Guest guest Posted July 24, 2003 Report Share Posted July 24, 2003 Suze- I don't have time to get into this at length, but no, they're not really mutually exclusive. The SCD theory holds that fermentation and bad organism overgrowth damages the intestine and leads to gluten sensitivity (and other allergies). Heal the gut, change the gut population, and proteins no longer get where they're not supposed to be and people can tolerate them again. This is in fact born out by experience. Wheat, though, and other grains too, will always potential problems, as they contain lots and lots of starch. It's true that the SCD breaks down in not considering that with adequate preparation, many peoples did in fact do pretty well with grains provided they also had enough animal protein and fat-soluble vitamins, but nobody's perfect, and the subject is at least partly beyond BTVC's scope anyway, since someone who's sick will have the best chance to heal, and will heal most quickly, eliminating all grains anyway. Certainly, though, if someone's going to add back some grains after healing, he'd do best to go the NT way. >----->do the gluten theory and SCD theory necessarily have to be >contradictory? i think both heidi and chris made some good points about how >they can both be accurate without the other being wrong. maybe that's what >you mean by " strict gluten theory " as opposed to a more " expansive " theory >that takes both gliadin/IGA issues and gut microbial fermentation into >account. - Quote Link to comment Share on other sites More sharing options...

Otherwise the two theories are compatible enough. Celiac researchers are mainly of the opinion that while IgE and IgG allergies DO go away (sometimes), IgA allergies seem to be hard-coded in the DNA, in the HLA genes. -- Heidi Quote Link to comment Share on other sites More sharing options...

IOW, both phenomena can exist in the world - it doesn't have to be an either/or situation. in some cases, maybe gluten is the initiator of damage and in others, bacterial dysbiosis *not* caused by gluten might cause the subsequent gluten problems.

Here, here! Good summary. One addition you made me think of: in celiac, the damage is to the very top part of the small intestine, just after the stomach, which is a spot where there is lots of undigested food, but not much bacterial action yet. Crohn's and IBD and the others are further down, where there is less undigested food and more bacterial by-products. So it would make sense to me that Crohns and the others are caused by bacterial by products, but upper gut damage is caused by reactions to the food itself. -- Heidi Quote Link to comment Share on other sites More sharing options...

" according to the above article. I was the one who said that ... someone did an experiment where they watched the villi react via endoscope when gluten solution was inserted. The villi flattened temporarily -- the " going to sleep " way my poetic nature coming forth ... The point of the study is that the villi *react* for a long time, maybe years, before any permanent damage shows up on a biopsy, so maybe it is a good idea to avoid gluten before there is real damage. -- Heidi Quote Link to comment Share on other sites More sharing options...

It sure does make sense because there are plenty of folks diagnosed as *celiacs* who do *not* get better on gluten-free diets but *do* heal on SCD. Letter posted below from one.

No, it it isn't a major whole in her theory any more than it is in the gluten-theory. In fact the gluten-theorists are quite divided on how to handle the glutenin issue and glutenins do NOT damage the villi in the way that gliaden does, even according to the people who oppose the consumption of them by celiacs and gluten-sensitives, such as the authors of Dangerous Grains. Nevertheless, non-gliaden gluten grains appear to damage the gut just as much or close to as much in a completely different way, in cuasing gut permeability but *not* causing atrophied villi, according to the authors of DG, and *other* grains obviously cause gut damage as well as made clear by the celiacs and other folks with gut problems who can't heal on a non-gluten diet but do heal when the cut out all the non-gluten grains, which even Heidi attests to as she has said while many folks do fine when they eliminate gluten others do much better if they eliminate starch or greatly reduce it. -Chris " After eight years of mysterious symptoms, dozens of doctors, gruelling, and often humiliating tests and general misery, no one could decide what was wrong with me. I discovered that because of my two sisters and my daughter had been diagnosed as celiacs, that I, too, should go on the gluten-free diet. Unfortuanately, for both my daughter, another sister and I, the gluten-free diet did not work. Some symptoms were arrested but none of us were thriving and we just weren't absoring food. We eventually found the Specific Carbohydrate Diet and it has been a godsend. I have never been healthier. My daughter, once a sickly (often whiney) withdrawn child with thin hair and dark circles under her eyes is outgoing, rosy-cheeked and happy. Everyone has noticed her thick shiny hair. In fact she ran a marathon this year and placed 15th out of 79 children. Last year she ran the same race (before the diet) and placed 53rd, arrived weepy, and slept all the way home in the car.

