Some time ago, it was called "the first dietotherapy person in China". Besides mung beans, there are eggplant. It is said that eating raw eggplant can reduce weight and blood fat. His theory is that eggplant can absorb oil especially, so it needs to add more oil than other vegetables when frying eggplant. After eating raw eggplant, you can absorb a lot of oil in the gastrointestinal tract when you enter the body, so eating raw eggplant must have the effect of losing weight and lowering blood fat. This is actually not the invention of this criticized "health master". Earlier than him, a chief health education expert of the Ministry of Health who often introduced the secrets of traditional health preservation in newspapers and periodicals and the director of the trace elements research office of a large hospital also advocated eating eggplant raw for the same reason: "Eggplant is healthy if eaten raw or steamed with vinegar and garlic. Because eggplant has a strong function of absorbing fat, it has the ability to lower blood lipids and cholesterol. " Therefore, there is not much difference between the official "health education expert" and the self-styled "health master". Fried eggplant is easy to absorb oil, not because eggplant contains special substances that can absorb fat, but because eggplant has a porous sponge-like structure. However, once the eggplant is chewed and digested, the spongy structure disappears and it is impossible to absorb oil. Even if it can absorb the oil in the gastrointestinal tract, the intestine can absorb the oil into the body. Therefore, it is only an illusion that eggplant can absorb a lot of oil in the gastrointestinal tract. Otherwise, isn't eating sponge better for absorbing oil, losing weight and lowering blood fat? However, judging from the fact that fried eggplant is easy to absorb oil, eggplant can also absorb body fat, which is quite in line with the idea of "complementing shape with shape" and "comparing images with classes" in China traditional medicine. Unfortunately, the ancients didn't know about blood lipids and were not afraid of obesity, so this statement can't be found in ancient books. Otherwise, the "master of health preservation" can quote classics to defend himself. Unlike mung beans, the ancients did not pay much attention to the medicinal use of eggplant, and even said that eggplant was useless in vegetables, and eating too much also hurt the body. Compendium of Materia Medica only says that eggplant can "promote blood circulation and relieve pain, reduce swelling and moisten intestines", and has collected more than a dozen prescriptions, some of which look amazing. For example, there is a secret recipe for treating "eggs (testicles) falling off": hang double-pedicled eggplant on the door and stare at it when entering and leaving. When the eggplant wilts, the affected area will wither and the eggplant will dry up. Isn't it amazing that you can cure diseases without touching them? This is probably due to the association of double-pedicled eggplant shaped like an egg, which is not so much medical skill as witchcraft. In fact, eating eggplant to reduce cholesterol was introduced from abroad, and it was given a unique explanation by the "health master" in China. In theory, eating more eggplant can lower cholesterol, not because eggplant contains any special magical substances, but because eggplant has higher cellulose content. Cellulose cannot be digested and absorbed. When they pass through the small intestine, they can combine with cholic acid there. Cholic acid is synthesized by cholesterol in the liver, transported to the gallbladder, and then secreted into the small intestine to dissolve fat and cholesterol in food. Cellulose takes cholic acid away from the small intestine and eventually excretes it as a component of feces. This forces the liver to synthesize new cholic acid from cholesterol, which reduces the cholesterol content in the body. As long as you eat cellulose, you can also have the same cholesterol-lowering effect, not just eggplant. There are many vegetables with high cellulose content, so there is no need to eat eggplant specially for this purpose. Some people abroad think that eggplant has other special substances that can lower cholesterol. For example, it is popular in Brazil to peel and chop eggplant and mix it with orange juice. Drinking a cup every morning is thought to lower cholesterol by 30%. However, Brazilian researchers did a controlled experiment and found that there was no difference in cholesterol content between people who drank this homemade drink every day and the control group. If you eat eggplant for fiber intake, it is the same as eating it raw and cooked. Most people are not used to eating raw eggplant, because raw eggplant has bitter taste, which is because eggplant contains several solanine. Solanine is a natural insecticide and a toxin harmful to human body. Excessive intake can lead to poisoning and even death. If a person weighing 60 kg ingests 60 mg solanine, he may start to have symptoms of poisoning (gastrointestinal discomfort), 105 mg may have symptoms of acute poisoning, and 180 ~ 360 mg may be fatal. Solanine is relatively stable, insoluble in water and resistant to high temperature. Boiling can only destroy a little toxicity, and frying at high temperature can effectively remove the toxicity of solanine. The content of solanine in eggplant varies greatly, generally not exceeding 5 mg/100 g, so eating more than 1 kg of eggplant may cause poisoning. Therefore, it is generally impossible to eat too much eggplant poisoning at one time. However, after entering the human body, solanine will be stored in most organs and soft tissues, and only a little will be excreted every day. If you eat eggplant every day, even if you don't reach the amount of poisoning every time, you may be poisoned by the accumulation of toxins in your body. If you eat other foods containing solanine (such as potatoes), you are more likely to be poisoned. Recently, newspapers all over the country reported that some people ate eggplant raw every day and got enteritis as a result. It is precisely because they listened to the words of the "health care master" and lacked scientific knowledge that "health care" finally became "harmful".
