Bean curd contains soybean isoflavone, which has the functions of antioxidation, inhibiting tumor cell growth, dilating blood vessels and inhibiting platelet aggregation. Secondly, soybean lecithin contained in tofu has the function of blood vessel scavenger, which can inhibit the deposition of cholesterol on the blood vessel wall and remove the sediment, thereby reducing cholesterol and blood viscosity, and finally preventing cardiovascular and cerebrovascular diseases. Moreover, tofu contains soybean oligosaccharides, which can promote the proliferation of bifidobacteria in the intestine, facilitate defecation and maintain the health of the intestine, increase the immunity of the body, and prevent colorectal cancer and diabetes.
For all people, no one can eat tofu forever. For some people with special physique, it may be necessary to reduce the intake of tofu appropriately.
What are the benefits of eating beans (tofu)? In recent years, some large-scale clinical studies have also confirmed this point. Let's see what's good about eating tofu.
1. Eating more tofu can reduce the risk of cardiovascular and cerebrovascular diseases: Clinical trials of 200,000 people have proved that increasing the intake of isoflavones (such as tofu) can reduce the risk of coronary heart disease. Compared with men, the relationship between eating tofu and coronary heart disease is more obvious in women, especially young premenopausal women and postmenopausal women who have not used hormones!
2. Eating more tofu may reduce the risk of breast cancer: tofu contains soybean isoflavones, which are similar in structure to estrogen molecules, so it can show weak estrogen activity in the case of insufficient estrogen in women, and can be used to prevent and treat female menopause syndrome.
Among 6235 breast cancer patients, the study found that the intake of bean food (tofu) was negatively correlated with death, and the risk of all-cause death of female patients with negative estrogen receptor/progesterone receptor and without estrogen treatment was reduced, which was significantly related to the high intake of progesterone.
Tofu is nutritious and everyone can eat it. But for some patients with special physique or diseases, it is necessary to reduce the intake of tofu according to their physical condition.
1. Gout patients should eat less: Tofu contains purine, and patients with acute gout should eat less or even not, so as to avoid further aggravation of gout. For gout patients with abnormal purine metabolism and patients with elevated blood uric acid concentration, we should also eat less tofu to avoid gout.
2. Patients with iodine deficiency should eat less: Soybeans that make tofu contain a substance called saponin, which can not only prevent atherosclerosis, but also promote iodine excretion in the human body. It will not have much influence on normal people, but for iodine deficiency patients, eating tofu in large quantities for a long time may further aggravate the symptoms of iodine deficiency, so it is recommended that iodine deficiency patients eat less.
3. People with bad stomachs should eat less: tofu is cold. If the stomach is not good, symptoms such as abdominal distension, stomach acid or nausea may appear after eating tofu, so eat less. If the spleen and stomach are deficient in cold, diarrhea and abdominal distension often occur, it is not recommended to eat too much tofu.
4. Patients with renal insufficiency should eat less: patients with renal insufficiency have decreased renal excretion capacity. If you eat too much tofu, it may lead to too much nitrogen-containing waste in your body, resulting in excessive burden on your kidneys and further decline in renal function.

In addition, if your family members have related questions, please pass this article on to them! Tofu is nutritious, rich in high-quality plant protein, unsaturated fatty acids, vitamin E, calcium, soybean isoflavones, dietary fiber and so on. And beans are rich in protein lysine, which can complement protein and improve the nutritional value of protein when eaten together with cereal staple food.
Traditional brine tofu is especially recommended. The existence of this alkaline coagulant can improve the digestibility of protein, because it reduces or removes the anti-nutritional factors such as phytic acid and tannin in raw materials, and is also more conducive to calcium supplementation.
Nutritional advantages of tofu
Rich dietary fiber not only helps to control blood sugar, but also helps to lose weight and prevent obesity;
* Unsaturated fatty acids rich in tofu have the function of protecting cardiovascular system;
* Tofu has a high calcium content, which helps to maintain bone health, especially suitable for middle-aged and elderly people who don't like to drink milk.
Who is not suitable for tofu?
Although tofu is nutritious and delicious, some friends are not suitable or should eat less.
1. Patients with diabetic nephropathy
Diabetic nephropathy 1: You can still eat soy products if you want, but it should be strictly restricted. It should not exceed 10 15 grams of bean products or the same amount of bean products every day, and the tofu brain is about one or two. Be careful not to overdo it, and pay attention to going to the hospital regularly to check renal function, urinary microalbumin and urinary protein.