Guest guest Posted July 27, 2003 Report Share Posted July 27, 2003 OK, here is another monkey wrench ... gliadin seems to promote free-radical production in the blood -- which would account for higher levels of heart disease etc. Since maybe 1/5 to 1/3 of the American population is gluten sensitive, this would really throw off the health of the nation in general ... it also indicates that gliadin promotes IgG and IgE production. -- Heidi ========== ---------- Cytokine. 2003 Mar 21;21(6):270-80. Wheat gliadin promotes the interleukin-4-induced IgE production by normal human peripheral mononuclear cells through a redox-dependent mechanism. Dugas B, Dugas N, Conti M, Calenda A, Pino P, Y, Mazier D, Vouldoukis I. Isocell Nutra SAS, 53 bd du General Martial Valion, 75015 Paris, France. bdugas@... Increased levels of serum IgE have been described in gliadin-intolerant patients; however, biological mechanisms implicated in this immunoglobulin production remained unknown. In this study, we demonstrated that in vitro crude gliadins and gliadin lysates (Glilys) promoted the IL-4-induced IgE production by human peripheral blood mononuclear cells (PBMC), indicating that the biological process related to gliadin intolerance and/or allergy may lead to IgE production in vivo. It was found that crude gliadin and Glilys potentiated, after 13 days of culture in a dose-dependent manner, IL- 4-induced IgE production and, to a lesser extent, the IgG production, while they did not affect IgA or IgM productions. This promoting effect of gliadin and Glilys on the IL-4-induced activation of normal human PBMC was also observed on the early release (2 days) of the soluble fraction of CD23, suggesting its possible involvement in IgE potentiation. The promoting effect of crude gliadin and Glilys appeared to be indirect because they did not modify purified B-lymphocytes IgE production after IL- 4 and anti-CD40 monoclonal antibody stimulation.In addition, as revealed by luminol-dependent chemiluminescence, we demonstrated that crude gliadin and Glilys promoted a substantial production of free radicals by normal human PBMC, treated or not with IL-4. This redox imbalance associated with an increased IgE production led us to evaluate the effect of pharmacological antioxidants (N-acetyl-cysteine (NAC) and Cu/Zn-superoxide dismutase (SOD1)) on IgE production by human PBMC. The NAC and the intracellularly delivered SOD1 were found to suppress the IL-4+/-crude gliadin or Glilys- induced IgE production by normal human PBMC. Taken together, these data indicated that gliadin specifically enhanced IL-4-induced IgE production by normal human PBMC, probably by the regulation of redox pathways, and that this 'pro-allergenic' effect could be counteracted by natural antioxidants: thiols and/or vectorized SOD1. ---------- Biochim Biophys Acta. 1999 Jan 6;1453(1):152-60.

Coeliac disease (CD) is an inflammatory disorder of the upper small intestine in which gluten acts as an essential factor in its pathogenesis. Although it is generally accepted that cereal protein activation of the immune system is involved in CD progression, a non-immunomediated cytotoxic activity of gliadin-derived peptides on the jejunal/duodenal tract cannot be excluded. In this work, considering that (a) little has been reported about the intracellular metabolic events associated with gliadin toxicity, and ( an important role for free radicals in a number of gastrointestinal disease has been demonstrated, we investigated the in vitro effects of gliadin-derived peptides on redox metabolism of Caco-2 intestinal cells during a kinetic study in which cells were exposed to peptic-tryptic digest of bread wheat up to 48 h. We found that the antiproliferative effects displayed by gliadin exposure was associated with intracellular oxidative imbalance, characterised by an increased presence of lipid peroxides, an augmented oxidised (GSSG)/reduced (GSH) glutathione ratio and a loss in protein-bound sulfhydryl groups. Significant structural perturbations of the cell plasma membrane were also detected. Additional experiments performed by using the specific GSH-depleting agent buthionine sulfoximine provide evidence that the extent of gliadin-induced cell growth arrest critically depends upon the 'basal' redox profile of the enterocytes. On the whole, these findings seem to suggest that, besides the adoption of a strictly gluten-free diet, the possibility for an adjuvant therapy with antioxidants may be considered for CD patients.

