Dr. Oz Positive to LCHF Against Alzheimer’s!


You have to see this to believe it.

Dr. Oz, the widely popular TV doctor in the U.S., has for a long time had a very conventional approach to dietary advice. A lot of whole grains and antioxidants and more. But lately something has happened.

Time after time in the past year he has invited guests who have a completely different view of fat (for example, in the shows on cholesterol and the problems with wheat).

Now Dr. Oz goes further than ever before. 

LCHF for the Brain?

For a new episode of the show, he invited brain doctor David Perlmutter, the man behind Grain Brain, a new book that has drawn a lot of attention.

Dr. Perlmutter recommends a strict LCHF diet to keep blood sugar down and prevent Alzheimer dementia.  This is something that hasn’t been tested yet in controlled studies, so we don’t know how effective it is. But there are lots of scientific suggestions that it may be beneficial.

For example, there are statistically strong links between high blood sugar levels and dementia and between a high-carb diet and dementia.

Dr. Perlmutter is very eloquent and Dr. Oz is completely with him, amazingly enough. He doesn’t even protest at the suggestion that butter is good for you, instead he agrees! All while the audience is cheering…

Here’s what Dr. Oz has to say, among other things, about the recommendation for an LCHF diet and butter:

Incidentally, cardiologists like myself are starting to buy into this idea, because I think you’re right. What makes us die from heart disease and stroke and Alzheimer’s is inflammation in the body and that’s not caused by fats that we’ve been eating for two and a half million years. It’s caused by new changes in our diet…

When even the American TV guru Dr. Oz begins to accept that butter is a healthful food, then the general paradigm shift is very near. And if foods higher in fat, with less sugar and rapidly digested starch, are proven to even prevent Alzheimer’s, the benefits for public health will be enormous.

Grain Brain

    HA! That weasel Dr Oz should invite Gary Taubes back on and apologize on national TV for his shi... er ... less than honorable treatment!! I'm dubious that Oz is actually changing his mind -- he seems to blow with the advertising / public dollar, not with the science... {disgusted}

    My food is more traditional due to my upbringing during socialism when we did all cooking from a scratch, and we did a lot of clothes making and fixing broken things. Even now I always have fermented food in my fridge. The taste preferences settle down during childhood, the older I get, the less I want something to eat I was not familiar with 40 years ago. Even very tasty things like carry sauces feel like the food with too intense flavor, but I can eat cabbage soup every day. From that perspective, I think it is not a good idea to feed children with a special food full of sugar and bright artificial coloring.
    If I remember properly, young ducks couldn't develop proper joints if fed with a lot of bread because the bread interfered with the absorption of nutrients, and as a result, the unfortunate birds couldn't fly. It was printed on a sigh next to a pond.

    Good points Galina.

    And I agree with advice that bread is bad for birds... it just seems odd (ironic?) that while they are arguably better adapted to digest grains than we humans are, it has been recognised, by the RSPB etc... that bread is not good for them; while our Health Establishment, marketing etc... (and eddy) still pushes those same grains on us :-)

    weight loss on a low carb diet can be attributed to protein , it is the protein that keeps one full for a longer period of time thus reduces the amount of food consumed. In the long run this diet is not sustainable for many people.

    In order to be complitely fare, it should be some difference for birds collecting whatever they may find in a wild, grains included, and sustaining mostly on a bread thrown to them by park visitors.
    We spread around our bad health with the food our civilisation produces, look at dogs, cats and even horses
    When I was little, my mom told me "eat that healthy oatmeal, horses can't run fast if not fed than wonderful grain", but it was the rare instance when mom was wrong - horses have sub-optimal health too when fed a lot of carbohydrates, oats included.

    "The term Equine Grain-Associated Disorders is used to describe both digestive and metabolic disorders in horses. The digestive disturbances involve rapid carbohydrate fermentation and insulin resistance, including some forms of colic, colitis, diarrhea, gastric ulcers and laminitis. The metabolic conditions include some forms of gastric ulcers, laminitis, exertional rhabdomyolysis (tying-up), osteochondrosis, growth rate fluctuations, flexure deformities, hyperlipidemia, oxidative stress, aging, obesity and, possibly, abortion. Some of these risk factors might be nonessential but contributing factors to the disorders.

