Onions, raw

Onions are bulb vegetables, and the figures here describe them raw. They contain mostly water and provide carbohydrate, with some fibre and small amounts of protein and fat. Per 100g, raw onions contain 8g of carbohydrate, including 6.2g of sugars, alongside 2.2g of fibre and 0.1g of fat.

Fibre helps support normal bowel function, while carbohydrate provides energy for the body. The sugars in raw onions occur naturally within the vegetable rather than being added. Raw onions contain very little salt, although salt and fat added during cooking can change the nutritional content of a dish. Full nutritional figures are shown in the tables below.
