Walnuts May Boost Heart Health in Diabetics

Daily consumption of walnuts, rich in polyunsaturated fatty acids, may improve the health of blood vessels, thereby decreasing the risk of heart disease, says a new study from Yale.


Supplementing the diet of middle aged diabetics with 56 grams of walnuts led to significant improvements in the function of the blood vessel lining (endothelium), and there was also a trend towards improved cholesterol levels, according to findings published in Diabetes Care.


Study results showed a significant blood flow improvement of 2.2 percent in the participants eating walnuts. Blood sugar levels and total cholesterol levels were also decreased from baseline values.


The study adds to a growing body of science supporting the health benefits, and the heart benefits in particular, of increased consumption of nuts. Previous studies have reported benefits for almonds, macadamia, and pistachios.
