Improve heart health

Walnuts are abundant in omega-3 fatty acids, which have been demonstrated to aid promote heart health, according to the National Institutes of Health (NIH). L-arginine, an amino acid, and monounsaturated fatty acids, such as oleic acid, make up 72% of the fat in fresh, raw walnuts. Alpha-linolenic acid (ALA), arachidonic acid, and other important fatty acids (EFAs) are also present in it. By promoting a healthy lipid supply, including these nuts in any diet will help avoid coronary heart problems.

According to research in the journal Metabolism, participants who consumed walnuts had considerably lower levels of LDL (the bad kind of cholesterol) and higher levels of HDL (the good kind). Walnut consumption also decreased ApoB levels, a marker used to assess the risk for cardiovascular disorders, according to German researchers at the University of Munich Medical Center.
