Those who had more than 50 grams of the spice a day almost had double the risk of memory decline and poor cognition, and the decline was even more significant for slim participants.
"Chili consumption was found to be beneficial for body weight and blood pressure in our previous studies. However, in this study, we found adverse effects on cognition among older adults," lead author Zumin Shi said in a statement.
Chili is one of the most commonly used spices in the world, but it’s particularly more popular in Asia, according to the study. It’s uncommon to consume more than 50 grams of chili daily in Western countries. However, “in certain regions of China, such as Sichuan and Hunan, almost one in three adults consume spicy food every day,” co-author Ming Li said.
The scientists revealed those who ate lots of chili had a lower income and body mass index and were more physically active than those who didn’t consume as much chili.
They also noted people with a normal body weight may be more sensitive to chili intake than overweight individuals.
The team now hopes to continue their studies to determine if reducing chili intake can lower dementia risk.
