Coke is mainly composed of syrup and carbon dioxide gas. It is not nutritious to the body.

Drinking coke often will not only lead to obesity, but also lead to dental caries, osteoporosis and heart disease. It is also a potential risk factor for modern diseases such as diabetes.

Not to mention that additives such as pigments, spices and caramel contained in cola are harmful to human body, only caffeine is a substance harmful to health.

Coca-cola and grapes are popular drinks for Hong Kong people, but a survey conducted by the School of Dentistry of the University of Hong Kong shows that if you drink three cans a day for years, you may get toothache.

The School of Dentistry of the University of Hong Kong randomly selected 20 kinds of paper-wrapped, canned and bottled beverages containing acid and sugar, and found that 18 kinds of beverages had high acidity, which could dissolve the enamel protecting teeth, and the acidity of cola and grape was far higher than the index. The professor of dentistry pointed out that if you drink 1 liter of acidic and sugary drinks 1 to 2 years a day, the enamel on the tooth surface will be corroded by acid.

Prince Philip Dental Hospital receives nearly 20 complicated cases of teeth being corroded by acid drinks every year. Some patients drink several cans or bottles of cola every day, and almost all the enamel protecting their teeth is corroded by acid.

The pH value ranges from 1 to 14 degrees, and 7 degrees is neutral. If the acidity of the beverage is lower than 5.5pH, the enamel can be dissolved.

Caffeine is a drug, which excites the central nervous system, heart and blood vessels, and impairs memory.

In addition, for children, caffeine is irritating, which can stimulate gastric peristalsis and gastric acid secretion, causing intestinal spasm. Children who often drink coffee are prone to unexplained abdominal pain, and long-term excessive intake of caffeine will lead to chronic gastritis. Caffeine can dilate capillaries on the gastrointestinal wall, stimulate renal function, increase renal water flow, lead to polyuria in children, increase calcium excretion, and affect children's bone development. At the same time, caffeine can also destroy vitamin B 1 in children, causing vitamin B 1 deficiency.

A can of 355ml cola contains 65mg of caffeine, a can of 350ml oolong tea contains 80-120mg of caffeine, and a cup of instant coffee contains 85-200mg of caffeine. Normal people should not consume more than 200 milligrams of caffeine a day, otherwise they may be chronically poisoned. Children should stay away from coffee and drink as little caffeinated drinks as possible.

Moreover, some chemicals in cola, such as sodium, will raise blood pressure. Experts warn that high blood pressure will increase people's risk of heart disease, stroke and kidney disease, which must not be ignored.

1, cola contains caffeine, and it is addictive to drink for a long time.

2. Coke contains carbonic acid, and drinking too much is bad for your health. Because the human body is weakly alkaline

At its best.

3, there is nothing like protein, lacking nutrition.

4. Drinking it for a long time will make you fat, because it contains sugar.

5. In addition, when carbonated drinks represented by cola were first introduced, because of their good taste, the gas produced could bring out the heat in the stomach, giving people a feeling of comfort and excitement. After drinking habits, people will have a certain dependence on carbonated drinks. In fact, carbonated drinks have no nutritional value.

According to reports, the sugar in all kinds of carbonated drinks is high, and long-term drinking can easily lead to obesity. Coke contains sodium caffeine, which is similar to caffeine, and also contains preservatives. These ingredients are not good for your health and have no nutritional value. Drinking these drinks for a long time will definitely cause problems.

Experts suggest that you should drink carbonated drinks as little as possible, especially children, women and the elderly, and it is best not to drink them. "In fact, the best drink in China is our national drink-tea, especially green tea. Even drinking boiled water is better than drinking carbonated drinks. "

It is harmful for children to drink cola. Coke contains caffeine, and 1 bottle of 340g cola beverage contains 50 ~ 80mg caffeine. Some people have done experiments. Adults who take caffeine 1 g or more at a time can cause central nervous system excitement, rapid breathing, tachycardia, insomnia, dizziness and tinnitus. Even if 1 time is less than 1 g, nausea, vomiting, dizziness, palpitation, precordial pain and other poisoning symptoms will occur due to the stimulation of gastric mucosa. Children are more sensitive to caffeine than adults, so don't give them cola drinks.

Young girls drink cola to guard against osteoporosis. Studies have shown that soda can accelerate bone loss, especially for girls who love cola, and the probability of fracture is five times that of those who don't drink soda!

Experts pointed out that phosphoric acid in cola may be the cause of easy fracture, and phosphoric acid is harmful to bone, because phosphoric acid has adverse effects on calcium metabolism and bone. On the other hand, young girls who drink cola may have insufficient milk intake, which makes their bodies lack calcium, so they are prone to fracture.

