It’s a pretty good bet that if you ate three pomegranates a day, you’d lose weight and live longer.For one thing, given how finicky and labor-intensive it is to eat a pomegranate, you wouldn’t have much time left to eat other foods.

Then there’s the growing body of research suggesting that the polyphenolic antioxidants found in pomegranates (and in red grapes, blueberries, cranberries) have beneficial health effects that include improving cardiac health and reducing the risk of cancer.

I’ve talked about some of those benefits before, and frequently drink pomegranate juice myself. But the article points out that the juice may not offer the same benefits in terms of weight control.

Check the nutrition labels, and you’ll see why. These are sugar bombs of the first order.

An 8-ounce serving of Pom? Thirty-four grams of sugar. Whole Foods’ 365 Everyday Value: 40 grams. Frutzzo: 32 grams.

By comparison, an 8-ounce serving of Coca-Cola contains 27 grams of sugar; 8 ounces of Mountain Dew, 31 grams.

More sugar than soda? Wow. I guess all that sugar is in the fruit as well, but as the article points out it is a little harder to get at. Another one of those cases where slowing down the pace of eating can have benefits of its own.

Avocado Nutrition » iFitandHealthy.com

As we grow increasingly health-conscious in our diets, avocado has stepped up to the plate as a choice replacement for fatty meats. Think ALT, hold the bacon. Think of all the veggie wraps teasing you away from those roast beef sandwiches.The small irony here is that avocado is one fat fruit. A typical, medium-sized variety provides 25 percent of your daily intake, if you eat the whole thing. Most of this is monounsaturated fat — the good kind — with no cholesterol and no sodium.

A little fat in the diet is necessary, and the good kind is a good way to get it. Avocado provides great texture and flavor to vegetarian dishes.

BBC NEWS | Health | Organic food ‘better’ for heart

Organic fruit and vegetables may be better for you than conventionally grown crops, US research suggests.A ten-year study comparing organic tomatoes with standard produce found almost double the level of flavonoids - a type of antioxidant.

Flavonoids have been shown to reduce high blood pressure, lowering the risk of heart disease and stroke.

I have found that many organic products seem to taste better. Some would argue that I am imagining the difference, but so what? In my mind, the better taste justifies the added cost.

To me it only makes sense that I should be minimizing my intake of fertilizers and pesticides. I don’t need much other justification, though I am not surprised to find them.

When a recent study showed no special weight loss benefit from low-glycemic diets relative to other diets, I said:

I’ve always been a believer in the “weight gain/loss = calories in - calories out” theory. Still, the concept of glycemic load has some intuitive appeal. For example, given the link between obesity and diabetes, and the need to control sugar absorption in the latter case, perhaps overweight people should pay attention to glycemic index even if they aren’t trying to lose weight.

As it turns out, not only was I on the right track with that question but other researchers were in the process of answering it.

Insidermedicine Video News : Low Glycemic Diet Lowers Cholesterol, Good for Weight Loss

Dieters who select a low-glycemic load diet my have more success at losing weight, than those following a low carbohydrate or low fat diet, say researchers in a report published in the Journal of the American Medical Association.Three popular diets have recently received much attention – low fat, low carbohydrate, and low glycemic load. However, there is still no consensus on which diet yields the best results. Glycemic load refers to the increase in blood sugar that occurs following the consumption of a carbohydrate. Foods low on the glycemic index, such as certain fruits, nuts, and vegetables, release glucose gradually into the blood stream. Foods high on the glycemic index, such as breads and pasta, provoke an immediate response in the blood sugar levels and tend to result in increased hunger and overeating.

For people with tendency for high insulin levels 30 minutes after eating, the low-glycemic diet produced a five times greater decrease in weight than the low-fat diet at 18 months. The low-glycemic diet was also more effective in reducing body fat and improving cholesterol and trigyceride levels, while the low-fat diet improved low-density lipoprotein, or “bad” cholesterol.

Differences in insulin secretion among individuals may help predict the success of weight loss programs, and reducing glycemic load may be especially important for those who secrete insulin at a higher level.

Makes sense to me.

ScienceDaily: Pistachios May Calm Acute Stress Reaction

Eating pistachios may reduce your body’s response to the stresses of everyday life, according to a Penn State study.
“A ten-year follow-up study of young men showed that those who had larger cardiovascular responses to stress in the lab, were more likely to contract hypertension later in life,” says Dr. Sheila G. West, associate professor of biobehavioral health. “Elevated reactions to stressors are partly genetic, but can be changed by diet and exercise. Lifestyle changes can make the biological reactions to stress smaller.”

