First of all, the "carbon dioxide in Coke" mentioned by the questioner is actually carbonic acid. As for carbon dioxide, this gas itself is also found in the air and is harmless to the human body.
Carbonated drinks (soda) products refer to drinks filled with carbon dioxide gas under certain conditions. The main ingredients of carbonated drinks include: carbonated water, citric acid and other acidic substances, sugar, spices, and some contain caffeine, artificial colors, etc. In addition to sugar, which can replenish energy for the human body, aerated "carbonated drinks" contain almost no nutrients. Common ones include: Coke, Sprite, and soda. Excessive drinking is harmful to the body.
1. Carbonated drinks can affect bone quality
Health experts remind that excessive drinking of carbonated drinks, the high phosphorus in them may change the body's calcium and phosphorus ratio. Researchers also found that compared with people who do not drink too much carbonated drinks, the risk of fractures in people who drink too much carbonated drinks is about three times greater; and while doing strenuous physical activity, the risk of fractures is also increased if people drink too much carbonated drinks. Possibly a 5-fold increase.
Experts remind that childhood and adolescence are important periods for bone development. During this period, children are very active. If the intake of high phosphorus and low calcium in food is unbalanced, coupled with drinking too many carbonated drinks, sufficient attention should be paid. Because it may not only have a negative impact on bone mass, but may also pave the way for future osteoporosis.
2. Carbonated drinks can damage cells
A latest British study shows that some carbonated drinks may cause serious damage to human cells. Experts believe that a common preservative in carbonated drinks can damage some important areas of human DNA, posing a serious threat to human health.
It is reported that the human damage caused by drinking carbonated drinks is generally related to aging and alcohol abuse, and will eventually lead to diseases such as liver cirrhosis and Parkinson's disease.
The focus of this study is the safety of sodium benzoate. The preservative, code-named E211, has been widely used in the global ￡74 billion carbonated drinks industry for decades. Sodium benzoate is a derivative of benzoic acid that occurs naturally in various berries and is used extensively as a preservative in many well-known carbonated beverages.
Peter Piper, professor of molecular biology and biotechnology at the University of Sheffield in the UK, is an expert in human aging. His test results proved that benzoic acid destroys an important region in human mitochondrial DNA.
Mitochondria are organelles in human cells and are called the "energy factories" in human cells. Their function is to use organic matter in cells as fuel, combine these organic matter with oxygen, and convert them into carbon dioxide. and water, while releasing the chemical energy in organic matter for use by cells. It decomposes ATP to provide 95% of the energy for the human body. When our muscles are contracting and when we are thinking, mitochondria are working all the time to provide energy for our neuron cells and muscle fiber cells.
Piper said: "These compounds can severely damage mitochondrial DNA and completely prevent mitochondrial activity. In other words, they make mitochondria go on strike." According to Piper, mitochondria can oxidize organic matter and release energy . If mitochondria are damaged, the cell can malfunction severely. Many diseases are associated with this disruption, such as Parkinson's disease and other neurodegenerative diseases.
3. Other hazards of carbonated drinks
People with diabetes should not drink carbonated drinks; they should not drink carbonated drinks before, after or during meals; they should not drink too much, because drinking too much will inhibit the body's metabolism. Beneficial bacteria destroy the function of the digestive system; long-term drinking can easily cause obesity and other diseases; excessive drinking of carbonated drinks can also increase the burden on the heart and kidneys, causing symptoms such as palpitation, fatigue, and frequent urination. At the same time, the digestion and sterilization ability of gastric juice will also be affected. And lowering it can easily cause gastrointestinal diseases.
In addition, heavy drinking can also lead to osteoporosis. This is because most carbonated drinks contain phosphoric acid, which can greatly affect the body's absorption of calcium and cause abnormal calcium loss. ; Carbonated drinks may increase the risk of esophageal cancer. This is because carbonated drinks dilate the stomach, which can lead to reflux of food that causes esophageal cancer. It is not advisable to drink too much ice drinks, otherwise it will lead to organ dysfunction and gastrointestinal mucosal vasoconstriction. A series of pathological changes such as gastrointestinal spasm, decreased secretion, etc. can cause diseases such as loss of appetite.

The above content is about the dangers of carbonated drinks, but Coke also has beneficial aspects to the human body:
Whether Coke affects health is a topic of great concern to many people. For many years, scientists There was endless debate among them. But as of 2018, scientific research has not found conclusive evidence that drinking cola in moderation is harmful to human health.
1. Coke can relieve fatigue.
Coke contains caffeine. Caffeine can temporarily drive away drowsiness and restore energy. It is clinically used to treat neurasthenia and resuscitate coma.
Caffeine can improve the body's sensitivity and concentration, accelerate the body's metabolism, improve the body's mental state and physical fitness, thereby eliminating fatigue.
2. Appetizer and food aid
Coke contains caffeine. Caffeine stimulates sympathetic nerves, stimulates the gastrointestinal tract to secrete gastric acid, promotes digestion, prevents bloating and gastroptosis, and promotes gastrointestinal hormones and peristaltic hormones to facilitate rapid defecation. Mix cola and tomato sauce half and half and smear it on the outside of the barbecue, so that the roasted meat will be very delicious. Use cola to mix noodles, and the steamed buns, steamed buns or fried twists and dumplings are very soft, crispy and have a fruity aroma. The caffeine in cola can also stimulate the gastric mucosa and promote gastric acid secretion.
To sum up, you must drink carbonated drinks like Coke in moderation. Too much will be harmful to the human body.
