Capsaicinoids are natural compounds found in chili peppers that give them their spicy heat. The most well-known capsaicinoid is capsaicin, which interacts with receptors in our mouths, creating a burning sensation. This unique property not only adds flavor to dishes but also has been studied for its potential health benefits, including pain relief and metabolism boosting. These compounds are responsible for the varying heat levels in different types of peppers, measured on the Scoville scale. While some people enjoy the fiery kick of spicy foods, others may find them too intense. Regardless, capsaicinoids play a significant role in culinary traditions around the world.
