Walnuts, high in antioxidants and and rich in polyunsaturated fatty acids, have been lauded for many health benefits including reducing breast cancer risk. Now they are credited with reducing the risk of diabetes in women who consume two or more servings per week, according to a Harvard University study. Eating just a few ounces of walnuts per week was associated with a 21% and 15% lower risk of incident type 2 diabetes. Researchers examined two 10-year studies with nearly 140,000 healthy women aged between 35 and 77 years. Previous studies have also shown regular unsalted consumption of nuts improves blood glucose, lower the “bad” LDL cholesterol.
