Why does wheat cause arthritis?

Wheat causes arthritis.

Before you say "What the hell is he saying now?", let me connect the dots on how this ubiquitous dietary ingredient accelerates the path to arthritis in its many forms.

1) Wheat causes glycation--Glycation is glucose-modification of proteins in the body that occurs when blood glucose exceeds 100 mg/dl. Cartilage cells are especially susceptible to glycation. The cartilage cells you had at age 18 are the very same cartilage cells you have at age 60, since they lack the ability to reproduce and repair themselves. Proteins in cartilage are highly susceptible to glycation, which makes them stiff and brittle. Stiff, brittle cartilage loses its soft, elastic, lubricating function. Damaged cartilage cells don't regenerate nor produce more protective proteins. This allows destruction of cartilage tissue, inflammation, and, eventually, bone-on-bone arthritis.

Because wheat, even whole wheat, sends blood sugar higher than almost all other foods, from table sugar to Snickers bars, glycation occurs after each and every slice of toast, every whole wheat bagel, every pita wrap.

2) Wheat is acidifying--Humans are meant to consume a diet that is net alkaline. While hunter-gatherers who consume meat along with plentiful vegetables and fruits live a net alkaline diet (urine pH 7 to 9), modern humans who consume insufficient vegetables and too much grain (of which more than 90% is usually wheat) shift the body towards net acid (urine pH 5 to 7). Wheat is The Great Disrupter, upsetting the normal pH balance that causes loss of calcium from bones, resulting in decalcification, weakness, arthritis and osteoporotic fractures.

3) Wheat causes visceral fat--The extravagant glucose-insulin surges triggered by wheat leads to accumulation of visceral fat: wheat belly.

Visceral fat not only releases inflammatory mediators like tumor necrosis factor and various interleukins, but is also itself inflamed. The inflammatory hotbed of the wheat belly leads to inflammation of joint tissues. This is why overweight and obese wheat-consuming people have more arthritis than would be explained by the burden of excess weight: inflammation makes it worse. Conversely, weight loss leads to greater relief from arthritis pain and inflammation than would be explained by just lightening the physical load.

We need a name for this wheat effect. How about "bagel bones"?

    Perhaps I could add a fourth factor: Arthritis is more and more sen as an autoimmune disease. Wheat is one of the most prominent initiators of autoimmune diseases http://bit.ly/a9Gvjk

    Not being critical or attacking your statements.  I do believe that wheat (& other grains in general) are detrimental to health.

    But my understanding is that pH in the body is in a very small window: between 7.35 and 7.45 is what i have read.

    Kathryn

    blood pH and urine pH are quite different things, but the urine pH reflects the cost that body pay to maintain the blood ph in the range you just mentioned.

    Hi, Hans--

    Yes, indeed. Yet another path by which wheat can exert joint damage.

    I suspect that there is more to this autoimmune or inflammatory pathway than suggested by rheumatoid arthritis. Unfortunately, with negative serum markers for rheumatoid arthritis or "atypical" appearances of the joint inflammation, it is often just labeled "arthralgia" or a non-specific arthritis, treated with non-steroidal agents, then dismissed.

  • Dr. William Davis

    11/14/2010 2:25:19 PM |

    Hi, Kathryn--

    Pater's comments address your concern: Tissue and serum pH is indeed tightly regulated. But there's a price to pay to maintain normal pH when disruptive acids or bases (mostly acids) are introduced. This is reflected in urine pH, an expression of net change.

  • Stargazey

    11/14/2010 2:45:04 PM |

    So low urine pH=osteoporosis? Do we have a scientific citation for this?

    I've seen all over the internet that eating lots of meat causes low blood pH, which causes osteoporosis. Obviously, what we eat cannot influence our blood pH, or we'd be dead.

    But if low urine pH caused osteoporosis, wouldn't internists everywhere be advising patients to correct that? I see them prescribing drugs plus extra calcium plus vitamin D plus exercise, but never a word about changing the net pH of the diet. Odd.

