Peanuts are not actually nuts. They are legumes that grow in warm climates in Asia, Africa, South America and the United States. This complex plant food offers a nutritious combination of protein, fiber, vitamins, minerals, antioxidants and healthy fats.
Protein and Fiber
One ounce of raw peanuts contains 7.3 grams of protein and 2.4 grams of fiber. The plant protein arginine helps produce more energy and improve blood circulation. Peanuts' protein content also provides a high rate of satiety.
Vitamins and Minerals
Peanuts are rich in niacin, thiamin, riboflavin, folate, vitamin E, magnesium, potassium and copper.
Antioxidants
Peanuts contain resveratrol, the plant chemical touted as an aid against cardiovascular disease, inflammation, cancer and aging. The phytosterols in peanuts help prevent the body from absorbing "bad" LDL cholesterol.
Healthy Fats
Peanuts have a much higher concentration of monounsaturated and polyunsaturated fat than saturated fat. As a plant protein, peanuts are cholesterol-free.
