Sweet potato, raw, flesh only

Sweet potato is a starchy root vegetable. These figures describe the raw flesh of the yellow variety, without the skin. It mainly provides carbohydrate, with 21g per 100g, and also contains several vitamins and minerals. Each 100g provides 655µg of vitamin A as retinol equivalent, 23mg of vitamin C and 370mg of potassium.

Carbohydrate provides energy for the body. Vitamin A supports normal vision and immune function, while vitamin C helps the body absorb iron from plant foods and supports collagen formation. The raw flesh contains little fat or salt, although cooking methods and added ingredients can change the nutritional content of the prepared food. Full nutrient figures are in the tables below.
