In new research studying how genetic factors determine taste, scientists now believe they know why some humans prefer coffee, while others opt for tea.A paper published this week in the journal Nature Scientific Reports found that people who are genetically predisposed to like more bitter tastes typically choose coffee due to its higher content of tart caffeine.But, importantly for tea drinkers everywhere, that doesn’t make them right.As humans evolved we developed the capacity to detect bitterness as a natural warning system to protect the body from harmful substances. Evolutionarily speaking, we should want to spit that Americano straight down the sink.
