They gave participants a bundle of tests measuring memory, oral ability and attention．The study didn’t include men, but researchers say a similar diet would likely have the same results．
Eating fish can cut risk of heart rhythm disorder
US scientists have found that eating fish can reduce the risk of deadly heartbeat disorders．They say baked fish can effectively reduce the risk of atria fibrillation(心房纖維性顫抖)among older men and women, reported Tuesday’s CRI online．
Researchers say in their 12 years of research among 4,800 people over the age of 65 ,they found those who ate fish one to four times per week had a about 30 percent lower risk compared with those who ate fish less than once a month．They say the pmega-3 fatty acids in fish can reduce the risk of a range of heart disorders and is vital to brain development and function．
More than 2 million Americans are affected by atria fibrillation, a chronic(慢性的)condition that causes shortness of breath and an inability to exercise．
Red wine may extend life
US scientists have found that a mixture that makes red wine a healthy drink may also hold the secret to a longer life．They say antioxidant(抗氧化劑)in wine acted on fruit flies and worms in the same way as a method known to extend the life of many animals, which is by sharply limiting how much they eat．CRIENGLISH．com reported Thursday．
Limiting calories has been shown to make animals such as dogs and monkeys live longer, but they are often tired and lose productivity．
The researchers will begin testing the mixture in mice, which are considerably closer to humans biologically．
