Dementia risk rises with common food type millions eat every day, study suggests

A study published in Alzheimer’s and Dementia links ultraprocessed food (UPF) consumption to higher dementia risk and reduced attention in adults. Researchers from Monash University found that even a 10% increase in UPF intake correlated with cognitive decline, independent of a healthy diet like the Mediterranean diet. Experts warn UPFs may harm the brain through inflammation and poor nutrient quality.
