New research brings some good news for lovers of spicy(辛辣的) foods, after finding that eating hot red chili peppers might help to extend lifespan（寿命）.

Consuming hot red chili peppers might reduce death risk, say Chopan and Littenberg from the research team. In hot peppers, such as Mexico peppers, the strong flavor comes from a compound(复合物), which does not exist in sweet peppers or onions. Studies have suggested that this compound can offer a welth of health benefits.

A study of more than 16,000 people in the United States revealed that individuals who consumed red chili peppers had a lower risk of death from all causes over an average of 18 years than those who did not eat the spicy food. Compared with participants who did not consume hot red chili peppers, those who did were found to be at 13 percent reduced risk of all-cause death.

For example, a recent study reported by Medical News Today, found that the compound might have the potential to stop breast cancer, while an earlier study linked the compound to a reduced risk of digest system cancers. Still, the available data suggested that hot red chili pepper consumption was most strongly associated with a reduced risk of death from heart disease.

While the researchers are unable to identify the concrete compound by which red chili peppers might extend lifepan, the team says that it is likely due to the compound that is effectively against obesity(肥胖症).

Overall, the team says that these latest findings support those of the 2015 study, linking spicy food intake to reduced risk of death by showing “a significant decrease in death associated with hot red chili pepper consumption.” However, Chopan and Littenberg note that the earlier study was only conducted in Chinese adults, so the now research makes these findings more credible.
