Peanuts are a good source of protein, providing essential amino acids for building and repairing tissues. They are packed with healthy fats, including monounsaturated and polyunsaturated fats, which can help lower cholesterol levels and reduce the risk of heart disease.  Peanuts are also a rich source of vitamins and minerals, such as vitamin E, magnesium, and potassium, which are important for overall health and well-being.
