Researchers from the University of Scranton Pennsylvania have shown that walnuts are the healthiest nut, beating pistachios, peanuts, almonds and pecans to the top spot. Dr. Joe Vinson explains that the antioxidant levels were analyzed for nine types of nuts and that a handful of walnuts contained double the levels of the rest.



“Walnuts have been shown to improve endothelial function, another mechanism related to heart disease, and although they are high in heart-healthy polyunsaturated fats (walnuts more than any other nut) consuming them in moderation, one or two handfuls, does not cause weight gain,” he said.
