Pistachio nuts are not only delicious, but also nutritionally wholesome. They have high amounts of proteins, minerals and fat, predominantly monounsaturated, like that found in olive oil. They are also an excellent source of antioxidants, vitamins E and B6, and iron, calcium, manganese and potassium, among others. Pistachio nuts help reduce bad cholesterol, increase hemoglobin levels and prevent heart problems.

Cashews have a smaller fat content than most nuts, with roughly 75% consisting of unsaturated fatty acids. About 75% of this unsaturated fatty acid content is oleic acid, which is the same monounsaturated fat found in olive oil. Various studies have shown that oleic acid promotes cardiovascular health, even with diabetics. Studies show that monounsaturated fat, when added to a low-fat diet, can help to reduce high triglyceride levels. Triglycerides are a form in which fats are carried in the blood.
