Edible mushrooms, such as Shiitake, Reishi, Chaga, Lion's mane, Maitake, Agaricus, etc., are generally rich in protein, polysaccharides (beta-gluten), and fibers. Those are the basic nutrients required by the human body.
Taking whole mushroom powders as a "meal replacement" is the best way to keep the entire nutrition profile. Super-food powder blends would be the most ideal option – just use the spoon and take it with water, it is all that simple!
Furthermore, most of these powder blends available in the market are flavored and taste enhanced, you can choose your favorite one, either strawberry, mango, pineapple, or banana …… and enjoy!
