We would like to complement the findings of the article “Daily Stress, Executive Functions, and Academic Performance in Elementary School Children” by Armstrong-Gallegos and Troncoso-Díaz, published in the Ecuadorian Journal of Neurology (Vol. 33, No. 1, 2024). Along these lines, we propose adding the perspective of the first two years of life, understanding that this is a critical stage in this process.
The brain development of children is rapid and crucial. Nutrition plays a fundamental role during these first years of life. Nutrients such as iron, omega-3 fatty acids, and B vitamins support important processes such as myelination and synaptogenesis. These processes, in turn, are key to executive function (EF) skills such as working memory, inhibitory control, and cognitive flexibility.1,2 Conversely, a lack of these nutrients can lead to long-term difficulties with self-regulation, impacting social and educational environments.3 Furthermore, glucose, as the brain’s primary energy source, when blood levels fluctuate too much, may make it harder for individuals to stay focused or control their impulses, which can affect their performance and interactions with others.
