Final answer:
In managing chronic lung disease in infants, an MCT oil predominant formula is often chosen due to the ease of absorption and metabolism of MCTs, which provide energy without needing as much oxygen. Nutritional strategies should be individualized and supervised by healthcare professionals.
Step-by-step explanation:
The nutritional management of an infant with chronic lung disease may involve specialized dietary modifications to meet increased energy demands due to the increased work of breathing and the body's efforts to repair and maintain lung tissue. The appropriate therapy would depend on the individual infant's condition, tolerance, and nutritional needs. However, use of an MCT oil predominant formula is often considered because medium-chain triglycerides (MCTs) are more easily absorbed and metabolized, providing a quick source of energy that does not require as much oxygen for metabolism as long-chain fats do. This can be particularly beneficial in the context of chronic lung disease, where oxygen is less available. Furthermore, MCTs do not require bile acids for digestion, which can be helpful if the infant has liver involvement or poor bile production secondary to their lung condition. While other formulas such as hydrolyzed protein formula might be useful in cases of allergy or malabsorption, and high fat, low carbohydrate formulas may be relevant for specific metabolic needs, it is important to understand that nutritional strategies for infants with chronic lung disease should be individualized and closely monitored by a healthcare professional, often including a dietitian.
