Modified Fasting: a good weight control strategy?

Mpj042253000001 People fast for many reasons: as a religious observance or spiritual ritual, as a political protest, in preparation for medical procedures, or as an occasional health practice.   And studies have confirmed that short-term fasting can have a number of health benefits.

Yet fasting for the purposes of losing weight is not generally seen as a good idea.

One argument is that you need to learn healthy eating habits in order to achieve long-term weight control. Fasting is by necessity a short-term strategy. Sooner or later, you have to begin eating again. And skills such as exercising portion control, choosing more nutritious foods and fewer empty calories, eating more vegetables and whole grains are not developed by fasting.

And we’ve all heard the argument that people who skip meals (whether one or a whole day’s worth) tend to eat more calories later to compensate. (More on that in a moment)

But a series of new studies, summarized in the U.S. News and World Report, suggest that there may be a legitimate role for modified fasting as a weight loss tool. Continue reading “Modified Fasting: a good weight control strategy?” >

Living Well to 100

What would it take to live to 100—in good health? An international consortium of researchers recently gathered at Tufts University in Boston to debate the answer. This meeting brought together heavy-hitters from every corner of medical research—cardiovascular medicine, endocrinology, nutrition, obesity management, experimental genetics, sleep research, and more.

After two days of research presentations on every aspect of the aging process, the panelists were asked to consider:

What are the top five things we should do if we want to live well to 100?

You might be surprised at the answers. It’s not about expensive medical interventions, drugs, or futuristic technology. According to the best available research, it all comes down to a few simple habits—things we all can do.

On today’s menu: weeds

Part of the fun of a CSA-share is the opportunity to try vegetables that would otherwise never end up in my shopping cart, such as the sweet potato leaves I wrote about a couple of weeks ago.  One of our options this week was purslane, a plant related to the portulacas you might plant in your garden.  I first read about purslane in Artemis Simopoulos’s book The Omega Diet.  Purslane is one of the richest vegetable sources of omega-3 fatty acids.

A big part of the reason that the meat from pasture-raised cattle (and wild game) is higher in omega-3 fats is because grazing animals favor these succulent wild greens and will eat them preferentially over other grasses.  It makes good grazing for people, too. According to research published in the Journal of the American College of Nutrition, 100 grams of purslane contains 300-400 mg of omega-3 fats (alpha-linolenic acid), along with over half a day’s supply of vitamin E, a third of the day’s vitamin C, and a quarter of the day’s vitamin A.  But does it taste good?

I’d never bought or cooked with purslane before. In fact, I’d never even seen it at the grocery store. But in her weekly email to us One Straw Farm shareholders, our farmer Cheryl Wade gave it a big drumroll:

“The tips, either in or out of flower are cute enough for garnish and add a definite zip to fresh salads. You can also steam it, stems and all and serve it with oil and vinegar or butter and soy sauce or most people need nothing on it at all. When you have a bumper crop you can start steaming piles of Purslane and popping it in the freezer as a blessed addition to soups. It does a nice job of thickening the soup, too. Purslane can be substituted for spinach or wild greens in lasagnas, filled pastas, and Greek-style tarts.”

I couldn’t wait.  When I got to the market on Thursday, however, I opted out of the purslane and chose other vegetables instead. Why? Because once I saw it, I realized that I’ve got all the purslane I need growing in my garden! I bet you do, too. It sprouts up everywhere, in between the cracks in the terrace, along the sidewalk, and in flower and vegetable beds. In fact, I spend a good part of the summer weeding it!  Here’s what purslane looks like:

Purslane

As it happens, my personal crop was a little depleted by some power weeding we did over the weekend, but experience tells me it will be back soon. So instead of weeding the next batch, I plan to harvest it and try some of Cheryl’s suggested preparations. I’ll let you know how it goes. If you haven’t weeded your garden recently (and haven’t sprayed any chemicals on it), you might enjoy some purslane today. Here’s a couple of other serving suggestions from The Omega Diet (p. 157):

“When you first try purslane, serve it raw tossed with olive oil, lemon juice, salt, and pepper. Delicious. Once you’ve gained appreciation for its delicate flavor and unique texture (like a cross between tender pea pods and a buttery lettuce), add it to mesclun, toss it in soups, or saute briefly in butter and serve with a light cream sauce.”

