Yet another reason to avoid fructose

Have you seen the Corn Refiners Association commercial campaigns to educate the American public on the safety of fructose? If you haven't, you can view these interesting specimens on You Tube:

"Get the facts--You're in for a sweet surprise: Fructose is safe in moderation!"

Two Moms

Two lovers


Beyond the fact that fructose stimulates liver production of glycerol, which thereby increases liver VLDL production and raises blood levels of triglycerides; likely stimulates appetite; increases cholesterol levels; fructose has also been clearly implicated in increasing blood levels of uric acid.

Uric acid is the substance that, in some people, precipitates in joints and causes gout, the painful inflammatory arthritis that has been increasing in prevalence over the last four decades since the introduction of fructose in 1967. While blood levels of uric acid in the early part of the 20th century averaged 3.5 mg/dl, more recent population assessments have averaged 6.0 mg/dl or higher. (Non-human mammals who don't eat processed foods, drink fruit drinks or beer, and don't eat candy have uric acid levels of <2.0 mg/dl.)

Uric acid is looking like it may prove to be an important risk factor for coronary disease and atherosclerotic plaque. It is no news that people with higher blood levels of uric acid are more likely to experience adverse cardiovascular events like heart attack. People with features of the metabolic syndrome also have higher uric acid blood levels; the more characteristics they have, the higher the uric acid level. However, the prevailing view has been that uric acid is simply an accompaniment of these processes, but not causal.

However, more recent observations suggest that increased levels of uric acid may instead be a cause of metabolic syndrome and high blood pressure.

Increased blood levels of uric acid have been shown to:

--Increase blood pressure
--Induce kidney damage (even in the absence of uric acid kidney stones)
--Antagonize insulin responses

A diagnosis of gout is not required to experience all of the adverse phenomena associated with uric acid. (For not entirely clear reasons, some people, perhaps based on pH or other factors, are more prone to trigger crystallization of uric acid in joints, similar to the phenomena of sugar crystallization when making rock candy.)

Which brings us back to fructose, a sweetener that clearly substantially increases uric acid levels. I suppose that the mothers and lovers in the Corn Refiners' commercials are right to a degree: Our kids will survive, as will you and I, despite increases in triglycerides, enhanced diabetic tendencies, amplified appetites, and increased uric acid due to fructose in our diet. We will also likely survive despite being 100 lbs overweight, partly due to the effects of fructose.

But if long-term health is your desire for you and your family, fructose has no role whatsoever to play.

Interestingly, the obviously expensive and slick ad campaigns from the Corn Refiners' videos have triggered some helpful video counterarguments:

High-fructose corn syrup
Conspiracy for Fat America
High-fructose corn syrup truth


A full discussion of uric acid, the scientific data behind uric acid as a coronary risk factor, and the nutritional means to reduce uric acid will be the topic of a thorough discussion in an upcoming Special Report on the Track Your Plaque website.

    There was an article this week in USA Today about new research pertaining to high fructose corn syrup (independent of your uric acid argument). Check it out here: http://www.usatoday.com/news/health/2008-12-08-fructose-corn-syrup_N.htm

    This all sounds doable.  It does seem that fructose is causing such health problems that the FDA should make sure it is removed from products.  We all know that we consume too much everything, so, can't they make the stuff without the fructose?  There is so much to worry about in recent years, we might as well not eat.

    I don't deny the research posted in this post.  However, things are not as simple as they seem.

    I have done quite a lot of research on Multiple Sclerosis, and high levels of uric acid are actually implicated in LOWER levels of MS.  Uric acid actually can work as an antioxidant in the body; gout and MS are almost mutually exclusive.  You will almost never see someone who has gout having MS, and vice versa.

    In fact, increasing uric acid in MS patients has been shown to DECREASE RELAPSE RATES (see abstract below.)

    So, things are not as simple as they appear.  

    Just thought I'd post this information.

        Therapeutic value of serum uric acid levels increasing in the treatment of multiple sclerosis.
        Toncev G.

        Clinical Center Kragujevac, Center of Neurology, Kragujevac, Srbija.

