This is not the first time that scientists have lauded broccoli's anticancer benefits. Johns Hopkins' Dr. Paul Talalay and his colleagues first isolated sulforaphane from broccoli in 1992. Tests showed that the compound reduced the incidence of breast tumors in rats by 60%. While vitamin E and other antioxidants attack rogue cancer-causing molecules directly, sulforaphane works indirectly by boosting the body's cancer-fighting defenses. Not all broccoli plants are created equal, however. The amount of sulforaphane found in fresh broccoli varies wildly, making the vegetable an unreliable anticancer agent...
...BONE UP For the first time, a study shows that older men, like women, can stave off bone loss--and even increase bone mass--with calcium and vitamin D supplements. Just 500 mg of calcium and 700 IUs of vitamin D a day seem to do the trick...
While marine biologists like Klimley and Holland are trying to unravel the mysteries of sharks' behavior and their role in the marine food chain, immunologists and physiologists are attempting to understand the animals' biochemistry. The idea that sharks can actually be beneficial to human health was established decades ago: vitamin A came primarily from shark-liver oil until 1947, when it was first synthesized in the laboratory. The unctuous liquid is also, for reasons still unknown, highly effective in shrinking human hemorrhoids...
...knows for certain what causes some individuals and not others to overproduce homocysteine. But the evidence points to a shortage of vitamin B6, vitamin B12 and folic acid, all of which work to convert the amino acid into a molecular form the body can use. The answer for people concerned about cardiac health would seem to be for them to keep their intake of the protective vitamins high. The Harvard Health Letter has recommended increasing consumption of a range of foods--including leafy green vegetables, beans, peas, grains and certain meats and dairy foods--to keep homocysteine in check. Many...
BEATING HIGH BLOOD PRESSURE Wolfing down 2.5 grams of potassium per day, about twice the average intake, can lower blood pressure almost as well as drugs do. That means eating lots of citrus fruits and leafy vegetables--or taking vitamin supplements...
