The human body needs fat as part of any diet, and eating nuts ensures that fat intake comes from healthy unsaturated fat rather than saturated fat found in animal products, which is harmful. Walnuts particularly, boost the healthy fat intake because of the alpha-Linolenic acid they contain, which is an omega-3 fatty acid. This type of fat supports the brain function, strengthens your red blood cells and helps fight excess inflammation.
A diet that includes walnut kernels, other nuts and seeds also keeps the body healthy as it ages by preventing disease. Those who eat nuts frequently tend to weigh less than people who rarely consume them, as well as face a lower risk for weight gain. Nuts and seeds also reduce the levels of inflammation in the human body and the risk of heart disease and type 2 diabetes, according to the Linus Pauling Institute.
