Role and consumption methods of shiitake mushrooms

Role and consumption methods of shiitake mushrooms, shiitake mushrooms are a kind of food often consumed in our life, which can be used to cook soup or stir-fried, but usually with other ingredients to cook. Shiitake mushrooms have a unique flavor, nutrition is also very rich, so what is the role of Shiitake mushrooms? What are the ways to eat them?

Mushroom anti-tumor effect

Shiitake mushrooms contain a variety of effective medicinal components, in particular, mushroom polysaccharide (LNT) has a certain antitumor effect. 1969 Japanese Chihara et al. separated and extracted LNT, and confirmed that the growth of S-180 sarcoma in mice has a significant inhibitory effect. In 1969, Chihara et al. isolated and extracted LNT and proved that it had obvious inhibitory effect on the growth of S-180 sarcoma in mice. Since then, many scholars at home and abroad have conducted a large number of more in-depth and diversified researches on the antitumor effect of LNT. In 1984, the U.S. Patent reported that by using xylose-rich solid medium to cultivate shiitake mushrooms, a kind of anticancer glycoprotein with xylose as the main component could be obtained from the mycelial culture. In China, Ou Huichun et al. isolated a glycoprotein from the solid culture of shiitake mushroom, whose anti-sarcoma 180 ` effect was 10 times better than mitomycin [6].A large number of pharmacological and clinical experiments on LNT were conducted after 1980's.Yao Yang et al. treated 80 cases of advanced malignant tumors with a combination chemotherapy regimen, and the results showed that: 43 cases of the combination of application of shiitake mushroom polysaccharides, the effective rate of 55.81%, while 37 cases of the combination chemotherapy alone, and 37 cases of the combination chemotherapy alone, the effectiveness rate of 55.81%. The effective rate of 43 cases with combined application of mushroom polysaccharide reached 55.81%, while that of 37 cases with combined chemotherapy without mushroom polysaccharide was only 35.14%, and the difference between the two groups was significant [7]. In the field of blood cancer research, Xie Xiaopeng et al. used shiitake mushroom polysaccharide with leukemia chemotherapy, which reduced the negative reaction of chemotherapy and increased the complete remission rate [8]. A large number of experiments have shown that mushroom polysaccharide is mainly involved in tumor therapy as an adjuvant drug, and has the effect of inhibiting and preventing postoperative micrometastasis in chronic granulocytic leukemia and many kinds of cancers, and this effect is indirectly toxic to the cancer cells through the immunity of the organism, which is especially suitable for the recovery of the organism after the disease. Compared with other anti-tumor drugs, LNT has almost no toxic side effects.

Shiitake mushroom enhances immunity

According to research, shiitake mushroom polysaccharides can activate macrophages, enhance macrophage phagocytosis, and increase the infiltration of neutral leukocytes into tumor nodes, which can promote the recovery of the host due to the imbalance of the body balance caused by cancer and infection. Shiitake polysaccharide can also increase the conversion rate of lymphocytes and enhance the anti-tumor ability of the body. After 16 days of intraperitoneal injection of shiitake polysaccharide into mice, the activities of acid phosphatase (ACP) and arginase in mice peritoneal macrophages were significantly increased, and the ability to damage tumor cells and inhibit the proliferation of tumor cells were significantly enhanced [9]. Dong Pujiang et al. studied the immunosuppressive factor produced by A549 human lung adenocarcinoma cells and the effect of mushroom polysaccharide on the transformation of T cells, and found that the transformation of T cells was inhibited by the immunosuppressive factor, and the degree of inhibition was positively correlated with the depth of the immunosuppressive factor, and the appropriate concentration of mushroom polysaccharide could effectively antagonize this inhibition [10]. Zhou Aiwu et al. found that shiitake polysaccharide could promote the generation of hemolysin antibody in splenocytes of cyclophosphamide-induced immunocompromised mice, and could also promote the proliferation of induced lymphocytes, enhance the number of splenic antibody-secreting cells and the formation of splenic-specific secretory cells [11]. It has been reported abroad that shiitake mushroom polysaccharide can activate T lymphocytes and promote the differentiation of many kinds of immature T cells to mature T cells [12]. At present, both at home and abroad, shiitake mushroom polysaccharide is regarded as the strongest restorer of helper T-cell activity and T-cell immune enhancer involving macrophages.

Shiitake mushrooms lower blood lipids, anti-thrombosis

It is found that both shiitake mushroom adenine and shiitake mushroom polysaccharides can promote the metabolism of cholesterol and reduce its content in serum, which has certain preventive and therapeutic efficacy for coronary heart disease, atherosclerosis, hypertension and other cardiovascular diseases. Shiitake mushrooms are rich in vitamins, and vitamins have the effect of lowering blood lipids and increasing coronary blood flow, and also have good preventive and therapeutic functions for hypertension and cardiovascular diseases. Japanese scholars have reported that each person consumes 90g of fresh shiitake mushrooms (or 9g of dried shiitake mushrooms) per day, and after a week of measurement of human serum cholesterol decreased by an average of 6% to 12%, thus making shiitake mushrooms a health food for people with high blood pressure.

Hepatoprotective effect of shiitake mushroom

According to the research, shiitake mushroom has certain efficacy in the treatment of acute and chronic liver diseases such as viral hepatitis, infectious hepatitis, cirrhosis of the liver, shiitake mushroom polysaccharides have a hepatoprotective effect and enhance the ability to detoxification, reduce the level of serum aminotransferases. Shi Yali et al. revealed that mushroom polysaccharides can significantly reduce the liver damage caused by CCl4 and other chemicals, stimulate the regeneration of part of the liver and resistance to various toxins in rats with resected livers, and at the same time, supplementation of mushroom polysaccharides increased the content of liver glycogen, which had a hepatoprotective effect.

In short, in addition to the better treatment of liver disease and cancer, shiitake mushrooms can effectively reduce blood lipids, enhance the body's immunity; thus effectively improve the physical fitness of people, so it is respected by the medical profession as a "health food", and some people refer to it as a "functional food". It is also called "functional food" by some people. With the rapid development of the economy, people's living standards continue to improve, the mushroom's international and domestic markets will be increasingly expanding, the demand for mushrooms and their processed products, health care products is rapidly increasing, mushroom products attractive prospects.

The role and consumption of mushrooms2

1, what is the role of mushrooms

Shiitake mushrooms are cold, slightly bitter taste, return to the liver, stomach meridian, has the effect of nourishing, can benefit the role of stomach to help food, for the qi and blood qi deficiency, intolerance of hard work and other deficiency of the constitution have a role in the conditioning. So it can regulate qi and blood deficiency syndrome.

In addition, when we pick mushrooms, we should pay attention to three look a touch: a look at the fungus benefit, to round, fat, under the volume, diameter 3-6 cm for the better, the second look at the fungal folds, to the rule of neat, not sticky slippery, no mold spots for the top, the third is the stipe, to the short and thick, uniform in size, the hand grip has a sense of firmness for the better; a touch, touch the hand to touch up the wet and sticky or press with the hand, it is not fresh. The first touch, the hand touched wet and slippery or pressed with the hand on the broken, is not fresh mushrooms, do not buy.

2, what are the practices of mushrooms

Mushrooms have a variety of practices, generally commonly used as a side dish for meat, the following to introduce:
