Purine content varies greatly from soybean to tofu. We all know that tofu is processed from soybeans, and the purine content per 100g soybean is about 1 16.5mg, which belongs to medium purine food (when the purine content per 100g food is 25-150mg; /kloc-above 0/50mg is high purine food, and below 25mg is low purine food). After processing, the purine content per 100g tofu is about 55.5mg, so the purine content from soybean to tofu is almost reduced by half. However, soybean and tofu belong to medium purine food, not high purine food. Gout patients can eat it, but it should be limited. It is best to eat less when gout is acute.
Secondly, some foods derived from soybeans, such as soybean milk and bean sprouts, have a large gap in purine content, so gout patients should pay attention to it when eating. The purine content of soybean milk is about 27.7 mg100g, which is close to the edge of low purine food and can be drunk by gout patients. The purine content of bean sprouts is 500 mg per100 g, which belongs to high purine food. Long-term consumption will increase uric acid and even induce gout. Gout patients should eat as little as possible, or even prohibit eating.
What foods can gout patients eat with confidence? What foods can't be eaten? Low-purine foods are foods that gout patients can safely eat, mainly including rice, pasta, vermicelli, dairy products, eggs, sea cucumbers, mandarin fish, and most vegetables (except bean sprouts, mushrooms, laver, asparagus and bean sprouts). ), most fruits and dried fruits. Almost all of these foods belong to low purine foods, and a few belong to medium purine foods, so gout patients can safely eat them.
What precautions do gout patients have in their lives? All gout patients should drink more water, preferably more than 2000ml per day, to promote uric acid excretion; We advocate proper exercise for gout patients, but we should avoid strenuous exercise, because strenuous exercise consumes a lot of ATP, increases the source of uric acid and increases uric acid; Limit alcohol, whether beer or liquor, it is best not to drink, because alcohol will not only increase uric acid, but also inhibit uric acid excretion, which is not conducive to the control of the disease. Control blood fat, blood sugar and lose weight. If the blood lipid is too high, its metabolite ketone body will inhibit the excretion of uric acid. When blood sugar is too high and insulin resistance or hyperinsulinemia occurs, it will promote the absorption of uric acid by the human body.
To sum up, tofu belongs to medium purine food, not high purine food. Gout patients can eat and drink soy milk in moderation, but eat less or no bean sprouts. Rice, pasta, vermicelli, dairy products, eggs, sea cucumbers, mandarin fish, vegetables, fruits and dried fruits are safe foods for gout patients, while meat, aquatic products, bean sprouts, mushrooms, laver, asparagus and bean sprouts can be safely eaten. Secondly, patients with gout should drink more water, avoid strenuous exercise, limit drinking, control blood sugar and blood lipid, and avoid gout caused by elevated uric acid. Thanks for reading!
Gout patients have to avoid eating because of their illness, and doctors always tell them to eat high-purity food carefully. Tofu is also listed as one of the high purine foods, so can gout patients really not eat tofu?
1. What is gout?
Gout is a recurrent inflammatory disease caused by the increase of purine biosynthesis metabolism or poor excretion of uric acid, which leads to the increase of uric acid in blood and the deposition of urate crystals in synovium, synovium and cartilage of joints. According to its pathogenesis, gout patients should pay attention to avoid high purine food in their diet.
2. What is purine?
Purine is an organic compound, colorless crystal, which is oxidized and metabolized into uric acid in human body. High-purine food is specifically defined as food containing purine 100 ~ 1000 mg per1000 g, such as animal liver, kidney, pancreas, brain, minced meat, gravy, broth, mackerel, anchovies, sardines, fish eggs, shrimps, etc. You may find these foods with high purine content delicious, because "freshness" is really related to purine! In short, having gout is like having no food.