  • Joseph

    It's nicely coincidental that you mention wheat as as a cause of low blood PH. I've just found I have low blood PH during a checkup, yes wheat is slightly acid but after doing a bit of research my thinking is that it was caused by the moderate to high protein, high fat diet I have been consuming on the recommendation of alot of paleo blogs.

    To answer Stargazey, here are 6 studies I found that support the link between protein, blood PH and bone density.

    Consumption of higher protein omnivorous diets promoted decreased bone mineral density after weight loss in overweight postmenopausal women.
    The control, nonmeat, chicken, and beef groups lost 1.5%, 7.7%, 10.4%, and 8.1% weight and 0.0%, 0.4%, 1.1%, and 1.4% bone mineral density, respectively.
    http://biomedgerontology.oxfordjournals.org/content/early/2010/07/05/gerona.glq083.abstract

    Results: After adjustment for age, sex, and energy intake and control for forearm muscularity, BMI, growth velocity, and pubertal development, we observed that long-term dietary protein intake was significantly positively associated with periosteal circumference (P < 0.01), which reflected bone modeling, and with cortical area (P < 0.001), bone mineral content (P < 0.01), and polar strength strain index (P < 0.0001), which reflected a combination of modeling and remodeling. Children with a higher dietary PRAL had significantly less cortical area (P < 0.05) and bone mineral content (P < 0.01). Long-term calcium intake had no significant effect on any bone variable.
    http://journal.shouxi.net/qikan/article.php?id=206948

    We conclude that excessive dietary protein from foods with high potential renal acid load adversely affects bone, unless buffered by the consumption of alkali-rich foods or supplements.
    http://jn.nutrition.org/cgi/content/abstract/128/6/1051

    Elderly women with a high dietary ratio of animal to vegetable protein intake have more rapid femoral neck bone loss and a greater risk of hip fracture than do those with a low ratio. This suggests that an increase in vegetable protein intake and a decrease in animal protein intake may decrease bone loss and the risk of hip fracture.
    http://www.ajcn.org/cgi/content/abstract/73/1/118

    Enduced acidosis caused the loss of calcium, sodium and potassium from the cells and bones of subjects
    http://www.ncbi.nlm.nih.gov/pmc/articles/PMC292842/?page=6

    Low dietary potassium intakes and high dietary estimates of net endogenous acid production are associated with low bone mineral density in premenopausal women and increased markers of bone resorption in postmenopausal women
    http://www.ajcn.org/cgi/content/abstract/81/4/923

    Aside from protein, Ketone bodies are also acidic and cause acidosis in diabetics "diabetic keto acidosis" and alcoholics "alcoholic ketoacidosis"

    11/14/2010 3:56:53 PM |

    I find this topic extremely interesting, especially from an athletic standpoint.

    As far as acidity, osteoporosis, and Paleo, Don from Primal Wisdom delved into this in a nice 7 part series: http://donmatesz.blogspot.com/2010/03/paleo-diet-ph-does-it-matter-part-vii.html

    Add in resistance training, though, and the whole point of diet and osteoporosis becomes almost completely moot. VitD, Ca, K, P don't hold much against skeletal bone adaptation to picking heavy stuff up.

    While I've seen evidence of increased athletic performance by the addition of exogenous pH buffers (bicarbonate), I have NOT seen evidence of (quantifiable) ergogenic improvements due to an "alkaline" diet.  While there might be some merit there (I myself follow a fairly strict Paleo diet), attempting to be more "alkaline" by decreasing meat intake would only hinder my performance.

    Back on topic:  I'll echo what other have stated already, in that the mechanism for arthritis, specifically RA, would be auto-immune mediated with wheat gluten intake.  I'm surprised Dr. Davis did not mention this.

    Eating very much carb in general makes my shoulder hurt. One of my dance teachers has said the same thing about her knees.

    FWIW, both surgical anesthetic (morphine?) and wheat make me feel lousy. I didn't have any withdrawal when I quit eating wheat.

