Final answer:
True, delaying the introduction of solid food until after 6 months can reduce allergy risks in infants, as a well-developed immune system is essential for preventing allergies, and breast milk provides protective antibodies.
Step-by-step explanation:
The statement that delaying the introduction of solid food until after the age of 6 months reduces the risk for allergy development in infants is generally considered true. The immune system needs time to develop properly, and introducing solid foods too soon can pose a risk for food allergies. The 'hygiene hypothesis' suggests that too clean environments may limit immune system challenges necessary for healthy development, potentially increasing the likelihood of allergies and immune disorders. Breast milk contains antibodies that protect an infant and contribute to immune system development, making exclusive breastfeeding for the first 6 months beneficial. It is during this time that colostrum plays a crucial role, as it helps to boost the newborn's immune system.