Newlyweds should also drink coke carefully. Because most cola drinks contain high content of caffeine, caffeine can easily enter the fetus through the absorption of placenta in the body, which will endanger the brain, heart and other organs of the fetus, and also cause malformation or congenital diseases of the fetus. Therefore, experts suggest that newlyweds and couples who want to have children should not drink cola drinks except smoking. Even after the baby is born, nursing mothers can't drink cola drinks. Because caffeine can also enter the baby indirectly with milk, which is harmful to the baby's health.

Old people should not drink coke. Cola has diuretic effect, which can reduce the absorption of calcium by half. Old people often drink caffeinated drinks, which will aggravate the lack of calcium in the body, cause osteoporosis and fracture easily.

In addition, drinking too many caffeinated drinks will increase blood lipids and easily aggravate arteriosclerosis. Patients with hyperlipidemia and hypertension will drink more, which will accelerate the deterioration of their condition. For smokers, caffeine can easily mutate some tissues of the body and even lead to cancer cells under the action of nicotine mutagens. In order to avoid the above hazards, the habit of smoking and drinking cola should be changed.

Recently, the reporter learned that the world-renowned soft drink manufacturers Coca-Cola, Pepsi and other companies have reached an agreement on 1 25 this year to stop advertising drinks for children under 12 years old in the European market.

At the same time, these enterprises will stop selling soft drinks in primary schools. Its purpose is to cooperate with the European Union to carry out the campaign to eliminate adolescent obesity.

Marcos, member of the European Union responsible for health and consumer protection? Kyprianou warned not long ago that obesity has become one of the important factors leading to abnormal death in Europe. At present, more than 400,000 children in Europe are overweight. In the United States, soft drinks are considered to be one of the main reasons for the growing obesity problem. According to the data from the Centers for Disease Control and Prevention, 0/6% of children and adolescents in North America are overweight. According to the data of the Science Center for Public Interest in the United States, the average soft drink that American teenage boys drink every day contains sugar equivalent to 15 teaspoon of white sugar. In August, 2005, Coca-Cola and American Beverage Association reached an agreement that its products would be sold on American primary and secondary schools.

Coca cola:

There are no restrictions on the sale of children in China.

In foreign countries, Coca-Cola is actively restricted in primary and secondary schools, and advertising for children under 12 years old is stopped. What does it do for children in China? On February 17, reporters interviewed Coca-Cola China (Shanghai) Co., Ltd. (hereinafter referred to as Coca-Cola) respectively.

The telephone number of the information center of Coca Cola Service Department is prompted by voice, but the button of product quality is not set, so the reporter can only press the prompt of complaint. A young lady who didn't want to reveal her name said that she "wouldn't accept the reporter's inquiry", and she could only answer if the reporter complained and consulted as a consumer. This funny scene quickly turned the reporter into a consumer to consult. The reporter asked why the Coke Company stopped advertising children in Europe. Why didn't you stop selling Coca-Cola in primary and secondary schools in China? The staff member who claimed that Coca-Cola would not cause obesity in children said impatiently, "Children in China can't compete with other countries and are not afraid of obesity. Moreover, there are labels on the bottles of Kele, which are marked with product descriptions. Read the instructions before drinking, and you won't be obese. If a child is worried about obesity, no one insists that he must drink it. "

Subsequently, the reporter dialed the telephone number of Coca-Cola switchboard and asked to interview the relevant person in charge. The operator told the reporter that Coca-Cola has always refused to be interviewed by any reporter. If any media wants to interview, it will send an interview outline, and the company will decide whether to accept the interview within two weeks.

A gentleman from the Coca-Cola Customer Service Department told reporters: "The Coca-Cola Customer Service Department has not received any complaints about the obesity of the products, and the statement that advertisements should be stopped for children will not be adopted! 。”

Pepsi:

Coke that causes obesity in children should be stopped.

At 3 pm on February 17, the reporter interviewed the person in charge of the customer service department of Pepsi. The person in charge told the reporter bluntly that cola contains excessive white sugar, so excessive drinking of cola can lead to obesity, especially for teenagers and children.

She also told reporters that Pepsi products are currently being prepared for upgrading. A xylitol will soon replace the original white sugar. This sugar will not change the taste of cola, but it can definitely prevent children from becoming obese after drinking it.

Moreover, at present, there is a tendency to avoid advertising for children. In the selection of spokespersons for companies, from Guo Fucheng to Liu Xiang, most of them are advertisements for adults.

She also said that whether Pepsi will fundamentally cancel advertisements aimed at children depends on the big publicity atmosphere in China's cola market. All enterprises that may be involved in the cancellation must participate, and it is impossible for any one company to cancel.
