Sweetcorn, baby, boiled in unsalted water

Baby sweetcorn is the immature cob of the maize plant, eaten whole. The figures here describe baby sweetcorn boiled in unsalted water. It provides carbohydrate, fibre and some protein, as well as folate. Per 100g, it contains 4.6g of carbohydrate, 2.4g of fibre, 2.2g of protein and 160µg of folate.

Fibre helps support normal bowel function, while folate is needed for normal cell division and the formation of red blood cells. Baby sweetcorn prepared this way contains only trace amounts of salt and little saturated fat. Adding salt, butter or sauces will change its nutritional content, which may be relevant to people monitoring their intake. Full nutritional figures are in the tables below.