        BACKGROUND/AIM: Uric acid was successfully used in both, prevention and treatment of the animal model of multiple sclerosis (MS). Recently it has been shown that inosine, a ribosylated precursor of uric acid, might be used to elevate serum uric acid levels in MS patients. The aim of this study was to evaluate the safety and efficacy of oral inosine as a single drug treatment in patients with MS. METHOD: We administered inosine orally to 32 MS patients from 2001-2004 year at doses from 1-2 g daily (given twice) depending on the pretreatment serum uric acid levels. The mean follow-up interval was 37.69+/-6.55 months. The other 32 MS patients, without any treatment except for a relapse period (matched by age, sex, duration of disease and functional disability), were used as controls. The follow-up interval of these patients was 36.39 +/- 2.68 months. The neurological disability was evaluated by the Expanded Disability Status Scale score (EDSS). RESULTS: During the observed period the treated MS patients were found to have the lower relapses rate than the non-treated MS patients (Chi-square test, p = 0.001). None of the patients have showed any adverse effect of inosine treatment. The non-treated MS patients were found to have a higher increasing in the mean EDSS score than the treated ones (two-way ANOVA-repeated measures/factor times, p = 0.025). CONCLUSION: Our results suggested that the treatment approaches based on the elevation of serum uric acid levels might prove beneficial for some MS patients

        Uric acid (UA), a product of purine metabolism, may be an antioxidant, perhaps acting as a scavenger of peroxynitrite. Patients with gout have a reduced incidence of multiple sclerosis (MS). A number of studies found that patients with MS have low serum levels of UA, although it has not been established whether this represents a primary deficit or a secondary effect. UA has also been proposed as a marker of disease activity and response to immunosuppressive or immunomodulatory treatment. We retrospectively reviewed 83 relapsing-remitting or secondary progressive MS patients (64 females and 19 males) followed in our Neurology Unit. We collected data concerning demographic variables as age and sex, and clinical variables as age of onset, clinical type, disease duration, EDSS score and total number of relapses. We considered UA levels in three different situations: during a relapse, during remission period and during remission period under immunomodulatory treatment [Interferon Beta 1a i.m. (Avonex; Biogen Idec Inc., Cambridge, MA, USA), Interferon Beta 1a s.c. (Rebif; Serono Europe Limited, London, UK), Interferon Beta 1b (Betaferon; Bayer Schering Pharma AG, Berlin, Germany) or Glatiramer Acetate (Copaxone; TEVA Neuroscience LLC, Kansas City, MO, USA)]. A Wilcoxon matched pairs test was carried out to determine differences between groups. A P-value less than 0.05 was considered statistically significant. In 33 patients, we were able to compare at least one UA value obtained during a relapse with at least one when remission without treatment. Mean serum UA levels were significantly lower when measured during a relapse (r: 0.39, P: 0.024). In 27 cases, we compared at least one remission value without treatment with at least one obtained during remission and immunomodulatory treatment. Mean serum UA levels significantly increased when determined during Interferon Beta or Glatiramer Acetate therapy (r: 0.84, P < 0.001). Although we do not know exactly whether and how UA is involved in MS pathogenesis, our data suggest that UA might reflect disease activity or treatment response in MS.

    I read that Fructose is 10 times more reactive than glucose in forming AGE - Advanced Glycogen End-products - the process thought to start CAD.

    I avoid all sugar - but wonder if the extra 5-10% might make a difference.

Wheat withdrawal

Wheat withdrawal

It happens in the hospital every so often: A clean-cut, law-abiding person is hospitalized for, say, pneumonia, kidney stones, knee surgery, etc.

Everything's fine until . . . they're running down the hospital hallway stark naked, screaming about snakes on the wall, accusing nurses of trying to kill him, all while yanking out IV's and monitor patches.

It's called alcohol withdrawal. Alcohol withdrawal can range from tremulousness and sweatiness, all the way to delirium tremens, the full-blown form that leads to disorientation, seizures, fever, even death. Withdrawal can also be associated with a number of chronically used agents, such as sedatives/sleeping pills, pain medication/opiates, among others.

How about wheat?

I wouldn't have believed it, but after witnessing this effect countless times, I am convinced there is such a phenomenon: Wheat withdrawal.

You'll recognize it in someone who previously ate bread and other wheat flour-containing products freely, then eliminates them. This is followed by extreme cravings, usually for bread, cookies, or cake; profound fatigue; shakiness; mental fogginess; blue moods. The syndrome can last for up to one week.

