Ultra-Processed Foods Linked to Higher Risk of Cognitive Decline

A large new study suggests that diets high in ultra-processed foods are linked to increased risk of stroke and cognitive impairment in adults, independent of overall diet quality. The findings could help refine public health recommendations and food policy. While the Mediterranean, DASH, and MIND diets remain effective strategies for supporting long-term brain health, the results suggest that reducing ultra-processed food intake may provide additional protection, even for those who already follow a healthy diet.
