This episode delves into the prevalence and pathophysiology of food allergies, emphasizing the difference between self-reported and diagnosed cases, with around 6% of both U.S. adults and children affected. The immune-mediated nature of food allergies and the various types of reactions they can trigger are discussed as well as the importance of clinical correlation with test results, because tests like blood, skin prick and patch tests can yield false positives.

Strategies to reduce the risk of food allergies, including early introduction of allergenic foods to infants are highlighted. The role of dietitians in managing complex cases involving multiple allergies, infants and comorbidities is emphasized.
