Drinking coffee may be related to genes

The results show that the human liver produces several different proteins that break down caffeine, and the amount of these proteins is closely related to the body's tolerance to caffeine. The genes responsible for making these proteins include "CYPIA1" and "NRCAM". If these two genes are active in the body, people are more likely to drink coffee and are less likely to feel bad after consuming a lot of caffeine. The paper was published in the British Journal of Molecular Psychiatry on the 5th.
