Why do carbonated drinks make you burp? Why do carbonated drinks bubble?

Many people don't like to drink plain water. When they are thirsty, they drink a bottle of beverage. Carbonated beverages are especially popular among the general public, especially children. Drinking carbonated beverages is addictive, but because carbonated beverages make people burp, and carbonated beverages are accompanied by bubbles, so the stomach is not very comfortable. Why is this? Let's learn more about it below!

Why does drinking carbonated drinks cause burping?

In addition to a lot of water, carbonated drinks such as cola and Sprite also contain sugar, flavors, and a lot of carbon dioxide gas. Because the higher the pressure of the gas, the more it dissolves in the water, so when the factory makes carbonated drinks, it will increase the pressure to add a lot of carbon dioxide gas to the drink, and then seal the bottle. When we open the carbonated drink bottle, the air pressure outside the bottle is lower than the gas pressure inside the bottle, so the carbon dioxide dissolved in the water will be released, and small bubbles will emerge.

After we absorb the gas in carbonated drinks, our chest cavity expands, disrupting our normal breathing rate, and we start to burp and choke.

Why do carbonated drinks bubble?

1. The gas is carbon dioxide

The carbonic acid in carbonated drinks is a substance produced by the combination of carbon dioxide and water. Carbon dioxide gas is added during the processing of these beverages and dissolved in the beverages. It cannot be released when sealed. When the bottle cap is opened, the carbon dioxide gas will escape, and the bubbles on the cup are also this gas.

2. Changed solubility

When you open the bottle cap, the gas will escape because the pressure inside the bottle is relatively high. When you open the bottle cap, the pressure outside is relatively low, and the gas solubility decreases, so it will escape. Especially after shaking the bottle, the pressure inside the bottle becomes higher, and more gas will escape. Gas escapes in the cup because the room temperature is relatively high. When the temperature rises, the gas solubility will also decrease, and carbon dioxide will escape.

Three ingredients in carbonated drinks affect your health

Excessive carbon dioxide affects digestion

Although carbonated drinks come in a variety of flavors, the main ingredient is carbon dioxide, so you feel refreshed and stimulated when you drink it.

Some people say that carbonated drinks contain carbon dioxide, which may not be good for the human body. Professor Wang Lixin said that in fact, sufficient carbon dioxide in drinks can play a role in sterilization and inhibition of bacteria, and can also take away the body's heat through evaporation, playing a cooling role. However, if you drink too much carbonated drinks, it will not be good for the stomach and intestines, and it will also affect digestion. Because a large amount of carbon dioxide will inhibit the bacteria in the beverage while also inhibiting the beneficial bacteria in the human body, so the digestive system will be damaged. Especially young people like to drink soda and like the stimulation brought by soda, but if they drink too much at once, the released carbon dioxide can easily cause bloating, affect appetite, and even cause gastrointestinal disorders.

Too much sugar can harm your teeth

In addition to containing refreshing and stimulating carbon dioxide gas, the sweet aroma of carbonated drinks is also an important reason that attracts people to drink it. This strong sweetness comes from sweeteners, which means that the drink contains too much sugar.

Too much sugar in the beverage will be absorbed by the human body, which will generate a lot of calories. Long-term drinking is very likely to cause obesity. Most importantly, it will put a great burden on the kidneys, which is also one of the hidden dangers of diabetes. Therefore, people who already have diabetes should try not to drink it.

In addition, many teenagers, especially children, prefer this sweet taste. Professor Zhang Jiazhi said that this kind of sugar is not good for children's tooth development and is particularly prone to decay. A survey shows that the probability of tooth decay in 12-year-old children will increase by 59%, while the probability of tooth decay in 14-year-old children will increase by 220%.

Some people may choose sugar-free carbonated drinks for this reason, but Professor Zhang believes that although drinking carbonated drinks reduces sugar intake, these drinks are still very acidic and may also cause tooth decay.

Phosphoric acid causes osteoporosis

If you pay close attention to the ingredients of carbonated drinks, especially cola, you will find that most of them contain phosphoric acid. Usually people don't care about it, but this phosphoric acid will subtly affect your bones, and drinking carbonated drinks frequently will threaten your bone health.

The human body has requirements for various elements, so the intake of large amounts of phosphoric acid will affect the absorption of calcium and cause an imbalance in the ratio of calcium to phosphorus.

Once calcium is deficient, it will cause great harm to the physical development of growing teenagers. Calcium deficiency undoubtedly means slow bone development and osteoporosis, so data shows that teenagers who often drink a lot of carbonated beverages have a risk of fractures three times that of other teenagers.
