The functions and eating methods of shiitake mushrooms
The functions and eating methods of shiitake mushrooms. Shiitake mushrooms are a kind of food that is often eaten in daily life. They can be used to cook soup or stir-fry. However, it is usually cooked with other ingredients. Shiitake mushrooms have a unique fragrance and are rich in nutrients. So what are the functions of shiitake mushrooms? What are some ways to eat it?
The functions and consumption methods of Lentinus edodes 1
The anti-tumor effect of Lentinus edodes
Lentinus edodes contains a variety of effective medicinal components, especially lentinan (LNT). Certain anti-tumor effects. In 1969, Japanese Chihara et al. isolated and extracted LNT, and confirmed that it had a significant inhibitory effect on the growth of mouse S-180 sarcoma. Since then, many scholars at home and abroad have conducted a large number of more in-depth and diversified studies on the anti-tumor effects of LNT. In 1984, a U.S. patent reported that a solid medium rich in xylose was used to cultivate shiitake mushrooms, and an anti-cancer glycoprotein containing xylose as the main component could be obtained from the mycelium culture. my country's Ou Huichun and others isolated a glycoprotein from the solid culture of Lentinus edodes, and its anti-sarcoma 180 effect is 10 times better than mitomycin [6]. In a large number of pharmacological and clinical experiments on LNT after the 1980s, Yao Yang et al. used combined chemotherapy regimens to treat 80 cases of advanced malignant tumors. The results found that 43 cases were combined with lentinan, with an effective rate of 55.81, while 37 cases were treated with combined chemotherapy alone. For chemotherapy, the effective rate of the control group without lentinan was only 35.14, and the difference between the two groups was significant [7]. In the field of blood cancer research, Xie Xiaopeng and others used lentinan to combine with leukemia chemotherapy, which reduced the negative reactions of chemotherapy and improved the complete remission rate [8]. A large number of experiments have shown that lentinan is mainly used as an auxiliary drug to participate in tumor treatment, and has the effect of inhibiting and preventing postoperative micro-metastasis on chronic myelogenous leukemia and various cancers. This effect is indirect toxicity to cancer cells through the body's immunity. Especially suitable for physical recovery after illness. Compared with other anti-tumor drugs, LNT has almost no toxic or side effects.
Lentinus edodes enhances immunity
According to research, lentinan can activate macrophages, enhance macrophage phagocytosis, and increase the infiltration of neutrophils into tumor nodules, prompting the host to Restoration of homeostasis disorders caused by cancer and infection. Lentinan can also increase the transformation rate of lymphocytes and enhance the body's anti-tumor ability. Sixteen days after intraperitoneal injection of lentinan into mice, the activity of acid phosphatase (ACP) and arginase in peritoneal macrophages of mice increased significantly, and the ability to damage tumor cells and inhibit tumor cell proliferation were significantly enhanced [ 9]. Dong Pujiang et al. studied the impact of immunosuppressive factors produced by A549 human lung adenocarcinoma cells and lentinan on T cell transformation and found that: T cell transformation is inhibited by the immunosuppressive factor, and the degree of inhibition is positively correlated with the depth of the immunosuppressive factor. Lentinan at an appropriate concentration can effectively antagonize this inhibitory effect [10]. Zhou Aiwu et al. found that lentinan can promote the production of hemolysin antibodies in spleen cells of mice with low immune function induced by cyclophosphamide. It can also promote the proliferation of induced lymphocytes in mice and enhance the number of spleen antibody-secreting cells and spleen-specific secretory cells. formation [11]. Foreign reports indicate that lentinan can activate T lymphocytes and promote the differentiation of various immature T cells into mature T cells [12]. At present, lentinan is regarded both at home and abroad as the strongest restorer of helper T cell activity and a T cell immunity enhancer involving macrophages.
Lentinus edodes lowers blood lipids and resists thrombosis
Studies have found that lentinus adenine and lentinan can promote cholesterol metabolism and reduce its content in serum, which is beneficial to coronary heart disease, arteriosclerosis, Cardiovascular diseases such as hypertension have certain preventive and therapeutic effects. Shiitake mushrooms are rich in vitamins, which can lower blood lipids and increase coronary blood flow. They also have good preventive and therapeutic functions for hypertension and cardiovascular and cerebrovascular diseases.
Japanese scholars have reported that if each person eats 90g of fresh shiitake mushrooms (or 9g of dried shiitake mushrooms) per day, the human body's serum cholesterol will drop by an average of 6 to 12% after one week, making shiitake mushrooms a health food for patients with hypertension.
The hepatoprotective effect of shiitake mushrooms
According to research, shiitake mushrooms have a certain effect on the treatment of acute and chronic liver diseases such as viral hepatitis, infectious hepatitis, cirrhosis, etc. Lentinin has a hepatoprotective effect. And enhance detoxification ability and reduce serum aminotransferase levels. Shi Yali et al. revealed through the mouse exhaustion experimental model that lentinan can significantly reduce liver damage caused by chemicals such as CCl4, stimulate partial liver regeneration and resist various toxins in liver-removed mice, and supplement lentinan to improve liver function. The glycogen content has a liver-protective effect.
In short, in addition to its good function in treating liver disease and cancer, shiitake mushrooms can effectively reduce blood lipids and enhance human immunity; thus effectively improving people's physical fitness. Therefore, it is highly praised by the medical community It is a "health food", and some people call it "functional food". With the rapid development of the economy and the continuous improvement of people's living standards, the international and domestic markets for shiitake mushrooms will increasingly expand. The demand for shiitake mushrooms, their processed products, and health care products is increasing rapidly, and the prospects for mushroom products are attractive.

1. What are the functions of shiitake mushrooms?
Shiitake mushrooms are cold in nature and slightly bitter in taste. They belong to the liver and stomach meridian. They have health-preserving effects and can benefit the stomach. It acts as a food aid and regulates weak constitutions such as deficiency of qi, blood, and intolerance to fatigue. Therefore, it can regulate Qi and blood deficiency.
In addition, when we choose shiitake mushrooms, we should pay attention to three things: look at the benefits of the mushrooms, which are round, thick, rolled down, and 3-6 cm in diameter; secondly, look at the gills. , the top quality should be regular, non-sticky, and free of mildew. The third is the stipe, which should be short and thick, even in size, and feel hard when held in the hand; when touched, it will feel moist and slimy to the touch, or it will feel wet and slimy with the hand. If they break when pressed, they are stale mushrooms. Do not buy them.
2. What are the ways to prepare shiitake mushrooms?
