After dinner, cup of tea is an enjoyment for many people. In fact, drinking tea immediately after a meal is detrimental to health, and it also lays a hidden danger for anemia in the future. Huo Junsheng, director of the Food Science and Technology Division of the National Institute of Nutrition and Food Safety, National Center for Disease Control and Prevention, said: "Immediately after a meal, a large amount of water enters the stomach where the food is being digested, diluting the digestive juice secreted by the stomach, and thus affecting the stomach and the food. In addition, tea contains a lot of tannic acid, drink tea after a meal, will make the stomach digestible protein in the stomach and tannic acid combined into a non-digestible coagulation material, and affect the digestion and absorption of protein. What's more important is that tea interferes with the body's absorption of iron. After drinking a tea made with 15 grams of dried tea, the absorption of iron in food is reduced by 50%. Over time, it affects people's digestive function and even causes iron deficiency. Anemia." There are many people who like to have tea after eating, thinking that they can eliminate it. In fact, this is also bad for health. Director Huo told reporters: “Because a lot of tannic acid in tea will combine with protein to form tannic acid protein, this kind of material has astringent effect, which weakens intestinal peristalsis and easily leads to dry stool.†Director Huo stressed that in order to avoid the symptoms of anemia, it is appropriate to drink coffee or tea after emptying the stomach for about 1 to 2 hours after meals. It is usually possible to ingest green foods such as green leafy vegetables, red beans, and pork liver. To avoid the lack of hemoglobin. He suggested that it is best to drink black tea at night. Because green tea belongs to non-fermented tea, the content of tea polyphenols is relatively high and the irritating effect is strong. Black tea is a fully fermented tea and is weakly irritating. Tea should not be too thick. Fasting tea is easy to inhibit the secretion of gastric juice, impede digestion, and can even cause heart palpitations, headaches and other "tea drunk" phenomenon.
