Spicy food is often blamed for stomach problems and acidity, but research suggests that chilli peppers may also offer benefits for heart health, digestion and longevity.
The possible advantages are linked mainly to capsaicin, the natural compound that gives chilli peppers their heat. It activates TRPV1 receptors involved in sensing temperature, spice and pain throughout the body. (The Washington Post)
Spicy-Food Eaters May Live Longer
A large 2015 study involving more than half a million adults in China found that people who ate spicy food six or seven days a week had a 14% lower relative risk of death than those who consumed it less than once a week.
Spicy-food consumption was also associated with a lower risk of death from cancer and heart and lung diseases. A later American study found that people who ate hot red chilli peppers had an approximately 13% lower risk of death during the study period than non-consumers. (The Washington Post)
However, these were observational studies. They show an association but do not prove that spicy food directly causes people to live longer. (The Washington Post)
Possible Benefits for the Heart
Several human studies have linked spicy-food consumption with a reduced risk of heart disease and stroke.
Small controlled trials suggest capsaicin may help increase HDL, commonly called “good” cholesterol, and may modestly increase calorie burning. (The Washington Post)
Spicy food may also help people consume less salt. A study of around 600 adults found that those who preferred hotter foods ate approximately half a teaspoon less salt per day and recorded lower blood-pressure levels.
Researchers suggested that capsaicin may intensify the perception of saltiness, allowing food to taste sufficiently salty with less sodium. (The Washington Post)
Does Spicy Food Damage the Stomach?
Contrary to a common belief, capsaicin does not appear to damage a healthy stomach lining.
It may reduce stomach-acid production and increase blood flow to the stomach, potentially offering some protection against gastrointestinal ulcers. (The Washington Post)
Spicy meals can still create a burning feeling in people with acid reflux because capsaicin activates heat- and pain-sensing receptors in the oesophagus. This sensation may feel like heartburn even when it is not caused by additional acid production. (The Washington Post)
Spicy Food and IBS
People with irritable bowel syndrome may have more TRPV1 receptors in the colon, making them more sensitive to capsaicin.
Spicy food can initially worsen abdominal pain in some individuals. However, small studies suggest that regular consumption over several weeks may desensitise these receptors and reduce chronic abdominal discomfort for certain people. (The Washington Post)
Responses vary considerably, so anyone whose symptoms worsen should not force themselves to eat spicy food for a possible health benefit.
Does It Worsen Haemorrhoids?
Although many people assume spicy food aggravates haemorrhoids, a placebo-controlled trial cited in the report found that capsaicin did not worsen haemorrhoid symptoms. (The Washington Post)
What About Cancer Risk?
The evidence linking spicy food and cancer remains mixed.
Most studies reviewed in the article suggested that capsaicin may have protective effects, while some research indicated that it could encourage tumour growth under certain conditions. Some studies have also associated frequent spicy-food consumption with an increased risk of stomach cancer, though others have not found the same result. (The Washington Post)
More research is required before chilli peppers can be promoted as either preventing or causing cancer.
Moderation Still Matters
People who enjoy spice can continue including it in their meals, especially as part of an otherwise nutritious diet.
Those who experience severe reflux, abdominal discomfort or other symptoms should limit chilli intake based on their personal tolerance rather than viewing spicy food as a required health treatment. (The Washington Post)
The dietary pattern with the strongest and most consistent evidence for long-term health remains a Mediterranean-style diet rich in vegetables, fruits, whole grains, legumes and other minimally processed foods. Chilli peppers can be part of that pattern but are not a miracle ingredient. (The Washington Post)
