Uppfyller patientens redaktionella riktlinjer

White mushrooms are edible fungi; the figures here describe raw button and closed-cap mushrooms. They consist mainly of water and provide small amounts of protein and fibre, alongside B vitamins and minerals. Per 100g, they contain 1g of protein, 0.7g of fibre, 378mg of potassium and 0.27mg of riboflavin.

Potassium contributes to normal nerve and muscle function, while riboflavin helps the body release energy from food. Raw white mushrooms contain little fat, saturated fat or salt. Added ingredients, such as butter, oil or salt, will change the nutritional content of a prepared mushroom dish. Full nutritional figures are given in the tables below.
