Mushrooms, oyster, raw

Oyster mushrooms are edible fungi, grouped with vegetables in food composition tables. The figures here describe them raw. They contain mainly water and provide some protein, B vitamins and minerals, with little fat. Per 100g, they contain 1.6g protein, 0.2g fat, 0.43mg riboflavin and 1.9mg iron.

Riboflavin helps the body release energy from food, while iron is needed to make haemoglobin, which carries oxygen in the blood. The iron in mushrooms is less readily absorbed than iron from meat. Added oil, butter or salt will change the fat, energy or salt content of a prepared dish. Full nutrient figures are in the tables below.
