Zinc Nutrition in Children Who Fail to Thrive
An interactional causal model for failure to thrive (FTT), depicted in Figure 1, undergirds our clinical and research thinking with children who fail to thrive (Casey, 1983). Several aspects of these interactions have been addressed at this conference. The focus for this chapter is one corner of the model: undernutrition. Bithoney has stated that a common organic problem in all children who fail to thrive is one of malnutrition (Bithoney & Rathbun, 1983). We also believe that nutritional deficiencies play a major role in the pathophysiology of these children. Medical and nutritional scientists who evaluate children with malnutrition and FTT typically examine nutrition in terms of calories consumed, and the diet’s adequacy of the major food types of protein, carbohydrates and fat. The focus of this chapter will be on one specific nutritional deficiency: the trace mineral, zinc.
