Walnuts are rich in polyunsaturated fatty acids and have been shown to improve various cardiometabolic risk factors. Researchers in a Journal of Nutrition study examined the association between walnut intake and incident type 2 diabetes in 137,956 women over without diabetes, cardiovascular disease, or cancer. Consumption of walnuts and other nuts was assessed every 4 years.
A total of 5930 incident type 2 diabetes cases during 10 years of follow-up were discovered. Walnut consumption for participants consuming 1–3 servings per month (1 serving = 28 g), 1 serving per week, and more than 2 servings per week were at 7%, 19%, and 33% lower risk of type 2 diabetes respectively, compared with women who never/rarely consumed walnuts.
The consumption of total nuts and other tree nuts was also inversely associated with risk of type 2 diabetes, and the associations were largely explained by body mass.
Simply, higher walnut consumption is associated with a significantly lower risk of type 2 diabetes in women.
