Cashews are high in calories. 100 g of nuts provide 553 calories. They are packed with soluble dietary fibre, vitamins, minerals and numerous health-promoting phyto-chemicals that help protect from diseases and cancers. They are rich in “heart-friendly” monounsaturated-fatty acids like oleic, and palmitoleic acids. These essential fatty acids help lower harmful LDL-cholesterol while increasing good HDL cholesterol in the blood. Research studies suggest that Mediterranean diet which is rich in monounsaturated fatty acids help to prevent coronary artery disease and strokes by favouring healthy blood lipid profile. Cashew nuts are abundant sources of essential minerals. Minerals, especially manganese, potassium, copper, iron, magnesium, zinc, and selenium are concentrated in these nuts. A handful of cashew nuts a day in the diet would provide enough of these minerals and may help prevent deficiency diseases. Selenium is an important micronutrient, which functions as a co-factor for antioxidant enzymes such as Glutathione peroxidases, one of the most powerful antioxidants in the body. Copper is a cofactor for many vital enzymes, including cytochrome c-oxidase and superoxide dismutase (other minerals function as co-factors for this enzyme are manganese and zinc). Zinc is a co-factor for many enzymes that regulate growth and development, gonadal function, digestion, and DNA (nucleic acid) synthesis. Further, the nuts are also hold a small amount of zea-xanthin, an important pigment flavonoid antioxidant, which selectively absorbed into the retinal macula lutea in the eyes. It is thought to provide antioxidant and protective UV ray filtering functions and helps prevent age-related macular degeneration (ARMD) in the elderly.
