...Medicine, details the results of a 15-year study of 121,700 registered nurses. The researchers, headed by SPH Assistant Professor of Medicine in the Department of Nutrition Edward L. Giovannucci, found that of the 88,756 nurses eligible for the study, those who had taken multivitamin substitutes containing folic acid, otherwise known as folate, for more than 15 years had a markedly lower chance of getting colon cancer...
...kind of vegetables we need. Just look at the latest results, reported last week, of the Nurses' Health Study, an ongoing research program that is tracking the health habits of more than 120,000 nurses. Researchers determined that women who daily consumed at least 400 micrograms of folic acid--one of the B vitamins--in either leafy green vegetables or multivitamin pills reduced their risk of colon cancer as much as 75% over 15 years. Before you decide to replace broccoli with vitamins, however, remember that there are thousands of healthful compounds in fresh vegetables that simply...
FOLATE FOR ALL A new recommendation for women of childbearing age: take a daily supplement of 400 micro-grams of folic acid, a B vitamin, to prevent birth defects. A separate study finds that eating cereal fortified with 400 mcg of folic acid can lower a man's blood levels of homocysteine, an amino acid linked to heart disease...
...scientists always agree. "Folic acid is a perfect example," says Rima Apple, a historian at the University of Wisconsin at Madison and author of Vitamania: Vitamins in American Culture. In 1989 the recommended dietary allowance for folic acid was cut from 400 micrograms for all adults to 200 micrograms for men and 180 micrograms for women, because that was the lowest amount that would stave off a nutritional deficiency. At the same time, however, new studies were showing that higher doses of folic acid could prevent crippling birth defects during pregnancy and ward off strokes and heart attacks in older...
...FLAWED FOLIC ACID Pregnant women need folic acid to prevent neural-tube defects in babies. But they may not be getting it: the folic acid in at least half the prenatal vitamins studied doesn't fully dissolve in liquid, suggesting it's not absorbed...
