Spicy foods may be linked to a longer life, according to Dr Trisha Pasricha, a gastroenterologist at Harvard Medical School and health columnist for The Washington Post.
In a recent video, Pasricha highlighted research indicating that people who regularly consume hot red chilli peppers may have a lower risk of premature death than those who do not. However, she stressed that the evidence shows a correlation rather than proof that chilli peppers directly increase lifespan.
One frequently cited study, published in PLOS ONE in 2017, analysed data from more than 16,000 US adults and found that consumption of hot red chilli peppers was associated with a 13% reduction in mortality risk after adjusting for demographic, lifestyle and health-related factors. Researchers noted that the findings demonstrated an association, not causation.
Potential benefits for heart health
Pasricha said there is evidence suggesting spicy foods may offer several health benefits, particularly for the cardiovascular system.
According to the gastroenterologist, controlled clinical studies have shown that red chilli peppers may help raise levels of HDL cholesterol, commonly known as "good" cholesterol.
She also noted that people who enjoy spicy foods often use less salt because chilli peppers can enhance perceptions of flavour. Reduced salt consumption could potentially contribute to lower blood pressure levels.
Surprising effects on the digestive system
Pasricha also challenged the widespread belief that spicy foods inevitably worsen digestive problems.
Many people are advised to avoid chilli peppers if they experience heartburn or gastric discomfort, but she said the relationship is more complicated.
According to the specialist, capsaicin, the compound responsible for the heat in chilli peppers, activates some of the same receptors stimulated by stomach acid. This can create a burning sensation that resembles heartburn, even when acid production itself is not increasing.
She added that capsaicin may actually reduce stomach acid production, which could help protect against the development of gastric ulcers.
Moderation still recommended
Despite the potential benefits, Pasricha said consumers should not interpret the findings as a reason to overconsume spicy foods.
Her advice is that people who already enjoy chilli peppers can continue eating them as part of a balanced diet, while those who dislike spicy foods should not feel compelled to change their eating habits solely because of the available research.
The overall message, she said, is moderation rather than excess.