    Dietary recommendations for horses include 1) avoiding high glycemic feeds such as “sweet feed” and oats, which produce increased blood sugar after meals and 2) avoiding unprocessed corn and high-fructan pasture grasses, which provide highly fermentable carbohydrates to the large intestine.

    Once again (and I believe I already remarked on this... Dr Andreas on this blog here is promoting LCHF and not LCHP

    And again I have been eating this way, with no need nor desire to change, for over five years. So when can I expect it to get difficult?

    Now if you really want to feel full, try snacking on a stick of butter! :-P

    Agree not sustainable. It is way too much protein which means not a LCHF diet. The LC diet used was 15% carbs, 28% protein and 57% fat, not a good choice. Less than 5% carbs, 80+% fat and 15% protein is better for the kidneys and the system.

    You never respond to our comments, you are just loading up new "ready made links", Eddy.
    This lack of discussion from your side is really the reason many here think you are just a troll,as that is the "play safe" modus operandi for trolls.
    What do you think about grains being bad for birds but ok(?) for us that have less built in skills to digest seeds? And non-fermented maize causing pellagra? Phythates in grains reducing absorption of all nutrients eaten at the same time ?
    Horses not thriving on too much oats!
    There are lots of dead threads there from your side, unless we can hear your opinions now.
    This is a discussion forum, we want to promote discussion as it often widens our perspectives and create new areas of interest for us and other open minded.

    Eddy you and your bosses do not understand the principals of Low carbohydrate High Fat diet. It is LOW CARBOHYDRATE. In the paper you cite, one tested diet had 41% energy as carbohydrates and the other 66%. LOW CARBOHYDRATE means below 10% energy. BUT, I am sure you and your bosses are not that stupid - you think that all of us here are. However if you in your genuine understanding of LCHF presented this link as a support for your way of thinking, than, well go back to the books (or pages of this blog) and do not waste our time because most of us here do read original research papers and can draw our own conclusions.

    Possible reasons for Alzheimers listed by Perlmutter in his book Grain Brain:

    * lived with chronic high blood sugar levels even in the absence of diabetes
    * eaten too many carbohydrates throughout his or her life
    * opted for a low-fat diet that minimized cholesterol
    * had undiagnosed sensitivity to gluten, the protein found in wheat, rye, and barley

    LCHF minimizes all the risks as it provides stable low blood sugar and minimum if any grains.

    Grain protein is low-quality and incomplete. It lacks essential amino acids. That diet is not sustainable for anybody. And if it's true weight loss can be attributed to protein, then we can safely say a diet that contains grains will be less effective for that purpose.

    Exactly. We can't rely on Dr Oz. Nevertheless, we can use him now that we know he's not averse to promoting LCHF. In a way, I argue for a neutral platform where all opinions are welcome, and we can argue the pros and cons freely, so that the best is allowed to rule on its own merit, if merit exists of course. The Dr Oz show fits this idea of a neutral platform to some extent. If not, then I'll just take the increased LCHF exposure thankyouverymuch.

  14. sten
    Yes, even for horses!
    Due to the strong cause-effect connection daily grains-daily high blood sugar peaks - long term dementia many grain users will never notice, although combined with lack of natural dietary fats including animal derived omega-3 can make them depressed or aggressive, unrelated. (Prozac)
  15. Galina L.
    I was surprised myself. People are not like horses, but many believe that unhealthy diet may be compensated with a healthy life-stile which includes a lot of moving and cardio. Many even think that without a lot of carbohydrates they will not be able to do their healthy exercises. I guess, humans should chill-our a little bit in their love for grains and see it for what it is - not a poison, but not suitable to be a staple food , and definitely not a good base for a food pyramid.
  16. Lisa
    Dr Oz yo-yo's with his advice and comments depending who is on the show. He has also had Dr Davis on regarding Wheat Belly, Dr Sinatra and Jonny Bowden with the cholesterol myth and Loren Cordain to name a few others.




    Yet he still goes back to pushing his "healthy" whole grains and low fat dietary advice especially saturated fat.

    He should pick a dietary approach that he believes and stand by it regardless of who supports his view. I'm sure he's a great cardiothoracic surgeon and cares about people's health but he looks like a kook with his wishy washy ever changing diet advice with the latest quick fix.

    "May all the opposition to big pharma and big food be poor and hungry as church rats and they will then be very easy to defeat."

