Protein

A tablespoon serving of peanut butter contains 7 grams of protein. Your body uses the amino acids found in protein to build and repair muscle tissue. In addition to building metabolism-boosting muscles, protein-rich foods like peanut butter keep you feeling fuller for longer. The protein in peanuts, like other plant proteins, contains an incomplete set of amino acids.

Healthy Fats

The poly- and monounsaturated fats in the spread lower your risk of developing heart disease by reducing the amount of harmful cholesterol in your bloodstream, & also prevent type 2 diabetes. Each 2-tablespoon serving contains 16 grams of total fat, including 7.4 grams of monounsaturated fat and 4.5 grams of polyunsaturated fat.

Potassium

Excess sodium in your diet puts stress on your cardiovascular system, but potassium can counter the negative effects of sodium. It also helps your nerves function properly and aids in heart function. Peanut butter brands with added salt contain two times more potassium than sodium.

Fibre

A 2-tablespoon serving of peanut butter contains about 2 grams of dietary fiber. While not the most fiber-rich of foods, peanut butter can help supplement your fiber intake from other foods. Fiber helps regulate your digestive system by promoting healthy bowel movements, and, like protein, fiber keeps your hunger at bay between meals. The fiber in peanut butter also fights heart disease, type 2 diabetes and obesity.

Just make sure you buy a good quality peanut butter. I personally love whole earth crunchy peanut butter & / or advise you buy another organic brand as many cheaper brands remove a lot of the goodness & add a lot of sugar.
