Final answer:
The correct dietary approach for breastfeeding clients includes consuming foods rich in calcium and protein to support lactation and provide essential nutrients for the synthesis of breast milk, which changes compositionally over time.
Step-by-step explanation:
The subject of the question pertains to the proper dietary considerations for a postpartum client who is breastfeeding. The correct statement that indicates the client understands the information regarding diet during breastfeeding is "I will include foods rich in calcium and protein."
This is because lactation requires additional nutrients to support the synthesis of breast milk, which undergoes changes in composition during the initial days postpartum and within the course of a single feeding. Early breast milk, known as colostrum, is rich in protein and antibodies to boost the infant's immune system, while mature breast milk contains a balance of fat, protein, and other nutrients. To sustain milk production and meet their increased metabolic needs, it is important not for nursing mothers to skip meals or excessively restrict certain macronutrients such as fats.
