Feeding the brain - The effects of micronutrient interventions on cognitive performance among school-aged children: A systematic review of randomized controlled trials.

Micronutrients are essential for brain development with deficiencies in specific nutrients linked to impaired cognitive function. Interventions are shown to be beneficial to children's mental development, particularly in subjects who were micronutrient-deficient at baseline but results on healthy subjects remain inconsistent. This systematic review evaluated the effect of micronutrient inventions on different cognitive domains. Studies conducted in both developing and developed countries, and trials that investigate the effect of both single and multiple micronutrient intervention were reviewed.
