Overview While it's important to enjoy everything in moderation, adding peanuts to your diet can boost your health because this common nut ranks as a top source of several vitamins and phytonutrients. Ellagic acid Peanuts are a top source of ellagic acid, a "very potent antioxidant and free radical scavenger," reports Rutgers Cooperative Research & Extension. While antioxidants have several benefits in terms of cellular health, ellagic acid might reduce your risks of cancer. Fiber Peanuts are a top source for fiber, with a single 3 oz. serving netting you 8 grams of fiber, which is more than a slice of whole wheat bread, according to the University of Wisconsin-Stevens Point Health Service. General benefits of fiber include better digestion, reduced cholesterol levels in your blood, and potential benefits to weight management because fiber makes you feel full so you're less apt to eat too much. Healthy fats Not all fats are bad for you. Peanuts are rich in omega-3 fatty acids and other poly- and monounsaturated fats, which are typically referred to as healthful fats. These fats boost cardiovascular health and reduce your risk of health problems such as heart attacks. Coenzyme Q10 Peanuts are a top dietary source of coenzyme Q10. This enzyme helps with numerous body functions such as muscle performance, heart health and reduced blood pressure. Folate When it comes to nuts as a whole, peanuts are the best nut for folate, according to Harvard Medical School. Folate is critical for proper cell growth, healthy red blood cell counts, enhanced metabolism and pregnancy health.
