Phase of reintroduction

  • The excluded foods will be gradually reintroduced one at a time, generally with a three-day interval between reintroductions. This enables you to watch for any potential reactions or symptoms.

Observation and monitoring

  • You will closely observe how your body reacts to each item during reintroduction. Observe any changes in symptoms, including gastrointestinal problems, skin responses, headaches, exhaustion, or mood changes.
