Scientific experiments have confirmed that there is no scientific basis for the argument that food is mutually exclusive. However, it is an objective fact and a normal phenomenon that nutrient interactions in food may affect absorption. Recently, it has been excavated by some "experts" as the theoretical basis of modern "food restriction".
Spinach and Tofu Many people have probably heard that "spinach and tofu" cannot be eaten together, because the oxalic acid in spinach will precipitate calcium in tofu, affecting calcium absorption; Some even said that "spinach and tofu can cause stones"! Indeed, spinach contains some oxalic acid, which will precipitate some calcium when eaten with tofu. However, if spinach is not eaten with tofu, the oxalic acid contained in spinach will precipitate the calcium contained in milk, rice and other foods. In other words, when spinach is combined with calcium from tofu, it will not be combined with calcium from other sources, so it is unnecessary to deliberately avoid eating the two foods together. In fact, less calcium absorption has no great impact on the human body. Originally, only 20%~40% of the calcium people ate could be absorbed, and most of the calcium was not absorbed, but was excreted with feces. When the experts set the dietary calcium requirement of 800 mg, they took into account the problem that most of the calcium could not be absorbed, and everyone did not need to worry about this problem when eating. As for the formation of stones, it is even more unreasonable, because calcium oxalate is not absorbed in the intestine, will not enter the circulatory system, and has nothing to do with the formation of stones in the body.
Shrimp and vitamin C It is also widely said that“

There is no food in the world that does not provide nutrition, and there is no food that provides all nutrition. Different foods have different nutritional characteristics. The difference is that some foods have more nutrients, some have less nutrients, some have more nutrients of this kind, and some have more nutrients of that kind. For example, sugar and B Vitamin B, protein and fat of legumes, minerals and vitamins of vegetables and fruits, high-quality protein and fat soluble vitamins of animal foods, etc. These foods are needed by the human body, and there is no good or bad food. adopt The choice of food by human civilization for thousands of years, a kind of food

Dear friends,
In 2008, I started my own blog under the guidance of Danone Nutrition Center, but stopped after writing a few paragraphs. Because of the time difficulties, I would not pretend to others. I always feel sorry to encourage my friends.
A while ago, I opened a microblog with the encouragement of my friends, and wrote several paragraphs, of course, with mixed praise and criticism. It's interesting to discuss some questions, but sometimes I feel I can't explain them clearly due to the limitation of the number of words.
Not long ago, when I was talking about the "Dietary Guide for Chinese Residents" on Sina. com, I was warmly encouraged by the people in charge of the blog, and suggested that I continue to write something. With the help of friends from Danone Nutrition Center, I found my login name and password, and planned to continue my long interrupted blog. I think I will spend some time in the future to discuss the food and nutrition issues that everyone is concerned about.

It seems that it is not our usual way to eat cucumber and yam together. I believe it is OK, but I have never eaten it. In order to answer the questions of netizens, I have to practice.
A yam was sold in the morning market on Sunday, washed, peeled and sliced in the afternoon. There are cucumbers in the refrigerator, take out one, wash and slice. Pour a little peanut oil into the pot, fry the chopped green onion and shredded ginger in the pot, put two pieces into the pot, mix them slightly, add salt and sugar to taste, put them on the plate and serve them. There is also a dish of peanuts, a tail of braised flatfish, and a bowl of cabbage, tofu, and dried rice soup.
As usual, I ate more than half of the Yanjing beer, a bowl of rice and fried cucumber with yam. Although not delicious, it is not difficult to swallow. After dinner, a cup of tea, reading, working, watching TV. He went to bed at 11:00 p.m., nearly 5 hours before dinner, and did not feel any discomfort. Get up at midnight and drink a little; Get up and go to the toilet the next morning, as always. So I assert: I have no adverse reaction after eating yam fried cucumber. Based on this, I speculate that many people will not have any adverse reactions after eating yam fried cucumber.
But I dare not say that you will be OK after eating, because people's physique is very complex, and our research is not enough. I have a friend in Qinghai who will have severe abdominal pain if he eats pineapple. Once, he accidentally ate pineapple in 'ancient meat', which made his intestines like a knife and made him sweat. Another friend in Dalian, only