3. Can gout eat tofu?
Gout patients talk about "high purine food" and are afraid to eat anything. In fact, this is a misunderstanding, especially tofu, which is cheap and nutritious, and can still be eaten properly. Tofu is rich in nutrition and contains trace elements necessary for human body, such as iron, calcium, phosphorus and magnesium. It also contains sugar, vegetable oil and rich high-quality protein, and is known as "vegetable meat". The digestion and absorption rate of tofu is above 95%. Two small pieces of tofu can meet a person's daily calcium requirement. Although soybean is a high purine food, in the process of making tofu, the purine content has been greatly reduced by soaking and squeezing water, so even patients with hyperuricemia (early gout) can eat bean products such as tofu, dried bean curd and soybean milk in moderation.
Zhang Fan, Ph.D. in Nutrition
If we simply look at the purine content of tofu, its purine content is more than 60 mg per 100 g, which belongs to the food with medium purine content. It is generally recommended that gout patients eat less, especially when they have an attack. But is this understanding really correct?
Because I usually like to eat all kinds of bean products, I also checked some documents and reports after seeing this problem. One of them caught my attention and belongs to foreign reports. But after all, Singaporeans are mostly Chinese, just like us.
The introduction of the research report is to study whether eating tofu will increase the risk of gout and whether it will lead to gout recurrence. The research conducted by experts involved more than 50,000 Singaporeans from China. Respondents were 45-74 years old when they were recruited in 1993- 1998. The researchers asked about their eating habits and followed up the medical problems from 1999 to 2004 and from 2006 to 20 10. Of the 5114 people they followed up, only 2 197 people suffered from gout, and the incidence rate was 4.2%. Moreover, it is also found in the study that people who eat the most soy products have a lower risk of gout than those who eat the least!
Isn't it amazing?
Dr. Xie read this document and some research reports from Japan and Taiwan Province Province, and learned that scientists have reached similar conclusions. These studies show that eating soy products such as soybeans and tofu will not increase the uric acid content in the blood!
Now research shows that eating vegetables rich in purine, such as beans, spinach, mushrooms and cauliflower. Will not increase the possibility of gout.
Back to reality, research is research. What should I do in clinic? The above research has not found out why eating soy products will not lead to the increase of uric acid, but the conclusions drawn from some big data and perennial follow-up are universal. However, there are some patients in clinic. As long as you eat a large amount of tofu, gout attacks will occur, which is believed to be caused by everyone's different physique.
So should tofu be eaten after all? Personally, I think it is completely edible! After all, clinical studies in so many countries have confirmed that the intake of plant high purine components will not increase the risk of gout attacks.
Just pay attention to the quantity and frequency of intake. After all, our living material resources are much richer now. Even if we like tofu again, there is no need to consume a lot of tofu every day. There are many foods that can supplement protein, such as eggs. Why should we compete with tofu? ?
Moreover, cooking methods are also very important. For example, if you want to eat tofu, you must make seafood tofu soup, or eat tofu with seafood sauce and mushroom sauce, which is likely to lead to gout. After all, the purine content of seafood and many sauces is surprisingly high.
Although up to now many doctors will tell patients not to eat beans, cauliflower and mushrooms, these are high purine components in plants. However, medical research has been progressing and many concepts are constantly being updated. There are many factors that lead to gout attack. Many people's gout attacks are caused by endogenous reasons, and controlling diet is only part of controlling gout attacks. Personally, as long as we adhere to the correct living conditions, drink plenty of water, do aerobic exercise properly, and ingest some ingredients with moderate and small purine content, there is no problem at all.
The above is the answer to your question. Personally, I think gout patients can eat tofu. As long as we control the quantity and frequency of intake and pay attention to cooking methods, we can avoid gout attacks.
I am Xie Xinhui who insists on explaining the knowledge of complex diseases in easy-to-understand language. Codewords are not easy. If you agree with me, please help me pay attention to or like it. If you are a gout patient or have friends or relatives with gout, please help me forward this article to others who need it. Thank you! Gout patients can eat a small amount of tofu, including other bean products, such as soybean milk and dried tofu. Tofu is a product made from soybeans. Many gout patients will feel afraid to eat these bean products because of the high content of purine in soybeans, which is the main synthetic substance of uric acid. Excessive uric acid will cause uric acid crystals to accumulate in joints, causing joint swelling and pain and inducing gout. Therefore, it is necessary to control the content of purine in food. Gout patients should choose foods with low purine content. Does tofu come from soybeans with high purine content? Can you really eat it?
