Why does the cafe give guests a glass of lemonade or white water?
Go into the cafe and find a seat you like. Many cafes will serve a glass of lemonade or white water.
Why would a coffee shop do that? It was only after a deep study of the truth that we decided the necessity of "drinking water".
This glass of water makes sense:
Coffee and tea both contain dehydrated ingredients (caffeine and theophylline), which stimulate the central nervous system and have a strong diuretic effect on the kidneys. Therefore, after drinking these drinks, you also need to replenish water. Therefore, coffee and tea not only can not replace water, drink these drinks but also replenish some water appropriately. In addition, coffee has an exciting effect, even if the body is short of water, people do not feel thirsty. Chronic dehydration may occur day after day. Therefore, drinking coffee to replenish water is good for your health.
Second, if you still want to eat dessert cake, then water can lubricate the esophagus and prepare for dinner. Replenishing water before meals has the same meaning. Before entering solid food, drink half a cup (about 100 milliliters), which can be fruit juice or light tea at room temperature, or a small bowl of thick appetizer soup, which is a good way to nourish your stomach.
Third, lemon is rich in vitamin C, which has a variety of effects, such as antibacterial, improving immunity, assisting the production of bone collagen, often drinking lemonade, appetizer, relieving thirst and relieving heat; it can also remove phlegm, and the expectorant effect is stronger than orange and citrus. So we chose lemonade. However, because the pH value of lemon is as low as 2.5, it is not suitable for friends with excessive stomach acid and stomach ulcers. You can ask us to replace it with pure water.
Fourth, of course, if you come for coffee, drinking water can clean your mouth and eliminate some taste interference.
