Tea culture has a long history in China for thousands of years and has been deeply engraved in the marrow of the Chinese people. Drinking tea is also an indispensable part of our daily life. But whether to drink strong tea or light tea is a problem that tea lovers have been arguing for a long time without solving. People who love to drink light tea feel that the light taste can highlight the quality and aroma of the tea, while people who love to drink strong tea feel that strong tea is strong and tasty enough. Which in the end is it better to drink strong tea or light tea? Is it better to drink strong tea or light tea? Naturally, it is light tea. The reasons are as follows: 1, the caffeine contained in the tea is easy to make people addicted, in the case of drinking 2 to 3 cups of tea a day, it is easy to appear hypersensitivity, shortness of breath, anxiety and other phenomena. 2, the amount of flavor in the tea depends on the content of theophylline and aromatic substances. The theophylline content in light tea is relatively small, but enough to refresh the mind, invigorating but not overly excited, and the nutrients contained are not lower than strong tea. 3, strong tea will affect the absorption of nutrients. Strong tea also contains more tannic acid, tannic acid can be combined with the food protein vitamin B1 / iron ions, so that these nutrients can not be absorbed properly, easy to cause the body nutrient deficiencies and produce the corresponding symptoms, such as anemia, constipation, etc. 4, due to the relatively high content of caffeine in strong tea, such as regular strong tea, a large accumulation of caffeine can produce a strong excitatory effect on the entire central nervous system, so that the brain is in a state of hyperexcitation, especially at night drinking strong tea often seriously affect sleep. 5, often drink strong tea, due to the stimulating effect of caffeine will promote rapid heartbeat, accelerated blood flow, whistling speed, easily lead to arrhythmia or tachycardia. 6, often drink strong tea easy to hurt the bone. This is because the caffeine content of strong tea, and caffeine can inhibit both the absorption of calcium in the duodenum, but also accelerate the excretion of calcium in the urine. Due to the inhibition of absorption and accelerate the excretion of this dual role, resulting in a lack of calcium in the body, easy to induce calcium loss in the bone, over time, there will be osteoporosis, prone to fractures. 7, drinking strong tea can promote excessive secretion of stomach acid. Because the alkaloids in tea can reduce the activity of phosphodiesterase that can inhibit the secretion of gastric acid by the stomach wall cells, so that the stomach wall cells secrete a lot of gastric acid, over time, easy to form gastric and intestinal ulcers or make the existing ulcer surface difficult to heal. 8, excessive drinking of strong tea can also make infrequent tea or fasting tea drinkers appear “tea drunk” phenomenon, that is, after drinking tea feel palpitations, fatigue, irritability, dizziness, dizziness. 9, women in menstruation, pregnancy, childbirth, lactation often drink strong tea harmful. Menstrual period because of excessive blood loss, drinking strong tea is not conducive to the absorption of iron, easy to lead to anemia. Can also cause dysmenorrhea and prolong the period due to the stimulation of caffeine. Pregnant women drink strong tea, can not help but be prone to anemia. And is not conducive to the absorption of other nutrients. Although drinking tea is good, but you must pay attention to the habit of drinking light tea. There is also a need to drink tea every day in moderation, to avoid overdose.
