Regularly eating chili peppers can provide previously unrecognized health benefits, helping to extend human lifespan, a new study suggests.
According to preliminary research to be presented at the American Heart Association’s Scientific Conference in 2020, people who eat chili peppers may “significantly reduce their risk of dying from cardiovascular disease or cancer”.
While previous research has found that pepper consumption has anti-inflammatory, antioxidant, anti-cancer effects and regulates blood sugar levels due to capsaicin – the substance that gives chili peppers a characteristic hot taste, the study said. This study is the first large-scale attempt to compare reported pepper consumption with morbidity and mortality.
To evaluate the effects of chili peppers on longevity, researchers screened 4,729 studies from five leading global health databases: Ovid, Cochrane, Medline, Embase and Scopus.
These include four large studies that included exceptional health outcomes for participants with data on chili consumption.
This provided the team with health and dietary profiles of more than 570,000 individuals in the United States, Italy, China, and Iran, allowing them to compare the results of those who ate chili peppers against those who were rare. when or never eat them.
Compared to those who “rarely”; or “never” ate chili peppers, analysis found that those who ate them had:
- a relative 26% reduction in cardiovascular mortality
- 23% relative reduction in cancer mortality
- a relative reduction of 25% in all-cause mortality
“We were surprised to find that in previously published studies, regular chili consumption was associated with a reduced risk,” said senior author Bo Xu, a cardiologist at Cleveland Clinic. Overall muscle of all-cause diseases, cardiovascular disease and cancer The Heart, Cardiovascular & Chest Cancer Institute in Cleveland, Ohio.
“It highlights that dietary factors can play an important role in overall health,” he said.
But Dr. Xu warned: “However, the exact reason and mechanism that could explain our findings is currently unknown.”
“So, it cannot be concluded that eating a lot of chili peppers can prolong life and reduce mortality, especially due to cardiovascular factors or cancer.
“More studies are needed, especially evidence from randomized controlled studies, to confirm these preliminary findings.”
Dr. Xu also warns that there are some limitations to this type of research. The four studies reviewed included limited specific health data about individuals or other factors that may affect results.
Researchers also note that the amount and type of chili pepper consumed varies from study to study, so it is difficult to come to precise conclusions about the amount, frequency and type of pepper consumed may be related to the benefits health.
The team said they are continuing to analyze their data and aim to publish a full article in the right time.
