Previous studies have suggested an inverse relationship between tree nut consumption and diabetes. Though the findings are correlational, walnuts are uniquely high in omega-3 and omega-6 fatty acids, which may be of particular value in Type 2 diabetes prevention.
The scientists, writing in the April issue of The Journal of Nutrition, used dietary and health data on 138,000 women participating in a large continuing study of women’s health. Beginning in 1999 they collected data on walnut consumption, and followed the women for the next 10 years. They found 5,930 cases of Type 2 diabetes.
