Question

Quizplus · Accepted Answer

Breastfeeding may prevent allergies through multiple mechanisms. Breast milk contains agents that can influence the gut microbial flora, such as bifidobacteria, which has been shown to reduce the risk of allergies. Breast milk also contains maternal immunity, including immunoglobulin A (IgA), which can help protect the infant from developing allergies. Additionally, breast milk contains maternal fatty acids and other immune factors that may also contribute to preventing allergies. Finally, breast milk has low levels of allergens compared to formula, which can reduce the risk of developing allergies. Therefore, all of the above mechanisms may contribute to breastfeeding's ability to prevent allergies.
