Many middle-aged and old friends like to use tea instead of white water. In their minds, tea is more conducive to health (especially in the prevention of chronic diseases), poetic and can cultivate sentiment, while white water is insipid. But if you use tea instead of water every day, will it have any adverse effects on your health?

If the tea leaves are soaked very lightly and new tea leaves are not added frequently, it doesn't really matter much. Some friends have unique "old tea stains" on tea sets that have been used for many years. These tea stains don't need to be soaked in new tea, but they will smell like tea when poured out with water, so the soaking method of new tea can completely replace boiling water without adding extra water.

However, many friends make a cup of new tea every once in a while and throw away the tasteless old tea, so that tea can't replace white water. Even for light tea, it is actually recommended that you drink no more than 500 ~ 700 ml per day (the recommended daily consumption is 1500 ~ 2000 ml), because although tea is a healthy drink, the caffeine content in it can not be ignored, and the caffeine content in tea can even exceed that of coffee. For example, 100g black tea contains 30 ~ 40 mg of caffeine. Long-term excessive intake of caffeine will pose a certain threat to the nervous system, and may also cause excitement, insomnia and dependence; Excessive intake of caffeine can also lead to calcium deficiency and osteoporosis.

Tea contains some natural plant ingredients, especially green tea. Because it has not been fermented, the content of phytic acid, tannic acid, dietary fiber and other components is high. If these ingredients are ingested too much, it may also cause certain irritation to the gastrointestinal mucosa, causing symptoms of indigestion and gastrointestinal discomfort, especially for some people with damaged gastrointestinal mucosa. It is not recommended to drink strong tea, which will contain more caffeine and irritating ingredients. In a word, drinking tea properly every day is a good thing, and tea is our good partner. For example, insisting on drinking green tea will help reduce the mortality rate of myocardial infarction and cerebral infarction and prevent the three highs, especially the outbreak of diabetes; Drinking tea also helps to refresh the mind, soothe the liver and relieve depression, and improve irritability and anxiety. However, tea is not suitable to replace boiled water, especially its caffeine content can not be ignored, so you can drink tea properly every day.

Tea and boiled water are healthy drinking water. To a certain extent, drinking tea is not only beneficial to health, but also can replenish the body's water. But tea can't completely replace boiled water. This is because:

First, the human water requirement is 2500ml. Together with the water intake in food, the amount of pure drinking water is 1500ml- 1700ml to meet human needs and maintain normal renal function excretion. If you want to drink tea, it is impossible to drink so much tea, because the tea you drink every day is limited, generally not more than15g. To make so much water, you must drink tea before drinking (very weak).

Second, people are not suitable for drinking tea when they are sick or have a cold. Only boiled water can replenish body water, expel toxins and reduce inflammation. Although tea also has the function of detoxification and diuresis, there are other ingredients in tea, which are not conducive to patients taking drugs and may also weaken the role of drugs.

Therefore, in daily life, drinking tea in moderation is helpful to prevent cardiovascular and cerebrovascular diseases. But it can't completely replace it.

Although there is no detailed research report on the harm to health if you only drink tea instead of white water, you should pay attention to drinking tea. Drinking tea is not suitable for everyone, and tea cannot completely replace boiled water.

Tea has many benefits, but if you drink too much, it may harm your health. Let's talk about it 1, the benefits of tea

The ingredients of tea have to say the benefits of drinking tea: for example, accelerating the metabolism of fat and having the effect of losing weight; Promote gastric acid secretion, which is beneficial to digestion; Conducive to preventing hyperlipidemia; It is also beneficial to soften blood vessels and prevent arteriosclerosis. It also has antioxidant effect and is beneficial to anti-aging; Tea also has many vitamins.

2. Disadvantages of tea

It's okay to drink normally. When you drink too much, the problem comes:

(1) affects the stomach.

There is tannic acid in tea, which will react with protein in food. The formation of astringent protein tannins will reduce gastrointestinal peristalsis, which is not conducive to the absorption of protein.

(2) Iron absorption

Polyphenols in tea will react with iron in food, making it difficult for iron to be absorbed. It may lead to iron deficiency in the body. Because iron is the main component of hemoglobin, ischemic anemia may occur. Anemia is very harmful, which will affect the production and development and the function of body organs. You will also feel dizzy, and your normal work and study efficiency will plummet.

(3) Refreshing the brain

Yes, there is caffeine in tea. It has the same effect as coffee. If you drink it in moderation, it is ok. You drink too much tea. It is possible that insomnia, coupled with long-term nervous excitement and poor rest, will increase the risk of cardiovascular and cerebrovascular diseases and affect the absorption of calcium, leading to backache, leg pain and leg cramps.

