    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.

    Power from heat

    The thermoelectric effect can produce small amounts of electricity from almost any source of heat, but its low efficiency has so far limited its uses. A team has now found a simple way to make one thermoelectric alloy more efficient.

    When two ends of a stick of a thermoelectric material are exposed to different temperatures, a voltage appears. The electrons in the stick act like the...

    Fabulon: Looking less fabulous

    Researchers have tentatively linked polychlorinated biphenyls (PCBs) in people—and their dwellings—with Fabulon, a product used throughout the late 1950s and 1960s as a durable top coat for hardwood floors.

    During a survey of 120 homes on Cape Cod, Mass., researchers found two houses with unusually high PCB concentrations in air and house dust. Residents in both homes remembered a...

    No Peanuts for Your Peanut

    Peanuts are a protein-rich snack food packing plenty of vitamins and trace nutrients. However, these legumes can elicit potentially life-threatening immune reactions within the one in 100 American adults who are allergic to them. Rates of peanut allergy are even higher among children. And the really disturbing news: A new study finds that the age at which this common food allergy first shows...

    A Melon for Dieters and Diabetics

    Mention watermelon and people immediately think of sweet, juicy, crimson-colored fruit. But watermelons didn't start that way, notes Angela R. Davis of the U.S. Agricultural Research Service. Wild watermelons in their native Africa are white fleshed, the size of softballs, and "hard like softballs," she notes. Bitter and anything but sweet, watermelons hardly started as dessert.

    Want that fiber regular or decaf?

    Researchers in Spain report that a cup of coffee can deliver a significant portion of daily dietary fiber. The drink hadn't been known to contain any fiber.

    Like the cholesterol-lowering substances found in oat bran, fiber in coffee consists of carbohydrates that the body can't digest, but which dissolve in digestive fluids. However, unlike oat bran's soluble fiber, the fibrous...

    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...

    A New Bible for Eating Well

    A new book offers one-stop shopping for authoritative nutrition advice—the first time the Institute of Medicine in Washington, D.C., has issued such a tome in nearly 2 decades. It summarizes a wealth of the institute's eating guidelines that have been trickling out over the past decade.

    Since at least the 1950s, people who wanted to know how much of some vitamin or mineral they...

    Juice May Slow Prostate Cancer Growth (with recipe)

    Prostate cancer will claim the lives of an estimated 30,000 men in the United States this year. The second leading cause of cancer death in men, its incidence climbs with age. In Western countries, the disease is reaching nearly epidemic proportions among the elderly. However, the cancer can grow so slowly that many men with prostate cancer will die of something else first.
