Spicy foods may be regarded as beneficial for the body, such as by helping with weight loss. However, a new study has found that older adults should be mindful when consuming spicy foods as their cognition could be impaired.
The long-term study, which involved analysing more than 4,500 Chinese adults age 55 and above over a 15-year period, concluded that those who regularly ate more than 50 grams of chilli per day experienced faster cognitive decline. The decrease in memory and cognition is said to be particularly steeper for those who are slimmer.
According to the New York Post, among the tests included in the study published in the journal Nutrients were counting backwards, recalling a 10-word list and subtracting simple equations.
Dr Ming Li from the University of South Australia, which partnered with researchers at Qatar University for the study, said that consuming chilli was especially popular among Asian people. In China, for example, it is consumed every day by most adults in regions like Hunan and Sichuan.
Among the type of chilli examined by the researchers were dried and fresh chilli peppers, both of which contain capsaicin, which has long been regarded as metabolism and vascular health boosters.
