Peanuts are an important source of vitamins and mineral salts, useful for the health of the skin and the nervous system. Peanuts, also known as American peanuts, are very proteinaceous seeds (composed of about 28% protein) and a precious natural source of various substances useful for health such as vitamins E and PP, folic acid, arginine and coenzyme Q10 (present in few other foods). They provide the body with a good supply of fiber and mineral salts, including zinc, potassium, phosphorus, manganese, magnesium and copper. Peanuts are very powerful natural antioxidants, like strawberries, blackberries and carrots. They keep the body young and preserve the beauty of the skin. Their arginine content makes them valuable for growing children, while vitamin PP is important for blood circulation and nervous system health. The excellent concentration of folic acid makes peanuts a food that stimulates fertility and is essential during pregnancy. Studies have shown that peanuts, thanks to coenzyme Q10, are a valid aid for those suffering from headaches.
