Walnuts are rich in omega-3 and are an ample source of monounsaturated fatty acids (72%) like oleic acid. It also contains EFAs like linoleic acid, alpha-linolenic acid (ALA), and arachidonic acids. Scientific studies prove that the inclusion of walnuts in any diet helps prevent coronary heart diseases by favoring a healthy lipid supply. Their consumption lowers the bad LDL cholesterol and increases the level of good HDL cholesterol. Daily consumption of 25 grams of walnuts provides 90% of the recommended daily intake (RDI) of EFAs, which in turn lowers the risk of high blood pressure and heart diseases. One of the health benefits of consuming walnuts is that it improves the body metabolism. They, along with EFAs, provide minerals like manganese, copper, potassium, calcium, iron, magnesium, zinc, and selenium to the body. These minerals help contribute to metabolic activities like growth and development, sperm generation, digestion, and nucleic acid synthesis.