Generally speaking, drinking tea in moderation is good for health and refreshing. Drinking too much will be unhealthy.

Water is a very important necessity for human body. People can live for about a month without food and water, but it is estimated that they can only live for a week without water. Ordinary adults need about 1500~2000ml of water every day. Lack of water may lead to physical discomfort, constipation, heatstroke, decreased metabolic capacity, unconsciousness and even severe shock. Then, can we use other drinks instead of water? Tea, for example, is very popular in China.

It is not recommended to use other water instead of boiled water, especially drinks with high ion concentration, such as cola, milk tea, sweet drinks, strong tea and thick soup. Although these drinks contain some water molecules (in fact, what we need is the ingredient of "water"), because of their high ion content and heavy taste, they may increase the osmotic pressure outside cells and blood vessels, oppress them and dehydrate them, which will actually make them more thirsty and affect their metabolism. Light tea, light lemon and light honey can replace boiled water because they contain more water and less other ingredients, but drinks such as light tea and light honey are not suitable for daily hydration. Light honey also contains honey, which contains high glucose, sucrose, fructose and other ingredients. Although it will not pose a threat to blood sugar at one time, if you always drink too much, it will pose a greater threat to blood sugar.

Replacing boiled water with tea also has disadvantages. Tea contains some natural ingredients such as phytic acid, tannic acid and dietary fiber. If these ingredients are ingested too much, it may irritate the gastrointestinal mucosa, especially for some friends with poor gastrointestinal function. Drinking too much tea may also cause gastrointestinal discomfort, indigestion, abdominal pain and stomachache. In addition, tea contains a lot of caffeine, and we all think that drinking coffee has a higher intake of caffeine. In fact, the caffeine content in tea is similar. The caffeine content of black tea and green tea can be the same as that of ordinary coffee. If you take too much, it may cause certain stimulation to the nerves, and it may also cause dependence. Excessive caffeine intake will cause calcium deficiency and increase the probability of osteoporosis, not to mention strong tea; If there is light tea, it is recommended to drink about 500ml every day, and it is not advisable to drink more.

Personally, I like to use tea instead of boiled water, but I usually only change tea once in the middle. Many friends will change into new tea after drinking a cup of tea. If so, the amount of tea you drink that day is equivalent to drinking several times of strong tea, which is actually unhealthy. Tea is actually a good drink. Green tea is rich in tea polyphenols, which is an antioxidant component, which helps to resist free radicals and has the potential to improve and prevent the three highs. Black tea has a lasting aroma. After fermentation, it produces more easily absorbed amino acids, vitamin B family, which can also soothe the liver and relieve depression and improve the brain. Many flower and fruit teas and cereal teas are also good choices. They are generally helpful for diuresis and thirst quenching, clearing away heat and promoting fluid production, but it is best not to completely replace tea.

Health first knows: drinking tea without drinking water can also play a role in replenishing water. In addition, some ingredients such as tea polyphenols contained in tea are good for health, but drinking tea or strong tea before going to bed is not good for health.

Tea, together with cocoa and coffee, is called the three largest non-alcoholic beverages in the world. It is a kind of beverage brewed with leaves or buds of tea trees, which originated in China and later extended to all herbal teas brewed with flowers, leaves, seeds and roots of plants.

Replacing water with tea can also play a role in replenishing water. In addition, some ingredients contained in tea, such as tea polyphenols, are beneficial to health, which can refresh the mind, delay aging, help lose weight, nourish the stomach and protect the liver. But drinking tea is not necessarily good for health, and drinking tea or strong tea before going to bed is not good for health. Therefore, drinking tea should be based on your actual needs and not blindly.

No beverage, including tea, can replace water, which is the source of life. Ordinary people should ensure 8 glasses of water every day (China Dietary Guidelines recommend daily drinking 1500- 1700ml), so drink water quickly!

Use tea instead of water every day. What harm does drinking too much tea do to your health?

Compared with boiled water, tea contains a lot of tannic acid, theophylline and other substances. A large intake of these substances will increase the stimulation to the gastrointestinal digestive system, have a greater impact on people who are sensitive to the gastrointestinal tract, and even induce discomfort such as heartburn.

If you drink too much tea, you will consume more caffeine. An increase in caffeine intake will undoubtedly make your heart beat faster, increase the burden on your heart and lead to an increase in blood pressure; The longer the time, the greater the amount of tea and the higher the risk.

I'm not scaring you. Any substance may be a safety hazard. If you like a certain food very much, it is easy to lead to "excessive consumption". Suppose you buy a certain kind of tea with food safety problems, and eating too much will increase the risk of food poisoning.

