After last year’s widely reported finding that the Mediterranean Diet (fish, poultry, olive oil, fruits, nuts and whole grains, with little meat and dairy) indeed benefits cardiovascular health, now here’s a new study, published in the April 30, 2013 issue of the journal Neurology, and taken up by our hometown newspaper the New York Times, in their online blog “Well”:
Researchers prospectively followed 17,478 mentally healthy men and women 45 and older, gathering data on diet from food questionnaires, and testing mental function with a well-validated six-item screening tool. They ranked their adherence to the Mediterranean diet on a 10-point scale, dividing the group into low adherence and high adherence. […]
During a four-year follow-up, 1,248 people became cognitively impaired. But those with high adherence to the diet were 19 percent less likely to be among them. This association persisted even after controlling for almost two dozen demographic, environmental and vascular risk factors, and held true for both African-Americans and whites.
