"Lean gene" raises risk of heart disease, diabetes
英语课
BEIJING, June 27 (Xinhuanet) -- A "lean gene 1" that helps people keep slim was found closely related to diabetes 2 and heart disease, according to a study pulished in Nature Genetics journal on Sunday.
The scientists from Britain’s Medical Research Council Epidemiology Unit conducted the study.
After comparing the genetic 3 codes of more than 75,000 people, a gene called IRS1 was spotted 4 as the decisive factor to lower the fat level in human body.
But in further study, IRS1 was found putting people to a 20 percent higher risk of developing heart disease and type-2 diabetes.
The study warned that people who appear slim and fit might be also at risk.
But scientists suggest that the study results did not change the general message for most people.
"While this study pointed 5 to genes 6 as one factor in determining the risk of developing these conditions, it was important to remember that lifestyle factors like diet, exercise, cutting out smoking and maintaining a healthy weight also play a vital role in reducing the risk," said Ruth Loos, who led the study.（本文由在线英语听力室整理编辑）
