Spring onions, bulbs and tops, raw

Spring onions are vegetables with a small bulb and green leaves. The figures here describe the raw, peeled bulb and leaves together. They consist mainly of water and provide small amounts of carbohydrate and protein, alongside vitamins and minerals. Per 100g, they contain 3g of carbohydrate, 2g of protein, 26mg of vitamin C and 54µg of folate.

Vitamin C supports normal immune function and helps the body absorb iron from plant foods. Folate is needed for normal cell division and the formation of blood cells. Raw spring onions contain little salt or saturated fat, although ingredients added during preparation can change this. Full nutrient figures are provided in the tables below.
