人在献出一定量血液之后,体内制造血细胞的“工厂”——骨髓组织,会加速制造血细胞予以补充。而制造血细胞的重要原料,是铁质及蛋白质。如果缺乏铁质和蛋白质骨髓将“难为无米之炊”。因此,献血之后,应当多吃一些富含蛋白质及铁质的食物,且应少饮茶。因为,茶叶中含有较多的鞣质,它可以与蛋白质及铁质结合,生成不易被人体吸收的物质,影响血 After people give up a certain amount of blood, the “factory” that makes blood cells in the body -- bone marrow tissue -- will accelerate the manufacture of blood cells to supplement. The important raw materials for the production of blood cells are iron and protein. If the lack of iron and protein bone marrow will be “difficult without rice.” Therefore, after blood donation, you should eat more foods rich in protein and iron, and you should drink less tea. Because tea contains more tannins, it can combine with protein and iron to produce substances that are not easily absorbed by the body and affect blood.
