I forgot to mention that the condition where your intestine walls become overly porous allowing things through that normally shouldn't pass is called 'Leaky Gut Syndrome.' Food sensitivity blood tests are not typically available through allergy specialists. The reason being that they are different in nature. Allergies are more severe because they evoke a direct immune response. Food sensitivities or intolerances are actually an indirect immune response where the antibodies and stress cause adverse effects. The only doctors that I have been able to find that offer the food sensitivity blood tests are homeopathic, which are normally licensed as chiropractors. Before you pick a homeopathic doctor, make sure to call their office and ensure that they are familiar with and can treat both 'Leaky Gut Syndrome' and food sensitivities.When I first started dealing with BFS, I saw my GP and even a neurologist. Both did there barrage of testing and then diagnosed my twitching as benign and most likely stress related. I had always been a skeptic of homeopathic medicine and I was actually pretty ignorant about it. My mom was always big into it but I never paid it much attention. Now faced with a crazy condition to which modern medicine had failed me in explaining, I decided to keep an open mind and give homeopathic medicine a shot. Luckily I did because it is the reason I am doing better today.When you go on the caveman diet, the hardest thing to get used to is not having ketchup, mustard, bbq sauce or even the bun for your burgers. I've gotten used to it and it doesn't bother me as much anymore. I use spices and seasonings to bring out the flavor in my foods and its actually pretty fun cooking new things now. I've also expanded my horizons in my food selection. I used to eat a lot of chicken, beef and pork and rarely ate fish. I find that I am eating a lot more fish and even more exotic meats like buffalo, lamb, goat, rabbit, duck and they're quite tasty! Its almost a necessity when you have to wait 4 days in between steaks or hamburgers. Like I said, its an adjustment at first, but now its like second nature. For dinner my wife and I will rotate in white potatoes, red potatoes, yukon potatoes, sweet potatoes (yams) and brown rice. We'll just dice them up and boil them in water for about 20 minutes, drain the water and your done. We used to buy the mashed potatoes in the box, but after reading the label of ingredients and preservatives, we're done with boxed foods. Its so much better this way and it really doesn't take that much longer. A new favorite of mine is to bake a sweet potato on the grill... yum! Anyway, my point is to experiment with new foods and you're likely to find some new favorites to supplement your old favorites, like pizza for me. Some of the most common food sensitivities are to wheat/gluten, dairy, and soy. The food companies put wheat in pretty much everything as a filler. Its even in those flavored rice packs you buy. Same with dairy, it is used in a lot of foods and all cheeses. Soy is in most condiments so we are exposed to that a great deal. The more common foods are safe ones to avoid at first because they are your highest likelihood of being your culprit. Listen to your body though. You can be sensitive to foods that are OK on the caveman diet. Some people are sensitive to rice. Others like me are sensitive to certain fruits and vegetables, like tomatoes and strawberries were for me. Hopefully you've caught your twitching early enough where you will be able to notice a significant difference once you cut your sensitive foods out. Just remember that the diet isn't permanent. Once you heal you will be able to enjoy those current problem foods again in moderation. Keep us posted how you are doing. By the way, where in Dayton are you? My parents live in Fairborn where my dad retired from the Air Force.
