Walnuts Effective Wall-Nuts

Written by Professor Gordon S. Lynch

Consuming a handful of raw walnuts may protect against artery damage, particularly after fatty meals.

Blood flow through our arteries is regulated, in part, by the "endothelial cells" that line the walls of the blood vessels. These cells help control dilatation and constriction of vessel diameter by producing a gas called nitric oxide that helps keep the arteries flexible. Loss of proper endothelial function is linked to atherosclerosis, or hardening of the arteries, which is common in patients with diabetes and high blood pressure.
