Chili peppers are a popular spice in many parts of the world and well known for their hot, pungent flavor. They are rich in vitamins, minerals, and various unique plant compounds. These include capsaicin, the substance that causes your mouth to burn. Capsaicin is linked to several health benefits, as well as adverse effects. On one hand, it may help promote weight loss and relieve pain when consumed regularly. On the other hand, it causes a burning sensation, which is unpleasant for many people, especially those not used to eating chili peppers. It’s also linked to digestive upset. It’s important to pay attention to your own tolerance levels when eating chili peppers. Using them as a spice may be healthy, but those who experience digestive distress should avoid them.
