According to the research of American scientists, many people hate coriander, which may be related to genes.

That is to say, people who don't like coriander have a gene in their bodies, which mainly exists on chromosome 11. This gene is very sensitive to aldehydes, and coriander contains a large amount of such aldehydes. At this time, when the gene is fed back to the brain, it shows discomfort and makes them feel very sick. This is why some people like to eat coriander, while others hate to eat it.
