Egg intake and cognitive function in healthy adults: A systematic review of the literature

Abstract

Background: Cognitive decline is a growing public health concern, particularly in aging populations. Eggs are a widely consumed, nutrient-dense food containing choline, phospholipids, tryptophan, and omega-3 fatty acids, which individually support cognitive processes such as memory, attention, and neurogenesis.
