Healthy Gut Microbes May Prevent Celiac?

Intestinal Microbes Health Help YOUR Health

Those Beneficial "Bugs" In the News Again

I was just reading an article discussing studies by Oregon State University researchers into how gut microbes are closely linked to proper immune system function and other health issues. This may not be "news" to many readers, but it is further confirmation of the importance of maintaining a healthy GI tract — and it sure makes me wonder even more about the potential ill effects of using antibiotics to treat conditions, especially when not needed (since, antibiotics kill off the "good" bacteria in your gut as well as the "bad" bacteria in your body).

[Note: my next closely-related article is about Probiotic Levels in Yogurt and Kefir (billions and trillions of those beneficial bugs!)]

I have written here in the past about other studies connecting antibiotics and celiac disease, and this latest study deepens my concern. As quoted from the article I am referring to,

"In a healthy person, these microbes in the gut stimulate the immune system as needed, and it in turn talks back," Shulzhenko said. "There's an increasing disruption of these microbes from modern lifestyle, diet, overuse of antibiotics and other issues. With that disruption, the conversation [the "crosstalk" between gut microbes and our immune system and metabolic processes] is breaking down."

And, it is not just antibiotics that are brought into question in this study.  How about dirt... or, should I say our lack of exposure to dirt?  Yes, we (modern humans) are probably making things worse by being TOO "clean":

"Appropriate sanitation such as clean water and sewers are good. But some erroneous lessons in health care may need to be unlearned -- leaving behind the fear of dirt, the love of antimicrobial cleansers, and the outdated notion that an antibiotic is always a good idea. We live in a world of "germs" and many of them are good for us."

Our immune systems have developed over the course of human history to function optimally by adapting to natural exposures to varied bacteria (in things like dirt) that modern sanitizing products wipe out (externally).  And, antibiotics are essentially "sanitizers" that wipe out internally-present bacteria (including the plethora of "good" ones that we need to function properly).

Celiac and Other Conditions : the Role of Gut Microbes

The article mentioned Celiac Disease (i.e., autoimmune gluten allergy that requires us to be on a gluten-free diet) as well as other conditions where there is an interplay of gut-microbe-crosstalk and our bodies:

"An explosion of research in the field of genomic sequencing is for the first time allowing researchers to understand some of this conversation [between gut microbes and our immune / metabolic systems] and appreciate its significance, Shulzhenko said. The results are surprising, with links that lead to a range of diseases, including celiac disease and inflammatory bowel disease. Obesity may be related. And some studies have found relevance to depression, late-onset autism, allergies, asthma and cancer."

Seems like more and more evidence is piling up that should make us want to avoid things that destroy the optimal natural internal gut-microbe balance.  And, perhaps (my opinion), we can improve things in the near-term by introducing probiotics into our gluten-free diets and avoiding anything that will further negatively impact our systems.

I like how the article concludes with forward-looking thoughts about probiotics and such:

Once researchers have a better idea of what constitutes healthy microbiota in the gut, they may be able to personalize therapies to restore that balance. It should also be possible to identify and use new types of probiotics to mitigate the impact of antibiotics, when such drugs are necessary and must be used. 

Such approaches are "an exciting target for therapeutic interventions" to treat health problems in the future, the researchers concluded.

Sounds like a good course of research to me!  And, while these people study their "bugs", I will personally continue to avoid antibiotics and antimicrobial products while at the same time enjoying my "bug-filled" (probiotics) in things like kefir, yogurt, etc.  In addition, I think my beneficial bugs much prefer a highly vegetable-laden diet :)

Gluten-Free Diet Improves Autism Symptoms

Gluten-Free Casein-Free Diet Improves Autism Symptoms in Children

Autism Researchers Examine Link to Allergies — Gluten and Casein in Particular

For those readers that are looking to a gluten-free diet in hopes of improving the symptoms of autism, new research from Penn State College of Medicine is lending some scientific basis to what many suspect: that a gluten-free and casein-free diet may lead to improvements in behavior and physiological symptoms in some children with an autism spectrum disorder (ASD).

As noted in their findings, "...autism may be more than a neurological disease -- it may involve the GI tract and the immune system." And, "Gluten and casein seem to be the most immunoreactive [allergens]", and were therefore the allergens chosen for further examination by this study.

Gluten-Free, Casein-Free, or Both: Which Diet Is Best for Autism?

Having followed this discussion for years, I have been looking forward to more in-depth scientific research on the subject. This particular Penn State study relied on information provided by 387 parents / primary-caregivers about their autistic children; a 90-item online survey on "GI symptoms, food allergy diagnoses, and suspected food sensitivities, as well as their children's degree of adherence to a gluten-free, casein-free diet"..

