The Importance of Edible Medicinal Mushrooms and Their Potential Use as Therapeutic Agents Against Insulin Resistance.

In addition to conventional treatments, there is growing interest in preventive and complementary therapies. Proper nutrition can prevent the manifestation of several chronic diseases such as obesity, diabetes, cardiovascular disease, and cancer, and can attenuate the severity of these diseases. Edible mushrooms have been used as nutrition and medicine for thousands of years. The spectrum and quantity of their medicinal compounds made them a widely investigated target both in basic research and clinical trials. The most abundant and medically important components are polysaccharides, terpenoids, phenols, and heterocyclic amines, but bioactive proteins, vitamins, including vitamin D, polyunsaturated fatty acids, and essential minerals are also important ingredients with noteworthy health benefits. Mushroom extracts have anti-diabetic, anti-hyperlipidemic, anti-inflammatory, antioxidant, cardioprotective, anti-osteoporotic, and anti-tumor effects and are well tolerated, even by cancer patients. In our previous review we detailed the molecular aspects of the development of type 2 diabetes, discussing the role of physical activity and diet, but we did not detail the role of medicinal mushrooms as part of nutrition. In this review, we aimed to summarize the most important medical mushrooms, along with their natural habitats, growing conditions, and components, that are presumably sufficient for the prevention and treatment of insulin resistance.
