There is a folk saying that vinegar can sterilize and prevent colds, so some people pour vinegar into the pot to cook, and then close the doors and windows to let the vinegar evaporate, so as to prevent colds. Looking up the information, I found no research report that vinegar can kill the virus.

Many people think that vinegar has the function of disinfection and sterilization, probably because vinegar contains acetic acid. Acetic acid does have disinfection and sterilization effect at a certain concentration, but the effect is not very good. Even at high concentrations, it is not recommended. However, the concentration of acetic acid in vinegar is very low, which is far from the disinfection effect. Vinegar tastes good as a condiment, but it is not suitable as a disinfectant.

If the concentration of smoked vinegar is too high and the time is too long, the acidic gas emitted by smoked vinegar will stimulate the respiratory mucosa, especially leading to the onset or aggravation of patients with bronchitis, emphysema and asthma. Severe burns to the upper respiratory mucosa, especially for children, the elderly and asthma patients.

Reveal the efficacy of vinegar;

1, vinegar has no effect on softening blood vessels.

The main component of vinegar is acetic acid, and a small amount of various organic acids and amino acids are conducive to promoting gastric acid secretion. However, there is no scientific basis for drinking vinegar to soften blood vessels, promote digestion and reduce blood lipids.

Because vinegar enters the human body, it is normally metabolized by the human body through digestion and absorption. The acetic acid of vinegar can't directly enter blood vessels and bones, so it can't soften blood vessels. The acid-base environment in the body will not be easily changed because of the stimulation of external food. Therefore, it is also wrong that vinegar has the effects of enhancing immunity, anticancer and detoxification.

2, fishbone stuck in the throat, don't drink vinegar.

After the fishbone gets stuck in the throat, many people think that it can be softened by soaking in vinegar, so it is suggested to drink vinegar to soften the fishbone. But this idea is just taken for granted.

First of all, it takes a long time for fishbones to soak and soften in vinegar, and the vinegar we drink has a very short contact time with fishbones, so there is no time to soften them at all.

In addition, if drinking vinegar can soften and decompose fish bones, wouldn't normal esophagus and throat be damaged under the same intensity of stimulation? Therefore, if you get stuck in your throat by a fishbone, you should go to the hospital as soon as possible and take out the fishbone with the help of a professional doctor.
