Eating a Mediterranean diet and following national recommendations for physical activity are each associated with a reduced risk of death over a five-year period, according to two reports in the Dec. 10/24 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. Both studies use data from the National Institutes of Health-AARP Diet and Health Study, which began when questionnaires were returned from 566,407 AARP members age 50 to 71 in six states between 1995 and 1996.