Therefore, we have always suggested that everyone should have "diverse foods and balanced nutrition". Only with more samples and fewer samples can food safety risks be avoided.

Simply drinking a lot of water itself may increase the risk of "water poisoning" and lead to problems such as edema in the body. The perfect combination of tea and water is more likely to increase the amount of drinking water and even lead to the problem of "water poisoning".

Besides these, there are some misunderstandings in Jianghu rumors, such as "drinking tea will inhibit the absorption of iron and induce anemia" and "drinking tea will react with protein and aggravate constipation". Although tea contains a certain amount of tannic acid, please don't forget that gastric acid (acidity) contained in the stomach is much stronger than tannic acid and other substances, and its existence will not cause much waves.

Drinking tea is a good thing and a positive hobby, but the premise is "enough is enough, healthy tea".

Choose the right tea, not just comment on the price:

Tea is expensive and cheap, and many people blindly pursue those "extremely expensive teas", which is really unnecessary. Choose "tea that suits you" when drinking tea.

The two principles of choosing tea are "tea you like" and "tea you can afford".

Tea, please taste "light tea":

Many people like to drink strong tea, thinking that strong tea tastes more refreshing, but this is a "misunderstanding" in itself.

Strong tea contains more caffeine, tannic acid and other substances. Drinking too much will increase the irritation to the gastrointestinal tract and aggravate the discomfort of the gastrointestinal tract. Relatively speaking, it is recommended that you drink light tea with fragrance, and the daily consumption of tea should not exceed half of the total drinking water.

Tea time should be arranged reasonably;

Many people like drinking tea on an empty stomach. If your stomach can accept it, you can "drink" it without deliberately limiting it. But for most people, it is recommended that you drink tea half an hour after meals to reduce irritation and play an appropriate role in helping digestion.

In addition, drinking tea is simple, pay attention to a healthier temperature, and avoid irritating and hurting your esophageal mucosa because of drinking hot tea. It is recommended to drink tea at around 40 degrees Celsius, and the highest temperature is not recommended to exceed 65 degrees Celsius.

Don't drink too much tea when you are healthy, and it is "healthy" to drink good tea; It is safest to seek advantages and avoid disadvantages, and your health is your decision.

First, drinking tea can control blood lipids to a certain extent.

Studies have shown that drinking tea can reduce the level of low-density lipoprotein cholesterol, which is called bad cholesterol. Too much low-density lipoprotein cholesterol in the blood will increase the risk of atherosclerosis, so drinking tea is actually beneficial in this respect.

Moreover, studies have shown that drinking tea can help delay the decline of high-density lipoprotein cholesterol, that is, good cholesterol. So in general, drinking a proper amount of tea is good for our health, mainly in improving blood lipids. Green tea is more recommended than black tea.

Second, we need to be alert to caffeine and oxalic acid in tea.

Some people like to drink strong tea, thinking that it will taste better, but the concentration of caffeine and oxalic acid in strong tea will be higher. Excessive caffeine intake will lead to an increase in blood pressure and blood sugar, which is also very unfavorable for patients with hyperlipidemia, and even some symptoms such as accelerated heart rate and palpitation, as well as sleep disorders.

The daily caffeine intake should be controlled within 400 mg, but generally speaking, there will be 40~70 mg of coffee in 150 ml of tea, and if it is brewed repeatedly, the caffeine may be higher.

In addition, too much oxalic acid in tea will stimulate your gastric mucosa. Some people may drink tea on an empty stomach and have some symptoms of stomach discomfort, which is also due to the stimulation of oxalic acid.

Third, how to drink tea correctly?

Some people like tea, but they can't drink boiled water. In this case, it is suggested to drink some light tea to make the tea taste a little, which will help them drink more water. However, if someone likes strong tea very much, this habit will be changed.

However, in fact, weak tea and strong tea are also related to the habit of making tea and the variety of tea you choose, so you can't give an exact value, but it is not recommended to make a cup of tea all day, or to drink tea instead of boiling water all day.

Besides the concentration of tea, be careful not to drink too hot tea. Drinking tea may be better when it is hot, but hot tea is easy to damage the oral mucosa, and studies have shown that esophageal cancer is closely related to eating too hot food, so don't drink too hot tea.

There must be influence. Proper drinking is ok, but it is not enough to completely replace water.