  • Joe

    11/14/2010 5:16:54 PM |

    @Mike

    While exercise may mitigate some of the effects of Acidosis such as low bone density, stress (acidosis raises cortisol), risk of panic attacks (http://www.ncbi.nlm.nih.gov/pubmed/17713689); I've read acidosis is associated with many other diseases.

    The positive effects of bicarbonate during exercise are probably related to higher muscle protein catabolysis during acidosis which would probably continue after you stopped exercising.

    Another effect of protein is to lower serum testosterone and sex binding hormone globulin. Saturated fat raises it however (http://jap.physiology.org/cgi/content/full/82/1/49)

  • Mike

    11/14/2010 11:13:52 PM |

    @Joe,

    I have no doubts chronic acidosis has strong implications in many disease etiologies; I was just stating my experience (and opinion) on the effectiveness of an alkaline diet on athletic performance, and emphasizing resistance training for optimal bone density over dietary changes.

    On buffering:  I've personally trialed a few doses of sodium bicarb w/ short duration, highly glycolytic/lactate producing workouts, and the ergogenic (performance enhancing) effect has more to do with reduction in muscle fatigue secondary to reducing H+ ions than protein catabolysis.  I believe this is why many athletes have anecdotally adopted a "high alkaline" diet without actual quantifiable data on it.  By no means am I saying it's unhealthy (a diet high in vegetables and devoid of grains most surely IS healthy!), but it just doesn't make a difference, performance wise, like actual NaHC03 loading.

    I do agree on the effects of SFA and testosterone, though---hence my choice of whey protein and coconut milk PWO.

    Hello Dr. Davis,

    I follow your blog regularly. Keep up doing the good work.I appreciate it.
    Regarding Oseoarthritis I slightly disagree:
    Osteoarthritis is one example of “The pitiful state of medical ignorance” as Dr. Mike Eades says. Patellofemoral syndrome can be rehabilitated. Your cartilage can actually get better! 80 % of Doctors and physiotherapists don’t know this. Health care system? Don’t get me started!
    I can't give you the link because the science stuff is in German.
    But here is a good post from Mark Sisson about the topic: “OA is not your destiny”.
    http://www.marksdailyapple.com/arthritis-diet/
    Here's what I have learned from my "private research":
    Movement is great for rehab but you have to start where you are. Too little load is bad for joints and too much load is bad.  Find the “magic zone” as physiotherapist Doug Kelsey says. Joints and ligaments need time to adapt. More time than muscles.
    Interesting fact I learned from smart PTs:  cartilage works actually better under load than without. Yup! Smile

    I am not too impressed by science because I know how it works. I always told my docs that the so called “chronic deseases” are not a disease but failure of self regulation in your body. This is the basic premise of Functional Medicine. Even if they believed me they shrugged their shoulders. They were not interested because they only had drugs and surgery as tools. And if you only have a hammer as a tool every problem looks like a nail.
    But here’s the good news: The docs slowly change their mind, even in Germany. Surprise…. Prof. Dr. Henning Madry, Arthritis Research, Saarland Medical School, Germany, says: Osteoarthritis is no wear and tear but a chronic disease like asthma and diabetes. Cartilage is damaged by accidents or sports injuries but very often it is induced by internal processes which are not understood. Cartilage gets weak and finally destroyed.This has nothing to do with aging per se. Many young people have OA today and many old people have no OA says Prof. Madry.
    Hey – that’s what I said for years! But I am not an MD – only a person with a brain.

    my comment - part 2
    Why are the causes of symptoms like OA not understood? Because nobody in the medical establishment looked for them. Big Pharma has no interest in research about the causes and definitively not in prevention or healing. Healthy people who are not drug junkies? Terrible for Big Pharma!
    Dr. Ron Rosedale, MD, says: “If you are going to treat a disease you need to get to the root of the disease….But the problem is that we don’t know what the root is, or we haven’t. (…) the problem is that medicine really isn’t a science, it is a business.”
    Nothing in the human body “just wears out”. Your pancreas doesn’t ” just wear out”. Stop eating tons of crap! Your liver doesn’t “just wear out”. Your eyes don’t “just wear out” – stop misusing and poisoning them. Read optometrist Jacob Liberman, PhD., or Leo Angart on why eyes get bad, you’ll be surprised. Liberman and Angart are seniors and don’t need the glasses they had as young men. Liberman’s deconstruction of “medical idiocy” in ophtalmology is great.