    The income goes to finance conference trips and keep this site up to growing user demand etc., as explained several times before.
    It makes sense for me, but not for big food and big pharma or their allies, of course.

    The alternative health sites that make some income like this one and Mercola are the most successful and far reaching, so naturally they are intensely attacked.

  19. Graham_LCHF
    Dr. Oz is in showbiz not medicine, let alone science, hence he will change his opinions based on what he thinks will be popular at any given moment.

    So he's not really someone to promote - in general.

    And even a broken clock can be right twice a day.

    Given the buzz around 'Wheat Belly' and the like Oz has jumped on the bandwagon - but I doubt it's anything more than a cynical move on his part.

    As you would have known if you read all the posts above it is the fact that these two doctors, Dr William Davies in cardiology with his book "Wheat Belly", and Dr David Perlmutter in neurology with his new book "Grain Brain" were given the opportunity reach a much wider audience than sometimes nerdy LC blogs, that I think is just great!
    Here link to Dr Davies website: http://www.trackyourplaque.com/

    Usually such news are being kept well away from the general public as they can as now clash severely with advertiser interest: In these two cases the wheat and sugar based mass food industry and the ADHD-drugging pharmaceutical industry were badly attacked, which you may have missed. But us others that bought the bestselling books did not miss it !

    Low carb high fat and as little wheat as possible (breakfast cereal bye bye!) is far from a "bandwagon" today, as you seem to think. But thanks to Dr Oz these new ways of thinking are reaching out to a much larger audience which means more people read both this game-changing books!

    But Dr Oz, big pharma, big food and the tobacco industry are all mainstream and therefore by default movers that are expected to defend their gained positions with the same means they often reached them, being very very cynical. So we expect lots of cynical moves from the threatened industry to discredit and attack primarily the messenger of the bad news, Dr Oz, just like you tried in your post today: Ignore the message, hit the person.
    Sorry, we don't buy it here anyway.

    Re Dr. Oz

    I'm totally on board with the LCHF approach and I have looked at the science (I'm a PhD in evolutionary biology for what it's worth) and the science of LCHF looks very robust. I have controlled my own T2 diabetes with the the aid of LCHF.

    But please don't make this Oz character some sort of hero. In general he's a TV huckster that will promote whatever he thinks is flavour of the month.

    Next week (or whenever) this Oz character will have moved on to whatever.

    What intelligent person would actually only rely on this Oz guy and his show for serious medical advice?

    It's good that he has had a couple of LCHF people on his show recently but really I think some people are giving Oz far more credit than he deserves.

    I'm all about the science. The science of LCHF looks extremely robust. I'm not really into hero worship - certainly not of the likes of Oz (or God forbide Oprah Winfrey). Oz seems like a medical version of her. Ghastly in other words.

    Data does not require a 'personality' to be convincing.

    When it comes to the science, have you had time to read Perlmutter's book yet ?
    Well referenced and the references I checked were ok. I think it is a game changer, and no matter if Dr Oz is a turncoat, he gets people to listen and also buy the important books.
    Brain Grain focus a lot on that celiac disease is a mere tip of the iceberg of gluten intolerance, and to bring this out to a wider public is enormously important. Including that the other manifestations of gluten intolerance are all kinds of neurological disorder and that high blood sugar in itself could be a savage driver behind both Alzheimer's and dementia. This is putting the finger on the problems, at last.

    Hi Sten,

    Yes I'm all for popular treatments of the subject - "Wheat Belly", "Grain Brain" etc., but I just dislike this Oz character in general. He comes across as an insincere phoney/creep - whatever he happens to be talking about.

    But LCHF is based in some strong science so it will hopefully emerge as the old orthodoxy collapses. But it will be both a 'bottom-up' and a 'top-down' phenomenon.

    People like diabetics and those suffering from metabolic syndrome etc., will, in ever increasing numbers, try the LCHF approach for themselves (a bottom-up process). Eventually the medical establishment will not be able to ignore all their patients (that have enjoyed success with LCHF) nor will they be able to ignore forever the emerging high-level (or top-down process) of peer-reviewed scientific research that already exists and will hopefully be further investigated by the excellent NuSci project et al., on the nature of carbs and nutrition/metabolism/disease.

    In the age of the internet I think such radical change to overturn shoddy orthodoxy (fat = death) can occur very rapidly in comparison to previous ages.

    Let's hope so!

    With or without Oz.

