Eat Hot Peppers for Longer Life

Like spicy food? If so, you might live longer, say researchers at the Larner College of Medicine at the University of Vermont, who found that consumption of hot red chili peppers is associated with a 13% reduction in total mortality -- primarily in deaths due to heart disease or stroke -- in a large prospective study. The study was published recently in PLoS ONE.

Going back for centuries, peppers and spices have been thought to be beneficial in the treatment of diseases, but only one other study -- conducted in China and published in 2015 -- has previously examined chili pepper consumption and its association with mortality. This new study corroborates the earlier study’s findings.

Using US National Health and Nutritional Examination Survey (NHANES) III data collected from more than 16,000 Americans who were followed for up to 23 years, medical student Mustafa Chopan and Professor of Medicine Benjamin Littenberg, M.D., examined the baseline characteristics of the participants according to hot red chili pepper consumption.

They found that consumers of hot red chili peppers have lower HDL-cholesterol in comparison to participants who did not consume red chili peppers. They examined data from a median follow-up of 18.9 years and observed the number of deaths and then analyzed specific causes of death.

“Although the mechanism by which peppers could delay mortality is far from certain, Transient Receptor Potential (TRP) channels, which are primary receptors for pungent agents such as capsaicin (the principal component in chili peppers), may in part be responsible for the observed relationship,” say the study authors.

There are some possible explanations for red chili peppers’ health benefits, state Chopan and Littenberg.

Among them is the fact that capsaicin is believed to play a role in cellular and molecular mechanisms that prevent obesity and modulate coronary blood flow, and also possesses antimicrobial properties that “may indirectly affect the host by altering the gut microbiota.”

Capsaicin is an active component of chili peppers. It is an irritant for mammals, including humans, and produces a sensation of burning in any tissue with which it comes into contact. Besides capsaicin, chilies contain antioxidants, including vitamin C and carotenoids, which might also help improve insulin regulation. Red chili peppers are high in beta-carotene, which is converted into vitamin A in the body.

“Because our study adds to the previous findings, chili pepper -- or even spicy food -- consumption may become a dietary recommendation and/or fuel further research in the form of clinical trials,” says Chopan.
