More research shows grapes are great for you

摘要

Grapes are continuing to attract attention as a prescription for good health. Results of two studies investigating the anti-clotting effects of three juices indicate that purple grape juice may provide the best defence against platelet activity (clotting) that can result in heart disease. Researchers at the University of Wisconsin have completed preliminary studies — one apparently the first such study conducted on humans, the other involving rhesus monkeys — that indicate the flavonoids present ingrape juice exhibit "anti-clotting" effects similar to those of aspirin. The studies compared the effects of three different juices on platelet aggregation — orange, grapefruit and purple grape juice. Only the purple grape juice reduced clotting activity significantly, by 39 per cent in humans and 49 per cent in monkeys.
