When you consider the gut theme, maybe it is not always the best idea to fixate on "unhealthy" food or MSG or even the gut flora. Let us say that our nerve system is aleady in a hyper mode. Meaning that too much information is coming to the brain because it is not filtered. Most of us know how this feels in form of parestesias, pains etc. Every input we get on any surface of the body (or even a spontaneous nerve firing) will reach our brain unfiltered. Noe think of the guts as a huuuge surface. This surface can get a LOT of information. This is happening to IBS sufferers as well. They can (even painfully) FEEL movements in their guts, because they are aware of inputs "normal" people cannot feel. Now all this gut nerve information gets to the brain that is already overfed with information, and makes even more mess. So a Fibromyalgia diet in NOT on a first view a diet that will seem healthy. It is a diet to calm down the guts, to minimize any stimulus to the guts and therefore to the body. For people that are glutene sensitive, of course a big stimulus is glutene. But not for all. Usually the greatest stimuli are the raw , healthy foods, everything that has lots of fibers. Especially also onions. Feasting is a hard task for the body, I would not do that right now. Dairy products are a stimulus for many because honestly our bodies are just not made to digest milk as grown ups. So a diet that eliminates all stimuli consists of broth, cooked sugarfee oatmeal, soaked and cooked grains (they need to be slimy) and rice and potatoes. This is what I did in my first two weeks of my therapy, and it was...gross. But helped. Got me rid od my 16-year-old IBS I have been suffering from. And then slowly add back all those things you want to have in your diet, step by step. Start with well-cooked veggies and then built it up. Try to avoid sugar because sugar/insuline peaks are a stressor. At those points you add back the big suspects dairy and glutene, be extra-careful. If they give you problems, then it is not an issue of stimulus but maybe an intolerance. Be also careful with fruits (acid and sugar!). Soy is on of the biggest allergenes those days and often not the best substitute. You can try rice or almond milk instead. But only if you feel that dairy is not doing any good for you. In the end the goal is that you can keep your symptoms under control and live your life with as little limitations as possible. I was able to add back ALL foods to my diet, even some I was intolerant to before. It is mportant to understand that BFS is not a terrible deadly disease that we have to fight with tons of meds and stuff. It is a reaction of our body telling us " hey, I don't like your stress management and your lifestyle or maybe just that virus I had". I still think that the biggest key to healing BFS is to calm down and be happy, have a positive attitude and to listen to your body, what is good for it and what not. The reasons why people get BFS are various, and I guess so are the things that help it to calm down. But my answer is SLOWING DOWN. Taking time for yourself, and lower the expectations you have towards yourself. Learn to give up control and anxiety. If you do not do that, you can stuff whatever suplement into your body, eliminate any food from your grocery list, nothing will change. A major key to healing BFS is within the brain, not he body.
