Piaget Developmental Stages

Normal developmental process of human body is characterized by physical, psychological, mental, cognitive and behavioral changes. The development processes not only requires specific nutritional interventions but are also characterized by very specific growth changes (Berk, & Churchill, 1996). Jean Piaget, biologist and psychologist developed different stages of intellectual, cognitive and behavioral development from infant to adult age. This development stages are established on the basis of behavioral, cognitive and intelligence changes that are observed during these ages. These stages are named as Piaget Stages of Development which mainly comprise of four main stages namely Sensorimotor, preoperational, Concrete and formal operational …show more content…
First stage of infant nutrition is mainly dependent on breastfeeding for majority of nutritional requirement. But infants required Vitamin D in the form of supplement as breast milk is unable to provide this specific vitamin to infant body. As infant enter into toddler years, milk is complemented with iron fortified food like cereals, rice, fruits and vegetable puree which provide nutritional sources like calcium, iron and vitamin D. Child Nutrition from age 4 to 12 years become more complex and diverse as number of food items are introduced into child diet (Forbes, 2012). Along with whole grain, food and vegetables also comprise of important food requirement of this stage. Due to significant development years, the requirement of calcium, iron, vitamins, proteins and minerals increase manifold that need to be fulfilled by nutrition sources. At this stage deficiency of vitamin, protein or any other nutrition can result in developmental disorders that may affect the growth of children resulting in physical, mental or cognitive impairments (Rebouche, 1992). The final stage of adult nutrition required more calorie and carbohydrate intake in order to mat h the changing body system and rapid growth. As body mass is developing in these adult years therefore body required high amount of calcium and vitamin D. Similarly proteins …show more content…
However, this condition may be related any other medical condition or may be side effect of medications. Dementia is not a necessary condition of aging but memory loss may not be necessarily linked with dementia (Forbes, 2012). Similarly depression is not the result of aging rather it may develop due to different psychological factors. Similarly deterioration and decline of body function is natural consequence of aging but these processes can be slowed and reduced to some extent through nutritional interventions and physical
