Ultra-Processed Foods May Be Quietly Affecting Your Brain's Ability to Focus

In a study of 2,192 dementia-free Australians aged 40 to 70, higher ultra-processed food intake was linked to poorer attention and a higher estimated dementia risk.

The association did not extend to memory scores, suggesting different cognitive domains may be affected differently.

Researchers say the findings add to evidence that food processing level, not just nutrient content, may matter for brain health.

The observational study does not prove causation, but it may help shape diet guidance for aging populations, including interest in Mediterranean-style eating.
