Tannia, raw

Tannia is a starchy tropical root vegetable grown for its edible underground stems, known as corms. The figures here describe tannia in its raw form. It mainly provides carbohydrate, with 25g per 100g, and contains 0.4g of fat. It also provides 16mg of vitamin C and 480mg of potassium.

Carbohydrate provides energy, while potassium supports normal nerve and muscle function. Vitamin C helps the body form connective tissue and absorb iron from plant foods. Although these figures are for raw tannia, it should be cooked before eating because naturally occurring calcium oxalate crystals can irritate the mouth and throat. Cooking can change its nutrient content. Full figures are in the tables below.
