Peanuts, dry roasted

Peanuts are the edible seeds of a legume, usually grouped with nuts for food and nutrition purposes. These figures describe dry-roasted peanuts, which mainly provide fat and protein, alongside fibre and some carbohydrate. Per 100g, they contain 50g of fat, 26g of protein, 7.6g of fibre and 2g of salt.

Protein is needed for the growth and repair of body tissues, while fibre supports normal bowel function. The fat content contributes to their energy content, which is worth noting when monitoring energy intake. The salt content is also relevant for people limiting salt, and may vary between products. Peanuts are a food allergen. Full nutritional figures are in the tables below.
