More Reasons to Eat Like a Greek

Now, researchers at Tufts University’s USDA Human Nutrition Research Center on Aging in Boston report that two foods in that diet – nuts and olive oil – can lower the risk for strokes in older people whose genetic make-up increases their risk for diabetes. Researchers randomly assigned 7,018 people, ages 55- to 80-years, to a low-fat diet, a Mediterranean diet high in nuts, or a Mediterranean diet high in extra-virgin olive oil. Some of the participants had a genetic trait in common – they shared a mutation in a gene that increases the risk for type 2 diabetes by as much as 50%.  At the end of five years, results showed that those people with the mutation who followed the low-fat diet were almost three times more likely than others to have a stroke, but those on the Mediterranean diets had a risk about equal with those without the genetic mutation. The researchers conclude that “…switching to a Mediterranean diet …will help those people with risk factors or a family history of disease.” Apparently, even incorporating a few elements of that diet, in this case nuts and/or olive oil, can be helpful.
