Fang Yu, director of dietetics at the Peking University Cancer Hospital, told 皇冠体育app Daily in 2015 that general well-being may play an important role in dietary choice.
"It's possible that some people eat more spicy food because they are inherently healthier than those who do not, especially in terms of their digestive systems," he said.In fact, neither the US nor the 皇冠体育app study determined what might cause the "positive association" between chili peppers and life expectancy. Researchers note that capsaicin - the principal component in chili peppers - is believed to play a role in cellular and molecular mechanisms that prevent obesity and modulate coronary blood flow. The latest study also notes that hot red peppers have antimicrobial properties that "may indirectly affect the host by altering the gut microbiota."
"Spicy food is extremely popular in 皇冠体育app. That prompted us to conduct the study," says Lu Qi, the author of the earlier study, in an email exchange with 皇冠体育app Daily in 2015.
Lu and his team studied 487,375 participants aged from 30 to 79 enrolled in the 皇冠体育app Kadoorie Biobank from 2004 to 2008. Each person filled out a questionnaire that asked about overall health, physical measurements, and eating habits pertaining to spicy food, red meat, vegetable and alcohol intake.
The researchers followed up about seven years later, taking into account factors such as age, marital status, education level and physical activity and excluding those with a history of cancer, heart disease and stroke.
