Biological and environmental determinants of childhood obesity.
Childhood obesity reflects the confluence of three factors that minimize attention to internal physiologic satiety signals: the release of central opioids through ingestion of sweets and fats, which induces a preference for such foods; the phylogenetic quality of extending meals in response to environmental demands, as in work schedules, or through finding patches of agreeable food that are safe to consume (this is exacerbated in impoverished children, whose activity is limited); the determination of food preference through social interactions renders feeding systems open to external influences such as mass marketing and television advertising. Alternative feeding modes are presented based on studies of childhood food preferences and how children may be influenced to choose more balanced and healthier diets.
