Ultra-Processed Foods May Lead To Cognitive Decline - Neuroscience News

Summary: Ultra-processed foods have been linked to accelerated cognitive decline associated with aging and an increased risk of developing dementia.

But when evaluating how some diets may erode brain health as we age, research on the effects of consuming minimally processed versus ultra-processed foods has been scant – that is, until now.

It is not yet clear if the small difference in cognitive decline associated with higher consumption of ultra-processed foods will have a meaningful effect at the level of an individual person.

But they cannot rule out other lifestyle factors such as exercise, education, socioeconomic status, social connections, stress and many more variables that may influence cognitive function.

Lab-based studies in animals will make it possible to determine if ultra-processed foods are playing a key role in the development of cognitive impairments and dementia in people.
