If successfully reintroducing corn after an elimination period, how long must symptoms be tracked after consuming a controlled portion?
Track symptoms for 48 hours.
The process of reintroducing a potentially problematic food like corn after an elimination period requires a methodical, slow, and incremental approach to gather personalized data. When reintroducing corn—ideally starting with a known, plain source like boiled corn in a small, controlled portion—the critical tracking window for observing any negative effects is specified as 48 hours. This window allows time for delayed intolerance symptoms (like GI distress) to manifest, which might not appear within a shorter, immediate observation period. If no reaction occurs during this 48-hour tracking period, the next step involves waiting an additional two days before trying a larger portion or a different processed product containing corn derivatives, ensuring any adverse response is correctly attributed to the reintroduction attempt.
