International Hot and Spicy Food Day is celebrated on January 16 each year. It's a day for heat seekers to enjoy fiery dishes from around the world, from Sichuan hot pot and Indian vindaloo to Thai curries, Mexican salsas and Nashville hot chicken. Most spicy heat comes from capsaicin, a compound in chili peppers that tricks the body into feeling a burning sensation.
History of International Hot and Spicy Food Day
Chili peppers originated in the Americas, where people have grown and eaten them for thousands of years. After Christopher Columbus's voyages in 1492, peppers spread around the world through trade. Within a few centuries, they had become essential in cuisines across Asia, Africa and Europe, from Korean kimchi to Hungarian paprika.
In 1912, American pharmacist Wilbur Scoville created a test to measure pepper heat. His method diluted pepper extract in sugar water until tasters could no longer detect the heat. The result is the Scoville scale, measured in Scoville Heat Units (SHU). Bell peppers rate zero, while jalapeños range from about 2,500 to 8,000 SHU.
Today, scientists measure capsaicin with laboratory equipment, but the Scoville scale is still widely used. Superhot peppers such as the Carolina Reaper, named the world's hottest pepper by Guinness World Records in 2013, can exceed 1.5 million SHU. Who created International Hot and Spicy Food Day is not documented.
Why International Hot and Spicy Food Day Matters
Spicy food adds excitement and flavor to meals and connects people to many of the world's cuisines.
Capsaicin triggers the release of endorphins, which may explain why many people enjoy the burn and keep coming back for more.
Chili peppers also contain vitamins A and C, and spices can add flavor to dishes without extra salt.
