I did food sensitivity testing and have eliminated my highly reactive foods (mushrooms, lemons, cow dairy, whey, eggs). Should I continue to leave these out until after the pathogen purge? How about moderate foods?

Yes, leave out the foods you reacted both high and moderately to, and then after you complete GT5, I’d say in 10-12 weeks, retest your food sensitivities and see if some of them are gone. Whichever ones are left are likely true sensitivities and therefore foods you should avoid. More often than not, tests come back with far fewer sensitivities after this process of gut healing.
