Overview

Why eat peanut butter?

Peanut butter packs plant protein, unsaturated fat, fiber and a long list of minerals into a spread most people already enjoy. It is calorie-dense, so it works best as a topping or a component of a meal rather than something eaten by the spoonful, but nutritionally it earns its place.

Good to know: At 598 kcal per 100 g, portions add up quickly, and unsalted versions like this one keep sodium at just 17 mg per 100 g compared with salted jars.

  1. Protein that satisfies

    Two tablespoons supply 7.11 g of protein (14% DV), which helps keep a snack or slice of toast filling for longer.

  2. Niacin and vitamin E

    Per 100 g it delivers 82% DV niacin, involved in energy metabolism, and 61% DV vitamin E, an antioxidant that protects cell membranes.

  3. Magnesium and copper

    With 168 mg magnesium (40% DV) and 47% DV copper per 100 g, it supports muscle and nerve function plus normal red blood cell formation.
