Recently, there has been an emerging view which looks at the two-way relationship between nutrition, health, and psychosocial well-being. This concept is supported by studies on "positive deviance", a term used to refer to children who grow and develop well in impoverished environments where most children are victims of malnutrition and chronic illness (Zeitlin et al., 1990). The mechanism which helps to explain how psychosocial factors, such as the affect between mother and child, are associated with adequate growth and development: 'Psychological stress has a negative effect on the use of nutrients whereas psychological well-being stimulates the secretion of growth-promoting hormones. Pleasantly stimulating interactions can enhance the child's tendency to exercise its developing organ systems and hence to utilize nutrients for growth and development'.
