Cashew nuts – nutritional facts and health benefits

Cashews have a buttery, sweet, and salty taste, an unmistakable shape, and they are an excellent source of vitamins and minerals. They grow on cashew nut trees, which are native to subtropical climates.

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.

Cashews are also good in many essential vitamins such as pantothenic acid (vitamin B5), pyridoxine (vitamin B-6), riboflavin, and thiamin (vitamin B-1). 100 g nuts provide 0.147 mg or 32% of daily-recommended levels of pyridoxine. Pyridoxine reduces the risk of homocystinuria, and sideroblastic anemia. Niacin helps prevent “pellagra” or dermatitis. Additionally, these vitamins are essential for metabolism of protein, fat, and carbohydrates at the cellular level.

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.

Another ingredient in cashews is proanthocyanidins, which contain flavanols that inhibit the ability of cancer cells to divide and multiply, reducing incidences of colon cancer.

Data collected on 80,718 women from the Nurses’ Health Study demonstrate that women who eat at least an ounce of nuts each week, such as cashews, have a 25% lower risk of developing gallstones.

Cashew nuts are also 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 favoring healthy blood lipid profile.
