Thanks for sharing, Judalon! An elimination diet (to pinpoint allergies), certainly can be tricky. You can read my article about it for a bit more info, if you’d like! https://my.ps1000.com/how-to-do-an-elimination-diet-and-uncover-hidden-food-allergies/
One fascinating note is that symptoms of eating foods we are sensitive or allergic to sometimes don’t show up for 72 hours!!! And your doctor is absolutely right about rotating foods. Even the healthiest of foods should not be eaten every day, as it can put us at risk for developing an allergy, not to mention we are missing out on important nutrients from other foods.
Thanks for responding!