Tofu is indeed a food that gout/hyperuricemia patients can choose. Although soybean has high purine content, tofu will be soaked and diluted in the production process, and the purine content of tofu has been greatly reduced. In addition, when we are cooking, cooking and heating will further reduce purine, so the purine contained in tofu is actually not high. In contrast, tofu is rich in nutrients and minerals, especially calcium and protein, which is very suitable. Many gout patients love to drink soybean milk but dare not. In fact, soybean milk is also an absorbed bean product, and the purine content is not too high, so it can be properly drunk. For example, it is no problem to eat 100g tofu and 200ml soybean milk every meal.
The main cause of gout induced by gout patients is high uric acid in the body. Uric acid is the main factor inducing gout, and purine is the main factor increasing uric acid content. However, purine is not only ingested from food, but also an endogenous purine source secreted by itself. Endogenous purine is the main source of total purine, accounting for about 70% of total purine, but we can't actively control it ourselves, and only 30% of exogenous purine is ingested from food. In fact, even eating a little high purine food will not. In order to cooperate with endogenous purine control, it is best to mix drugs with food, and the effect will be better.
In fact, plant food is very beneficial to the metabolism of uric acid. Lecithin, soybean isoflavone and other ingredients in bean products are helpful to regulate uric acid and gout, but moderate consumption can prevent frequent gout attacks, so I don't agree that gout patients can't eat tofu, but moderate consumption of tofu is very beneficial to their condition.
Patients with gout should control the concentration of blood uric acid. Although endogenous uric acid produced by human body accounts for two thirds and exogenous uric acid accounts for one third, the high blood uric acid is not entirely caused by eating, and food accounts for one third.
Gout is the result of persistent hyperuricemia. When sodium urate in body fluids is continuously saturated, under certain conditions, such as fatigue, alcoholism, improper diet, excessive intake of purine in viscera of big fish and big meat, aquatic products and seafood, blood uric acid will increase, and local cold, excitement, tension, high tension, fatigue and excessive exercise will occur. Sodium urate dissolved in body fluids will be supersaturated to form sodium urate crystals, which will be deposited in human joints, kidneys and other tissues, and then go through a series of processes. So eating a food with high purine is equivalent to injecting high concentration of uric acid, so you should also pay attention to the intake of purine in your diet.
However, gout diet has more than three lows: "low calorie, low fat, low purine, drink more water and stick to it", and the restriction on purine is the third.
Reasonable calories and balanced nutrition are the "kings". The first principle of gout diet and diabetes, hypertension and hyperlipidemia diet is to limit total calories. It is 20% lower than the recommended calorie intake of normal people and about 300 to 600 calories lower than the recommended amount. It is very important to reduce your weight to a normal level through daily exercise. Because if you only limit the intake of purine and ignore the total calories, eating too many steamed bread, rice and fruits (all low in purine) will also turn carbohydrates into fat and get fatter and fatter, which is not good for gout control. If the total calories and the balanced intake of nutrients in the three major production capacities are within the standard range, the calorie intake will be reduced by 300 ~ 500 calories. After all, the purine you eat is exogenous, accounting for only 20% to 30%. Under the premise of controlling the total calories, you won't eat a lot, and it's okay to eat delicious lean chicken and tofu occasionally.
The traditional low-purine diet lists high-purine foods such as animal viscera, seafood, meat, wine and bean products as taboos for gout patients. In recent years, many clinical and epidemiological studies have further evaluated the influence of diet on gout, and identified animal viscera, red meat, seafood and wine with high purine content. It is a risk factor for gout and should be avoided as much as possible. However, the right amount of poultry, vegetables rich in purine and soy products (don't drink a lot of soy milk) have little effect on gout.
