Protein-Calorie Malnutrition reviews the state of knowledge of metabolic phenomena in the syndromes embraced by the general term protein-calorie malnutrition (PCM), and places this new knowledge in perspective with the traditional descriptions of kwashiorkar and marasmus. The clarification it provides constitutes a benchmark for design of future programs of prevention, therapy, rehabilitation, research, or teaching. Highly noteworthy are the new advances in amino acid and protein metabolism; the enlightening evidence concerning lysine and carnitine; the evidences of derangements or deficiencies of the broad spectrum of nutrients from carbohydrates to vitamins and minerals; and the implications of these for recovery and therapy. This book includes papers on the following: the impact of age on amino acid requirements; the mechanisms of adaptation to low-protein intakes; the metabolic consequences of essential amino acid deficiency in higher animals; carbohydrate metabolism; vitamin deficiencies associated with PCM; and mineral metabolism in PCM. Other studies deal with the effects of malnutrition on endocrine function; liver function in PCM; the synergistic interaction of malnutrition and infection; and the treatment and prevention of PCM.
