First, it's bad for your teeth.
A study published in General Dentistry, a clinical journal of the American Dental Association, pointed out: "Non-carbonated drinks and sports drinks are much more harmful to enamel than cola, and their harm is three times and 1 1 times respectively. Among them, high-energy drinks and bottled lemon tea are the most harmful to teeth. Compared with ordinary cola, the additives of sports drinks contain a variety of organic acids, which can decompose calcium and erode the enamel of teeth.
Canned or bottled iced tea has similar harm, and the damage to enamel is 30 times that of ordinary tea or coffee.
Dentists suggest that if you must drink sports drinks, drink them as soon as possible instead of sipping them. Or use a straw, because it can reduce the contact time between the drink and the teeth. Also remember, don't brush your teeth immediately after drinking. It is best to rinse your mouth with clear water first, and then brush your teeth after half an hour, otherwise it will do more harm to enamel.
Second, it's bad for the stomach.
You should pay attention to those who love carbonated drinks! Health experts warn that long-term consumption of carbonated drinks can lead to stomach pain at night.
Carbonated drink is a soft drink filled with carbon dioxide gas, which is often called soda in our life. Previous studies have said that drinking carbonated drinks for a long time is very easy to cause obesity and diabetes; Phosphoric acid in carbonated drinks will subtly affect human bones and lead to osteoporosis. This is an article published in Chest, a famous American medical magazine.
Abdominal pain during sleep has been ignored. Poor sleep quality has become one of the important factors that hinder modern people's effective work and life during the day. Experts in the study define that if you have stomach pains twice or more every month when you sleep, then you have the disease of sleeping stomach pains. According to a survey of 153 15 Americans, experts found that drinking too many carbonated drinks can cause stomach pain when sleeping. Because carbonated drinks contain more acidic substances, the acidity in the stomach increases, which in turn produces adverse stimulation and even damages the gastric mucosa; The released carbon dioxide is easy to cause abdominal distension, which may cause gastrointestinal dysfunction.
Third, lead to obesity.
On August 16, local time in the United States, Coca-Cola Company signed an agreement with American Beverage Association. According to this agreement, the products of Coca-Cola Company will be sold in American primary and secondary schools. The agreement mainly includes three restrictions: vending machines in primary schools only sell bottled water and 100% juice; Vending machines in junior high schools mainly sell bottled water, pure juice, sports drinks, calorie-free drinks and low-calorie juice drinks, while full-calorie drinks and juice drinks are only sold after class; In vending machines on high school campuses, the proportion of soft drinks does not exceed 50%.
This is the second time this year that Coca-Cola Company of the United States has encountered similar resistance in the American campus market. Three months ago, the Connecticut legislature passed a bill prohibiting the sale of high-calorie carbonated drinks and junk food to primary and secondary school students in the state from May 26 this year, because Coca-Cola made children obese. In addition, Pepsi and other soft drink manufacturers also suffer from "obesity".
Several European countries held activities to ban the sale of soft drinks on campus. Coca-Cola (China) Co., Ltd. said that it is unknown whether its plan to withdraw from the American primary school market will be introduced to China. Judging from their TV advertisements and various promotional activities, the target audiences of the two Coke companies tend to be people under the age of 20.
Obesity is caused by the fact that human energy intake is greater than energy consumption. Diet is an important factor leading to obesity. In the United States, soft drinks are considered to be one of the main reasons for the growing obesity problem. The diet and living habits of Coca-Cola or McDonald's in the United States determine the incidence of obesity in the United States by nearly 30%. It is understood that a can of 375 ml canned cola contains about 147 calories, which is equivalent to about one-eighth of the calories required by normal people in one day. According to the data of the Centers for Disease Control and Prevention, 0/6% of children and adolescents in North America/KLOC are overweight.
According to a research report in the British medical journal The Lancet this year, the average child who drinks a soft drink every day will increase the risk of being overweight by 60%. There was a cartoon that carbonated drinks and fast food were three times more harmful to Americans than cigarettes.
Obesity is a very realistic problem facing the whole society. Obesity in children may make them more susceptible to psychological disorders, hypertension, atherosclerosis, coronary heart disease, diabetes, fatty liver, sleep apnea syndrome and reproductive system dysplasia.
Fourth, it affects children's growth in development.
Carbonated drinks affect the body's absorption of calcium ions, so long-term drinking will definitely lead to calcium deficiency. For growing children, it is best not to drink carbonated drinks, but to drink some pure fruit juice drinks.