The study results did seem to indicate that the combination of gluten-free and casein-free works best:

"According to the researchers, some of the parents who filled out the surveys had eliminated only gluten or only casein from their children's diets, but survey results suggested that parents who completely eliminated both gluten and casein from their child's diet reported the most benefit."

The full results appeared online this month in the journal Nutritional Neuroscience.  But, i

But, I am glad the researchers also hinted at the following fact, since I consider the results a bit subjective even as they are quite valuable for spotting commonality and trends:

"While more rigorous research is needed, our findings suggest that a gluten-free, casein-free diet might be beneficial for some children on the autism spectrum," Pennesi said. "It is also possible that there are other proteins, such as soy, that are problematic for these children."

That is something to keep in mind. Although the results indicate that improvements were seen in GFCF diets, this study is not concluding that gluten and/or casein are the cause of autism or something that, if completely removed from the diet, will cure autism. Autism is a complex condition, and this is just one piece of the puzzle.  What the study definitely suggests, per the aggregate subjective feedback provided by parents of autistic children, is that a gluten-free/casein-free diet may help some children with autism improve their symptoms.

Remove Gluten and Casein to Improve Autism?

So, if you have a child with autism, should you move them to a gluten-free, casein-free diet? The researchers offered the following advice regarding this:

"If parents are going to try a gluten-free, casein-free diet with their children, they really need to stick to it in order to receive the possible benefits," she said. "It might give parents an opportunity to talk with their physicians about starting a gluten-free, casein-free diet with their children with ASD."

Antibiotics and Celiac Disease : Any Connection?

Do Antibiotics Make Celiac Disease More Likely?

Antibiotics Disrupt Gut Ecology, Metabolism

Today's Gluten-Free Blog entry was inspired as I was reading an interesting article that discussed the findings published in materials originally provided by the American Society for Microbiology, whereby researchers from Canada described many of the interactions between the intestinal microbiota and host [in their testing, the "hosts" were mice], and showed that antibiotics profoundly disrupt intestinal homeostasis (i.e., equilibrium as maintained by physiological processes). So, what happens when your intestinal equilibrium is potentially compromised by antibiotics?

Could there be a connection to gluten-intolerance and/or Celiac disease? Some portions of their findings sure made me wonder. Given how massive shifts were observed in the levels of things like hormones that affect our immune system, sugar metabolism, and more, I could not help thinking that there could be a connection with gluten-sensitivity and/or Celiac Disease.

I have also heard the term "leaky gut syndrome" thrown around by some people (though not a "recognized diagnosis", it is a hypothesis that your gut wall suffers increased permeability from exposure to toxins, infections, and medications like antibiotics). This term has been used alongside Celiac Disease and/or gluten-intolerance, autism, and chronic fatigue syndrome to name a few. Whether it is a really the cause of any of these conditions is unknown, but the theory (in relation to celiac / gluten-intolerance) is that while your intestine is in a state of increased permeability, gluten proteins (e.g., Gliadin glycoprotein) can cross into the blood where the proteins would be targeted by antibodies, and thus eventually induce an allergic/immune-response to gluten as a result of stimulating the release of cytokines (I will come back to the cytokine thing later in this blog).

Why Intestinal Microbes are Important

Normal, healthy humans each carry around several pounds of microbes in their gastro-intestinal tracts. As gross as this may sound, we need these beneficial microbes. As stated in the article (on Science Daily):

"Intestinal microbes help us digest our food, provide us with vitamins that we cannot make on our own, and protect us from microbes that make us sick, amongst other things,"

So, how profoundly do antibiotics interact with these necessary and beneficial microbes?

Antibiotics Caused Huge Changes, Including Hormone Shifts

Researchers examined over 2000 molecules present in mouse excrement before and after (administration of antibiotics to the mice) to see what changes were observable and induced by antibiotics. The "after" (antibiotics) exam showed some really amazing (perhaps scary) results where:

The second round of mass spectroscopy revealed a very different metabolic landscape. The levels of 87 percent of the molecules detected had been shifted up or down by factors ranging from 2-fold to 10,000-fold. 

The most profoundly altered pathways involved steroid hormones, eicosanoid hormones, sugar, fatty acid, and bile acid. "These hormones have very important functions in our health," says Antunes. "They [hormones observed here] control our immune system, reproductive functions, mineral balance, sugar metabolism, and many other important aspects of human metabolism."

