Public chopsticks: public chopsticks are public chopsticks, that is, chopsticks used by everyone to hold food. They are put on a plate for everyone to use, but they can't be put in their mouths. They are designed for health problems.
Private chopsticks: corresponding to public chopsticks, you can only put them in your mouth, and you can't take food with private chopsticks in public areas.
Benefits of using public chopsticks:
China people's habit of not sharing food with each other will increase the risk of Helicobacter pylori transmission. Helicobacter pylori (HP) is the chief culprit of many stomach diseases, which is mainly transmitted through oral cavity and fecal mouth. If a family member is infected, the chances of others being infected will also increase, because there will be Helicobacter pylori in dental plaque and saliva of infected people, and chopsticks may become the transmission medium of germs if they are not eaten separately.
The International Agency for Research on Cancer under the World Health Organization lists it as the first carcinogen to induce gastric cancer. Because Europeans and Americans are used to eating separately, the infection rate of this bacterium is obviously lower than that of China. In addition to the diseases mentioned above, those diseases that often appear in anecdotal stories and are transmitted through blood and sex, such as hepatitis B or AIDS, are needless to say. In a word, meals will not spread such diseases.
