Tofu is good food!
Commonly known as "vegetable meat", it is made by grinding soybeans and adding coagulants (mainly calcium carbonate or magnesium chloride). On color, white as jade; On texture, delicate and soft; On the taste, the entrance is smooth, far better than the "fast-growing chicken" on the market at present!
Among them, "South Tofu", commonly known as tender tofu, takes calcium carbonate as coagulant, which is softer and more tender, and is suitable for making soup, Mapo Tofu and shallots mixed with tofu. "North Tofu", commonly known as old tofu, is a coagulant made of brine "magnesium chloride". It is hard in texture and yellowish in color, and can be used as home-cooked tofu, fried tofu, frozen tofu and other dishes.
Its main nutritional components, South Bean Curd contains 87.9% water, 6.2% protein, 100g contains calcium 1 16mg, potassium 154mg, iron 1.5mg, zinc 0.59mg and selenium 2.62mg
Tofu is a "national good food"! Nutrition experts recommend eating 25 grams of soybeans every day, which can be replaced by100g of north tofu or150g of south tofu.
Tofu, one of the representative foods in China catering industry, has a deep foundation, easily available raw materials, simple production, convenient purchase, affordable price, good taste, rich nutrition, easy digestion and environmental protection. It is an "excellent" food source for people to supplement high-quality protein and calcium, and it is a daily popular food for people of all ages in Xian Yi, with an irreplaceable "status"!
There are "side effects" of eating tofu on the Internet, such as indigestion, decreased renal function, arteriosclerosis, iodine deficiency and gout attack-it's completely nonsense!
First, whether tofu is easy to digest and whether there is any danger of bloating and diarrhea, you will know if you eat too much, and you don't need to explain.
Second, protein from plants is more friendly to the stomach, liver and kidney than protein from animals, at least in terms of digestion, absorption and metabolism. Moderate consumption will not cause any burden to liver and kidney.
Third, South tofu does not contain sulfur-containing amino acids (methionine and cystine), while North tofu does, but the proportion with other amino acids is not prominent. After normal metabolism, methionine and cystine will not accumulate in the blood, leading to "hyperhomocysteinemia" and atherosclerosis, which is caused by the lack of folic acid, vitamin B6 and B 12.
4. Soybean saponin has many health care values: regulating lipid metabolism, lowering cholesterol, resisting thrombus, resisting oxidation, inhibiting tumor and enhancing immunity, but it has no effect on promoting iodine excretion. Even if there is, how can cooking tofu with salt lead to iodine deficiency?
Fifthly, the purine content of bean products belongs to the "less" level (the purine content per 100 grams is between 25 and 75 mg). On the contrary, moderate intake of soy products is also good for gout patients! This is a guide to gout prevention and treatment experts.
In the process of soybean processing, crude fiber and phytic acid are removed, trypsin inhibitor and phytohemagglutinin are destroyed, and the absorption rate of some nutrients in tofu is improved to some extent!
Lactone tofu, the coagulant used is "gluconolactone", which tastes softer and smoother; Japanese tofu is made of eggs, water and additives, not bean products.
Tofu contains trace phytoestrogens (soybean isoflavones), which can be eaten 50- 150g a day, which helps to prevent female climacteric syndrome and senile osteoporosis and win more health points!
There are many rumors about diet, and middle-aged and elderly people should be careful when listening!
It is a good decision for middle-aged and elderly friends to eat tofu properly, but it is really inappropriate to eat too much tofu. Tofu is a soybean food, which inherits many characteristics of soybean, such as a large amount of protein, various minerals, especially calcium, and has a strong satiety. Bean products are also rich in high-quality plant protein. If middle-aged and elderly people eat too much, there are several disadvantages:
In a word, tofu is really good food, but you must be careful not to eat too much. Dietary guidelines also do not recommend excessive intake of soybeans. The daily intake of soybeans and nuts should be controlled within 30g, about 10g for nuts and 20g for soybeans. 20g soybean is about 200~300ml soybean milk converted into bean products, which is less than half of tofu and a piece of tofu skin, so it is not too much. Bean products are good food, but it is not recommended to stare at tofu. Bean products include soybean milk, bean curd skin and bean curd brain. We can take turns eating.
