1. Edible fungi are characterized by high protein, low fat and rich in vitamins and minerals, which are very suitable for middle-aged and elderly people. For example, the protein content of 500g mushrooms is equivalent to 1kg lean meat or 1.5kg eggs. In particular, edible fungi not only contain eight essential amino acids, but also are rich in lysine and leucine, which is very helpful for middle-aged and elderly people to delay memory decline and enhance intelligence.

2. Edible fungi can lower cholesterol and blood sugar. Take Lentinus edodes as an example, it contains an organic substance called Lentinus edodes adenine, which can significantly lower cholesterol. Recent studies have found that many kinds of edible fungi have low sugar content and hypoglycemic effect, which are suitable for patients with type II diabetes and are often listed as the first choice food.

3. Edible fungi help to regulate immunity and fight cancer. It is reported that the active polysaccharides contained in Ganoderma lucidum, Auricularia auricula, Tremella, Cordyceps sinensis, mushrooms and Hericium erinaceus have anti-tumor effects, mainly by enhancing their immunity. Therefore, it is generally believed that edible fungi are non-specific immune enhancers with two-way regulation.

4. Edible fungi have the functions of scavenging free radicals and resisting aging. Metallothionein contained in edible fungi has a strong free radical scavenging effect, thus delaying cell aging.
