Chili peppers (Capsicum annuum) are the fruits of Capsicum pepper plants, notable for their hot flavor.
They are members of the nightshade family, related to bell peppers and tomatoes. Many varieties of chili peppers exist, such as cayenne and jalapeño.
Chili peppers are primarily used as a spice and can be cooked or dried and powdered. Powdered, red chili peppers are known as paprika.
Capsaicin is the main bioactive plant compound in chili peppers, responsible for their unique, pungent taste and many of their health benefits.
Chili peppers provide some carbs and offer a small amount of protein and fiber. Chili peppers are also rich in various vitamins and minerals but usually eaten in small amounts — so they don’t contribute significantly to your daily micronutrient intake.