Adventures with vegetables

Sweet potato leaves: who knew they were so delicious (and good for you)?!

Sweet_potato_leaves

As part of our commitment to eat more local foods, (see my post “Six ways to make your diet healthier (for the planet)”), we joined a CSA this year.  Back in March, we paid a lump sum  to a local organic farmer in exchange for a share of this year’s crops.  Now that the growing season is underway, we get a  basket every week, full of whatever vegetables they’re harvesting that week.

It’s been a fun challenge to get through the weekly mound of fresh greens, lettuces, beets, and squash before the next one arrives.  This week’s basket included a vegetable I’d never had before: sweet potato greens, presumably plucked from the crown of sweet potatoes that we’ll be enjoying later this season.

Like most greens, sweet potato leaves are  very low in calories. Plus, they’re an excellent source of vitamin K. (You can read more about this little-known nutrient in this post on  Vitamin K and blood thinners.)

The farmer suggested sauteeing them in a bit of oil, salt and pepper (what doesn’t taste good that way?!).  So this morning I did just that and folded the lightly wilted greens into an omelet with a bit of Boursin cheese.  DELICIOUS!  Turns out that sweet potato greens are tender and mild –not at all bitter–and without that “chalky” feeling that spinach can leave on your teeth.  Check your local farmer’s market this weekend for this delectable treat!

Will Taking Vitamins Improve Your Health?

It’s a hotly debated question among health researchers. New studies come out every year but we don’t seem to be getting any closer to a definitive answer. About half the studies show that people who take vitamins are healthier and the other half find that taking vitamins makes no difference…or, in a few cases, actually make things worse. I have to admit that I’ve held, at various times in my career, different views on the question.

(See also this Nutrition Diva podcast episode on Multivitamins.)

We know that the nutrients in food play important roles in keeping us healthy. Calcium helps prevent osteoporosis, folic acid helps prevent neural tube defects, antioxidants repair cellular damage, and so on down an ever expanding list of nutrients and co-factors. It seems like supplementing an (imperfect) diet with additional nutrients is a reasonable way to make sure we’ve got our bases covered.

If we’re talking about a 25¢ one-a-day multivitamin, I guess the vitamin as insurance policy makes sense. But it’s gotten way more complicated than that. For one thing, the list of “basic” nutrients gets longer and longer. A multivitamin used to involve 15 or so nutrients (A, B, C, D, E, and a few minerals.) Now, a typical multi boasts several dozen compounds, from astaxanthan to vanadium. But it’s still not truly complete. Next to it on the shelf you’ll find the anti-oxidant booster, the bone health formula, the immune booster, plus the the formulas for your eyes, skin, nails, hair, memory, joints, and prostate. Before you know it, you’re forking out a couple hundred bucks and month and swallowing a fistful of vitamins every day. But are you getting your money’s worth?

Tasty Ways to Get Your Vegetables

It’s not just kids who resist eating vegetables. The latest reports show that less than one-third of American adults are eating the recommended five servings fruits and vegetables every day.

Believe me, I know how this happens. Even as a professional nutritionist, I have sometimes struggled to follow my own advice! I’d load up my fridge with fresh produce with the best of intentions. But something always got in the way of actually eating them. I just never seemed to have time to make a salad for lunch. Then, we’d end up eating out for dinner while that day’s vegetables wilted in the fridge. On busy days, dinner is often the only meal that includes any vegetables at all, and how many servings of steamed broccoli can you eat at one meal?

But recently, I’ve discovered a couple of really simple strategies that have literally tripled the amount of fresh vegetables we eat every day. And I’m not talking about adding grated carrots to your oatmeal or switching from gin-and-tonics to Bloody Marys. Here’s what’s worked for us: Continue reading “Tasty Ways to Get Your Vegetables” >