    There is hope!  My middle name used to be "toast", only 1/2 kidding.  I have eaten no bread for almost 3 years and the craving for it is gone. I have had a bite here and there and can feel the "hook" trying to reset so I just don't go there.  Most of the time I no longer even think about it. It does take time and persistence (stubbornness) to reset taste buds and mental concepts.

    "Wheat causes glycation--Glycation is glucose-modification of proteins in the body that occurs when blood glucose exceeds 100 mg/dl. Cartilage cells are especially susceptible to glycation."

    Is there a citation for this claim?  I understand that there is evidence that when blood glucose levels exceed 140 mg/dl our organs can be damaged, but cartilage does not contain blood vessels, so why is it 'especially susceptible to glycation?

    To be clear, I don't eat wheat, but why single out wheat as a cause of arthritis if any food that raises blood glucose levels per the claim above would cause arthritis?

  • Daniel

    11/16/2010 4:48:44 PM |

    Dr. Davis,
    You can start by posting some links on your blog, I suppose.

    Wikipedia says this about acid/base balance: http://en.wikipedia.org/wiki/Alkaline_diet

    I think if you characterize your dietary advice in terms of getting adequate minerals, it would have more solid grounding than characterizing it in terms of ph.

    Joseph, thanks for the citations.

    It appears from this reference Acid diet (high-meat protein) effects on calcium metabolism and bone health, that a high dietary protein intake causes more absorption of calcium from food, and consequently more calcium excreted in the urine.

    From this reference Protein and calcium: antagonists or synergists?, because bone is 50% mineral and 50% protein by volume, a high-protein diet and calcium supplementation are essential for maintaining and enhancing bone status. If only one element is present in sufficient quantity, bone may actually be lost.

    As other commenters have indicated, acid-base balance has little or nothing to do with the process.

    Wheat is not the cause for Rheumatoid Arthritis but only a co-factor. It is more likely to be an infection as both doctors Wyburn-Mason and  Brown claim. As a former RA pacient who got healed using the Wyburn-Mason protocol, I tend to support the infectious nature of RA, not the autoimmune theory.

    I had joint pain in my elbows and fingers for 3 or 4 years and it was getting worse.  After researching on the internet I heard about the wheat - arthritis connection, so I though I'd give it a shot.  I've now been off wheat for four months and the joint pain is gone.  I've done "experiments" where I reintroduce wheat products for one meal and the joint pain will return for the next two days. I've also lost ten pounds and most of my wheat belly.  A no wheat diet takes some planning but well worth it.

  • Dr. William Davis

    That's pretty solid, JB.

    I call it the "on again, off again" phenomenon in which you stop wheat, the symptoms stop; resume wheat, they come back. The effect can be repeated at will.

    In my mind, that is pretty solid proof of an association.

    I have bought and read your book on wheat, and it was a great discovery for me. You see, my mother's family were Italians, and pasta, pizza, biscotti, and so on, is standard fare in Italy. So, I would never, ever have thought that my joint pain in the fingers could be linked to wheat consumption. But my mother also told me that there is a strong arthritis predisposition in the family. So, when I read your book I connected the dots.
    I have taken wheat out of my diet and the joint pain is gone (it was not a big pain, it was very subtle, I'm only 37, but I was wondering why I had it). Same as JB who left a comment above: I've done the test of eating a plate of pasta, and on the same day, a few hours later, the joint pain was back. So, I'm off the wheat, and I thank you so much for having written this great book!