Diabetic nephropathy stage 2 and above: it is recommended not to eat soy products.
2. Patients with hyperuricemia and gout
20 1 1 A review published in Asia Pac J Clin Nutr mentioned a survey, and 48% of medical staff also thought that bean products could cause gout. However, this is not the case.
Tofu contains less than 70 mg of purine per 100 g, and cooked soybeans contain less than 50 mg of purine. These contents are almost the same as those of broccoli, peas, spinach, green peppers, bananas and other fruits and vegetables with high purine content.
Combined with epidemiological investigation and clinical research, eating bean products such as tofu will not increase the risk of gout.

Tofu is made by grinding, boiling and solidifying soybeans. In the tofu family, there are three kinds of tofu, namely south tofu, north tofu and lactone tofu. Their raw materials are all soybeans, but the difference is that Beitofu uses brine as coagulant. The solidified tofu has rough texture, high hardness and high calcium content. South tofu uses gypsum as coagulant, and the solidified tofu has higher water content and lower calcium content than north tofu, but its texture is soft and tender.
Tofu originated in China and is the crystallization of the wisdom of China people. Not only delicious, but also nutritious and healthy. Rich in high-quality plant protein, dietary fiber, calcium, potassium, magnesium, zinc and other minerals, as well as soybean isoflavones and other health components. It is a veritable high-quality food with low calorie and saturated fatty acid content, which is very suitable for people with poor immunity, obese people, the elderly and patients with hypertension, cardiovascular and cerebrovascular diseases and diabetes. The 20 16 version of Dietary Guidelines for China Residents recommends eating 3050g bean products every day, which is about 200g tofu. Who can't eat tofu? Today, Dr. Sun introduces you one by one:
In a word, tofu is delicious and nutritious, which can be divided into north tofu, south tofu and lactone tofu. It has its own characteristics. Eating tofu in moderation every day is good for health, and it is a high-quality food recommended by China Dietary Guide. Menopausal women and kidney calculi patients can eat tofu, which will not cause cancer and will not accelerate the development of the disease. Patients with chronic kidney disease, gout or hyperuricemia should limit the consumption of tofu to avoid affecting the stability of the disease.
Who can't eat tofu? Qingming small holiday, friends gathering. At noon, everyone was going to eat stir-fry, because there is a very famous online celebrity shop in our gathering place, which belongs to an authentic fly restaurant. Although the environment is not good, this family is very famous, and everyone has been coveted for a long time, but many things are always planned to keep up with the changes;
A classmate changed the venue of the party to his company because he worked overtime temporarily, so he had to give up his dream fly restaurant and wait for the next opportunity to make an appointment;
Because of accommodating this classmate, at noon, the classmates who worked overtime invited us to eat mala Tang. I didn't know it was also an online celebrity shop until I went there. The small shop was crowded with people. In the process of eating mala Tang, such a thing happened, which surprised me. I learned from my classmates that Japanese tofu is actually not "tofu";
Here's the story. In Mala Tang's small shop, we each picked out our favorite food with plates. Students who worked overtime strongly recommended a tofu from this shop, but I politely refused because I had stones.
After asking about my illness, my classmates told me that it was okay to eat something. This kind of tofu is really edible. I was a little unhappy at the time. The classmate smiled and said, Don't be unhappy. Although this kind of tofu is called tofu, it is not what we understand. Its raw material is eggs, and its taste is close to steamed eggs. It is named for its shape similar to tofu, but it does not contain soybean ingredients. This Japanese bean curd is also called egg bean curd or Yu Zi bean curd.
After listening to my classmates, I really can't believe it. I couldn't resist the temptation and chose one. It's really delicious after eating. It's tender than the tofu we eat every day, and it smells like eggs.
Today, I saw this question from the subject: Who can't eat tofu? Reminds me of an interesting thing that happened a few days ago. I am a food blogger. Perhaps because of illness, tofu is naturally blocked. Through the introduction of my friend, I blushed a little and got back to the point. Then I'll tell you my opinion:
1, tofu is delicious, but I seldom eat it, or try not to eat it. The reason is relatively simple. I have a stone, which seems to be calcium oxalate stone. Because tofu is rich in calcium, I really dare not eat it. I dare not cross the line easily because of the pain after the stone attack.
