Sweetcorn, kernels, boiled 'on the cob' in unsalted water

Sweetcorn is the edible kernels of maize, eaten as a vegetable. These figures describe kernels boiled on the cob in unsalted water. It mainly provides carbohydrate and fibre, with some protein and a small amount of fat. Per 100g, it contains 9.5g of carbohydrate, 5.1g of fibre, 3.6g of protein and 1.9g of fat.

Carbohydrate provides energy, while fibre helps support normal bowel function. Sweetcorn prepared in unsalted water contains only trace amounts of salt. Adding salt or salted butter will increase the salt content, and butter will also add fat, including saturated fat. These additions are not included in the figures for the boiled kernels. Full nutritional figures are shown in the tables below.
