Mint and Coke, Carbon Dioxide Gushing Out Every year, November 11 is dubbed “Bachelorette’s Day” by creative netizens. On this day, singles have plenty of reasons and unique programs to pass this happy or bitter day. “Boiling Coke”, a popular game in a bar in a cosmopolitan city in South China, was a big hit with some avant-garde bachelor party youths on “Hanukkah” in 2006. The game is played by eating mints while drinking a lot of cola and competing to see who can hold out long enough. The feeling of fullness, burping, bubbling, so that the “bachelors” feel very exciting. Recently, this so-called “brave man game” in some major cities across the country entertainment venues, universities and even primary and secondary school population has a spreading trend, there are many fans. The “brave man game” originally originated in foreign countries, some of the pursuit of mental stimulation players invented this game. Peppermint and cola were originally two completely separate food products, peppermint is acidic, containing sugar and food additives such as gum Arabic and gellan gum; cola is a recognized carbonated beverage, containing phosphates and carbonates. These two foods are not problematic in themselves and are relatively safe to consume alone. However, when peppermint candies meet with cola drinks, a chemical reaction occurs, and the heat released by the chemical reaction and additives such as gum Arabic and gellan gum in peppermint candies play a catalytic role to accelerate the release of carbon dioxide gas. In addition, the mint sugar surface contains a component that will decompose and destroy the tension on the surface of the liquid, resulting in the rapid release of a large amount of gas in carbonated beverages, resulting in a violent reaction and a large number of bubbles, presenting a “gush” of “boiling cola” phenomenon. The “Brave Game” participants are using the large amount of carbon dioxide gas produced when the mint and cola drinks meet to pursue excitement and challenges by producing fullness, burping and bubbles in the stomach for a short period of time. In fact, this “brave man’s game” is very dangerous. There is a video on the Internet: a strong foreign man wearing sunglasses ate about 14 peppermint gum in one gulp and then drank Coke, and then a lot of Coke spurted out from the corners of his mouth, and he fell to the ground, covering his stomach, in great pain. There were also reports of a Brazilian boy who died after eating Mentos and drinking Coca-Cola at the same time. From a medical point of view, “boiling Coke” can indeed bring many hidden dangers and deserves great attention. The exciting game, “safety door” is very hurt in the human stomach cardia and lower esophagus junction, there is a ring thickened esophageal sphincter, under normal circumstances in a state of retraction, like a “safety door”. When the food you eat passes through the cardia, the “safety door” opens to ensure that the food passes through and enters the stomach smoothly due to the contouring effect of the esophagus itself and the gravitational effect of the food, and after the food passes through, the “safety door” closes automatically to ensure that the food that enters the stomach and After the food has passed, the “safety gate” closes automatically to ensure that food and stomach contents such as stomach acid and pepsin do not reflux into the esophagus and damage it. Under physiological conditions, when there is too much gas in the stomach, the gas will pass through the cardia of the stomach, and the “safety door” can be instantly opened in the opposite direction to expel the gas in the form of belching and belching, so that the air pressure in the stomach will not be too high and cause stomach distension and other uncomfortable symptoms. The occasional and short-term opening of the “safety door” is not harmful to humans. However, the carbon dioxide gas produced by “boiling Coke” in a short period of time accumulates rapidly in a large amount in the stomach, and the air pressure in the stomach rises rapidly, and a large amount of gas is discharged rapidly through the cardia, which may cause the cardia to dilate rapidly and lead to tearing, causing cardia tearing syndrome. Because the cardia and lower esophagus contain a rich network of blood vessels, cardia tear can appear vomiting, vomiting blood, severe pain at the lower end of the sternum and other symptoms, serious cases can even be fatal due to tearing small arteries, vomiting blood. This is like a person wearing a suit, under normal circumstances the suit can only wear a sweater, and one day wear four sweaters and forced to wear a suit, it is very easy to cause the suit armpit lining tears and damage to the clothes, the two reasons are the same. A large amount of carbon dioxide gas produced in the stomach for a short time through the cardia discharge, in addition to causing the cardia tear, but also may make the lower esophageal sphincter of the “safety door” in a continuous open state, gas with gastric acid, pepsin and other gastric contents upward reflux, gastric acid, pepsin can cause damage to the esophageal mucosa, causing reflux esophagitis. Gastric acid and pepsin can cause damage to the mucous membrane of the esophagus, resulting in reflux esophagitis, heartburn, chest pain and other symptoms; regurgitant reflux up to the throat and inhalation through the trachea can also cause aspiration pneumonia, resulting in spasmodic cough, chest tightness and shortness of breath. In addition, the rapid increase of air pressure in the stomach can easily lead to rapid expansion of the stomach and damage to the gastric mucosa, causing acute stomach cramps, stomach pain, stomach distension and other uncomfortable symptoms. Patients with erosion of the gastric mucosa or peptic ulcers may also suffer from gastric perforation or upper gastrointestinal bleeding. The large amount of carbon dioxide produced by this “boiling cola” may also cause symptoms of carbon dioxide poisoning when the concentration is too high, such as dizziness, headache, tinnitus, blurred vision, weakness of the limbs, nausea, vomiting, panic, shortness of breath, shortness of breath, etc. Severe cases may even become unconscious. ”Boiling Coke” is not a “brave man’s game”, but a dangerous game, we are advised not to eat mint candies at the same time when drinking carbonated drinks such as Coke to prevent accidents.
