cashew nuts, like most nuts, are high in protein and low in carbohydrates and packed with soluble dietary fiber, vitamins, minerals and numerous health-promoting phytochemicals. They are rich in "heart-friendly" monounsaturated-fatty acids like oleic and palmitoleic acids, abundant in essential minerals like manganese, potassium, copper, iron, magnesium, zinc, and selenium, as well as a good source of B vitamins and folate.
