考研英语外刊：健康的生活方式可以一定程度抵消痴呆症的遗传风险

A healthy lifestyle can cut your risk of developing Alzheimer's or other forms of dementia even if you have genes that raise your risk for these mind-destroying diseases, a large study has found.

People with high genetic risk and poor health habits were about three times more likely to develop dementia versus those with low genetic risk and good habits, researchers reported Sunday. Regardless of how much genetic risk someone had, a good diet, adequate exercise, limiting alcohol and not smoking made dementia less likely.

"I consider that good news," said John Haaga of the U.S. National Institute on Aging, one of the study's many sponsors. "No one can guarantee you'll escape this awful disease" but you can tip the odds in your favor with clean living, he said.
