Eggs
Due to the range of nutrients they contain, eggs are referred to as nature's multivitamin. They are especially abundant in vitamins and minerals that are important for brain health, including selenium, choline, and vitamin B12.
For example, choline is required for brain development and the production of the neurotransmitter acetylcholine, which is essential for memory storage and muscle function, while selenium is involved in coordination, memory, cognition, and motor performance. Additionally, eggs contain lutein, a carotenoid pigment linked to improved mental and visual function. To maximize the potential benefits, eating whole eggs is better than egg whites. In one research of 19 children and adolescents, eating egg yolks was linked to better short-term memory, attention, and learning scores than eating egg whites.
