Shiitake mushrooms contain a lot of dietary fiber and improve the intestinal environment. It is especially high in insoluble dietary fiber, which absorbs water and expands in the stomach and intestines, which activates intestinal movements and is effective in preventing constipation.

It also contains ergosterol, a precursor of vitamin D, which converts to vitamin D when exposed to sunlight. Vitamin D increases calcium absorption and strengthens bones.

Just exposing fresh shiitake mushrooms to sunlight for about 30 minutes increases vitamin D, so it's a good idea to expose them to sunlight before cooking.
