In the fast-paced modern life, middle-aged and elderly people pay more and more attention to the balance and health of body and mind. Tea, as a natural health drink, has become the first choice for many people's daily health with its unique aroma and rich nutrients.
But facing the mellowness of black tea and the freshness of green tea, many people find it difficult to choose. So, what is the difference between black tea and green tea? Which tea is more suitable for the health needs of middle-aged and elderly people? Today, we will reveal the answers to you one by one based on the latest research results of Peking University.
Black tea: warms the body and mind and promotes digestion
Black tea, made through a full fermentation process, is deeply loved by people for its unique taste and aroma. Black tea is rich in tea polyphenols, caffeine, carotene, potassium, manganese and other nutrients. Among them, caffeine can stimulate the central nervous system, accelerate blood circulation, and eliminate fatigue; potassium helps promote water metabolism in the body and plays a role in reducing swelling and diuresis.
In addition, the tea polyphenols in black tea also have the functions of antibacterial and anti-inflammatory and regulating the immune system. For middle-aged and elderly people, drinking black tea in moderation can not only warm the body and mind, but also promote digestion and relieve gastrointestinal discomfort.
Green tea: refreshing, antioxidant and anti-aging
Green tea, unfermented, retains a large number of natural ingredients in fresh tea leaves, such as tea polyphenols, catechins, vitamin C, vitamin E and various trace elements. The antioxidants in green tea, especially catechins, have strong antioxidant capacity, which can effectively remove free radicals in the body and delay the aging process.
In addition, the tea polyphenols in green tea also have many functions such as fresh breath, preventing tooth decay, and regulating blood lipids.
For middle-aged and elderly people, drinking green tea regularly helps to maintain good health and prevent a variety of chronic diseases.
Recently, a study by the School of Public Health of Peking University revealed the differences in health preservation between black tea and green tea.
The study followed up nearly 500,000 subjects for 10 years, and recorded the subjects' daily tea drinking and cancer incidence through questionnaires.
The results of the study showed that the overall risk of cancer increased for subjects who drank more than 4 grams of tea per day, but this conclusion was not significant after adjusting for confounding factors such as smoking and drinking.
It is worth noting that although there is no significant difference in the anti-cancer effect between black tea and green tea, each has unique health benefits.
Black tea:Studies have found that ingredients such as tea polyphenols and catechins in black tea are beneficial to cardiovascular health and can reduce the risk of heart disease.In addition, the warming effect of black tea can also help relieve common stomach discomfort in middle-aged and elderly people.
Green tea: The antioxidant content in green tea is higher, which has a significant effect on preventing cancer and delaying aging.At the same time, the tea polyphenols in green tea can also promote fat metabolism, help control weight and prevent obesity.