Then, bam! Sufferers of wheat withdrawal report mental clarity superior to their wheat-crazed days, improved energy, decreased appetite and cravings, heightened mood, and, of course, fantastic drops in weight.

Why would removal of wheat from the diet trigger a withdrawal phenomenon? I can only speculate, but I believe that at least part of this response is due to a physical conversion from a glycogen (sugar)-burning metabolism to that of a fatty acid (fat mobilizing) metabolism. People who lived in the up-and-down cycle of craving and eating wheat constantly fed the sugar furnace for years and are enzymatically impaired in fat burning; they've been growing fat stores. Eliminating wheat deprives the body of this easy source of glycogen, forcing it to mobilize fatty acids in the fatty tissues. Sluggish at first, people feel fatigue, mental fogginess, etc. Once the enzymatic capacity for fat mobilization revs up, then these feelings dissipate.

Could it also relate to the opioid sequences apparently present in wheat? I wasn't even aware of this fact until a reader of The Heart Scan Blog, Anne, left this comment:

Wheat protein contains a number of opiod peptides which can be released during digestion. Some of these are thought to affect the central and peripheral nervous systems.

When I gave up gluten, I felt much worse for a few days. This is a very common reaction in those who stop eating gluten cold turkey.


Dr. BG provides a fascinating commentary on the addictive/opioid aspect of wheat addictions in her Animal Pharm Blog.

Whatever the mechanism, I believe it is a real phenomenon. It can, at times, be so overwhelming that about 20% of people who try to eliminate wheat find they are simply unable to do it without being incapacitated. Of course, that might be a lesson in itself: If withdrawal is so profound, it hints that there must be something very peculiar going on in the first place.

    I almost missed this, coming between the Big Squeeze and the NIH petition (I signed and commented, BTW).  I'm very interested in this idea of yours, and have been musing on it since I joined TYP and first came across it.  But I've wondered why you singled out wheat from other carb-heavy grains/cereals, potatoes, etc. and if it's just that it makes up such an overwhelming percentage of the typical diet.  I have been low-carbing for several years, sometimes quite strictly and sometimes less so, but other than the difficulties of convenience and finding variety, and of changing ingrained (pun originally unintended, but I like it) habits, I had none of the "withdrawal" or cravings, or even the feelings of fatigue etc. when first starting, though I was sort of expecting and prepared to have them from reading the Dr.'s Eades.  Over the last couple of months, my husband is low-carbing with me  for the first time, and he finds it much more difficult than I, but mainly because he doesn't really like many vegetables, finding many that I love to be bitter, and the few he does like are primarily the starchy ones.  He may not choose to do this long term, as he says it works for him mostly because there is nothing to look forward to at meals, I'm assuming because he doesn't choose much variety.  He is sticking with it for now, because he has lost 15 pounds along with his lower back pain, has stopped snoring and is sleeping better,and he told me yesterday that he feels better than he has for years and years. He does still eat one slice of toast at breakfast, and I know he misses buns with hamburgers, etc., but even though by desire he would eat much more wheat, corn, potatoes, I don't think that he shows signs of cravings or withdrawal.  Do you think that wheat addiction, if it exists, can be easily separated from an overall craving for other carbs?  And if so, what percentage of people do you think are affected?  Do you think ethnicity plays any part?

    I'm a long time Atkins eater and would like to know does the gluten in eggs do the same thing as the gluten in wheat, or in other words if the problem is giving up gluten "cold turkey" if you stop eating wheat products and added eggs ( which are high in gluten ) would that take care of the problem ?

    Several times in the past year, I have gone through a two-three day "fugue state" around endurance exercise and being better about sticking to a low-carb, high-fat diet.

    I agree that my mental state on the other side is positive, alert, and with plenty of energy, but the headaches, mental fog, bad mood, and mild depression make this a very frustrating time.  It's a particularly annoying side effect of coming back from a trip, or other occasion where I have to (or choose to) relax my dietary rules for a while and then "get back on the wagon".

    I don't know that I'd choose to describe this as "wheat withdrawal".  When I had to describe it to my wife, I said it was "adaptation to a fat-burning metabolism".

