Objective:
Determine the influence of dietary factors on growth, physiological, psychological and cognitive development and functioning in children (from infancy through childhood). The overall goals of this study are to: 1) evaluate the effects of infant diet (breast-milk, dairy- and soy-based formulas, and monosaccharide supplemented formula) on physiological, behavioral, and cognitive development in infants and children; 2) determine the effects of diet composition, meal patterns, and meal frequency on brain function and behavioral dynamics that are important for learning and school performance in well-characterized normal and overweight school children; and 3) characterize neurocognitive function that contributes to or is a consequence of obesity in children, including brain-function correlates of food-seeking behavior.

Approach:
Children (infants, toddlers, and school-aged youths) will be studied longitudinally to evaluate the effects of infant diet (specifically, breast-milk, dairy- and soy-based formulas, and monosaccharide supplemented formula) on physiological, behavioral and cognitive development in infants and children. Nutritional status assessments, anthropometric measurements, urine and blood analysis, and measures of psychological, neuropsychological, and cognitive measures will be obtained and analyzed. The effects of diet composition, meal patterns, and meal frequency on brain function and behavioral dynamics that are important for learning and school performance in normal and overweight school children will be assessed using validated survey instruments and state-of-the-art research equipment. Neurocognitive function will be characterized that contributes to or is a consequence of obesity in children, including brain-function correlates of food-seeking behavior.
