Mushrooms are fungal organisms like Ganoderma lucidum, Hericium erinaceus, Agaricus blazei, yeast and many other edible fungi. They all contain many different fungal polysaccharides. Fungal polysaccharides include (α, β, D) glucans, which have a variety of biological activities. It needs to be pointed out that generally people think that the precious Ganoderma lucidum has not been approved for consumption as ordinary food, and its safety has not yet been recognized by regulatory agencies. Studies have shown that long-term intake of sufficient fungal polysaccharides has health effects. In addition to adequate and long-term consumption, we must also pay attention to the intake of various types of fungal polysaccharides. The human body needs various physiological activities, and different types of fungal polysaccharides have different activities. Fungi are rich in fiber, polysaccharides, phenolic substances and alkaloids, which have anti-diabetic, anti-oxidant and anti-hyperlipidemic effects. A review article published in the International Journal of Biological Macromolecules detailed the mechanism of action of various active ingredients contained in different types of mushrooms in diabetes, and focused on the potential probiotics of mushroom polysaccharides by regulating the intestinal flora Meta role. The research results of the article are as follows: https://eu.echemi.com/info/fungal-polysaccharides-mushrooms-are-also-anti-diabetic_119276.html
