#1673 Tea and coffee
Tea and coffee have hundreds of millions of fans around the world, which are respectively the “national drink” for western countries and eastern countries. Although people in both areas like drinking totally different things, tea and coffee actually contain the same substance: caffeine, which might be the reason that makes both tea and coffee popular among the world.
Caffeine would stimulate central nervous system in the brain, prolong the waking times and make your mind more clear and acute. It also makes you more concentrate with excellent refreshing functions, which makes it popular among office workers. Certainly, you cannot eat too much nice food. If you drink too much coffee and tea, it leads to iron-deficiency anemia. That’s because some matters in tea and coffee would inhibit the absorption of iron. There is a famous saying in China goes like this: You will feel wonderful if you have a cup of tea after meal. Although many people like to have tea after meal, heaving tea after meal would do harm to your body from a perspective of health because the uptake of matters necessary to one’s body such as iron and vitamins are from daily food. After a substantial meal, the food is still in one’s stomach. If one drinks tea immediately, it would be difficult for one to absorb the iron, which will bring no benefit to one’s body.
