Regular Chili Pepper Consumption Linked to Cognitive Decline
Previous studies have found that chili peppers may help with heart health, weight loss, and eye health. However, now a new study suggests that chili peppers may also increase the risk of cognitive decline.
Participants in the study included 4,852 adults who took part in the China Health and Nutrition Survey from 1991 to 2006. Their average age was 63. The researchers evaluated cognitive function in 1997, 2000, 2004, and 2006. A 3-day food record was used to assess chili intake.
The researchers found that participants who consumed more than 50 grams of chili peppers per day had approximately double the risk of memory decline and poor cognition compared to those who did not consume chili. The association between chili consumption and cognitive decline was stronger for those with a low BMI compared to those with a high BMI.
The study was conducted by researchers from Qatar University and the University of South Australia. It was published online ahead of print on May 27, 2019 in the journal Nutrients.