OK, I don't know about you, but the thought of antibiotics profoundly altering various hormone levels in my body is a bit frightening. The quotation above really got my attention with regards to my interest from a gluten-intolerance / Celiac Disease standpoint, particularly  the words "control our immune system".  Given that Coeliac disease is an autoimmune disorder of the small intestine, and that the researchers observed huge shifts in the metabolic landscape that included hormones that control our immune system, one really has to start wondering if there IS a connection between Antibiotic use and Celiac Disease.

This is where I also made a mental jump back to the associated (hypothesized) "leaky-gut syndrome" and the proposed step where leaky-gut leads to the stimulated release of cytokines. Well, Cytokines are cell-signaling protein molecules secreted by the nervous and immune systems. And, more interesting may be the fact that (as Wikipedia notes): "Biochemists disagree as to which molecules should be termed cytokines and which hormones. As we learn more about each, anatomic and structural distinctions between the two are fading."    So, if cytokines are essentially a class of hormone, and antibiotics have been shown to substantially alter hormone balances, could this "leaky gut" view of Celiac Disease, Autism, and such have some merit? Hmmm... sure seems there could be some connection.

Antibiotics Can Lead to Bad Things (for Human Health)

If you have read this Gluten-Free Blog entry to this point, you are probably already thinking: "antibiotics may be causing issues for people". Well, I was sure thinking that as I read the study that inspired me to write this, and there is a nice summary-statement included in that scientific article that will confirm this line of thinking:

The findings have two important implications, says Antunes. "First, our work shows that the unnecessary use of antibiotics has deleterious effects on human health that were previously unappreciated. Also, the fact that our gut microbes control these important molecules raises the possibility that manipulating these microbes could be used to modulate diseases that have hormonal or metabolic origins (such as inmmunodeficiency, depression, diabetes and others).

The bottom-line (as I took it to be): avoid unnecessary exposure to antibiotics. Simply put, there are risks with taking them. Sure, there are some types of infections that may absolutely require treatment with antibiotics, but all too often they are over-prescribed because we (the end-user) go in to see our doctor and make a big fuss about "needing" antibiotics, or perhaps we encounter a doctor whose first line of "treatment" is antibiotics for everything (been there before!). Fact is, we need to be educated (medical) consumers and understand what antibiotics can do for us and what they can not.

Although this is just my opinion, I personally think there IS a connection between antibiotic use and Celiac Disease / Gluten-Intolerance. I developed this condition soon after being given a course of antibiotics for a supposed sinus infection (one which a week later another doctor decided I never had!), and it just makes me that much more curious as to whether there is a connection. Also, I know a LOT of people that also "developed" Celiac Disease and are now on a mandatory gluten-free diet for life, soon after a round or two of antibiotics (especially in people that normally did not take antibiotics). This is perhaps purely anecdotal evidence, but I have encountered enough such "evidence" to make me wonder. And, this scientific study just helped provide a foundation for at least a portion of my concerns.

Do you suffer "Gluten-Brain"? The neurological manifestation of Celiac Disease exposed...

If you ever needed confirmation that Gluten can lead to a lack of proper brain-functioning and/or other nervous-system disorders and symptoms thereof (without the presence of gastrointestinal manifestations as well), an article by David Perlmutter, M.D (a Board-Certified Neurologist) that I read today is sure to be enlightening.

The article discussed the case history of a 9-year old child that was previously undiagnosed (with Celiac Disease) and suffered from no particular symptoms that would make one immediately think: "Celiac!"; there was no history of the typical abdominal symptoms that doctors first associate with Celiac Disease, but rather a variable amount of cognitive impairment manifesting as difficulty thinking, memory issues, and general academic performance decline.

What caught the attention of Dr. Perlmutter was the fact that although "...she [the 9-year old patient] had no significant medical problems in her past and her overall physical, as well as neurological examinations were entirely normal...", [...] "...her problems were not constant, indicating that basically her brain was intact but something seemed to be detrimentally influencing her from time to time, causing her to have these significant issues with respect to how her brain functioned."  Dr. Perlmutter recognized the possibility that DIET was perhaps the culprit (due to the fluctuating cognitive impairment), and ran blood tests that confirmed a profound sensitivity to gluten in this girl.

Within just a couple weeks of implementing a strict gluten-free diet for this young patient, the girl experienced a remarkable change in her cognitive function (for the better), and this improvement in symptoms continued over the next several months as the gluten-free diet was maintained.  Her parents reported the following:

"Karen is completing third grade this year. Prior to removing gluten from her diet, academics, especially math, were difficult. As you can see, she is now soaring in math. Based upon this test, entering the fourth grade next year, she would be at the top of her class. The teacher indicated that if she skipped fourth grade and went to fifth grade, she would be in the middle of her class. What an accomplishment!"

