Drinking black tea can also help reduce stroke and heart disease? Research shows that the "1-drinking method" has the most obvious benefits
Is green tea healthier than black tea? British study: 2 cups of black tea a day reduces mortality
Is drinking green tea healthier than drinking black tea? Green tea is generally considered a healthy drink because it contains various antioxidant substances such as catechins and flavonoids. However, most green tea-related research comes from East Asia such as China and Japan. Is black tea intake also associated with mortality risk in areas where black tea drinking is dominant?
A prospective generational study based on the British Biodatabase investigated the amount of black tea consumed by 498,043 adults aged 40-69 years. After an average follow-up of 11.2 years, it was found that drinking 2 or more cups of black tea per day was relatively Mortality risk was somewhat reduced. The study was published in the journal Annals of Internal Medicine.
Does drinking black tea also have health benefits? Research says no added sugar and milk are best
Research data shows that compared to people who do not drink tea at all, drinking more than one cup of black tea a day can reduce mortality by 5% to 13%, especially for people who drink tea without adding sugar or milk. Drinking black tea produced the most consistent mortality benefit.
In addition, black tea intake is also negatively correlated with mortality from cardiovascular disease, ischemic heart disease, and stroke. The same conclusion was reached after ruling out genetics, caffeine metabolism and tea temperature. Research claims that drinking more than 2 cups of black tea per day is indeed associated with lower mortality.
Does high temperature affect the risk of esophageal cancer? Big data shows it’s safe to drink black tea
In addition, the intake of high-temperature hot tea is considered to be related to an increased risk of esophageal cancer. However, in follow-up reports, the overall proportion of esophageal cancer deaths in groups who often drink hot tea is quite small and almost negligible. Black tea should be safely included as part of a healthy diet.
The research team claimed that past studies on the relationship between drinking black tea and mortality from coronary heart disease, cancer, etc. had mixed opinions. However, through the large amount of data and long-term follow-up in the British Biological Data Database, the health benefits of tea can be extended from green tea to other areas. People who mainly consume black tea.
Drinking 2-3 cups of tea a day reduces the risk of premature death from heart disease and stroke
Many people are concerned about whether the benefits of different types of tea are different? According to data from Harvard University’s THCHAN School of Public Health, tea itself does not have macronutrients, but is rich in “polyphenols” and flavonoids. These phytochemicals have shown certain health benefits, including drinking 2-3 cups of tea a day, which can reduce the risk of Risk of premature death, heart disease, stroke and type 2 diabetes. The difference between green tea and black tea is that the former obviously contains catechins, while the latter contains more abundant theaflavins.
The polyphenols contained in tea are thought to reduce the risk of death from cardiovascular disease, including stroke. A study of 83,269 Japanese men and women found that drinking 2-3 cups of green tea per day reduced the risk of stroke by 14%, and drinking 4 cups per day reduced the risk of stroke. Green tea can reduce blood pressure by 20%.
In addition, regular consumption of green tea and oolong tea has also been shown to reduce the risk of high blood pressure. There are also small randomized controlled trials that have found that both black tea and green tea can reduce low-density lipoprotein (LDL); some studies have also found that drinking black tea has no significant effect on cholesterol levels.
Observational study concludes that drinking tea and ingesting polyphenols may still be beneficial to health
The results of observational studies on black tea and green tea are inconsistent. Harvard University’s THCHAN School of Public Health pointed out that the reason may be that the flavonoid content in different tea leaves varies greatly, and whether milk, honey, sugar, etc. are added to the tea leaves will affect the overall results. . For example, some studies believe that the protein and fat in milk will reduce the antioxidant capacity of tea.
Judging from the health benefits of “polyphenols” provided by tea, it is a healthier way to avoid drinking it with sugar, cream, and milk as much as possible.
