Health benefits of Peanuts
- Peanuts are rich in energy and contain many health benefiting nutrients, minerals, antioxidants and vitamins that are essential for optimum health.
- They are especially, rich in mono-unsaturated fatty acids like oleic acids that help to lower LDL or “bad cholesterol” and increase HDL or “good cholesterol”. Research studies suggest that Mediterranean diet, which is rich in monounsaturated fatty acids helps to prevent coronary artery disease and strokes by favoring healthy blood lipid profile.
- These nuts are good source of dietary protein compose fine quality amino acids that are essential for growth and development.
- Research studies have shown that peanuts contain high concentrations of poly-phenolic antioxidants, primarily in p-coumaric acid, which is believed to reduce the risk of stomach cancer by reducing the formation of carcinogenic nitrosamines.
- Peanuts are excellent source of resveratrol, another polyphenol antioxidant, which has been found to have protective function against cancers, heart disease, degenerative nerve disease, Alzheimer’s disease, and viral/fungal infections.
- Studies suggests that resveratrol reduces stroke risk by alteration of molecular mechanisms in blood vessels (reducing susceptibility to vascular damage through decreased activity of angiotensin, a systemic hormone causing blood vessel constriction that would elevate blood pressure) and by increasing production of the vasodilator hormone, nitric oxide.
- Recent research studies suggest that boiling enhances antioxidant concentration in the peanuts. It has been found that boiled peanuts have two and four fold increase in isoflavone antioxidants biochanin A and genistein content, respectively. (Journal of agricultural and food chemistry).
- The nuts are an excellent source of vitamin E (a-tocopherol); containing about 8 g per100 g. vitamin E is a powerful lipid soluble antioxidant which helps maintain the integrity of cell membrane of mucus membranes and skin by protecting from harmful oxygen free radicals.
- The nuts are packed with many important B-complex groups of vitamins such as riboflavin, niacin, thiamin, pantothenic acid, vitamin B-6, and folates. 100 g of peanuts provide about 85% of RDI of niacin, which contribute to brain health and blood flow to brain.
- The nuts are rich source of minerals like copper, manganese, potassium, calcium, iron, magnesium, zinc, and selenium.
Just a hand full of peanuts per day provides enough recommended levels of phenolic anti-oxidants, minerals, vitamins, and protein.
