According to a study, a preference for strong coffee and a fondness for eating dark chocolate may come from your ancestors.
In fact, it’s not the taste of coffee that these people really like, but because they metabolize caffeine faster, they associate bitter taste with mental alertness.
These people metabolize caffeine faster and the stimulant effect wears off faster. So they need to drink more coffee.
When they equate the bitter taste with caffeine, that is, the stimulating effect, they desire a bitter taste when they need caffeine. According to scientists, this is a learned effect.
Thanks to this effect, those who like coffee bitter enjoy coffee and dark chocolate.
