muesli–completely unsweetened grains with bits of dried fruits, nuts and seeds.

When choosing plain yogurt I recommend lowfat instead of nonfat yogurt, because it is much more palatable and satisfying. Nonfat plain yogurt tends to be too tangy for me. Also, you need the fat to help with nutrient absorption and satiation.

My breakfast

• 1 c. Plain lowfat yogurt
• 1/4 c. Dorset muesli
• 1/4 c. fresh fruit

What is your favorite healthy breakfast?

10 Foods You Didn’t Know Were Damaging Your Teeth

by Robert Milton

Most people know candy and other sugary foods wreak havoc on their teeth, but how about fruit?

You’ve probably heard brushing and flossing twice a day is the best way to keep your teeth healthy. But some foods cause enough damage to warrant extra cleanings.

How does food damage your teeth?

There are two main elements of food that tarnish your pearly whites: sugar and acid.

Sugars, especially sucrose (table sugar), feed the millions of bacteria already in your mouth. Bacteria feast on your plaque buildup and produce lactic acid, which erodes your tooth enamel. Sucrose is the worst form of sugar because it adheres to teeth very strongly making it (and the bacteria) difficult to remove even when brushing.

Acids naturally occur in many foods, including fruit. In these cases, bacteria aren’t necessary to produce acid and cause tooth decay. Instead, acidic foods eat away at your enamel and break down your teeth directly.

Generally you can wash away natural acids by drinking water. Ironically, brushing soon after consuming acidic foods or beverages can actually cause more damage. Because teeth are porous, brushing softens them and makes them more susceptible to acid. After eating acidic foods, you should wait at least an hour before brushing.

What foods should you worry about?

In addition to the sugar and acid in foods, you should consider the length of time food is left on your teeth. The more time bacteria have to produce acids, the more damage will be done.

While many of these foods are healthy for other reasons, you should try and care for your teeth soon after eating them. Drinking water with your meal, chewing sugar-less gum, rinsing with an alcohol-free fluoride mouthwash or flossing and brushing with toothpaste reduces the risk of damage.

Look out for:

• Sugar and/or acid content
• Stickiness (how much food remains on teeth)
• How long the food is in your mouth

10 Foods That Damage Your Teeth

1. Apples

Apples are high in acid, are surprisingly hard on your enamel. While a daily apple may keep the doctor away, the acid might keep your dentist on speed dial. Eating apples is fine, just be sure to rinse your mouth with water or mouthwash shortly after.

2. Hard candies

Though you probably know the sugar in candy is a problem, hard candies are especially harmful because we tend to hold them in our mouths longer. Also be aware that cough drops are often made with sugar, so opt for the sugar-free brand if available.

3. Pickled vegetables

Pickles are made with vinegar, which is acidic, and often sugar as well. While the vegetables are healthy, the brine is can damage your teeth. Drinking water with your meal helps wash away acids and sugar, but remember to brush an hour later.

4. Bread

Many breads contain sugar—especially processed white breads. It’s best to check the labels for any added sweeteners that will breed mouth bacteria. Bread is also sticky and gets between and behind your teeth.

5. Popcorn

Popcorn is notorious for getting stuck in your teeth, and the areas between your teeth will cultivate more bacteria for that reason. It’s okay to treat yourself to a bag of popcorn as long as you rinse with water and remember to floss and brush after.

6. Peanut butter

Sticky and often made with sugar, peanut butter not only feeds bacteria but makes it easier for them to adhere to teeth. Look for natural peanut butters with no added sugars to lessen the problem.

7. Jelly

Along with peanut butter, jelly or jam is loaded with sugar and quite sticky. Even the all-fruit brands contain natural sugars and encourage plaque and bacteria if not washed away soon.

8. Meat

Meat tends to get stuck between your teeth, and some meat products contain sugar as a preservative. While the amount may not be very high, any food that sits between your teeth can promote tooth decay. Try chewing sugar-less gum after eating if you can’t brush right away.

9. Diet soda

Just because it doesn’t have sugar doesn’t mean your teeth are safe. The acidity of diet sodas is still extremely high, making it one of the worst products for your teeth.

10. Salad dressing

More of a condiment than a food, salad dressings use vinegar and sugar for flavor. Salads should be a staple in anyone’s diet, but be careful of the dressings that can harm your smile.

What are your tips to reduce tooth decay?

We all know the story. Eating carbohydrates causes a spike in blood sugar, which results in a surge of insulin. Insulin shuttles all that extra sugar into your fat cells and you become obese. Over time, your poor helpless organs become resistant to insulin and you develop type 2 diabetes, heart disease and high blood pressure, thereby shortening your life by 7 years.

All of that is true.

The story is more complicated, however, because all carbs are not created equal.

I’m not here to tell you sugar and flour won’t make you fat, they will. But unrefined foods that just happen to be slightly higher in starch or sugar don’t, in reasonable quantities, elicit giant blood sugar spikes or abnormally high insulin levels.

Instead, unprocessed carbohydrates generate gentle, moderate rises in your blood glucose and insulin, giving you a small but long-lasting supply of energy your muscles can use for several hours. This is what is supposed to happen when you eat nourishing food, and normal healthy people have no reason to fear it.

(In my experience, eating intact grains can even curb sugar cravings and help you avoid those late night slip ups that undo all your progress and riddle you with guilt.)

So what are these magical carbs that don’t make you fat? Pretty much anything you can find in nature. If it comes in a box and has a prominent “whole grain” sticker on it, you’re barking up the wrong tree.

