Regular use of spicy foods appears to be inversely associated with mortality.
A large 7 year observational study in China found all-cause mortality 10% lower among those who ate spicy food 1-2 days each week. Chili pepper was the most commonly used spice. The authors pointed out that the study design could not determine if it was spicy food or some other unknown factor that caused this benefit.
PositiveTip: Before you order up more chili peppers, you should wait for more convincing evidence.