2. Because tofu is rich in calcium, it is not easy to eat tofu when taking tetracycline drugs. It seems that tetracycline drugs will react when they encounter calcium and magnesium, so such people will not be able to eat tofu;
My parents don't like tofu very much either. This is what happens when they are old. When they were young, they would make tofu at home every once in a while. My mother likes to make fried tofu with edamame rice. In recent years, they have stopped eating tofu. I don't know where I saw the news or the result of my own practice. Every time I ask my parents why they don't like tofu. They always reply to me like this, saying that they are old and their physical function is declining, so they should try to eat less tofu;
My cousin's children like to drink soybean milk and eat all kinds of bean products. Later, when children grow up, they seldom make tofu for their children after puberty. The reason seems to be that soybean or bean products contain isoflavones. I heard it's plant hormones. Adolescent children still eat less, I don't know if this statement is true or not. Anyway, my cousin's family seldom makes all kinds of bean products for children.
5. I wonder if you have heard of gout? I have a classmate with gout. He said it seemed to be a disease caused by purine metabolism disorder. Bean products themselves contain a lot of purine, so if you have gout, you need to try not to eat bean products or tofu.
6. In addition, the purine in bean products will upset our stomachs. If you have stomach trouble, you may secrete a lot of stomach acid after eating bean products, which may easily cause flatulence, so when you have stomach trouble, it is best not to eat tofu.
7. What other situations can't you eat tofu? In my opinion, everyone's eating habits are different. For example, I like to eat preserved eggs mixed with tofu, especially in summer, but I am in poor health and can't eat tofu. Every time I eat all the preserved eggs in this cold dish, half a plate of tofu is left. My daughter-in-law is picky and worried about waste, so she forces herself to finish the remaining tofu on her plate every time. After many times, my wife also complained.
Finally, I want to say a few words. Who can't eat tofu? Through the above introduction, the questions about this topic are summarized as follows:
1. If you don't like tofu, try not to eat it. Although picky eaters are not a good habit, there are some things I really can't do. For example, I don't like Flammulina velutipes, but my wife likes it very much and watches her eat it every time.
Old people of my parents' age are definitely not as strong as they were when they were young, and they also have some basic diseases. So I still listen to my parents' ideas and try not to let them eat soy products.
3. Bean products contain some purines. Every time I make Mapo tofu for my daughter-in-law, I will blanch the tofu, hoping to minimize the purine in the tofu through this blanching process. Therefore, students with gout or stomach problems should eat less or not eat soy products;
4. Try not to eat when it is not delicious, especially tofu that is not very fresh.
First of all. According to the description of the subject, "some people say that tofu is a hair product", this question is refuted here. In modern medicine and nutrition, there is no such thing as hair care products. Most people think that hair is just some food rich in protein, but only those who are not allergic or intolerant to this kind of food can eat it.
Tofu is a kind of bean product and a kind of food with high nutritional value. Mainly rich in high-quality protein, unsaturated fatty acids, soybean oligosaccharides, dietary fiber, vitamin E, B vitamins, phytosterols, calcium, potassium, phosphorus, mucopolysaccharides and other minerals. It can be said that soybean or its products are rich in nutrition and have various health care effects, especially suitable for the elderly and patients with cardiovascular diseases. At the same time, it is a good source of calcium.
Tofu suits everyone. Anyone who can't eat tofu should be allergic to tofu, that is, to soybean protein. However, the following two kinds of people need to be restricted and cautious when eating tofu, such as:
First, gout patients
In addition to a balanced diet and a good lifestyle, gout patients should also try to avoid the intake of high purine food in the choice of food. For some foods with moderate purine content, remember to limit the consumption, while tofu is a food with high purine content, and the purine content is between 50-100 mg/100 g. Therefore, the consumption should be limited, generally not exceeding100 g.
Second, patients with renal insufficiency and chronic renal failure
Patients with renal failure need a low-protein and low-phosphorus diet, so the daily intake of protein and phosphorus should be given in stages. Although it is recommended to eat soybean protein and high-quality animal protein, the overall intake of protein should be limited. Therefore, we must treat it with caution.
First of all, the concept of hair is popular among the people and has no scientific basis. The possible reasons why people think a certain food is "hair" are as follows:
1. This food is high in protein, and excessive intake of non-quality protein is not good for the kidneys;
This kind of food is high in calories. Eating too much is not conducive to weight control, and may also lead to increased blood sugar;
3, the food tastes irritating, such as mutton, many people say that this is wool;
4. Food may carry parasites and cause discomfort after eating;
5, bad cooking methods, such as barbecue, frying, etc. Eating it will also cause some discomfort to some special people.