Last time I said this sentence, I felt I should explain it again. Last year, Mei Chen, a freelance writer, visited me and talked about many issues. Two of them are related to the fact that eating is not so difficult. Copy as follows:
Mei Chen: Chinese people are accustomed to eating fried vegetables, From the perspective of nutrition, how should vegetables be eaten to be nutritious? Water blanching?
Ge Keyou: Not necessarily. The destruction of vitamins in vegetables is proportional to the temperature and heating time, so we don't advocate using very high temperature and long time to cook. Stir fry for a minute or two, and the vitamin loss in stir frying is not necessarily more than that in blanching; In the process of blanching, many nutrients will be lost to water, so there is no need to be so careful. If we say that people eat delicious and comfortable fried vegetables, they will eat half a jin of them; When cooking, everyone felt tasteless and didn't want to eat, so they only ate two liang; Which way takes more vitamins? Therefore, in principle, it is necessary to use less oil in cooking, and then master not too high temperature and too long time.
Mei Chen: In any case, whether it is stir frying or blanching, we have to destroy the nutrients and eat them crudely.
Ge Keyou: Eating raw has its advantages. For example, folic acid is easy to be absorbed when lettuce is heated. After heating, it loses a lot. This kind of food can be eaten raw; Like carotene and lycopene, it can be eaten raw, but it is easier to be absorbed by the human body after being heated and mixed with oil

Thank you for your kind words! For your questions, please forgive me that I can't answer them one by one. I can only say a few words in general. If you feel that I did not answer your question, that is, I will not answer your question. Please forgive me.
1、 Where can I get "balanced diet" information?
1。 The Ministry of Health issued the Dietary Guidelines for Chinese Residents on January 15, 2008 2007》。 This book was written by a nationally renowned expert entrusted by the Ministry of Health to the Chinese Nutrition Society. It was published by the Tibet People's Publishing House and distributed by the Xinhua Bookstore nationwide. The retail price is 28 yuan. This book is rich in content, scientific and easy to understand.
2。 Http://www.cnsoc. org, the website of the Chinese Nutrition Society, constantly publishes some short articles on diet and nutrition, which are generally discussed on a topic by topic basis and can be referred to.
3。 Dietary Guidelines for Chinese Residents The media interpretation board of "2007" is attached to the "Quota Popularization" section of the website of the Chinese Nutrition Society, which can be downloaded.
2、 How to eat?
In the past two years, there has been more talk about nutrition, more books, more articles in newspapers and magazines, more radio and television programs, and people don't know how to eat! What's the problem? The main reason is the imbalance of information. Each speaks his own way, which is often one-sided and even contradictory.
In fact, eating is not that difficult.
To live a healthy life, we must rely on adequate and reasonable food. Every kind of food contains certain nutrients, and no one food can provide all the nutrients our body needs. If a food has no nutrition, then people will not call it "food". After thousands of years of elimination, our ancestors chose to keep the food, which has certain nutritional value.
Different foods have different nutritional advantages or characteristics. For example, sugar and B vitamins in cereals, protein and fat in legumes, minerals and vitamins in vegetables and fruits, high-quality protein in animal foods, etc. These foods are all what we need. You can't say which is good or which is bad. Only by properly matching all kinds of food can we guarantee the quality and quantity of sufficient and comprehensive nutrition for the human body, which is called "balanced diet".
Don't believe that "certain food is particularly good", "certain food is particularly bad", "what food can't be eaten" "What is the best food", etc. If someone eats a large bowl of braised pork every day and gets heart disease, you can't say that the meat is bad, only that you eat it unreasonably. Because the initiative of eating is in our own hands.
The "Dietary Guidelines for Chinese Residents" and "Balanced Dietary Pagoda" formulated by the Chinese Nutrition Society are based on this principle to popularize scientific knowledge and guide consumers to integrate

I have already settled down in Sina Blog. You are welcome to "come and have a look". I am now the president of the Chinese Nutrition Society. It is an important task for our Nutrition Society to publicize nutrition knowledge, and I also regard it as my personal responsibility. For this reason, as the chairman of the two sessions of the scientific committee and the current vice chairman of Danone Nutrition Center, at the invitation of Danone Nutrition Center, I set up my own real name blog here to publicize nutrition knowledge to the public and provide consulting services for the public. Welcome to visit my blog and leave your questions about nutrition in my blog. I will try my best to arrange time to answer your questions. For this reason, I specially invited the staff of our Nutrition Society Chang Chaohui came to help me manage this blog. I would like to express my heartfelt thanks to her!
For our nutrition professionals, we are very willing to share our personal knowledge with you. We should not only engage in research and publish academic papers, because the masses need this nutrition knowledge, so I also call on all professionals engaged in nutrition and health to contribute your knowledge, give back the knowledge to the masses, provide the masses with scientific basis of nutrition knowledge, and benefit the health of the masses. Otherwise, there will be unscientific so-called nutrition knowledge spreading everywhere, which will harm the public's health.
I will just one