Restricting the intake of purine is mainly to limit the intake of purine in animals, while vegetables rich in purine will not significantly increase the blood uric acid level. The intake of vegetables by healthy people is related to the decrease of blood uric acid level and the risk of kidney calculi's disease. 20 12 ACR gout guidelines encourage gout patients to eat fresh vegetables.
Beans and bean products (such as tofu, tofu, etc.). ) is a traditional food in Asia, which used to be considered as high purine food. It is recommended that gout patients avoid eating. At present, it is found that the intake of beans and bean products is a protective factor of gout, and its possible mechanism is related to the uric acid excretion of beans. In addition, beans and bean products are rich in protein, which can make up for the reduction of protein intake caused by the restriction of red meat intake and reduce the risk of coronary heart disease. Therefore, gout patients can increase the intake of beans and soy products. Bean products such as bean curd, dried bean curd and bean skin. During the processing, most of the purines in soybean milk are removed, and purines are water soluble. In the process of making bean products, tofu, dried tofu and bean skin remove a lot of water and purine. It is safe to eat 100g tofu every day. But don't drink a lot of soy milk. Drinking a cup of soybean milk every day is ok on the premise that the total calories are not over the standard.
The saying that gout patients can't eat soy products has been circulating among the people for a long time. In the TV program of seeking medical advice, it is often seen that some experts categorically cut off a patient's idea of trying soy products. In the quiz of a variety show, bean products were also included in the diet blacklist of gout patients. Through the media, it seems that this statement has become a household name, right
In fact, in the "food purine content table", soy products are only at a warning level that needs to be limited. In fact, relevant scholars have studied and determined the purine content of food and found that the purine content of most beans is not too high. Another common phenomenon can also help to "correct the name" of bean products: in order to ensure the supply of protein, vegetarian monks prefer beans. In vegetarian culture, bean products are almost inseparable, but in fact, the proportion of monks suffering from gout is very small. It can be seen that it is unreasonable to regard beans and bean products as "scourges".
However, gout patients can safely choose tofu when choosing soy products. You can eat a palm-sized bean curd every day,100g, provided that the total calories do not exceed the standard. But you can't drink too much soybean milk. It is no good drinking five or six cups of soybean milk as water a day. The reason is that purine is a water-soluble substance. When making tofu, the purine in the bean has been "floated" away, and the purine content in the finished tofu has become less. In the process of grinding soybean milk, purine resides in soybean milk. It is also a bean product, and the purine content of soybean milk can be many times better than that of tofu.
This is a gout meal for your reference. This set of 450 cards has 50 grams of bean skin.
Gout patients can eat tofu in moderation.
Through the analysis of the development of gout treatment, we can draw the conclusion that tofu will not cause gout attack. One of the traditional methods to treat gout patients is to reduce the purine content in the food they eat. However, with the continuous development of modern medicine, the scientificity and effectiveness of this treatment method have been questioned more and more. The results of modern nutrition research prove that strict control of purine content in the diet of gout patients has not achieved good therapeutic effect, while other nutritional treatment methods such as weight control, alcohol intake restriction and blood triglyceride content control have achieved good results in the treatment of gout patients. A diet containing proper amount of purine may be more helpful to gout patients than a diet with strict control of purine content, especially those patients who can't control the uric acid content in plasma by taking uric acid-lowering drugs, and should take a certain amount of purine through diet. This is because although foods with high protein content contain a lot of purines, which will increase the production of purines in the body, such diets usually increase the excretion of uric acid, and may even reduce the level of uric acid in plasma.
It can be seen that in foreign reports on the relationship between tofu and gout, it is not mentioned that moderate consumption of tofu will increase the content of urate in plasma of gout patients. On the contrary, clinical experiments have proved that tofu will not cause a significant increase in the content of urate in plasma of gout patients, and it can be used as a healthy diet for gout patients. There are also related literature reports in China, but the conclusions in this paper have not been proved by experiments. Just take it for granted that the high content of purine in tofu will lead to the increase of urate content in plasma of gout patients. This conclusion is groundless and wrong.