WOW! Gluten was knocking this girl's brain for a loop, and once it was removed from her diet, she quickly returned to normal functioning!  This is certainly more evidence for why we need to maintain a STRICT GLUTEN-FREE DIET if we want to live life to the fullest and function normally. 

I personally can tell the difference gluten makes (with regards to my thinking process) if I am accidentally exposed to it these days, and I have other friends (with gluten sensitivity / gluten intolerance) that have repeatedly experienced "gluten brain" whereby they find it difficult to think, formulate thoughts, and even articulate themselves in a coherent fashion.  This condition is not one to be taken lightly, and we need to avoid gluten 100%.

Hopefully the medical community at large will begin to receive further education into the devastating effects of Celiac Disease -- effects that go beyond the GI tract and into our gray matter.  Like the author (Dr. Perlmuter) states:

Standard medical text books typically describe celiac disease (gluten sensitivity) as being primarily a gastrointestinal problem. I recall in medical school being taught that celiac disease was characterized by abdominal pain, abdominal distention with bloating and gas, decreased appetite, diarrhea, nausea, unexplained weight loss and growth delay in children. Newer research indicates that celiac disease can have a profound effect on the nervous system.

And, if that quote is not enough, when you start seeing the words TOXIC and BRAIN in the same sentence discussing a condition you have (Celiac), it is time to really snap to attention and take notice:

Dr. Maios Hadjivassiliou of the United Kingdom, a recognized world authority on gluten sensitivity, has reported in the journal, The Lancet, that "gluten sensitivity can be primarily and at times, exclusively a neurological disease." That is, people can manifest gluten sensitivity by having issues with brain function without any gastrointestinal problems whatsoever. Dr. Hadjivassiliou indicates that the antibodies that a person has when they are gluten sensitive can be directly and uniquely toxic to the brain.

EEK!  I do not want any brain-toxins in MY body, thank you!  This type of article may make me even more paranoid about my desire to remain free of gluten, though it seems my concern stems from substantial scientific basis.  I take quite a few precautions to keep (wheat, rye, barley) gluten out of my diet, and I will maintain vigilance with regards to this task as I go through life.   This is an allergy not to be taken lightly.

I do not want to suffer "gluten brain" ever again!  Although the article focused on the manifestation of what I call "gluten brain" (i.e., cognitive impairment) in children affected with gluten-sensitivity, the fact is this condition affects ADULTS as well.  I personally experienced severe bouts of cognitive impairment and neurological manifestations prior to discovering I had Celiac Disease.  It was a terrible period in my life, and I never want to end up like that again.  This disease nearly killed me before I knew what it was that was destroying me (i.e., gluten), and it took years for some of the symptoms to abate and/or disappear completely.  The periods of being dizzy all the time, living with parathesia (rather badly) in my feet, being unable to think clearly, and more... that is gone, along with the gluten.  Doctors I dealt with during that time of my life had, quite literally, no experience with Celiac Disease and never even considered it... luckily my brain was functioning (on "good days") enough to perform my own research discover Celiac Disease before it was too late.  It would have been nice if someone else (e.g., doctors) would have considered this prior to all those tests: MRI, CT, EKG, EEG, and a boatload of others I just assume forget.  I wonder if today those same doctors I dealt with a mere 7 or 8 years ago are now educated in spotting the neurological symptoms of Celiac Disease? They had better be... if this information is out there on the Internet for the average person to learn about, I expect medical professionals to get up to speed as well.

I hope Dr. Perlmutter's article, and additional emerging research, prevents others from ever having to go through this, or at the very least I hope it helps medical professionals (and the population at large) develop an awareness that leads to very early identification of the condition before Celiac Disease / Gluten substantially reduce the quality of life for anyone else.

Gluten-Free Equals Variety (of Flours)

We have been showing our house to prospective buyers recently, and quite often when we reach the basement portion of the house-tour, the stacks of Gluten-Free Dessert Recipe books on the large commercial-duty shelving gets attention. This leads to a quick discussion along the lines of "what gluten-free is" and so on.

One major misconception that people have about gluten-free / Celiac disease diets is that it is just "flour" (i.e., white wheat flour) that must be avoided. So, I quickly enumerate the wheat, barley, and rye, as well as any derivation thereof. Then comes a discussion along the lines of "what can you eat then?" and so on.

