A study has found that eating a few walnuts towards the end of a meal can help reduce the damage greasy food does to arteries.
Because eating high-fat food disrupts the production of nitric oxide in the arterial walls, and walnuts contain a component that reduces arteriosclerosis and keeps arteries supple. They also contain antioxidants and alpha-linolenic acid, which all protect nitric oxide, thus protecting the arteries and contributing to good health.
Health Perspective: Nitric oxide can promote fibroblasts to secrete collagen, which can increase skin elasticity. Walnuts are a type of nut. Eating walnuts after a meal helps prevent the disruption of nitric oxide production in the arterial walls and can also effectively soften blood vessels.
