Peanut flour is a gluten-free and vegan alternative that can provide powerful plant protein and lots of nutrition. Because most of the fat is removed, it is a highly concentrated protein and contains about 10 to 15 grams of protein per ounce. It is also packed with essential nutrients and bioactives. One small scoop (2 tablespoons) of peanut flour is a good source of folate, zinc, and potassium and an excellent source of fiber, magnesium, phosphorus, and niacin (USDA National Nutrient Database, 2009).
Peanuts, peanut butter, and peanut oil are known for their heart-healthy benefits, and peanut flour is no exception. In fact, one study showed that hamsters on a high-cholesterol diet who were fed fat-free peanut flour had significantly decreased cholesterol levels and reduced development of atherosclerosis (Stephens, 2010).
Peanuts contain more arginine than any other food, and peanut flour contains twice the amount than peanuts per serving. Arginine has been shown to play a role in opening up blood vessels to improve blood flow. Also, peanut flour is an excellent source of niacin, a vitamin often prescribed by doctors for its heart-protecting qualities. Plus, peanut flour is a good source of potassium and an excellent source of magnesium, two nutrients that help maintain normal blood pressure (Zhang, 2008 and Champagne, 2008).
Partially defatted peanut flour is available both for commercial and home use in a variety of fat and roast levels.
