Peanuts, kernel only, plain, unsalted

Peanuts are the edible seeds of a legume, although they are usually grouped with nuts in food tables. The figures here describe plain, unsalted peanut kernels, without their shells. They mainly provide fat and protein, with some carbohydrate. Per 100g, they contain 46g of fat, 26g of protein and 2341 kJ of energy, with 0.01g of salt.

Protein supports the growth and repair of body tissues. Most of the fat in peanuts is unsaturated, although they also contain saturated fat. Their concentrated energy content is worth noting for people monitoring energy intake. Peanuts are also a food allergen and can cause severe reactions in people with peanut allergy.
