When obesity has become the world's disease source, health science articles are almost everywhere talking about what to eat and what not to eat, but diet, just talking about eating but not drinking, of course, is not enough, and talking about drinking should not just talk about drinking. Nowadays, Coca-Cola, Pepsi and other drinks are popular all over the world, and drinking Coke has almost become a fashionable thing, so the obesity caused by drinking Coke has attracted more and more attention. A study by the University of North Carolina in the United States found that if you are vigilant about the drinks you drink, you may lose 450 calories a day, thus losing almost a pound a week. Americans consume 192 gallon of drinks every year, about two liters a day, almost twice as much as 30 years ago. When we rely more and more on sugary drinks and eat more calories to get fat, someone will definitely say to you, why not drink Diet Coke instead? But before you choose Diet Coke, you really need to know the secret of Diet Coke. Just because Diet Coke is low in calories, you can't mistakenly think that it won't lead to obesity. Diet coke may have five fewer calories per serving than sugary drinks, but more and more studies show that drinking sugary drinks, even those made of saccharin, will make people love sweetness, that is, eating anything sweet and high in calories, such as sweet cereal, bread and dessert. Drink more sugar-free drinks and crowd out the healthy drinks we need. Sugar-free cola 100% has no nutrition. Everyone needs to consume about 2000-2500 ml of water (including water in rice) every day to meet the physiological needs of the human body. So much water is consumed every day, and drinking too many unhealthy drinks will squeeze out the opportunity to drink healthy drinks. So it's okay to drink a can of diet coke every day, but you won't have time to patronize those healthy drinks after drinking five or six cans at a time. The saccharin "aspartame" in sugar-free cola still has potential safety hazards. Sugar substitute aspartame is sweeter than real sugar 180 times. Some animal experiments have found that a large intake of this saccharin can lead to brain tumors and lymphoma. The FDA insists that this sugar substitute is safe, but the reported side effects include dizziness, headache, diarrhea, memory loss and emotional instability. Generally speaking, drinking too much diet coke is useless and may even hurt you. The best way to replenish water is to drink low-calorie and high-nutrient drinks, such as green tea, mineral water, low-sugar fruit juice, etc., and try to avoid drinking more soft drinks that swell your stomach.
