About
Chili peppers (Capsicum) were domesticated in Mexico about 6,000 years ago and spread globally after Columbus's voyages. Within 100 years of European contact, chilis had transformed the cuisines of India, China, Korea, Thailand, Ethiopia, and Hungary — one of the fastest adoptions of any food in history. Today, chilis are the world's most widely grown spice crop.
The heat of chilis comes from capsaicin, which binds to pain receptors (TRPV1) that normally detect heat and acid — tricking the brain into perceiving burning. This triggers endorphin release, explaining why spicy food is both painful and pleasurable. The Carolina Reaper, at 2.2 million Scoville units, is so hot it can cause capsaicin-induced anaphylaxis.
