Many parents dare not let their children drink tea, believing that tea will stimulate the child's central nervous system, make the child excited, and is not conducive to the child's development. There is also a view that tea polyphenols in tea can easily cause children to suffer from iron deficiency anemia. These views have some truth, but they are not absolute. Children's tea drinking should refer to factors such as age, physique, and season, and cannot be generalized.
Generally speaking, children under 6 years old should not drink tea, because children under 6 years old are not yet mature. Theophylline and caffeine in tea can indeed easily cause children to be overexcited, have a faster heartbeat, frequent urination, insomnia, etc. Tannic acid in tea can also affect the digestion and absorption of protein, thereby affecting children's appetite and growth and development.
Children over 6 years old can drink tea appropriately and reasonably. Generally, the daily intake is not more than two small cups, and it is best to drink it during the day. The tea soup should be light and warm. Be careful not to drink strong tea, and don't brew tea for too long. It is not suitable to drink tea before or after meals, otherwise it will affect the digestion and absorption of food. Therefore, it is best to let children drink tea half an hour after meals. Helping children develop the habit of drinking tea can also help prevent them from consuming too many soft drinks with high sugar content.
1. Prevent tooth decay
The role of fluoride: The fluoride content in tea is relatively high. Fluoride ions have a great affinity with the calcium in teeth and can become a kind of fluorapatite that is difficult to dissolve in acid, thereby improving the acid and caries resistance of teeth. This effect has a significant effect on preventing children's tooth decay.
2. Improve the body's immunity
Tea polyphenols and vitamin C: The antioxidant properties of tea polyphenols in tea and the vitamin C contained in tea can help improve the body's disease resistance, thereby enhancing children's immunity.
3. Promote digestion and increase appetite
Tea polyphenols and caffeine: Tea polyphenols and caffeine in tea can enhance digestive tract peristalsis, promote the secretion of digestive juices, and help digest food. For children, proper tea drinking can help digestion, increase appetite, improve picky eating habits, and also have the effect of reducing internal heat and relieving constipation.
4. Rich in nutrition
Multiple nutrients: Tea contains a variety of trace elements (such as phosphorus, potassium, magnesium, zinc, etc.), multiple vitamins (such as vitamin C), proteins, carbohydrates and other nutrients, which can provide rich nutritional support for children's growth and development.
5. Other benefits
Bright eyesight: Carotene in tea can be converted into vitamin A in the human body, which helps prevent night blindness. At the same time, vitamin C in tea is also beneficial for protecting eyesight.
Detoxification: Tea polyphenols in tea have a strong adsorption effect on heavy metals, which can reduce the toxicity of heavy metals to children.
Anti-radiation: Polyphenol compounds in tea can absorb radioactive isotopes, which helps to resist the harm of radiation.
Growth promotion: Most of the vitamins, amino acids, minerals and trace elements in tea can be dissolved in tea soup and used by children, which helps to maintain the balance of children's body and promote growth and development.
Although children have many benefits when drinking tea in moderation, tea also contains substances such as theophylline and caffeine, which can easily excite the central nervous system. Therefore, it is not recommended for children to drink excessively or drink strong tea to avoid affecting sleep and the development of the nervous system.
At the same time, the tannic acid in tea is easy to combine with minerals such as calcium, iron, and phosphorus, affecting the absorption of these substances. Therefore, parents should pay attention to the appropriate amount when giving their children tea, and avoid drinking tea immediately before or after meals.
Today, most teenagers are facing heavy learning tasks. The pressure of schoolwork can easily make them lack exercise and indigestion, leading to obesity. Parents' care or doting can also easily make children develop bad habits of gluttony and partiality. Excessive intake of high-calorie foods can also cause children to have indigestion and lack of certain nutrients.
Moderate tea drinking helps regulate fat metabolism, help digestion and absorption, strengthen small intestinal motility, promote the secretion of bile and intestinal fluid, and prevent obesity. Drinking tea can also supplement the minerals and other nutrients needed for growth, development and metabolism for teenagers, which is beneficial to their healthy growth. Teenagers drinking tea can also prevent tooth decay.
The elderly's physical fitness gradually declines, their digestive function declines, and their kidney function gradually declines. Therefore, when drinking tea, you need to pay attention to the amount of tea you drink, as well as the time and concentration of the tea.
Drinking a lot of tea or tea that is too concentrated can easily dilute gastric juice and affect the digestion and absorption of food; excessive intake of caffeine and other substances can easily lead to insomnia, arrhythmia, tinnitus, dizziness, and a lot of urination. Some elderly people with weak cardiopulmonary function are also prone to panic, shortness of breath, chest tightness, etc. after drinking tea. In addition, the elderly have weak gastrointestinal function. Drinking tea in the morning can easily cause gastrointestinal discomfort, and drinking tea at night can easily make the nerves too excited, thus affecting sleep and rest.
Pregnant women can drink tea in moderation, but not strong tea. The tannic acid in tea can combine with the iron in food to form a complex that cannot be absorbed by the body, which can easily lead to iron deficiency anemia. Excessive drinking of strong tea by pregnant women may cause pregnancy anemia, and will also leave the fetus with the hidden danger of congenital iron deficiency anemia. Pregnant women who drink too much tea can easily cause the fetus to absorb the caffeine in the tea, which will affect their growth and development. Caffeine is also not good for the health of pregnant women themselves, and it is easy to cause symptoms such as palpitations and insomnia.
