Do you like drinking tea? If so, your heart may thank you. Because a recent study found that drinking tea can reduce your risk of cardiovascular disease by 8%. For the fact that 60% to 70% of the body is water, it is enough to see the importance of water. For young people today, there are too many choices, such as various soft drinks, freshly squeezed juices, milk, and yogurt, which can bring greater stimulation to the taste buds. For some people, they have indirectly become the source of daily water supply, and have long forgotten healthy drinking water.
However, tea, which is in the middle, is a healthy drinking water resource and tastes better than boiled water. It is still deeply loved by people. The most important thing is its health-preserving effect. What are the health benefits of drinking tea?
Compared with other beverages, my country is the birthplace of the world's tea culture and the earliest hometown of tea manufacturing. It is called a healthy beverage by the world. It is not only low in fat and calories, but almost so low that it can be automatically ignored.
It can also promote people to drink, refresh, and resist oxidation. What is precious is that there are many active ingredients in various teas, including tea polyphenols, catechins, amino acids, etc., which have been found in cell experiments to have a positive effect on protecting human cardiovascular, anti-oxidation, and delaying aging.
Tea polyphenols: Tea is rich in tea polyphenols, which is a natural preservative. It has strong antioxidant and anti-inflammatory effects, can reduce blood viscosity, lower blood lipid levels, improve blood vessel elasticity, and prevent microvascular rupture. It helps to reduce the oxidation of low-density lipoprotein (LDL) and reduce the risk of atherosclerosis. Studies have shown that drinking 1-2 cups of tea a day can significantly reduce the probability of cardiovascular disease.
Caffeine: A moderate amount of caffeine can help dilate blood vessels and increase blood flow, thereby helping to lower blood pressure. Excessive intake of caffeine may cause adverse reactions such as arrhythmia, so the daily intake should be controlled within 300 mg, equivalent to 3-4 cups of tea.
Flavonoids: Tea is also rich in flavonoids, such as catechins and quercetin. These compounds have anti-inflammatory, lipid-lowering and immune-enhancing effects, and can effectively protect the cardiovascular system. Studies have shown that long-term tea drinking can reduce the incidence of cardiovascular disease by about 20%.
Nutrients: Tea includes minerals such as potassium and magnesium, which are essential for maintaining normal blood pressure levels and heart function. Drinking tea reasonably every day can provide some of the trace elements needed by the human body and further support heart health.
Some people say that since drinking tea has so many benefits, and there are so many teas on the market, According to the various industries of tea, there are many types of tea. Although all of them come from the same plant, they can be divided into six major categories due to different processing methods, including black tea, white tea, green tea, yellow tea, black tea, and oolong tea.
Taking the extremes of the two ways of making tea, there are black tea and green tea. Black tea is a fully fermented type of tea, while green tea is an incompletely fermented type of tea. What kind of tea is best to drink? It is recommended that you choose green tea.
Green tea is a kind of tea rich in tea polyphenols, which can resist oxidation and inflammation, protect blood vessels from damage, and lower blood lipid levels. Green tea is particularly beneficial to women's cardiovascular and cerebrovascular health, and can reduce the risk of myocardial infarction and stroke. Because it has not been fermented, green tea currently has the most antioxidants and has the best effect in protecting cardiovascular system. As for black tea, it also has its taste. People who have gastrointestinal discomfort after drinking green tea may try black tea.
In addition, when choosing black tea or green tea, you should pay attention to two common points. The first is that you cannot drink strong tea. Compared with light tea, no matter what kind of tea, in the case of excessive soaking, due to the high content of caffeine and oxalic acid, the more you drink, the more harm it may cause.
The second point is that people with anemia should pay attention to the way they drink tea. On the basis of not drinking strong tea, if you drink tea excessively, oxalic acid and iron will be fused, which may inhibit the body's absorption of iron. If you are iron-deficient and still want to drink tea, it is recommended to supplement it from other iron-rich foods.
