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.

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.

How do you get your soft produce home safe from the farmers market?

White Nectarines

Dear Readers,

I know that many of you enjoy the farmers market and visit it regularly, and if this describes you I’m sure you already know what I’m about to write.

For those of you who like the farmers market but find yourself cooking up excuses each week not to go, it is time to talk yourself out of that habit. At least this once. If you’re ever going to make visiting your farmers market a priority, now is the time. This is the season when a taste of a simple plum can change your life (I got mine from Paradez Farms).

Heirloom Tomatoes

Pluot Slices

There are only a few weeks of the year when berries and stone fruits haunt the market simultaneously, when you can get sweet cherries and perfect peaches. Even the tomatoes now would never be mistaken for anything other than a fruit. At this time of year it is possible to win friends with salad (I’ve done it many times already).

Summer Squash

Green Chard

Today I saw children begging their parents to buy foods that most of us grew up hating (beets!). And I even bought a bag of broccoli simply because it was so cute. That’s right, even vegetables are getting their moment in the sun.

Adorable Broccoli

Summer Beets

(the garlic and onions are photogenic??)

Summer Onions

Purple Garlic

An added bonus is the late summer produce is just beginning to arrive as well. Today I bought my first corn, and saw eggplants available at a few different stands.

Bodacious Yellow Corn

Mission and adriatic figs are also available, and surprisingly sweet for this early in the season. I even spied a few melons hanging out today, though I was too busy cradling peaches and nectarines to get one home safely.

First Eggplants

And for today’s Moment of Zen, I present: kohlrabi.

Enjoy the summer! And if you discover or learn to love anything new this year, please come tell us about it.

For The Love of Food

Welcome to Friday’s For The Love of Food, Summer Tomato’s weekly link roundup.

Lots of interesting health and nutrition stories this week. I particularly love the piece about how exercise impacts cognitive performance, and the bits about the health benefits of grains. I’m not in the mood to focus on any BS this week, but if I did it would have certainly been the Monsanto court decision.

I read many more wonderful articles than I post here each week.