Benefits of Gout Patients Eating Tofu
According to the analysis of modern nutrition, tofu will not cause gout attack, which fully meets the requirements of healthy diet for gout patients and has the following advantages:
1, the protein content of tofu is high, which is beneficial to promote the excretion of urate in gout patients.
2. Tofu has low fat content and low energy, which is beneficial to control the weight of gout patients and the content of triglyceride in plasma, thus reducing the risk of the increase of urate content in patients' plasma.
3. Tofu contains a certain amount of purine, which meets the requirements of modern nutrition for gout patients, that is, gout patients are allowed to contain a proper amount of purine in their diet.
4. Tofu is rich in isoflavones, unsaturated fatty acids, vitamins, oligosaccharides and other nutrients, and has many health functions, such as preventing and inhibiting liver diseases; Prevent and inhibit the occurrence of diabetes; Prevent and inhibit arteriosclerosis; Prevent and suppress colds and influenza. It is beneficial for gout patients to improve their physical fitness and enhance their self-recovery ability.
The raw material of tofu is soybean. Soybean has a high purine content, which is similar to meat. It belongs to high purine food. For people with gout, try to eat less soybeans (especially dried soybeans). Because tofu is made of soybeans, many gout patients are afraid to eat tofu, thinking that tofu is also a high-purity food, which will increase the risk of acute gout attack, but this understanding is actually incorrect. Tofu is a low-purine food, and gout patients can eat it completely.
Tofu is a very common food in our life, which is rich in nutritional value and deeply loved by the public. Tofu is made by dissolving soybeans in water many times, and the purine content has been diluted dozens of times. At the same time, because purine is easily soluble in water, the purine in tofu is further diluted, and it has already become a low purine food, which is suitable for gout patients. Similarly, the same is true of soybean milk, the purine content is significantly lower than that of soybean, and gout patients can also drink it properly.
Of course, due to the differences of our personal constitutions, the diet of gout patients needs to be individualized, choose the food that suits them, pay attention to improving their lifestyle, and take medicine regularly to stabilize their condition. In daily life, we should strictly limit the intake of high-purity food, avoid eating animal viscera, shelled seafood and broth, and eat less animal meat, fish, dried mushrooms and dried beans; Eat more fresh vegetables, drink more water, white water is appropriate, and avoid fructose-rich drinks such as juice and cola; Quit smoking and limit alcohol, you can't drink alcohol in acute stage, and you can drink some red wine in remission stage; Exercise properly, keep warm and control your weight; We should have a regular routine and keep a good attitude.
While actively improving the lifestyle, we should also take uric acid-lowering drugs regularly under the guidance of doctors to dissolve and excrete urate crystals to the maximum extent. It is suggested that the serum uric acid level should be controlled within 360 umol/L. If tophus is formed or chronic gouty arthritis often occurs, it should be controlled within 300umol/L, but it should not be lower than180 umol/L. It should be noted that it is not recommended to start reducing uric acid in the acute stage of gout. We should actively diminish inflammation and relieve pain first, and then start the treatment of uric acid-lowering drugs after the condition is relieved.
Hello, everyone, I am this beautiful piece of tofu. I was born white, absolutely no beauty filter, no peeling, no hyaluronic acid.
There were not so many gout patients in the past, so there was little research on me, and even doctors didn't know me. They even plausibly said that because I am made of soybeans, the purine content of bean products is high, and gout patients will have an attack after eating them. Even I believe in myself.
Then, with more and more gout patients, scientists have studied me more and more. At first, they found that after many gout patients ate me, the incidence did not increase. This is very strange. I'm full of hope myself. Won't I cause gout attacks?
So I seriously thought about my birth. As the saying goes, "grinding bean curd, grinding bean curd", I ground it under a stone mill, adding water while grinding. I'll do it twice if it's not enough, or 10 if it's not enough. I can't remember how many times, many times anyway. The soybean milk that comes out like this is what I used to look like. In this process, a large amount of water is added to filter, and most of the purines are washed away. Finally, as we all know, I was born when I cooked these soymilk and squeezed it out. Come to think of it, I really have very little purine content.
