Study Links Ultra-Processed Foods to Cognitive Decline

A study published in Alzheimer's & Dementia: Diagnosis, Assessment & Disease Monitoring analyzed over 2,100 individuals and found that consumption of ultra-processed foods is associated with declines in attention and cognitive function. The research indicated that even modest increases in ultra-processed food intake, such as adding a bag of chips to one's diet, can negatively affect cognitive abilities. Specifically, the study noted that for every 10 percent increase in ultra-processed food consumption, there was a measurable decrease in focus, reflected in lower scores on standardized cognitive tests measuring visual attention and processing speed. The study was led by Dr. Barbara Cardoso from Monash University, in collaboration with researchers from the University of São Paulo and Deakin University. Previous studies have also indicated a link between ultra-processed foods and increased risks of dementia and cognitive decline. Dr. Cardoso emphasized that the processing of food often introduces harmful substances, suggesting that the relationship between diet and cognitive function is influenced by the degree of food processing. Ultra-processed foods are prevalent in the diets of developed countries, contributing significantly to the total dietary energy intake in nations like the United States, Canada, and the United Kingdom. Health and Human Services Secretary Robert F. Kennedy Jr. has highlighted the issue of ultra-processed foods in his MAHA movement, advocating for the reduction of artificial additives in food products.
