    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.

    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...

    Sour Genes, Yes—Salty Genes, No

    Some people abhor broccoli, complaining about its intensely bitter taste. Others (myself included) find broccoli's flavor interesting and pleasing—decidedly, not bitter. What leads to our differing culinary opinions is the possession of, or lack of, (in my case, evidently) genes conferring a super sensitivity to bitter taste. Science has recognized such genetic differences for at least a...

    Tea—Milking It

    I'm a serious tea drinker. I'll down it hot or cold, plain or with lemon. Like most Americans, however, I don't regularly add milk. But when my colleague David Lindley, an editor here at Science News, was growing up, his family certainly did.

    Being a Brit, David comes from a culture that holds considerable reverence for this brew and might be accused of being fussy about its preparation...

    Chocolate Constituent Bests Fluoride

    "Chocolate Toothpaste? Extract of Tasty Treat Could Fight Tooth Decay."

    That's how Tulane University's news office provocatively titled a press release it issued last week. Sound sweet? Unfortunately, it's anything but. The extract, theobromine, is a bitter constituent of a number of plants, including the beans used to make chocolate. A chemical cousin to caffeine, this...

    Slimming on oolong

    Without skimping on portions, rats eating diets including oolong tea gain less weight than those dining teafree, a new study finds. The tea apparently impairs the body's ability to absorb fat.

    The finding supports a weight-control strategy—oolong consumption—advocated by practitioners of traditional Chinese medicine, note Lauren E. Budd and her colleagues at the University of California...

    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...

    Red Heat Might Improve Green Tea

    Most tea drinkers don't give much thought to how tea leaves are processed prior to arriving in a tin or tea bag. However, a Korean team of food scientists has. Realizing that many people are trying to consume more of certain tea-derived antioxidants—especially compounds called catechins—the researchers wondered whether concentrations of those chemicals might be affected by tea-leaf handling....

    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.
