After eating bananas, drinking sprite will vomit. Why?

Some people will vomit after eating bananas and drinking sprite carbonated drinks. Why?

First, let’s analyze the components of the two:

  • Sprite: A kind of carbonated beverage. Its ingredients mainly include: water, fruit Must, white granulated sugar, food additives (carbon dioxide, citric acid, sodium citrate, sodium benzoate) and edible essence.
  • Banana: starchy and beneficial fruit. Its chemical composition includes starch, protein, fat, sugar, ash, vitamin A, vitamin B, Vitamin C, vitamin E, etc. It also contains a small amount of 5- hydroxytryptamine, norepinephrine and dihydroxyphenylethylamine.

First of all, bananas, bananas, after chewing, are mixed with saliva to form a gel. After entering the stomach, they are mixed with gastric juice again to further form a thick gel banana mixture.

Then, under normal circumstances, the carbon dioxide contained in Sprite will precipitate rapidly after it enters the stomach. At this time, the carbon dioxide gas is obviously separated from the liquid in the stomach. After the carbon dioxide gas is continuously increased, the pressure on the stomach is strengthened, the diaphragm is stimulated to contract, and the stomach chalasia of cardia smoothly discharges the carbon dioxide gas.

In the case of thick and creamy gelatinous banana mixture in the stomach, after Sprite enters the stomach, the two are mixed, and the carbon dioxide contained in the mixture will be precipitated rapidly. However, due to the existence of banana mixture, the carbon dioxide gas cannot be separated in time after being precipitated, thus forming an aerated gelatinous mixture.

Due to the increase of carbon dioxide, the volume of this mixture expands rapidly, the gastric pressure is increased, the diaphragm is stimulated to contract, and at the same time, the gastric chalasia of cardia ejects the gas-containing colloidal mixture, i.e. vomiting.

If the stomach is stimulated strongly or continuously, vomiting will continue for a period of time until the stimulation is relieved or disappears.

This is why you vomit after eating bananas and drinking sprite.
