I don't understand the previous "answer" on this post. I'm currently doing research into the link between healing CPTSD and diet. As a person who went from a crap diet to eating better and including the type of diet recommended in the research presented above, I can say that changing your diet is necessary for people regarding on if they have some kind of digestive disorder or not. Also, the term "diet" does not mean limiting what you eat to lose weight as you would on a "Jenny Craig diet" or something similar. Diet refers to what you put into your body on a regular basis to provide it nutrients. Fatty foods, high sugar foods, large amounts of caffeine, these will make CPTSD symptoms worse. Also, there are many people with CPTSD or another kind of anxiety disorder that already suffer from a digestive disorder for one reason or another because of the "mind and gut connection" outlined above. Please disregard the "answer" previously posted as it is incomplete and not evidence based.