Other middle-aged and old friends don't like milk and eggs, but they have a soft spot for soybean milk. In fact, it is absolutely impossible for soybean milk to replace the nutritional value of egg milk. After cooking and dilution, the contents of calcium and high-quality protein in soybean milk decreased sharply, especially calcium. 100g milk can supplement 108mg calcium, while soybean milk can only supplement about 18mg calcium, and the difference is not a little. Long-term use of soybean milk instead of egg milk, without paying attention to the extra supplement of calcium and protein, may lead to the lack of protein and calcium, and middle-aged and elderly people are more prone to bone loss, so they still have to drink milk and eat eggs; I really can't drink milk, so I recommend yogurt to make up for the discomfort caused by lactose intolerance. You can also eat more fish and shrimp and proper meat to make up for it.
I eat everything ... I often rotate ... I don't like it or dislike it. It is neither beneficial nor useful. For example, I eat all kinds of oils, peanuts, rapeseed and olive oil. ......
Why can't middle-aged and elderly people eat too much tofu? I'm glad to answer this question. There are many benefits of tofu, so I won't talk about it. Everyone knows the importance of balance. In order to live a healthy life, people must live in harmony with nature. Whether it's nature or our own bodies. Everyone should pay attention to the balance of yin and yang. The balance between yin and harmony brings a healthy life. Yin and Yang are out of balance, and diseases abound. Both. This value is too high. Eating too much is not good. Old people often say that delicious food cannot be used for multiple purposes. Just be healthy. Reasonable and reasonable use. Staple food and non-staple food should be used reasonably together. A healthy diet is the most important thing. Too much chicken, duck and fish. It is easy to get obesity, hypertension, arteriosclerosis and diabetes. These are all wealth diseases. Then you have eaten too much tofu, and he is not as good as the best. People should live in peace with nature. We should make rational use of all kinds of delicious food in nature. That's a healthy life, which we China people often say. I also want to use this sentence to shine on myself. Then I wish you all the best and realize this ideal. It hurts too much. I hope our country will prosper. Then what is this sentence? Weather, geographical location and human harmony. I hope the country and netizens will use it to prosper. Family harmony. Good health. thank you
Why don't many elderly people eat more tofu? The answer is here!
The nutritional value of tofu is well known. Tofu itself is rich in high-quality protein and low in fat. Fatty acids are essential fatty acids for human body, mainly linoleic acid. For the elderly, tofu is a very good source of high-quality protein in the diet. Tofu itself is also rich in calcium, especially the calcium content of north tofu and south tofu is higher than that of milk. It is definitely a very high-quality food source for getting calcium in the diet. At the same time, tofu contains phytosterols and soybean phospholipids, which is beneficial to cardiovascular and cerebrovascular health. In addition to the nutritional advantages mentioned above, tofu also contains a variety of healthy ingredients needed by the body, and tofu itself has a soft taste, which is very suitable for the elderly with bad mouth. Tofu is so delicious, but you really can't eat more. Everything should be measured, and tofu should also be measured. It is suggested that the amount of tofu eaten by the elderly should be controlled within 80g every day. Arrange three meals a day reasonably.
It is a good choice for elderly friends to eat tofu properly every day. Bean products are rich in nutrition, soft and rotten in taste, conducive to digestion, low in fat and calories. Besides milk and eggs, it is a good source of calcium and protein. Dietary guidelines also recommend that the daily intake of soybeans is about 20~30g, and it is recommended to eat 50~80g tofu every day, which can almost get enough soybean nutrition. Tofu is a kind of bean product, which inherits the rich nutrients in soybean food, such as rich plant protein, rich calcium and various mineral components.
People with diseases related to renal metabolism need to strictly limit the intake of protein. People with hyperuricemia or gout need to limit the intake of tofu. Tofu is a high purine food. If gout has occurred, you should not eat tofu regardless of your age. People with hyperkalemia and hypercalcemia need to strictly control the intake of potassium or calcium.