Don’t get me wrong, this is not a license to gorge yourself on grains or any food. Eat enough of something, or eat it quickly, and you’ll still end up with more sugar in your blood than your body knows what to do with. But in moderate quantities you can eat from the following list without risking your life or growing out of your favorite jeans.

10 Tasty Carbs That Won’t Make You Fat

1. Fruit

Popular diets like Slow-Carb recommend limiting fruit, mainly because it makes “rapid fat loss” a little less rapid. However you can continue to lose weight even while eating fruit, so long as you don’t pig out on it. Fructose, the sugar in fruit, is bad for you not because it raises your blood sugar, but because it is converted to fat in the liver. However the relatively small amounts of fructose present in whole fruit is nothing to worry about.

2. Beans

Though beans are relatively rich in carbs, a substantial portion of it is fiber and the overall glycemic load is pretty low. Beans are also an excellent source of iron, protein and folate, as well as essential minerals.

3. Oats

Oatmeal is tricky because Quaker and other companies have somehow convinced us that cooking real oats is too hard and time consuming for any civilized human being. This conveniently allows them to mark up the prices on their instant, pre-sweetened varieties that are closer to dessert than they are to a healthy breakfast. But in reality real rolled oats are low calorie, high fiber, and not fattening in the least. They also cook up in minutes.

4. Dairy

Have you ever checked the label of plain yogurt and wondered how all that sugar got in there? No you’re not crazy, it’s just that the FDA nutrition labels don’t distinguish between added sugar (sucrose or fructose) and naturally occurring sugars like lactose, the sugar in milk. In reasonable quantities and without added sugars (read labels carefully), unsweetened dairy products will not usually contribute to fat accumulation.

5. Lentils

Like beans, lentils are full of fiber and slowly digesting. If anything, adding lentils to your diet will likely help you lose weight, not make you gain it.

6. Farro

One of my favorite foods, farro is a dense and chewy grain with a thick husk and rich flavor. Although it is a grain, farro is very filling and a little goes a long way. No need to spike your blood sugar with this stuff.

7. Wine

Though people often cite wine and alcohol as having a lot of calories, your body digests alcohol calories different than sugar calories and they have virtually no impact on glycemic response. Though there are many reasons to keep your wine portions under control, sharing the occasional bottle won’t stop you from losing weight.

8. Quinoa

Technically a seed and not a grain, quinoa (keen-wah) is high in protein and fiber, and has a very low glycemic index. It’s also high in iron, has a complete amino acid profile (great for vegetarians) and cooks in almost no time.

9. Brown rice

A lot of people claim to dislike brown rice, but cooked properly it can be a beautiful addition to almost any meal. A small serving of brown rice can make your salads, stir fries and other vegetable dishes more satisfying, while not forcing that big blood sugar spike you’d get from eating bread.

10. Potatoes

This may surprise you, but moderate amounts of potatoes cooked in healthy oils (not processed vegetable oils) won’t make you fat. Potatoes are actually fairly high in iron, vitamin C, vitamin B6 and minerals, making them a healthy alternative to other starches so long as you don’t go nuts.

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?

Heirloom Tomatoes

A harsh reality hit me this past Saturday. Believe it or not, I was woefully unprepared to bring everything I wanted home from the farmers market.

It wasn’t obvious to me at first. After all I had remembered to stop at the ATM for cash, brought with me my large market bag, and even had my trusty roll of plastic bio-bags to collect all the delicious summer greens (plastic is so 2008).

This was not a rookie farmers market mistake I made, this was more of a seasonal oversight. Dedicated farmers market shoppers (particularly fruit lovers) have a special concern in the summer that does not exist in the winter: soft produce.

Nothing is sadder than arriving home from the farmers market and finding your bags full of mashed plums and tomato sauce. If you purchase a decent amount of produce you are almost certain to have some fruit casualties if you rely on only one large market bag, even if you’re careful to place them at the top. The tender skins of summer fruit are simply too delicate to withstand any pressure, whether it’s from weight, neighboring produce or the sides of your market bag.

Losing produce is even more heartbreaking when you realize that those stone fruits and heirloom tomatoes could have easily cost upwards of $3.50 per pound.

Luckily there are ways to avoid this tragedy. I recommend a two tiered approach. First, bring a few stackable tupper containers. You want them to be big enough that they allow two or three fruits to fit comfortably inside without pressure from the lid, and without the fruits pressing too firmly against each other.

On the other hand, you don’t want the fruits rolling around inside the tupper. You can avoid this if you place the fruits inside the tupper while they are still inside their paper or plastic bag. Be particularly careful if any of the fruit or tomatoes you purchase have protruding stems, since these can puncture and ruin neighboring fruits.

It is also useful to bring a second, smaller market bag so you can keep your delicate produce completely separate from your heavier purchases. This will save you from worrying about what goes where in your bag and you can focus all your energy on finding the best produce.

Glance through this checklist next time you head out to your local summer market to be sure you have everything you need.

Summertime Farmers Market Checklist

1. Cash

Don’t count on vendors taking credit cards or there being an ATM nearby.

2. 2 Large farmers market bags

One bag to carry the heavy stuff, and another (it can be smaller) for your delicate fruits and tupper.

3. 2-3 Medium-sized tupper containers

Look for wider, flatter containers that can keep peaches and plums in a single layer, stems facing down.

4. Small biodegradable or green bags for produce

These are to carry loose greens and other produce.

5. Sunglasses

It’s summer, and bright out!

6. Camera

Farmers market produce is inspiring and the market changes every week. If you’re anything like me, you’ll want to capture the beauty.
