The nuts are rich source of mono-unsaturated fatty (MUF) like oleic acid (18:1) and palmitoleic acids (16:1). Studies suggest that MUF fats in the diet help lower total as well as LDL (bad) cholesterol and increase HDL (good) cholesterol levels in the blood. The Mediterranean diet, which is rich in fiber, MUF fats and antioxidants work favorably in maintaining healthy blood lipid profile and thus offer protection from coronary artery disease and strokes.
