Habaneros belong to the same Capsicum family of chili peppers that includes jalapenos, poblanos and bell peppers. Native to Central America, South America and the Caribbean Islands, habanero peppers are the hottest of all commercially grown chili peppers, making them a favorite with aficionados of spicy dishes. Habaneros boast more benefits than intense heat, however. They contain a high concentration of vitamins, minerals, dietary fiber and the compound capsaicin. Diets rich in the nutrients provided by habanero peppers may help prevent the development of a number of potentially serious medical conditions. If you suffer from digestive system problems like chronic heartburn or irritable bowel syndrome, talk to your doctor before eating habaneros.
