A recent study suggests that increased consumption of ultra-processed foods may be associated with poorer attention and higher risks of dementia. While the findings do not establish a direct cause-and-effect relationship, they contribute to ongoing research into the impact of diet on brain health.

Dr. Darren Gitelman, a behavioral neurologist and the senior medical director at Advocate Memory Center, emphasizes that occasional lapses in concentration are typical and not necessarily indicative of a serious issue. However, he notes that attention plays a crucial role in learning, problem-solving, and memory formation, so significant changes in focus warrant further investigation.
Ultra-processed foods are typically industrially produced and often contain additives like artificial colors, flavors, sweeteners, and preservatives. Common examples include packaged snacks, sugary beverages, frozen meals, and processed meats. In the study, participants derived about 41% of their daily calories from these foods. Interestingly, even those following a Mediterranean-style diet exhibited poorer attention when their intake of ultra-processed foods increased.
Dr. Gitelman advises paying attention to both nutritious foods and limiting ultra-processed options in one’s diet.
To reduce intake of ultra-processed foods, individuals can make simple substitutions without the need to prepare everything from scratch. For instance, replacing sugary drinks with water, opting for fruits and nuts over packaged sweets, and choosing homemade meals with vegetables, whole grains, and lean proteins can be effective strategies.
Dr. Gitelman also points out that maintaining cognitive health as one ages involves more than diet; staying active, ensuring sufficient sleep, and managing health conditions like high blood pressure and diabetes are equally vital. There is no single strategy for supporting brain health, but daily choices, including dietary habits, can contribute positively over time.