Moderate drinking tea is very beneficial to human body, but if you drink too much tea at an unreasonable time, it will be harmful to human body. First, you shouldn't drink too much tea. Too much tea is easy to grow yellow teeth, and tea itself is diuretic. Drinking too much tea in autumn and winter affects sleep. The average amount of tea in autumn and winter is less than 500ml, which is about 2 cups of ordinary cups. You can drink more in summer Secondly, drinking tea and water after meals is the best time, which can not only eliminate fat and greasy, but also remove the odor in the mouth. In addition, when drinking tea at night, you should put less tea leaves, and don't make the tea too thick, otherwise it will excite your brain and is not conducive to sleep.

Water is one of the seven nutrients needed by human body, and the highest content substance in human body is water, and the proportion of water in human body is about 70%.

Water is the medium for absorbing and transporting nutrients and the carrier for discharging waste. The human body completes the metabolic process through the circulation of water in the body. People can eat nothing for a week, but they can't drink water for more than three days, otherwise their lives will be in danger.

Ordinary adults need about1500 ~ 2000ml (6 ~ 8 glasses of water) of water every day. In addition to the water contained in food, additional water is needed. Then, can we drink other drinks instead of drinking water directly? For example, tea is very popular in China.

To a certain extent, tea is not only beneficial to health, but also can replenish the body's water. But tea cannot completely replace water.

China is the origin of tea, with a long history of drinking tea and rich tea culture. Relevant research shows that tea contains many beneficial ingredients, so many people also regard drinking tea as a healthy habit. It is common for people who insist on drinking tea every day for several years or even decades in China.

However, drinking tea does not mean that there are no taboos, and there are many places to pay attention to.

1. Drinking tea after meals and before going to bed does more harm than good.

It is a bad habit to drink tea immediately after meals, because people digest a lot of food in our stomachs after meals. Drinking tea at this time will dilute the gastric juice and affect the digestion of food. If the tea you drink at this time is strong, the tannic acid contained in the tea will also affect the body's absorption of protein. In addition, drinking tea after meals will also affect the body's absorption of iron.

Drinking tea before bed is more important for early tea drinkers. After drinking tea before going to bed, it becomes very difficult for many people to fall asleep, which even seriously affects their mental state the next day. People with neurasthenia or insomnia should pay more attention.

It is suggested that you can drink tea half an hour after meals to avoid these problems.

2. Pay attention to alkaloids and other ingredients in tea.

The alkaloids contained in tea mainly include caffeine, theophylline and theobromine. But caffeine (caffeine) plays a major role. Caffeine has a good exciting center, relaxing smooth muscle, diuretic effect, and can refresh the mind. However, drinking too much will stimulate nerves and easily lead to insomnia. Excessive intake of caffeine for a long time will also cause calcium deficiency and increase the chance of osteoporosis.

In addition, caffeine has diuretic effect. Excessive drinking tea will increase urine volume, increase the burden on the kidneys, and may also make the body recessive dehydrated.

Tea polyphenols is another important substance in tea, which can scavenge free radicals in the body and achieve the effect of anti-oxidation and anti-aging, but it has great stimulation to the stomach. Excessive intake will cause gastrointestinal discomfort and lead to stomach problems. Some people who drink tea on an empty stomach may have some symptoms of stomach discomfort, which is also the reason.

Never think that the essence of tea is water.

Don't think that the essence of tea is water. You can just drink tea without drinking water. After all, tea also contains ingredients different from water, which is a unique rich ingredient in tea, and it can also be said to be a nutritional ingredient of tea. Most of these rich ingredients need the body to release water for metabolism, which is convenient for the body to absorb.

4, the normal amount of tea is not enough for the body to drink water every day.

Adults who drink tea should brew it 2-3 times a day (dry tea 10- 15g). If everyone drinks about 1500 ~ 2000ml of water every day, it is not enough to supplement the water needed by the human body just by drinking the tea brewed from these tea leaves. If you don't add tea, the tea at the back will be very weak.

I'm Brother Wang who shakes tea by hand. I am in the core producing area of Rizhao green tea.

Drinking tea every day is the standard for many old tea lovers, because there is no taste without tea, and some people may not understand it. Even drinking boiled water is hard to swallow, let alone being melodramatic. It is not surprising for some old people in Shandong that the habit of drinking tea has been formed for decades and it is difficult to change.

I make tea and drink tea every day. However, from the health point of view, I still suggest that you try not to drink tea half an hour before and half an hour after meals. Drinking tea before meals is easy to flush the space in the stomach. Half an hour after a meal is the peak time for digestion, and drinking tea is easy to cause bloating.

We have always advocated: drink healthy tea, drink healthy tea. One is behavior, the other is quality, and the two need to be organically combined.

I am three brothers Wang. You can say anything about tea.
