Doctor Leonid Karev refuted the popular idea of ice cream as a product that can cause sore throats.
The current opinion that after ice cream can develop a sore throat is a myth.
“Ice cream cannot cause a sore throat,” Karev said in a comment to AiF.
The doctor recalled that a sore throat, in which characteristic sore throats occur, is an acute form of tonsillitis – a disease that cannot appear in connection with the food eaten. The cause of tonsillitis is an infection that lives in the nasopharynx and in many cases is chronic.
Karev added that if a person has chronic tonsillitis, hypothermia of the throat can cause its exacerbation with all the accompanying symptoms typical of an inflammatory process.
“Therefore, ice cream should not be consumed by people with chronic tonsillitis, especially in the acute stage.”
If a person is healthy, then eating ice cream in reasonable portions will only help harden the throat, the expert added. The main thing in such hardening is not to immediately eat a large piece of cold mass, you need to start with very small pieces that have already spent some time outside the refrigerator. after a big meal.
