Allergy is a contemporary illness that does not appear to benefit from the preventative benefits of breast milk. Because of the recent and rapid growth in allergy, researchers believe that the composition of maternal milk has not been matched to the demands of allergy prevention. Modification of breast milk content may be the most effective method for preventing allergy development. This study will discuss current developments in allergy physiopathology and how breast milk variables may be particularly effective in interfering with allergy development in infancy. Breast milk variables have been shown in both rat and human research to influence parameters that are now known to be important for allergy physiopathology: baby gut barrier function, microbiota metabolite synthesis, and oral tolerance induction. Data from human cohorts suggest the possibility of modifying breast milk composition and influencing health outcomes in children through targeted treatments.

Breast milk should be able to treat allergy outbreaks as well as infectious illness if breastfeeding moms are given nutritional support.
