Mushrooms are a low-calorie food that packs a nutritional punch. Loaded with many health-boosting vitamins, minerals, and antioxidants, they’ve long been recognized as an important part of any diet. For instance, mushrooms are an excellent source of vitamin D, an important component in bone and immune health. Cremini mushrooms are a particularly excellent source of zinc, an essential trace element. Zinc is a vital nutrient for the immune system and is also needed for ensuring optimal growth in infants and children.
