A reader wrote to us recently asking whether it is true that eating hot peppers can dull the taste buds. As pepper lovers ourselves, we found the question compelling. Scientists have not focused much research on answering it, however. We did find a rat study, and another reader objected to our conclusions.
Little Kids Eating Hot Peppers:
Q. I read your article suggesting that hot peppers could dull taste buds over time. I heartily disagree. Since I am originally from Mexico, I have been eating hot chili peppers since I was 5 years old (and I mean HOT peppers). I am 73 now, and my taste buds are not affected at all.
How did the rats (young or adult) inform the researchers if their taste buds were affected?
How the Study Was Done:
A. What a great question! The scientists actually noted the number of taste buds rather than their sensitivity (Omelian et al, Chemosensory Perception, Sep. 2016). The baby rats grew up to have fewer taste buds if they were exposed to capsaicin, which is what makes chili peppers hot.
Do Pepper Lovers Live Longer?
Research suggests that people who eat hot peppers regularly may live longer than people who prefer bland food (PLOS One, Jan. 9, 2017). This research was conducted in the United States. Previous research showed that Chinese people who challenge their taste buds with hot peppers also live longer (Lv et al, BMJ, Aug. 4, 2015). In particular, pepper lovers appear less likely to die from heart disease, respiratory disease or cancer.