    Jenny--

    These observations are purely from my anecdotal experience, though large.

    Despite their anecdotal nature, I have seen this effect over and over and I do believe that somehow, for reasons I do not fully understand, wheat is unique. While all carbohydrates generate sugar effects, wheat seems to be unique in that a proportion--20%?--develop addictive patterns from it.

    Anomyous, there is no gluten in eggs. Gluten refers to the proteins in grains. All grains have gluten but the grains involved in gluten intolerance are wheat, barley and rye.

    As someone with a lifelong carbohydrate addiction problem, I do believe that there is something deadly about wheat, especially the combination of wheat and sugar.  There is no way that I could eat ten baked potatoes or ten rice puddings.  I could easily eat 10 donuts or 10 cookies.  

    My personal theory is that it is a brain chemistry problem in susceptible people.  I base that on the fact that during the 5 years that I took phen-fen, I could eat moderate amounts of wheat with no problem.  I truly believe that the now banned "fen" part of the drug altered my brain chemistry so that wheat was not quite as intoxicating.

    Hi Dr. Davis:

    Thanks so much for your TYP book.  It was very interesting.  Have you read the book Good Calories Bad Calories by Gary Taubes.  It's an excellent book providing a review of the relevant science from the past 150 years with respect to diet and chronic disease.  He discusses carbohydrate whithdrawl in his book.

    I still don't see the connection between wheat and heart disease.  What is the mechanism?  And why is it so beneficial to avoid wheat if one is not overweight and is consuming it in the form of fresh baked bread or home-made pastas versus cookies, donuts, or breakfast cereals?

    I'm thinking the difference in our flours is significant.  Different varieties, grown for different types of cooking/baking, contain different amounts of the substances we react to.  I think our wheat has been altered over time to grow so it's easier to harvest, store and process (and to process and store once again once it gets to the bakery and stores)and is less geared toward human consumption.  I tried spelt for a while there and had much less g.i. reaction than I do with general wheat flours.

    I am so glad to see a heart doctor aware of gluten addiction. I am a gluten addiction expert having seeing its impact on my own life, my family, and now my clients. The withdrawal is real and takes place on physical, emotional, and social levels. Wheat and gluten are everywhere in our culture, so care must be taken to address the entire lifestyle to ensure folks have adequate coping mechanisms and support to stay gluten free (and dairy and sugar free in most cases. An excellent book describing the opiate qualities of the gluteomorphin in gluten and the ensuing gluten withdrawal when gluten is eliminated in the newly published "The Gluten Effect" by Drs. Rick and Vikki Petersen: http://www.healthnowmedical.com/news/show_news.html?article=book_released

    Gluten Withdrawal is SO very real. I have been gluten free for about one month now. The first week or so I felt wonderful and my intestinal symptoms had subsided. Then starting about the second week I started having what felt like wide blood sugar swings and incredible hunger. I worked at getting the good stuff in like nuts and protein and worked on not over dosing on the GF Carbs, but it has been quite difficult. I feel much more jittery and irritable that usual and it is comforting to know that this too will pass...Thank You for bringing Gluten Withdrawal out from the shadows...

    i've recently discovered a wheat allergy and stopped. within days i felt the way i used to feel 15 years ago. that is: normal! however i'm on day 8 of no wheat and i'm having anxiety attacks today (anxiety was one of my wheat-allergy symptoms). do you think it's because i'm still withdrawing? looking forward to your response.

    I gave up gluten about 14 days ago.  Felt depressed, jittery, shaky and starving!  Thought I must have some blood sugar problems.  I ended up eating four wheat cookies out of despair.  I felt very happy and not depressed after that.  Made me wonder if maybe I was having withdrawls.  Did a web search and hear I am Smile Thanks for the info.

    Anonymous you're on to something. I gave up wheat a year ago and the benefits are great including a 25 pound weight loss, more energy, motivation, etc.,etc. Eating wheat with a meal is the trigger that causes a craving later -sometimes 2-3 days later- and giving in to the craving closes the loup. In other words eating the craving meal does not trigger another craving. So, I started wheat-free eating and for two days had cravings which I simply indulged. On the third day the cravings were gone for good. No miserable withdrawl symtoms.
