What is the recommended time gap between reintroducing new food groups during an elimination diet for suspected triggers?

Waiting at least two weeks between introducing a new food group.

When utilizing a structured elimination diet to precisely pinpoint a food trigger suspected of causing GERD symptoms, the reintroduction phase must be methodical and patient. The strategy involves removing a suspected food group entirely for several weeks to establish a baseline of symptom absence. Subsequently, to confirm the trigger, foods must be reintroduced one at a time, meaning only one new food category should be added to the diet during a specific window. The recommended waiting period between introducing these subsequent new food groups is at least two weeks. This extended, staggered approach ensures that if the symptoms return, the clinician and parents can confidently attribute the recurrence to the very last food introduced, accurately distinguishing a true dietary trigger from benign occurrences.
