I have recently gone gluten free. It seems to me that doing so has definitely helped clear some of the brain fog. I am not a celiac and don't sufffer if I do eat some gluten. I know that some people are wheat sensitive as opposed to celiac. I'm not incredibly knowledgable on the subject but I got to thinking, from all the reading I've done here: is it possible that instead of being wheat sensitive that I am feeling benefit due to NOT ingesting folic acid that is a staple in fortified grain products? Any thoughts. It's really just curiosity on my part.
