The U.S. Department of Agriculture classifies peanut butter as a member of the protein foods group. This group includes peanuts in their natural state, as well as peanuts that have been blended into peanut butter.

Two tablespoons of creamy, salt-free peanut butter contain more than 7 grams of protein. Without protein, the body cannot create hemoglobin or effectively maintain the condition of tissue and bones. One serving of peanut butter contains numerous vitamins and nutrients, but some brands are packed with unhealthy ingredients such as refined sugar and partially hydrogenated oils. Peanut butter can be consumed directly from the jar or enjoyed on sliced fruit or bread.
