Hazelnuts, kernel only

Hazelnuts are nuts, and the values here refer to the edible kernels only, without the shells. They mainly provide fat, alongside protein and fibre. Per 100g, hazelnut kernels contain 64g of fat, 14g of protein and 6.9g of fibre. They also provide vitamin E, with 25mg in the same amount.

Most of the fat in hazelnuts is unsaturated. Their high fat content means they are energy-dense, which is worth noting for people monitoring energy intake. Fibre supports normal bowel function, while vitamin E helps protect cells from oxidative damage. Full nutrient figures, including energy, saturated fat and salt, are in the tables below.
