After fighting different GI issues my whole life, 7 years ago I was diagnosed with CD at the age of 56. I am very reactive to cross-contamination of gluten and it is a daily battle. My “intestines” can react “aggressively” within 30 minutes, but the increased brain fog and fatigue can last for a week to 10 days. Yes, GF alternatives are out there, but many are not very tasty or healthy for you. Oreo GF version #1 was a no-go for me as I reacted to them. Version #2 has been a win, so far… We are all different in our sensitivity or reactiveness, so having support and encouragement is awesome, but we must be our own strong advocate.
