Study Links Ultra-Processed Foods to Cognitive Decline in Older Adults
A recent study conducted by Monash University, in collaboration with the University of São Paulo and Deakin University, has found a significant link between the consumption of ultra-processed foods (UPFs) and a decline in cognitive functions, particularly attention span, in middle-aged and older adults. The research, published in the journal Alzheimer's & Dementia: Diagnosis, Assessment & Disease Monitoring, involved over 2,100 Australian adults who were free from dementia. The study revealed that even a minor increase in UPF intake, such as consuming an additional packet of chips daily, could lead to a measurable decrease in attention span and an increased risk of dementia. The findings suggest that the degree of food processing, rather than the overall diet quality, plays a critical role in cognitive decline.
