ABSTRACT
During the past couple of decades, researchers have demonstrated that the adult (developed) human brain is sensitive to normal variations in diet and nutrient intake; such variations, however, produce no clinical or biochemical evidence of malnutrition. Significant changes in macronutri ent (protein and carbohydrate) and micronutrient (B vitamins and iron) intakes have been found to influence the synthesis of brain neurotransmitters, the chemical messengers of the brain. The functional and behavioral significance of such diet-induced changes in brain chemistry remain to be established fully. The current research is examining the association between marginal intakes of the micronutrients and poor cognitive performance in humans as well as the effectiveness of nutrients in the treatment of neurological disorders (1).
