Why some people crave coffee and chili while others can't stand them — and how genetics, evolution, and taste receptors play a role.

If you’re like many sleep-deprived professionals, your morning doesn’t really begin until that first cup of coffee hits. You scoop, you tamp, you brew — and suddenly, you feel semi-human again. But have you ever wondered why coffee tastes bitter to some and addictive to others? Or why chili peppers burn your mouth, yet people worldwide can’t get enough of them? The answers lie deeper than culture or habit — in your genes, your nerves, and millions of years of evolutionary strategy.
