Portobello mushrooms can be consumed raw, although Dr. Andrew Weil warns against doing so for any type of mushroom. Toxic and potentially dangerous carcinogens are present in raw mushrooms.
Mushrooms have a hard outer wall and are difficult to digest if not cooked, according to Dr. Weil. Important nutrients like B vitamins, minerals, and proteins are released when mushrooms are cooked.
Dr. Weil claims that sauteeing, broiling, or grilling any type of mushroom before eating helps to break down many of the potentially dangerous toxins. Many people believe that grilling and broiling are the finest methods for preparing mushrooms.
