What kind of tea is better for the elderly? I'll bring it to my grandfather when I go home during the Spring Festival. Please ask for details.

It is better for the elderly to drink tea lightly.

Tea culture has a long history in China, and the benefits of drinking tea are numerous. So many old people have developed the habit of drinking tea for health. However, Dr. Guo Yuan from the Department of Geriatrics, Peking University People's Hospital reminded that everything has two sides. Drinking tea is taboo and particular, especially for the elderly. If it is not controlled, it may be harmful to health. Generally speaking, the elderly should drink tea lightly but not strongly.

First of all, strong tea can easily lead to anemia and osteoporosis in the elderly. Strong tea contains a large amount of tannic acid, which can combine with iron in food to form compounds that cannot be absorbed by human body and inhibit the absorption of iron by human body. Strong tea not only inhibits absorption, but also accelerates excretion and calcium loss in the body. The higher the concentration of tea in the elderly, the greater the possibility of fracture.

Secondly, drinking strong tea may affect the sleep quality of the elderly. When people get old, there will be various natural changes in the quality of sleep, such as reduced deep sleep, easy to wake up at night and nap during the day. Drinking strong tea will disturb the autonomic nervous system of the human body, leading to emotional excitement at night, shortened rest time and increased blood pressure in the elderly.

Thirdly, drinking strong tea will increase the cardiovascular load, especially for the elderly. The heart function of the elderly gradually declines with age. Chaze is rich in caffeine, and drinking strong tea often makes people's heart beat faster, causing palpitation, palpitation, chest tightness, dizziness and other symptoms.

Finally, drinking strong tea is bad for the digestive system of the elderly. Tannic acid in strong tea can inhibit the secretion of gastric juice, hinder digestion and even cause gastrointestinal discomfort and loss of appetite. In addition, it can also cause abdominal distension and abdominal pain, and even lead to habitual constipation and duodenal ulcer.

Therefore, doctors advise the elderly not to drink strong tea, and stay away from strong tea before meals, in the afternoon and before going to bed. It is best to drink tea about 20 minutes after meals, which can help digestion, relieve greasy and clear the stomach. In the category of drinking tea, black tea should be the main tea, and oolong tea can induce diuresis, which is also very suitable for the elderly. But green tea is not suitable for the elderly who are cold, weak in gastrointestinal tract or constipated.
