My opinion is that drinking tea is more beneficial than drinking coffee: coffee is one of the main drinks of westerners. It tastes bitter, but it has a special aroma and refreshing effect, so many people in our country like it very much. People who often work overtime and stay up late often use it to refresh themselves; Couples usually like the warm atmosphere of coffee shops. It can be said that coffee is also one of the main drinks in China. ≮ Efficacy ≯ People will inevitably be exposed to all kinds of radiation, such as light waves and electromagnetic waves. Over time, they will all cause harm to the body in different procedures. Drinking coffee in moderation can reduce this harm. A study by Japan Medical University found that a cup of coffee a day can inhibit liver cancer. Coffee contains caffeine, which can stimulate the central nervous system, promote the decomposition of liver glycogen and raise blood sugar. Moderate drinking can make people temporarily energetic and quick-thinking. Drinking after exercise has the functions of eliminating fatigue, restoring physical strength and invigorating spirit. ≮ Suitable for people ≯ Normal and healthy people can drink it. ≮ Dosage ≯ 65438+ 0-2 cups per day, up to 5 cups. ≮ Special tips ≯ Drink coffee with a glass of white water. Drink a mouthful of white water before tasting coffee, wash away the peculiar smell in your mouth, and then taste coffee to feel mellow; Because coffee has diuretic effect, drinking more white water can increase urination and promote renal function, so don't worry about getting angry. Drinking coffee should not be excessive. ≮ Health traffic lights ≯ People who often drink coffee should pay attention to calcium supplementation. People with cardiovascular diseases should drink less coffee. Older women often drink coffee, which will lead to osteoporosis and fractures. People with stomach problems and vitamin B 1 deficiency should try not to drink coffee. Excessive drinking by pregnant women can lead to fetal malformation or miscarriage.
