Sweetcorn, kernels, 'on-the-cob', raw, weighed with core

Sweetcorn is a cereal crop whose kernels are eaten as a vegetable. This entry describes raw sweetcorn on the cob, weighed with the core included, with nutrient values calculated from the kernels. Per 100g of whole cob, it provides 4.8g carbohydrate, 2g protein, 1.1g fat and 5mg vitamin C. These figures are not directly comparable with values for kernels weighed without the core.

Carbohydrate provides energy, while protein supports the maintenance and repair of body tissues. Vitamin C supports normal collagen formation and helps the body absorb iron from plant foods. The raw sweetcorn contains only trace salt; added salt or butter will change its nutritional content. Full nutrient figures are in the tables below.
