Most people don’t realize that gourmet mushrooms have so much nutritional value. Take shiitake mushrooms, for example. Shiitake mushrooms are loaded with vitamins. One serving of shiitake mushrooms (1 cup cooked, 133 calories) has the following RDA for males 19-29 years of age (so for females or any other age group, the percentages will be higher): 90% of vitamin B6, 97% of niacin, 67% of riboflavin, 40% of folate, and 64% of phosphorus. They are also full of beneficial minerals. One serving provides you with 64% of phosphorus, 37% of zinc, 20% of iron, 26% of potassium, and 20% of magnesium.
If you’re looking to increase your fiber, shiitake mushrooms are a tasty way to do it. One cup of cooked shiitakes provides 50% more fiber than a cup of bran flakes and almost twice the fiber as a cup of broccoli. However, the best part about shiitake mushrooms is that they are high in protein, very low in fat, and free of cholesterol. Who would have thought that one small serving of something so delicious could offer all of these nutritional benefits?