Later, scientists began to study again, saying that I not only have less purine content, but also have diuresis, which is good for gout! I am happy to call my husband immediately, but unfortunately, I just learned that he has been made into stinky tofu.
Until recently, a foreign expert published an article, which was very convincing. It tells human that there is a difference between plant purine and animal purine, and plant purine will not cause gout because it is difficult to absorb and transform.
Ha ha ha ha, finally proved that I am innocent and tender tofu, and I picked up my mobile phone happily again. I want to call the elder brother of bean curd, the elder sister of soybean milk, the elder brother of bean curd flower and the elder sister of bean curd residue, and I want to tell them that they are all innocent and will not cause gout attacks!
Oh, my husband is back. It stinks. As the saying goes, "stinky tofu smells bad and tastes good." Stop it! I'm going to eat him today!
Some people say that gout can't eat tofu. Is it true?/You don't say. Why?
Tofu is a very common food in our life, and many people like it, but gout patients don't know whether they can eat tofu because they need to strictly control their diet. Today I will share some knowledge about gout.
1. Is the soybean purine content high? In fact, the purine content of soybean is quite high. According to the analysis,100g of soybean contains about 200mg of purine. It can be seen that the purine content of soybean is catching up with that of animal viscera, and patients with gout should not eat soybean.
2. How is tofu made? It mainly includes cleaning soybeans, soaking soybeans, grinding, filtering bean dregs, boiling soybean milk, ordering brine and finished products.
3. Soybean purine is so high, can gout patients still eat tofu?
Through the above-mentioned tofu making process, we can see that many components of soybean are lost, and of course the purine content will also decrease; In addition, a large amount of water is added in the process of turning soybean into tofu, which is diluted by about 20 times, so the purine content of tofu is equivalent to per1100g purine 1mg, which is already a low purine food, so gout patients can eat tofu;
4. What should gout patients pay attention to in their daily life? Finally, it is concluded that tofu actually belongs to low purine food, and gout patients can eat it; But don't eat tofu with many additives, which will affect uric acid metabolism. The above is my answer to this question, purely by hand. It is not easy. If you think your writing is ok, you can praise it ... gout has always been considered as an eating disease. This kind of pain is caused by excessive accumulation of uric acid in the body, which crystallizes at the joints, and uric acid comes from purine decomposition. Therefore, avoiding high purine foods has become an important principle to prevent gout attacks.
Purine mainly exists in foods rich in protein, and soybeans are also rich in protein, so soybeans and their products, including tofu, soybean milk and bean skin, are also included in the blacklist of gout diet. The purine content of soybean and pea is really high, which is 166.5mg and 229. 1mg per 100g, respectively, higher than that of meat. From this perspective, it seems that gout patients really need to eat less beans. But is this the case? No.
Take soybeans as an example. After soybean is made into soybean milk, the water content is greatly increased, and the purine contained in it is also greatly diluted-the purine contained in soybean milk purchased daily is only about 20mg, and 1 cup of concentrated soybean milk is about 38mg. People with gout can drink a cup, but they can't drink it as water.
After soybean is made into tofu, the purine content per 100g is also reduced to 55mg, which is a food with low purine content and can be eaten completely, but attention should be paid to appropriately reducing the intake of other protein foods, especially meat (key! ) 。 For patients with gout, the protein per kilogram of body weight 1g per day is appropriate, and it can be limited below 0.8g when the condition is serious, and plant protein (such as soybean protein) is the main one.
A study of 20 12 found that the higher the protein intake of animals, the higher the risk of high uric acid; The higher the plant protein intake, the lower the risk of high uric acid. The total intake of soy products has nothing to do with the risk of high uric acid, but the intake of soy products is negatively related to the risk of high uric acid, that is, the more soy products are eaten, the lower the risk of high uric acid-among the 3978 middle-aged and elderly men who participated in the study, the risk of high uric acid in the top 20% is lower than that in the bottom 20% 1/5.
Conclusion: Gout patients can eat bean products such as tofu. But the most important dietary preventive measure is to reduce the intake of animal protein.