It can be seen that as long as they think that eating food may make their bodies feel uncomfortable, it will be called "hair" at that time. So tofu can't be called "Mao". In that case, who can't eat tofu?
Who can't eat tofu? 1, people who are allergic to protein can't eat tofu.
Allergies can be big or small. If they are allergic to protein, such people should not eat tofu. Eating a little may cause itchy skin, rash and other symptoms. Eating too much may be life-threatening.
2. Patients with kidney disease should eat less.
One or two northern tofu protein about 6g, one or two southern tofu protein 3g. Patients with kidney disease should not consume more than 48g of protein every day, so they can only eat 1-2 beancurd every day, and don't eat too much.
In addition, I know that many people think that people with gout or abnormal uric acid metabolism cannot eat tofu, which is a misunderstanding of tofu. This misunderstanding may come from the raw materials for making tofu. Soybean is a food with moderate purine content, and patients with abnormal uric acid metabolism are really not suitable for eating, but tofu has been processed layer by layer, and the purine content has been reduced a lot. Therefore, people with high uric acid can also eat tofu properly. After all, tofu contains protein, calcium and magnesium besides purine.
On the other hand, soybean milk is all bean products, and the purine content is higher than that of tofu, so gout patients should drink less or not.
Which bean products can't be eaten more? Speaking of tofu, I have to mention some of its "close relatives". Although tofu is good, it does not represent its "relatives". Some bean products are not suitable for eating.
1, fried bean products
Foods such as oily tofu and yuba can be fried, and the oil content is high, so patients with kidney disease and three highs should not eat too much.
2. Seasoned bean products
For example, soy products used for seasoning, such as fermented bean curd and fermented soybean, mostly contain excessive salt and oil and belong to heavy oil and heavy salt food. People with high blood pressure and hyperlipidemia had better not eat, and must control the intake of salt and oil.
3.chiba tofu
Thousand-page tofu can't be regarded as tofu in the true sense, because it is made of soy protein isolate, corn starch and egg white liquid, with few nutritional components and little nutritional value. In addition, many cooking methods of Chiba tofu are oily and salty, so it is best for patients with kidney disease to eat less.
4. Japanese tofu
Although there is the word tofu, it is not tofu at all, nor is it a bean product. Its main ingredients are water, eggs, salt and so on. And its unsaturated fatty acids are higher than ordinary tofu, and its salt content is not low. Eating hot pot and mala Tang is very common. Don't eat too much. Enough is enough.
Tofu is a nourishing and heat-clearing health food. Regular eating can tonify the middle energizer, clear away heat and moisten dryness, promote fluid production and quench thirst. Moreover, the soybean protein contained in tofu is the only high-quality protein comparable to animal protein, containing 8 kinds of essential amino acids in a balanced content. For special people such as hyperlipidemia and obesity, if you want to supplement protein, but you are afraid of eating too much fat, it is more appropriate to eat tofu.
Being friends with nutritionists can solve all kinds of problems in your diet. Welcome to Liao Kela Institute of Nutrition.
Who should not eat tofu?
The elderly and patients with renal insufficiency, urinary calculi, diarrhea, iron deficiency anemia and gout should not eat more tofu.
This content was reviewed by Guo Nan, Deputy Chief Physician, Second Division, Dongzhimen Hospital, Beijing University of Chinese Medicine.
Click here to see the details of the doctor's answer.
I haven't heard that people can't eat tofu, who is more unclear? How good tofu is! I love tofu and buy tofu once every three days. Tofu is really not cheap now. 3 yuan, 5 Jin is full of water. After I bought 7 yuan of tofu, I cooked it in the pot, leaving only 4 yuan of tofu, saying that the seller's tofu water was too big, and people said that everything was delicious. It's bean juice and water. It's really speechless [laughs] tofu. I can't afford it now, so I have to pick up some vegetable leaves and bark and cook some soup, not to mention it's delicious [laughs]. Try [like] [like] [like] Really, I can't bear you to cry [cover your face] [cover your face]
Apart from water, the main ingredient of tofu is protein. It is common sense that no one in the world can live without protein. However, the basic component of protein is that amino acids are arranged according to certain rules to form protein. There is a kind of people who can't eat tofu, that is, they can't eat it in protein, and there is a very small group, that is, people with allergies in protein. They can only eat special foods, which are amino acid foods.
