Walnut

"Wonderful Walnuts and Their Health Benefits"

Walnuts high in polyunsaturated fat, fiber, thiamine, vitamin B6, and minerals like magnesium and zinc (1,2). It has been proved that a daily intake of 30 g of walnuts contributes to the improvement of the elasticity of blood vessels (3).

Walnuts may also help to reduce the risk of heart disease and have also been shown to lower LDL “bad” cholesterol and blood pressure, two major risk factors for cardiovascular disease (4).
