Effective Walnuts

Effective Walnuts

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.

The foods we eat affect endothelial function. Foods rich in antioxidant vitamins, the amino acid L-arginine and polyunsaturated fatty acids (PUFAs), have been shown to improve endothelial function while eating high-fat meals has the opposite effect. Fat molecules trigger an inflammatory reaction which temporarily disrupts the production of nitric oxide, reducing the elasticity of the arteries. Over time, this can lead to atherosclerosis.

Walnuts are a rich source of antioxidants, L-arginine and alpha-linoleic acid, a plant-based PUFA. In 2004, a team of Spanish researchers showed that, compared with a Mediterranean diet, a walnut diet improved endothelial function in patients with high cholesterol.

To consumers, the basic building blocks of nutrients are well known: essential amino acids, essential fatty acids, vitamins and minerals. What Mannatech has discovered is a brand new category of important nutrients: glyconutrients. Following their initial breakthrough discovery, Mannatech filed patents across the globe. Ambrotose® complex has now been issued patents in 29 countries, including the United States. Securing its position of leadership, Mannatech dedicates approximately 30 employees to its science department, and continues to develop new technologies, review research, and conduct studies.
