Final answer:
During the first year of life, infants' nutritional needs change as they transition from a liquid-only diet to incorporating solid foods. Malnutrition in infancy can have serious consequences on the infant's health and development.
Step-by-step explanation:
During the first year of life, an infant's nutritional needs change as they transition from a diet of liquid-only to solid foods. In the first few months, infants rely solely on breast milk or formula for nutrition.
However, as they reach around 6 months of age, they start to introduce solid foods, such as pureed fruits and vegetables, into their diet. This change in nutritional needs is necessary to support the growth and development of the infant.
Malnutrition in infancy can occur if the infant does not receive adequate nutrition. This can have serious consequences on their overall health and development.
Some reasons for malnutrition in infancy include poverty, lack of access to nutritious food, and inadequate feeding practices. Malnutrition can lead to stunted growth, weakened immune system, cognitive and motor deficits, anemia, and other health issues.