Yesterday, a couple of nice ladies that were really interested in the house for the kitchen (fellow cooking aficionados it seems!) commented something to the effect that I must be limited to just baking with rice flour due to the Celiac Disease, at which point I started listing a whole host of additional gluten-free grains/flours and the like that we bake with (both in our cookbook recipes, and in our day-to-day cooking and baking). After browsing through our Gluten-Free Desserts cookbook, I think they got the idea, and quickly noticed that we (gluten-free types) have all sorts of variety and can bake and consume everything from cookies to cakes to cheesecakes and pies, and so on.

After presenting a "gluten-free grains quick list" to a various people over the past couple weeks, it struck me how much more VARIETY we Celiac and gluten-free diet types have when it comes to our daily flours and grains as compared to the "normal" (i.e., wheat-eating) population. The typical American diet is rather narrowly focused around processed white flour (wheat-based), and some occasional whole-wheat flour, and some corn starch perhaps.

But, here is what we Celiac Disease and gluten-free consumers have at our disposal and use regularly (or, can use regularly if we choose) for our flours of choice:

• Rice
• Corn
• Potato
• Teff
• Sorghum
• Amaranth
• Quinoa
• Buckwheat
• Millet
• Chia Seed
  
• Various bean-flours
• Squash flours (e.g., pumpkin)
• Cinnamon, Cocoa, and other spices (that I use in large quantities like flour when desired)
  
• and many more...

In addition, it seems that we are more likely (as a group of bakers / dieters) to know about other alternatives like Agave Nectar for sweetener, and whey-protein for binders, and so on.

So, whenever I encounter the theme of "living without" (with regards to living without gluten), I can not help thinking that perhaps it is the rest of the population that is living without -- without the variety of grains, flours, and ingredients that one may otherwise never encounter or experience unless essentially "forced" (by Celiac Disease, gluten-intolerance, autism, what have you...) to try all these great alternatives to "normal" flour.

Happy variety-filled baking everyone! (and, Happy Fourth-of-July too!)

Autism and Gluten-Free Diet

There has been a long-running debate in the Autism and Neurological Disorders community about whether adherence to a gluten-free and/or casein-free and/or whey-free diet is truly helpful to Autistic children and patients. We may soon finally see some definitive proof, or disproof, of whether the wheat-free, gluten-free, milk-free diet concept is advantageous or not, thanks to a clinical study underway at the University of Texas (UT) Health Science Center at Houston, TX.

UT Houston researchers are studying diet in Autistic Children to discover whether there is a possible link between gluten and/or dairy products. This is supposedly the first double-blind clinical study to determine whether science can back the anecdotal claims of parents that posit how removal of gluten and/or dairy products from their kids' diets brings about positive change and improvement in symptoms. The study employs some investigative experts in the fields of gastroenterology, psychiatry, and behavioral sciences.

Researchers acknowledge that a lot of children with autism present with gastrointestinal problems as well, but they currently lack any definitive scientific proof that these issues are directly related to brain development and resulting autism symptoms. So, this study will, in its first phase, enroll 38 autistic children between 3 and 9 years of age and try to elucidate the impact and influence that gluten and milk proteins effect on these children - if there is any correlation. Cosomorphin (a milk peptide) and gliadomorphin (a gluten peptide) are targets of the investigation, as they are thought to perhaps be related to behavioral changes in autistic children. Another aspect of this research will look into the intestinal permeability (leaky gut) issue to see how that concept interplays with autism and gluten / casein proteins.

I find this all quite encouraging, as it will certainly help shed some light on the impact, or lack thereof, a gluten-free diet (and/or milk-free diet) for a "treatment" for autism. I tend to favor science fact over just observation, though I give credence to both, and I especially find *proper* scientific study (like this one, which is using a double-blind placebo controlled approach) useful in understanding and assessing the prospects of any treatments for any conditions.

I have had a fair amount of our gluten-free dessert recipe books sell to parents that say they are trying a gluten-free diet for their children and to (or through) medical professionals, especially allergists (wheat and/or gluten allergy treatment), dietitians, and doctors that treat autism. Just the anecdotal evidence of a fairly strong correlation between autism and celiac disease, as shared between families that have claimed successful outcomes and improvements in autism symptoms by applying a gluten-free diet, has been enough to create demand for our recipes book among this group of people.

And, though I certainly enjoy selling our books to people with autism, so their kids can enjoy great desserts while being free of gluten, I would love for there to be some scientific proof (by way of this and other double-blind scientific diet studies) to back their decision to implement a gluten-free diet for their autistic children too. I'm sure parents of kids with autism feel the same way. Well, stay tuned and hopefully the study results will be forthcoming in the next few months!
