Yam, flesh only, raw

Yam is a starchy root vegetable. The figures here describe its raw flesh only, without the skin. Per 100g, it provides 488 kJ of energy, 28g of carbohydrate, 1.5g of protein and 380mg of potassium. Carbohydrate is its main energy-providing nutrient, while its fat content is low.

Carbohydrate is broken down during digestion to provide energy for the body. For people monitoring carbohydrate intake, the total carbohydrate content is relevant, not just the sugar content. Potassium contributes to normal nerve and muscle function. Cooking and added ingredients can change the nutrient content of the food as eaten. Full nutritional figures are provided in the tables below.
