Will food be "mutual?

Recently, the "Food gram" notice board posted in a college canteen has been circulating on the Internet. The Notice states that the following food cannot be eaten at the same time within two hours, otherwise it may be poisoned or even at risk of life: crab and persimmon, Loach, eggplant, cantaloupe or peanut. It also provides detoxification recipes such as yellow mud water, incision, and citrus peel. I don't know why I only list crabs and other foods, and I doubt whether the canteen has special feelings for crabs. I am afraid everyone will eat more crabs.

This is only a small part of the widely used "Food gram" list. Although Chinese medicine denies that "food is related to Chinese medicine, there are many records in this regard in Chinese medicine classics. For example, "materia medica outline" has a section "food taboos", listing 180 million pairs of foods that cannot be eaten at the same time. Some of them are too ridiculous to know, and no one believes it, for example, "pork is not beef ". However, some of them are widely used, such as "crab and persimmon" and "green onion and Honey ". After I pointed out that there is no scientific basis for "food", it is just a kind of superstition that some people claim to have been poisoned or even killed after eating crabs, persimmons, onions and honey, and challenged me to say I dare to give it a try?

Of course I dare to try it. In fact, someone has already tried it. In 1935, it was a legend in Nanjing that the mixed eating of bananas and taro resulted in mutual food poisoning. This aroused the interest of biochemist Zheng ji. He collected 184 pairs of "Grams" of food and selected 14 combinations that are easy to meet in daily life, experiment with rats, dogs, and monkeys. He himself and a colleague also tried seven combinations. Observe the expression, behavior, body temperature, stool color and frequency of the animals and people in the experiment within 24 hours, and there are no signs of poisoning. In the "phase grams" Food of the Zheng ji test, it includes crabs and persimmons, scallions and honey. Zheng ji happened to be one of China's longest-lived scientists and was 110 years old.

Recently, the Chinese Nutrition Society has cooperated with the School of Public Health of Lanzhou University and Harbin Medical University to conduct more rigorous experiments on "Food gram. The experiment at Lanzhou University selects five groups of food combinations that are expected to be mutually exclusive, which were consumed by 100 healthy volunteers for a week without any exception. In the experiment of Harbin Medical University, another 12 groups of food groups were selected. 30 volunteers had been taking food for three consecutive days and no abnormalities were found. However, some volunteers thought that the combination of food was unreasonable, as a result, the taste is not suitable.

Although I have not tried all the legendary "Food grams", since none of the 31 groups have been selected, therefore, there is no reason to believe that the remaining uncommon combinations will become mutually compatible. Some people say that, even if I had eaten nothing at the time, will it cause chronic poisoning to my body? Traditional Chinese medicine classics and the so-called "food" have always referred to acute poisoning and even death immediately after eating, rather than chronic poisoning. The ancients can discover acute poisoning through experience, and cannot discover chronic poisoning. The chronic damage to the body caused by food is discovered by animal experiments, clinical trials, or epidemiological investigations, and the Ancients do not have this ability. Therefore, there is no reason to believe that "Food gram" will lead to chronic poisoning. It is also said that "Food gram" means that mixing different foods together may destroy the nutrients in the food. Of course, this possibility exists, but it is not the same as the traditional saying "mutual food". The Ancients cannot have this understanding. It is impossible to discover malnutrition caused by certain food.

However, some people are still convinced that the ingredients in different foods may have chemical reactions. Whether food ingredients can trigger chemical reactions must be specified and supported by experiments. Some people think that the reason for the "crab and persimmon grams" is that "the crab body is rich in protein, and it is easy to precipitate when combined with the Persimmon's Tanic Acid, and is solidified into a substance that is not easy to digest, due to the convergence of the acid, it can also inhibit the secretion of the digestive juice, resulting in the freezing substance stuck in the intestinal fermentation, it causes vomiting, bloating, diarrhea, and other food poisoning. "(according to a newspaper ). If the reason is true, persimmons are not only mutually gram with crabs, but also gram with other high-protein foods (such as meat, eggs, milk, even any protein-containing food may be mutually exclusive. In that case, persimmons may be in close contact with almost all food products. When eating persimmons, they cannot eat anything else. What's more, the "crab and persimmon" statement has been denied by the experiment and there is no need to make excuses for it.

Some "Food grams" have appeared in recent years. For example, "shrimp cannot be eaten with vitamin C (or juice rich in vitamin C ", the reason is that shrimp contains a high concentration of "Five-price arsenic compounds", which itself is not toxic to the human body, but Vitamin C will convert it into a highly toxic "Three-price arsenic ", that is, skin cream can cause acute poisoning and even death. Not long ago, a student died of myocarditis when eating at a Pizza Hut. His family claimed that the store was poisoned by the provision of shrimp and lemonade. In fact, the vast majority of arsenic contained in shrimp is stable organic arsenic, and the content of inorganic arsenic is very low (less than 4% ). According to national standards, the inorganic arsenic content per kilogram of shrimps cannot exceed 0.5 mg. Even if these inorganic arsenic can be completely reduced to arsenic (unlikely) by vitamin C, it would take up to 106 kg of the shrimp to reach the lower limit of oral arsenic death (70 mg, containing 53 mg of arsenic ), it is no longer poisoned, so it is no longer supported.

It is said that "food is similar" only in China. Foreigners have never had this idea and eat it casually (including pouring lemon juice to seafood). Isn't it too early to die? Do Chinese people have special bodies and food is only for Chinese people? Some foods have a certain degree of toxicity (such as toxic flower-brewed honey). Eating more food may cause digestive diseases (such as persimmons ), food may cause food poisoning after being contaminated by some bacteria. The ancients knew nothing about it. Once a certain food was eaten and then vomited and died, they would think about whether it was because of mutual food. The psychology of "better trust, less trust, and less trust" makes people afraid to take it lightly. Even if there is sufficient evidence of the opposite, they will still find excuses to continue to be superstitious, the food card is not that easy to pick.
