I have been gluten-free for about 5 years because I have IBS and food sensitivities to gluten products as well as to FODMAPs (Fermentable Oligosaccharides, Disaccharides, Monosaccharides And Polyols).
Unfortunately, being gluten-free has not helped my bipolar symptoms. A problem I am working with my medical provider is my poor nutrition because of the limited foods I can eat.
There is a caution to be careful about gluten-free diets because of nutritional problems that may result (e.g., see
Most People Shouldn't Eat Gluten-Free - Scientific American or
The Truth About Gluten).
