Yam, flesh only, boiled in unsalted water

Yam is a starchy tuber eaten as a vegetable. The figures here describe the flesh only, peeled and boiled in unsalted water. It mainly provides carbohydrate, with 29g per 100g, alongside 2.3g of fibre and 1.6g of protein. Its energy content is 504 kJ per 100g.

Carbohydrate provides energy for the body, while fibre supports normal bowel function. Boiled yam contains little fat or saturated fat, and only trace amounts of salt when prepared without added salt. Added fats, sauces or salt can change the nutritional content of the finished dish, which may be relevant for people monitoring their energy or salt intake.

About these figures

Values are per 100g of the food as described (8 samples, fresh, imported. Peeled, cut into chunks and boiled for 20-30 minutes). "Trace" means only a very small amount was found. Nutrients that were not measured are not shown. Salt is calculated from sodium.
