Psycho-Social Aspects of Nutrition Problems
Ingestion of foods is an evident prerequisite of metabolic processes of nutrition. For this simple reason, generally ignored, the study of feeding behavior belongs to sciences of nutrition. Feeding behavior is not determined by cognitive and voluntary factors. In human beings as in animal species, hunger and satiety, food preferences and aversions are physiological processes. For some time, the observational and experimental study of feeding behavior has demonstrated the regulatory nature of this process. Neuroendocrine mechanisms operate so that the control of feeding is integrated in the overall regulation of body energy and body composition. Most of nutrition problems and diseases result in man from defects of this physiological and regulatory control of eating behavior rather than metabolic disorders. Regardless of the availability of food sources, under-, over- or malnutritions result in fact from under-, over- or imbalanced feeding. Obesity or extreme leanness, protein deficiencies, alcoholis, and so on... are unknown in animals under the same condition of food disposal. They are consequences of specific diseases of human feeding behavior.
