Persimmon+crab = diarrhea poisoning
Spinach+tofu = stone
Seafood+fruit = eating arsenic
……
Many people have always believed that "food equals grams" and even printed out a "food equals grams" and posted it at home.
After 85 years of gossip,
Others believe that "food is like grams"!
165438+1October 26th CCTV news reported that it was not only in recent years that the rumor that "food is similar to food" was refuted. As early as 1935, Professor Ji Zheng, a scientist in China and the founder of China Nutrition Society, chose "food similar to food" which was widely circulated among the people in 184.
①
CCTV 3 15 party 20 18 also refuted the statement that "food is like grams". Experts take crabs and persimmons as examples to show that crabs and tomatoes are in human gastric juice, and arsenic in crabs will not be converted into arsenic. Paying too much attention to cannibalism will affect the diversity of food we eat, and the rumor that "food cannibalism" is untenable.
Rumors about food will always spread regularly. Every season, there will always be some rumors that have been circulated before, and they will be put on new vests and heated up. The saying that "food is like grams" has been repeatedly refuted, but many people just believe it!
Experiments prove that:
Food is nonsense!
In fact, the experiment published in the Health Times on August 201/2008 confirmed that the saying that "food is like grams" is nonsense! ②
Rumor 1
1935, there was an epidemic in Nanjing, which was thought to be caused by food cannibalism. It is said that bananas and taro can't be eaten together. There is something wrong with eating them.
Experimental research:
Ji Zheng, a professor of biochemistry at Nanjing University at that time, experimented with mice, monkeys and dogs and chose seven pairs of foods that people often eat. He ate with two colleagues for two days, but nothing happened. His food experiments include: green onions and honey, sweet potatoes and bananas, preserved eggs and sugar, peanuts and cucumbers, green beans and caramel, kelp and pig blood, persimmon crabs and so on.
Proverbs 2
During the five years from 2003 to 2008, there were 6 1 book on food compatibility, and there were 159 articles on food compatibility, of which 5/6 were about food compatibility.
Since 2009, China Nutrition Society has selected 100 healthy people, and selected some foods that people often eat, including lily pork, sesame diced chicken, potato beef, pork liver fried green pepper, soybean spinach, fruit kelp and so on. After eating for a week, there is no so-called poisoning, gastrointestinal dysfunction, indigestion, diarrhea and so on.
Eating several foods together can be problematic,
What's going on here?
If there is no "food compatibility", then why are some foods uncomfortable to eat together? Give a few common examples:
1. Persimmon+crab = diarrhea poisoning?
According to the saying that "food is like grams", persimmon mixed with dairy products, seafood and other foods can easily lead to diarrhea poisoning. However, Li Cheng, a postdoctoral fellow at Beijing Institute of Nutrition Sources, told CCTV News that the problem is not that persimmons are mixed with other foods, but that dietary fiber contained in persimmons can promote intestinal peristalsis. Some people with sensitive intestines may have diarrhea after eating a lot of persimmons. ?
2. Seafood+fruit = eat arsenic?
Arsenic trioxide, chemical name The nutrient composition table shows that there are trace arsenic in seafood such as shrimp and crab, but it is mainly harmless organic arsenic, which will be basically excreted intact after intake. When arsenic contained in shrimp and crab is combined with vitamin C in fruit, arsenic trioxide, which is arsenic, will be produced. But experts say that if you want to reach the toxic dose, you may need to eat 300 kilograms of shrimp at a time. ?
3. Spinach+tofu = stone?
According to the theory of food compatibility, the combination of spinach oxalic acid and tofu calcium into calcium oxalate is not absorbed, but milk also contains calcium, which will combine with milk in gastrointestinal tract. Drinking soybean milk also contains calcium, and many foods we eat contain calcium ...?
4. Watermelon+peach = toxic?
This is also fake. Eating too much high-sugar food can easily lead to diarrhea in people with poor stomach, which is actually related to the permeability of sugar. In addition, the water content of watermelons and peaches is very high, which leads to excessive water in the stomach and easy diarrhea. People with poor gastrointestinal function are prone to diarrhea after eating a lot of two kinds of fruits. ?
5. Honey+tofu = deafness?
Some people say this because they think that honey contains a small amount of organic acids, which can react with protein in tofu to form flocs that are not easily absorbed by the human body. Yan Zhihua, a nutritionist, said in China WeChat official account number 20 16 that this kind of floc is actually the product of protein decomposition, but its fluffy structure is more conducive to protein's digestion and absorption. ?
6. Durian+milk = fatal?
This myth stems from the news that "tourists eat durian and milk to produce caffeine, which leads to soaring blood pressure and death in other places". Durian and milk can be eaten together and will not produce caffeine. However, nutritionist Yan Zhihua said that durian is delicious, but enough is enough, because durian contains a lot of sugar and high fat, which is easy to cause indigestion and other reactions. ?
To sum up, there are three main reasons for the emergence of the theory of "eating the ancient":
1. Cognitive limitations:
People's experiences in history should be recorded and passed on to future generations. Someone ate green onions dipped in honey and had a terrible stomachache. At that time, doctors knew nothing about surgery and infection. When looking for the reasons from the symptoms, they found that their diet was improper-the saying that green onions dipped in honey were "mutually gram" was handed down. According to modern medical knowledge, this symptom may be acute appendicitis, which has nothing to do with onion honey.
2. Food pollution:
I didn't know about food pollution before, so I had diarrhea after eating cucumber and scrambled eggs. Some people say that these two can't be eaten together. In fact, the ingredients may be contaminated.
3. Allergy:
Many people feel itchy, swollen and allergic when they eat seafood. This is a special constitution. It happened that this example was also recorded. It turns out that prawns and fruits can be poisoned when eaten together. In fact, some people are allergic to seafood.
How on earth should we eat?
How should I eat? Nutrition is generally balanced, so don't worry too much. Ge You Ke, honorary chairman of the China Nutrition Society, shared his views in the August Health Times 20 1 1:
Don't think that you can't eat this and that. How many grams do the dietary guidelines require you to eat? Do I have to weigh myself before eating every day? The food you eat in a week is generally balanced, so it's ok.
Ordinary people don't have to worry. This is nutritious. Please check the nutrient composition table as soon as possible. How to eat? It's too thin, it's unnecessary. Never mind the details, eat well and live happily, that's it!
