Today the market is becoming richer and richer in flavorings, and there are many brands of chicken essence. Some people say that in the additives, only MSG is harmless and very nutritious, and even to be more. But do you know, MSG, chicken essence is harmful to the body, serious and even fatal. Remind those who love to eat chicken, MSG friends, must pay attention to slowly reduce the amount of consumption! The invention of MSG In fact, there was MSG in ancient times. In fact, MSG existed in ancient times, but it was called seaweed powder instead of monosodium glutamate. During the Ming Dynasty, Chinese cooks used a kind of seaweed powder as a seasoning, adding it to their dishes to give them a strong flavor. It wasn’t until 1908 that Dr. Kikuyo Ikeda, a professor at the University of Tokyo, discovered that the glutamate salt contained in this seaweed powder was the secret to the richness of the food’s flavor. So he extracted this chemical and formed crystals called Ajinomoto, which we in China call MSG. Japanese businessmen immediately took this discovery to make money, and the next year MSG was on the market. Who Discovered MSG Was Harmful An American doctor, after eating at a Chinese restaurant in New York, felt paralysis in his body, starting at the back of his neck and extending to his arms and back and buttocks, and at the same time, he felt weakness in his whole body, and his heart beat fast, and these symptoms lasted for about two hours. This doctor realized that many of his friends had similar symptoms after eating Chinese food. So he wrote a letter to an American medical journal about it. After his letter was published, many people wrote in with similar experiences, some suggesting that the symptoms might have been caused by MSG. Yes, Chinese restaurants use a lot of MSG for flavor. These symptoms are known as Chinese Restaurant Syndrome. Several doctors and scientists have conducted tests and found that some people develop Chinese Restaurant Disease when they eat food containing MSG. Since then, Chinese Restaurant Disease has become a serious concern for some Westerners. Some people are particularly sensitive to MSG, for example, some asthmatics’ condition worsens after eating MSG. There will be a variety of Chinese restaurant disease, and then after 12 to 14 hours will have an asthma attack, some asthma patients because of the seriousness of the situation and have to be sent to the hospital rescue, if not timely treatment, may die. Australian doctors have also treated some asthma patients who were admitted to the hospital with acute illnesses in this way. Chinese restaurant syndrome, as well as Chinese restaurant asthma, is independent of the weight of MSG consumed; it can occur whether 6 grams or 1.5 grams are consumed daily. Symptoms of acute MSG poisoning are facial congestion, hot or burning sensation, swollen tongue; abnormal or accelerated heartbeat, dizziness, headache, migraine, stiff neck, muscle contractions, nausea, insomnia, gastrointestinal discomfort; tingling of the skin, neck, arm, and chest pains; upper extremity tenderness and depression; worsening of asthma; and coughing. Chronic MSG poisoning can lead to the following situations: impede fetal development, so that the offspring deformed American scientists in a rabbit experiment, the rabbits are divided into four groups. The first group of rabbits 10 females and 4 males, all the female rabbits ate 25 milligrams of MSG per kilogram of body weight for 27 days, while the male rabbits do not eat. The females later became pregnant; two females had metamorphic fetuses in utero and later miscarried, giving birth to deformed stillborns; the other two later became pregnant and gave birth normally, but the young rabbits had multiple deformities in their limbs and growth retardation. A second group of rabbits, four females and two males, all ate 25 mg of MSG per kilogram of body weight. Two females became pregnant and produced deformed bunnies, both of which died shortly after birth, with skeletal deformities and multiple organ atrophy. A third group of rabbits, six females and one male, all ate 25 mg of MSG per kilogram of body weight. The males had atrophied testes and the females gave birth to rabbits with multiple mutilations. A fourth group of rabbits, 6 females and 8 males, served as a control; none of the above occurred due to the absence of MSG. Destruction of genetic factors, affecting fertility, and can not be seen at a young age American scientists in 1970 and 1971, and 1975, three mouse experiments found that if the female mice ate MSG, then the pups have grown up to endocrine disruption. These three experiments also found that mice were injected with MSG equivalent to 2.2 to 4.2 grams per kilogram of body weight by subcutaneous injection for 10 consecutive days shortly after birth, and then killed at 40 days old for autopsy, which revealed that these mice had reduced body weight, necrosis of testes and ovaries, reduced weight of adrenal glands and thyroid glands, and reduced levels of growth hormone and luteinizing hormone in the pituitary gland of the anterior cerebrum. As a result, mice of both sexes grew up with reproductive problems: females had fewer pregnancies and produced particularly small mice; males were also much less fertile. Aggravate allergic rhinitis, aggravate allergic asthma Chinese doctors found that many patients with allergic rhinitis, allergic asthma, after stopping the consumption of monosodium glutamate (MSG), the symptoms of their healing. Lead to obesity American scientists in 1970 in an experiment, a group of rats in the first 10 days after birth with a subcutaneous injection of MSG into the body, the results of growing up have been demented fat – epididymal fat pads increase in weight, cell volume increases, the number of adipose plasmacytoid cells decreased. In addition, when these rats were compared to a control group, the larger cells in their bodies were particularly unresponsive to the lipolytic effects of adrenaline, but were particularly responsive to the anti-lipolytic effects of insulin. The experts in charge of the study believe that MSG contributes to obesity because it alters the cellular response to adrenaline and insulin, increasing the lipid content of the fat mass. In a 1974 experiment, American scientists found that young rats fed a diet containing 1% to 2% MSG for a long period of time weaned at a higher weight than the control group. In a 1997 experiment, a group of rats in the first 10 days after birth with peritoneal injection into the equivalent of 4 grams per kilogram of body weight of monosodium glutamate (MSG), the results were found to grow up malformed, endocrine anomalies, behavioral anomalies, most of which the tail is automatically split, all the obvious and short and dementia, female rats than the control of the other group of ovary, uterus, pituitary gland is small. Another group of rats were also injected with the same amount of MSG in the first 10 days after birth, but in five injections, resulting in much less of the typical MSG damage described above. Permanent Brain Trauma American scientists in 1970 in a rat experiment, 65 10 to 12 days old rats, a one-time feeding of different amounts of MSG, including 0.5 grams per kilogram of body weight, 0.75 grams per kilogram of body weight, 1.0 grams per kilogram of body weight, 2.0 grams per kilogram of body weight, of which 10 did not eat MSG, as a control. 3 to 6 hours after feeding, all the rats killed by perfusion, it was found that 54 rats ate MSG, 51 rats brain nerve cells have necrosis, and the rate of necrosis is exactly proportional to the amount of MSG service. The experiment also found that if MSG and saccharin are eaten together, brain damage is doubly serious. Damage to the retina, affecting vision In a 1960 experiment, American scientists used peritoneal injection method, the MSG into the body of young rats, the amount of 3.2 grams per kilogram of body weight, the results found that those rats retinal toxicity damage. In an experiment in 1967, American scientists in a group of rats 1 ~ 10 days after birth, with parenteral injection of the equivalent of 2.2 ~ 4.2 grams per kilogram of body weight of monosodium glutamate (MSG) 10 times into the body, the results of the retina is completely destroyed. In 1969 an experiment, some 1 to 10 days old rats were a subcutaneous injection of 4 grams of MSG per kilogram of body weight, and then were killed after 30 minutes to 48 hours, the results found that the retina is severely damaged – everywhere there are nerve branching protrusions, and nerve cells gradually necrosis.
