    How resveratrol (in grapes, peanuts and wine) fights fat and disease

    Resveratrol, a constituent of grapes, peanuts and certain other plants, can fight the proliferation of fat cells and improve the uptake of sugar from the blood, a pair of new studies show. Their findings suggest mechanisms to explain why grape products, including wine, have developed a reputation as heart healthy, obesity-fighting and beneficial for people developing diabetes.

    Walnuts slow prostate cancer growth

    SAN FRANCISCO A new study suggests that mice with prostate tumors should say “nuts to cancer.” Paul Davis of the University of California, Davis, hopes follow-up data by his team and others will one day justify men saying the same.

    For years, this nutritionist had been studying heart benefits of walnuts. Most nuts – in sensible quantities – can benefit the heart. But among...

    Caffeine Aids Golden Girls' Mental Health

    Although wine may improve with age, the human body tends to falter during the so-called golden years. Among the most exasperating declines occur in memory and critical aspects of reasoning. However, downing plenty of caffeine-rich coffee—or tea—may offer one low-cost solution for keeping aging wits sharp, a French study finds. The rub: This strategy appears to benefit only women.

    Counterintuitive Toxicity

    For decades, researchers largely assumed that a poison's effects increase as the dose rises and diminish as it falls. However, scientists are increasingly documenting unexpected effects—sometimes disproportionately adverse, sometimes beneficial—at extremely low doses of radiation and toxic chemicals.

    Consider the environmentally ubiquitous plastic-softening agent, di-2-ethylhexyl...

    Trans Fats Are Bad, Aren't They?

    The media have been rife with reports on trans fats since New York City's Board of Health announced it would phase out these fats in restaurants and other food-service establishments. And that's good news for most consumers because trans fats can pose a double whammy for the heart. Not only can they hike a person's bad cholesterol even more than saturated fats can, but they also reduce...

You had planned to do the same thing each of the next 2 days—until you awake feeling sore from head to toe. The next day you feel even worse, so you settle for spending the rest of your trip in the lodge, sipping...

    Chocolate as Sunscreen

    As if you needed another reason to eat chocolate, German researchers have shown that ingesting types rich in cocoa solids and flavonoids—dark chocolate—can fight skin cancer. Their findings are preliminary because they come from a trial of just 24 women who were recruited to add cocoa to their breakfasts every day for about 3 months.

    Half the women drank hot cocoa containing a...

    Do People Know When They're Overweight?

    A new study finds that most people can estimate their height-weight combinations fairly accurately. However, overweight and obese people miss the mark when they're asked to characterize the healthiness of their weight-to-height status.

    Indeed, among adults who met the National Institutes of Health criteria for being obese, only 15 percent realized they were obese, notes Kimberly P....
