Many people like to drink a bottle of Coke when they are tired and thirsty. But I have to admit that drinking Coke did not quench my thirst (I’ll tell you why at the end of the article). Some people prefer sports drinks and drink a bottle from time to time regardless of whether they exercise or not. But the sports drink you buy may be "fake". We will tell you right away whether the common "sports drinks" on the market are real or fake. Special interesting knowledge points # Coke doesn’t quench your thirst, it’s actually related to the concentration of its ingredients Beverages can be divided into three types according to the concentration of ingredients: hypotonic, isotonic and hypertonic beverages. ✔ The concentration of hypotonic beverage ingredients is lower than that of human body fluids, which can quickly replenish water. Common mainstays, such as power drinks and water sports drinks, are hypotonic beverages; ✔ The concentration of isotonic beverage ingredients is close to that of human body fluids, which can quickly replenish water, energy and electrolytes. Most sports drinks are isotonic drinks, such as Gatorade, Jianjiao, etc. ✔ Hypertonic drinks have a higher concentration than human body fluids, which can replenish energy, but are not conducive to replenishing water, because drinking them will cause the water in human cells to move outside the cells (water osmotizes from low concentration to high concentration, and hypertonic drinks are high concentration), which is the so-called "dehydration", making people thirstier the more they drink. The cola and concentrated high-sugar fruit juice we usually drink are hypertonic drinks. Now you know why you feel thirsty after drinking Coke or other very sweet drinks! |
