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. High levels of triglycerides are linked with an increased risk for heart disease, so making sure that you have some monounsaturated fats in your diet by enjoying roasted cashews is a good idea. Just a quarter-cup of these delicious nuts supplies over 37% of your daily recommended value for monounsaturated fat.
