Health Benefits of Walnuts

Let’s explore some of the health benefits of walnuts in detail.

Good for Heart

Due to the high content of omega-3 fatty acids, walnuts are extremely beneficial for heart, especially in cases of cardiovascular diseases. They have an ample supply of mono-unsaturated fatty acids like oleic acid and essential fatty acids like linoleic acid, alpha-linolenic acid (ALA) and arachidonic acids which help prevent coronary heart diseases by favouring a healthy lipid profile. Consumption of walnuts also helps in the production of HDL or “good” cholesterol and lowering the LDL or “bad” cholesterol. Know about functional foods for heart health here!

Good for Brain

The omega-3 fatty acid content of walnuts helps maintain proper functioning of the brain and nervous system and also aid in improving memory function. Scientific studies prove that a lack of omega-3 fatty acids causes hyperactivity and irritability. Walnuts compensate for the deficient essential fatty acids (EFAs) and uplift the mood; hence they help in battling depression and stress in adults.
