A handful of peanuts per day provide enough recommended levels of phenolic antioxidants, minerals, vitamins, and protein. The nuts are a rich source of minerals like copper, manganese, potassium, calcium, iron, magnesium, zinc, and selenium.
Some of the other benefits are -
1. Peanuts have monounsaturated fatty acids (MUFA) that helps lower LDL or "bad cholesterol" and increases HDL or "good cholesterol” level in the blood
2. A good source of dietary protein
3. Peanuts contain high concentrations of antioxidants
Roasting/boiling enhances antioxidant content of the peanuts.
