In a well-known small teahouse, 68-year-old Aunt Li sits in her fixed seat every day, with a pot of freshly brewed green tea in front of her.
She chatted with her friends while drinking and said, "You know, I haven't drunk plain water for two years, I only drink tea, and I feel better!" However, two years later, Aunt Li died suddenly due to a heart attack, which is regrettable.
Aunt Li, a former primary school teacher, has a relatively leisurely life after retirement, and she is particularly fond of tea, whether it is green tea, black tea or other types, which has become almost her daily necessity.
In fact, after analyzing Aunt Li's living habits, the doctor pointed out that although tea is good, four kinds of tea need to be especially drunk less: strong tea, old tea, sweet tea and instant tea.
Although old tea, especially Pu'er tea that has been stored for many years, is of high quality, it may cause a lot of burden on the stomach and intestines of the elderly due to the fact that it may produce some metabolites of microorganisms during long-term storage.
Speaking of sweet tea, which is often referred to as a tea with a lot of added sugar, it is a potential health killer for people with diabetes or high blood pressure.
And instant tea, although convenient, may have various additives and preservatives added during processing, which undoubtedly adds additional health risks for the elderly who pursue a healthy life.
Reasonable tea consumption can help reduce the risk of cardiovascular and cerebrovascular diseases, and the antioxidants in tea are beneficial to the body. However, moderation is critical, especially for older people whose cardiovascular and cerebrovascular function may already have hidden dangers.
The right amount and type of tea can greatly reduce the potential health risks. On this basis, doctors suggest that the elderly should choose lighter tea when drinking tea and avoid drinking tea on an empty stomach so as not to cause stomach discomfort.
At the same time, attention should be paid to the replenishment of water, because although tea is good, it cannot completely replace the role of water, especially in maintaining the body's water balance.
After a health lecture in the community, a resident asked the doctor, "I heard that drinking tea can prevent cancer, is this true?" Can you drink more? ”
The doctor replied, "Indeed, the antioxidants in tea such as tea polyphenols do have a certain anti-cancer effect. It is recommended to keep the amount of tea between 3 and 5 cups per day and avoid overly strong tea. A balanced diet and a proper lifestyle are the keys to cancer prevention. ”
This answer made the residents who asked the question have a deeper understanding of how to drink tea scientifically. In an in-depth discussion of the relationship between tea and health, doctors also mentioned an issue that is often overlooked - fluoride in tea.
The doctor explained in detail that the fluoride in the tea helped to prevent tooth decay to a certain extent. However, drinking a large amount of high-fluoride tea for a long time will allow fluoride to accumulate in the body to a certain extent, which may cause dental fluorosis or bone fluorosis.
In response to this problem, doctors suggest that when choosing tea, choose fresh tea leaves as much as possible and moderate intensity, and should not be soaked for a long time.
In further interaction at the lecture, an elderly gentleman asked, "Doctor, I have high blood pressure, I heard that drinking tea can lower blood pressure, is this true?" ”
The doctor replied, "While green tea has certain benefits for high blood pressure, excessive caffeine intake may instead cause a rapid heartbeat or other heart problems. It is recommended that you limit your daily green tea intake to between three and five cups, and a balanced diet and regular physical activity are also very important to control high blood pressure. ”
The doctor further explained that in addition to adjusting the amount and method of tea drinking, it is also important for patients with high blood pressure to monitor the physiological changes brought about by tea drinking.
He suggested that patients with high blood pressure can use a home blood pressure monitor to regularly monitor blood pressure changes when changing their tea drinking habits, and observe the specific effects of different types and amounts of tea on blood pressure.
Doctors also mention that tea can be used as part of a healthy lifestyle, but it is not a substitute for professional treatment and advice from doctors.
Especially for patients with chronic diseases, they should adjust their diet and lifestyle habits under the guidance of a doctor to ensure that they do not affect their condition or have adverse reactions with medications.
In this way, the doctor not only answered the residents' questions, but also corrected some common health misconceptions, and helped everyone establish a more scientific and reasonable concept of life and diet.