I also want to advise the elderly not to eat moldy tofu. Although the nutritional value of moldy tofu has not lost much in the production process, it is much more salty than ordinary tofu. In order to facilitate long-term preservation, its salt content is relatively high, because a high-salt diet is a taboo for the elderly. As for moldy tofu, it is recommended not to exceed half a piece every day.
Five hazards of eating too much tofu for the elderly;
First of all, it will lead to kidney failure.
Under normal circumstances, after metabolism, most of the plant proteins that enter the human body will become nitrogen-containing waste and be excreted by the kidneys. However, the renal function of the elderly and some patients with kidney disease is declining. If they eat too much tofu, it will increase the burden on their kidneys and reduce their renal function, thus affecting their health.
Second, it will lead to indigestion.
Tofu is rich in protein. Once eaten in excess, these protein will accumulate in the human body, causing indigestion, which in turn will lead to abdominal distension, diarrhea and other uncomfortable symptoms.
Third, it will cause arteriosclerosis.
Tofu is rich in methionine, which can be converted into cysteine under the action of enzymes after entering the human body. Cysteine can damage endothelial cells of human arterial wall, make cholesterol and triglyceride deposit on arterial wall, and cause arteriosclerosis.
Fourth, it can cause gout.
Tofu contains more purines. Abnormal purine metabolism is the main cause of gout. Therefore, gout patients who eat too much tofu can easily cause gout attacks.
Five, can lead to iodine deficiency.
Tofu contains a substance called saponin, which can promote the excretion of iodine by human body. Therefore, if people eat tofu for a long time, it is easy to cause a large loss of iodine in their bodies and make them suffer from iodine deficiency. Of course, the above question is not to advocate that elderly friends should stay away from tofu. Proper diet will not have a great impact on the health of the elderly.
Can't middle-aged and elderly people eat too much tofu? This may be a misunderstanding of tofu by some people. Although the price of tofu is relatively cheap, it is two or three yuan a catty, but it has high nutritional value. People often say that Chinese cabbage and tofu are safe. For middle-aged and elderly people, eating tofu every day is very beneficial to their health.
With the growth of age, our teeth often have problems, and sometimes we refuse to eat meat because it is difficult to chew, which will lead to the lack of protein. The raw material of tofu comes from soybean, and the protein contained in it is high-quality protein. Eating tofu can supplement high-quality protein.
Osteoporosis is the most common bone problem in middle-aged and elderly people, and calcium deficiency is also an important factor. Tofu, especially north tofu, has a high content of calcium, which is undoubtedly a very good calcium supplement food for middle-aged and elderly people. Moreover, tofu also contains soybean isoflavones, which can promote the absorption of calcium and is more conducive to the health of female friends.
As for bean products, China Nutrition Society has introduced them in China Residents' Dietary Guide and China Residents' Balanced Dietary Pagoda. It is recommended to eat bean products every day, and tofu is one of them. Tofu is one of the cheap foods, so don't forget to eat some tofu every day.
Tofu tastes good, and old people and children can eat it with confidence. Tofu can be made into soup or fried. Friends who like to eat jiaozi can also make tofu jiaozi with tofu stuffing. Some friends also like to eat fried tofu, which is not healthy and will cause high fat intake and affect our health.
Under normal circumstances, protein, a plant that people eat in the body, undergoes metabolism, and finally most of it becomes nitrogen-containing waste, which is excreted by the kidneys. When people get old, the ability of the kidneys to excrete waste decreases. At this time, if you don't pay attention to your diet, eat a lot of tofu and take in too much plant protein, it will inevitably increase the nitrogen-containing waste produced in your body and increase the burden on your kidneys, which is not conducive to your health.
Old people eat tofu well, which can supplement calcium and has high nutritional value. Eating tofu is good for their health, especially for the elderly. You can't eat more tofu. I haven't heard of that. No matter what food, eating too much is definitely not good. You must have a certain quantity. Eating a single food can lead to malnutrition.
Indigestion
Tofu is rich in protein. Eating too much at a time not only hinders the absorption of iron, but also easily causes protein's indigestion, abdominal distension, diarrhea and other discomfort symptoms.
