Chili peppers are the fruits of the Capsicum plant, which belongs to the nightshade family. There are many types of chili pepper, all of which have different heat levels.
In hot peppers, such as jalapeños, the fiery flavor comes from a compound called capsaicin. Studies have suggested that this compound can offer a wealth of health benefits.
A recent study reported by Medical News Today, for example, found that capsaicin might have the potential to halt breast cancer, while an earlier study linked the compound to a reduced risk of colorectal cancer.
