Elimination diets can be an effective means of determining the potential for gluten sensitivity, but must be strictly adhered to for no less than 2-3 weeks and ideally at least 6-8 months to make a genuinely clear determination. Avoidance of gluten must be no less than 100% from all (even hidden sources) and not so much as even a single crumb of bread or trace contamination. Also, beware of cross contamination issues—where non-gluten foods may come into contact with gluten-containing foods via cooking/preparation surfaces and utensils in restaurants or at home (yes—this matters). The inflammatory effects of even trace gluten exposure in the brain especially and throughout the body can reverberate fully 6 months or more in sensitive individuals.
Shit tin of references in that blog post for you to go through.
Good work on reading the book. Dig the meal plan, re depression/moodiness, definitely look at getting more fat as nothing makes me grumpy like not having fat to munch on.
