mushrooms are a very common food on our dining table. Most mushrooms have a special fragrance, which is very delicious if you just make them simple.
And more importantly, mushrooms are not only delicious, but also healthy.
1. Why is mushrooms healthy?
has many studies have proved the various medicinal values of mushrooms. Among these medicinal values, has a substance called " mushroom polysaccharide ", which plays a great role.
Mushroom polysaccharide is a water-soluble proteoglycan extracted from the fruiting body of mushrooms (that is, the part we usually eat). It is generally believed that it can improve the body's immunity.
common "mushroom polysaccharides" include Agaricus bisporus polysaccharides, Brown mushroom polysaccharides, Brazilian mushroom polysaccharides, Bachu mushroom polysaccharides and purple mushroom polysaccharides. In addition, there is another star in the polysaccharide industry called shiitake polysaccharide , which has been made into an auxiliary anti-tumor treatment drug.

So how do these "polysaccharides" have the effect of regulating immunity?
These polysaccharides can: promote the formation of antibodies, such as shiitake polysaccharides, which can increase the production of peripheral monocyte antibodies in the human body; can induce interferon and inhibit tumor . For example, shiitake polysaccharides, Ganoderma lucidum polysaccharides, etc. have significant interferon induction and pro-induced induction effects; they can stimulate or assist in the recovery of T cells (T cells are an important part of the human immune system); can also stimulate cells with phagocytosis and enhance their phagocytosis function .
In particular, among these polysaccharides, there is a polysaccharide called "β-glucan", which is present in various edible fungi. It is an ingredient with very obvious immune enhancement effect. It can stimulate the body's immune system and serve as a carrier to make the value of other medicinal ingredients better.
Note: β-glucan is not only found in edible fungi, but also contains a lot of sugar in oats, beer yeast, barley and other foods. If you only want to supplement β-glucan, edible fungi, oats, and barley are all good sources.
2, other benefits of mushrooms
Mushroom is particularly good, that is, it does not contain cholesterol , and the levels of fat, sugar and sodium are low. It is rich in B vitamins, a variety of protein , fiber, and contains selenium, glutathione (can be antioxidant, has broad-spectrum detoxification and liver protection) and ergothionein (a natural antioxidant ).
Because mushrooms are free of cholesterol, low in fat content, and can antioxidant and enhance immunity. Moreover, the umami flavor contained in the mushroom itself can be used as a side dish to enhance the taste of the entire dish and increase the appetite of cancer patients, so for cancer patients, mushrooms are a food that is particularly suitable for rehabilitation.

Mushrooms can also replace staple foods: If people use 100 grams of mushrooms per meal instead of staple foods like fried rice and persist for a year, even if the diet structure does not change, they can consume 18,000 calories less, which is equivalent to two kilograms of fat. Patients who need to lose weight can give it a try.
However, there is a saying among mushrooms that it will absorb heavy metals and cause heavy metals to exceed the standard. People who eat mushrooms will be poisoned by heavy metals.
But the truth is actually this: some mushrooms have a higher ability to enrich heavy metals than green leafy vegetables, such as twin mushrooms. But first of all, mushrooms themselves do not contain heavy metal substances. If the growing environment is normal (such as artificially cultivated greenhouses), then it will not "adsorb" heavy metals, which will not cause heavy metals to exceed the standard.
The heavy metals consumed in the second place do not reach the dose that harms the human body, they will combine with the metallothrein and glutathione and other substances present in the body, and then slowly excrete them from the digestive tract.So there is no need to keep all the mushrooms out because of the heavy metal that "may exist". Of course, if you are still worried, you can just eat it in bulk.
