Onions, boiled in unsalted water

Onions are a bulb vegetable, described here after boiling in unsalted water. They provide mainly water, with carbohydrate and fibre, and small amounts of protein and fat. Per 100g, these boiled onions contain 5.4g of carbohydrate, including 4.2g of sugars, and 2.3g of fibre. Their salt content is 0.01g per 100g.

Fibre helps support normal bowel function. The sugars in plain boiled onions occur naturally, rather than being added during cooking. Boiling without salt keeps the salt content low; adding salt, stock or sauces can change this. Butter or oil added before serving will also increase the fat and energy content.
