I have celiac disease and cannot eat grains, at least not any that I know of. Some celiacs can eat "gluten free" oats, meaning oats not contaminated by going through contaminated equipment, but I cannot eat any of them. And after developing celiac disease, I developed a cross sensitivity to corn, which is actually much worse (it does the same thing to me that wheat does) because, as it is not considered a "major allergen" -- the corn lobby is far too powerful for that; perhaps that is why there are only 8 allergens on that list as opposed to 10, which seems a reasonable number -- it is not labelled. You have to avoid literally hundreds of things that might be made using corn, such as maltodextrin or caramel coloring or other forms of sugar, even glucose, the glucose they use in a hospital. So, no, washing grains will not make them okay for me. We also have lots of GMO foods in the USA, as opposed to the protections they have in Europe. They are not labelled either. You are in South Africa? What is the case with GMOs there?
One very odd thing, they developed a wheat flour in Italy, using fermentation, to break down the gluten protein into something that does not trigger celiac disease. I thought certainly we would import this for all the desperate celiacs in this country. We import other Italian flour. But no, I have not seen a single trace of it.
And as far as allergies, I keep getting more of them. I have Ehlers-Danlos, which means messed up connective tissue and can contribute to leaky gut. So now I'm off eggs, beef, peppers (not sure if it's all peppers or just bell peppers), sorghum (a grain they use in gluten free breads) and some things I'm sure I've forgotten.
I have usually used oil of oregano, but I'm trying MMS this time because I also have ME/CFIDS, and have virus critters running around in me in higher than normal numbers, as my immune system is pretty much non-functional. Haven't had a real cold or flu since 1998, not because I'm healthy, but because my body can't mount a real defensive reaction, with fevers and sniffles and coughs and such. I might have the faintest hint of a sore throat, but it will be gone in one day. I think MMS can surely help with that. Years ago I used a very good colloidal silver, the best I could get, a whole case, taking it constantly. And, while I had been wearing reading glasses for 15 years by then, my vision cleared up COMPLETELY, and I had no need of any glasses for some time. I could not keep up the colloidal silver due to its expense, and my vision is getting pretty bad. I believe that is due to Cytomegalovirus. So I would like to clear out some of these nasties that have set up housekeeping in me for years and years.
