Eating ultra-processed foods associated with poorer cognitive performance

Eating ultra-processed foods could impair cognitive performance in older adults, new research suggests.


According to the study published in the European Journal of Nutrition, older individuals who eat foods such as packaged snacks, breakfast cereals, choclates and pre-prepared pies, pizzas and pasta perform worse on standardized cognitive tests than their counterparts who do not consume such foods.


The researchers from Australia that such food items contain little to no whole foods and typically include flavorings, colorings, emulsifiers, and other cosmetic additives.


For the study, the researchers evaluated more than 2,700 participants who were 60 years old and above.


The participants were part of the National Health and Nutrition Examination Survey from 2011 to 2014. Each participant was asked to recall what they ate in a 24-hour period on two non-consecutive days. The participants then underwent standardized, validated cognitive tests, including one that assesses Alzheimer’s disease.


“Research indicates that diets that follow a Mediterranean Diet style, recognized by the high proportion of foods with anti-inflammatory and antioxidant properties, are associated with a reduced risk of age-associated cognitive decline and dementia,” said Barbara Cardoso, Ph.D., lead author of the study and a senior lecturer in nutrition, dietetics, and food at Monash University in Melbourne, Australia.