West and her colleagues investigated the effects of pistachios on standardized stressors on subjects who had high cholesterol, but normal blood pressure.
The researchers found that both pistachio containing diets reduced the stress effects on blood pressure, but that the 1.5 ounce pistachio diet reduced systolic blood pressure by 4.8 millimeters of mercury while the 3-ounce pistachio diet only reduced systolic blood pressure by 2.4 millimeters of mercury. The diets had no effect on normal, resting blood pressure.”When we only look at blood pressure, these results are confusing,” says West. “If it is the pistachios, why is it not dose related?”

When the researchers looked at total peripheral vascular resistance, it was clear that the 3-ounce diet caused greater relaxation of arteries.

Those Penn State researchers sure do like pistachios. Then again, so do I.

ScienceDaily: Tart Cherries Can Alter Factors Linked To Heart Disease And Diabetes, Animal Study Suggests

Tart cherries may be good for more than just making pie, according to new data from an animal study conducted by University of Michigan Health System researchers and presented recently at a major scientific meeting.

In a study involving rats, the researchers report that animals that received powdered tart cherries in their diet had lower total cholesterol, lower blood sugar, less fat storage in the liver, lower oxidative stress and increased production of a molecule that helps the body handle fat and sugar, compared with rats that didn’t receive cherries as part of an otherwise similar diet. All of the rats had a predisposition toward high cholesterol and pre-diabetes, but not obesity.

I have been getting some very tart freeze-dried cherries for my megamuffins recently. Wonder if they work?

Pomegranate Juice May Be Good For The Prostate And Heart, Reports The Harvard Men’s Health Watch

Two recent studies suggest that pomegranate juice may help fight prostate cancer. In one study, scientists grew cells from highly aggressive cases of human prostate cancer in tissue cultures. Pomegranate fruit extracts slowed the growth of the cultured cancer cells and promoted cell death. The researchers then implanted the cancer cells in mice. A group of mice that received water laced with pomegranate juice developed significantly smaller tumors than the untreated animals. In a preliminary study of men with prostate cancer, pomegranate juice lengthened patients’ PSA doubling time (the longer the doubling time, the slower the tumor is growing) from 15 months before treatment to 54 months on the juice.Preliminary results in test tubes, animals, and humans suggest that pomegranates may also have beneficial effects on cardiovascular disease. Studies show that pomegranate juice can protect LDL (bad) cholesterol from oxidative damage. The juice has also been shown to slow the progression of plaques in mice with atherosclerosis. Results from two small clinical studies are even more intriguing, showing that carotid artery thickness decreased and cardiac blood flow improved in pomegranate juice drinkers. However, preliminary research also suggests that pomegranate juice may interact with certain medications, much like grapefruit juice does.

I have been alternating between pomegranate and grapefruit juice with breakfast.

Aspirin May Help You Live Longer

A study found women who took aspirin regularly had a 25% lower risk of death from all causes, not just heart problems. The new findings actually contradict prior research, so experts say women should not take aspirin without talking to their doctor first.

Don’t you just love contradictory studies? At least you shouldn’t have to worry if you’re taking aspirin for the occasional headache.

Dark Chocolate May Lower Risk Of Cardiovascular Disease

If you eat some dark chocolate now-and-again you could well be lowering your chances of developing cardiovascular disease, say researchers at Yale Prevention Research Center, Connecticut, USA. It seems dark chocolate contains flavonoids which boost the function of endothelial cells in the lining of blood vessels.

The study showed improvement in a fairly short time, though with high intake of chocolate - 8 oz per day. No sugar outperformed sugary chocolate, but both beat a placebo.

For those who thought eating more of anything would somehow lead to lower weight, you will be disappointed with this headline.

Eating extra soy may not promote weight loss | Science & Health | Reuters

Adding soy-protein-rich foods while cutting calories doesn’t accelerate weight loss, a new study shows.Overweight women who ate 500 fewer calories a day than normal while consuming an extra 18 grams of soy-rich food daily for 12 weeks didn’t lose any more weight than their peers who didn’t add the extra soy, Dr. Marie-Pierre St. Onge of St. Luke’s/Roosevelt Hospital in New York City and colleagues found.

You see, it is calories in versus calories out, more than the composition of those calories, that results in weight gain or loss. Still, the higher-soy diet (with equal calories) did lower insulin and bad cholesterol. And those are good things to lower.
