About Peanuts

One ounce of raw peanuts provides approximately 159 calories, 7.2 grams of protein, 4.5 grams of carbohydrate, 13.8 grams of fat, and 2.4 grams of fiber. The serving contains about 2.1 grams of net carbohydrate and has a low glycemic load.

Although commonly grouped with nuts, peanuts are botanically legumes. They provide niacin, folate, vitamin E, magnesium, manganese, copper, phosphorus, and a substantial amount of plant protein.

Use peanuts in measured snack portions, salads, stir-fries, or sauces. Choose unsalted versions for sodium control, and remember that peanuts are a major allergen that requires strict avoidance for affected individuals.
