Huh. I wonder why humans would just happen to be born with the propensity to hate something good for them only to lose that propensity later in life. Like, would there be some evolutionary advantage? Maybe there are toxic plants that contain those bitter compounds and children who don't eat them survive to pass on their genes but adults who have lived and learned what not to eat don't need the same bitterness feedback, so humans evolved to lose it later? Or maybe I'm making stuff up and it's just one of god's practical jokes on humans like when we bite our tongue while chewing.