The cells getting gluten and the cells not getting gluten would be under about the same amount of stress and have the same amount of bacteria, one would think. So I'd guess that in *that* case one can safely say the reaction is specific to gluten. I couldn't find anything about stress and IgA on Mercola's though. IgA is immunoglobulin, and there are lots of different types. Mostly it fights viruses. It makes sense you would produce more when you are under stress, probably more of the types you normally produce. But the IgA tests I'm talking about are specifically testing for IgA anti-gliadin antibody. You can test for IgA anti-casein antibody too, or IgA anti-cold-virus probably. The other test is for tissue transglutamase, which causes an auto-immune reaction which attacks your tissues -- that one isn't gliadin-specific at all, but it stops being produced when the person stops eating gliadin.

This is IgA in general though, not any specific type -- but if this is so, then a person would be LESS gluten reactive when they were under stress, because they would have less gliaden-reactive IgA as well as all the other types of IgA. http://www.mercola.com/2000/sept/10/hiv_gut.htm Emotions also tend to enter into gut health as if your adrenal are not functioning properly due to stress they will not make an antibody called secretory IgA which is responsible for local immune function in the gut. -- Heidi Quote Link to comment Share on other sites More sharing options...

Heidi, This could be interpreted from the SCD-theory. Wine is higher in simple sugars than beer. It is a fruit, starting with simple sugars from the get-go, and then it is fermented so if there are any disacharides in grapes to speak of there wouldn't be in wine. While barley is malted for beer, the other grains like hops aren't. The main problem with the interpretation would by why you can handle sorghum better than beer.

If I can get my hands on some sorghum malt ... I tried making some molasses beer and it actually turned out pretty darn good, except I made it too strong (I didn't use a recipe). You could get all the good stuff in molasses without the sugar ...

Ah, great minds are debating that question as we speak! Every so often someone pops up and says they have identified " the " sequence. Then other people disagree, or say there is not just one sequence. The beer companies say they are little peptides, just fragments, and not many of them at that. >the USDA database has the protein content of a 12 oz. beer at 0.30 grams. >i'd assume this is filtered/pasteurized beer. pretty small amount, but not >if you're gluten-sensitive, of course. It is a ridiculously TINY amount! And what's more, it is from SPROUTED barley, which has little protein left anyway. This is what makes me believe in homeopathy -- it must be the protein *holes* that cause the reaction. Seriously -- I just can't take beer at all, but wine (more carbs, more alcohol) is just fine, as is hopped kefir-beer made with molasses. But intellectually I still can't believe it. -- Heidi Quote Link to comment Share on other sites More sharing options...

Apparently some populations in africa have a very high incidence of CD. one abstract also discusses discovering some human gene byproducts that bear a striking resemblence to gliadin proteins. It's from the U. of Arkansas, and is part of their resource center on celiac disease for medical professionals: http://www.uams.edu/celiac/Jnl_Clb/genetics.htm Also on the same site, here's another interesting article: Gluten-Sensitive Enteropathy, More Prevalent than You Think http://www.uams.edu/celiac/review/GSE1.htm oh! aha...here is a reference to the amount of *peptides* on a chain that elicit an immune repsonse from this article. that would be minimum of 22 amino acids, with 2 being the minimum to form a peptide, but could be much higher: " Current theories hold that ingested 11-15 peptide long fragments of alpha-gliadin (and related) peptides bind with tissue transglutaminase (a ubiquitous intracellular enzyme) in the enterocyte. Alpha-gliadin is rich in glutamine. Transglutaminase deamidates the glutamine residues forming glutamic acid. Deamidation dramatically enhances the immunogenicity of the peptide creating epitopes that are recognized as foreign by host cell-mediated immunity.[2] " Suze Fisher Lapdog Design, Inc.

I found that out when I started growing some. Actually they are a HUGE vine that takes over your balcony, but pretty. >The main problem with the interpretation would by why you can handle sorghum >better than beer. Sorghum malt is supposed to be cheap, but it is considered to be contaminated with wheat usually. I can get sorghum seed, and try malting my own, but I haven't been that motivated yet! However, a bigger problem is that most commercial beer yeast is grown in barley -- so I'll probably wait for the new GF beer to hit the Seattle market (or at least mail order). I think beer is handled very differently that plain starches. -- Heidi Quote Link to comment Share on other sites More sharing options...

I have not followed the chemistry of the reaction as well as I should. There was a good article recently about the exact protein chain they were suspecting, but I can't find it right now ... -- Heidi Quote Link to comment Share on other sites More sharing options...