    Graham asked:

    "What intelligent person would actually only rely on this Oz guy and his show for serious medical advice?"

    Maybe some of the tens of millions
    of intelligent people in
    the U.S. who have either no medical
    insurance or very poor medical
    coverage and cannot afford to go to
    a doctor for their medical advice.

  25. Galina L.
    It is just the fact of life - in order for a medical advice to take hold in a wide audience (I observed it in US), that advice has to be not only very simplified, but really dumbed down, and preferably presented by a person acting like a clown in a doctor's outfit. I remember reading a comment on a LC blog by a lady who decided to give a try to a LC diet after watching a segment on Dr.Oz show that for an apple-shaped body LC could a the best diet. She was convinced after Dr.Oz used a propane torch on a piece of a styrofoam, that thing started to melt, and he said something like "It is a good illustration how your fat melts at the absence of carbohydrates in a diet". Some facts of life are hard to believe.

    Of course you're right - intellectual ability, interest levels, attention spans and so on vary enormously within any population. I guess I'm entirely comfortable with most biological jargon and multivariate regression analysis, general linear models, the Weibull distribution etc., so I now tend to read bits and pieces from the primary scientific literature.

    And as for anyone in the USA without medical insurance I really do have sympathy but even in the NHS things are not always good. My present 'diabetes team' seem like over-paid and under-educated idiots to be perfectly honest. For example, the reason I could NOT have the results of my HDL levels/blood lipid panel was that no-one had bothered to order one as they didn't think it was relevant.

    Instead I had my total cholesterol number quoted at me and was told to "think about taking a statin" - as 'medical care' it virtually borders on incompetence.

    So it's a new doctor for me next week and hopefully someone that can have a semi-intelligent conversation about T2 diabetes. And order a full blood lipid panel!

    Graham, I moved around a little bit, and had a chance to experience a medical care in a former Soviet Russia, in Russia after the disintegration of the Soviet Union, in Canada with government medicine, and in US living with a medical insurance. Every arrangement has advantages and disadvantages, every single one, and there were moments and times of frustration, many things we manage in my family ourselves. The bottom line - no doctor will observe you better that yourself, and every system has to be worked on if you need the result you satisfied with. There is no perfection anywhere.
    In Russia even now doctors give you a house call if you have a high temperature, a good physical therapy equipment is available for free, and it is great to treat a running nose there or a sore throat, buy god forbid a person has a cancer there, for a pain that person would be under-medicated, and a modern treatment would be available only for whole price. It is possible to wright a book on a subject, but I stop here

    Don't forget the apoquotient. (APOB/APOA). The Inter Heart study was very clear that it was the only marker that dropped linearly with risk for heart attack!
    Over 15,000 heart attacks were check world wide and -most importantly - the study was not arranged or funded by drug companies! I guess that circumstance meant that the largest study of its kind hardly got any main stream publicity.., on the other hand.
    Otherwise the higher total cholesterol 1/ the longer you live (Framingham recent..) 2/ The lesser risk for mental disorders and 3/ lowest risk for suicide. Please do us a favor and explain for the nurse, if you get the chance!

    I visit here often, and take the general message seriously. I have changed my views on fats largely as a result of the arguments. But to label these grains and carbs as "the brain's silent killers" is going too far, not least because it conflates "all" wheat with the processed sugary carbs that are smuggled into our food. We live in an age of endless, often contradictory, food scares and see too many examples of bright, non-demented elders who've enjoyed bread and grains for a lifetime to support this extremism. I know wheat has many detractors, especially the modern strains, and I appreciate fully that overweight combined with high processed carbs is a royal route to diabetes and metabolic syndrome, but the data doesn't specify for slender low-weight portion-controlled well-exercised people with a very varied diet - including wholewheat bread. The problem is that we have so many cola-guzzling, burger-chomping layabouts with huge bellies, we are getting skewed on our facts. Genetic factors certainly play a large part in both weight (metabolism) and dementia. Proper bread is far less culpable than that Chorley-processed micro-fined, high GI, denatured cotton wool that passes for bread all too often. Beyond that, big business sugar/cola/burger junk food marketeers are society's enemy and we all know it, and they own powerful friends in government. Basically, they have lawyers. Cereal grains don't. If we took away the profit-hyping sugar and left organic wholefood grains, we could be back where our great-grandparents were. And we'd be eating lard and suet and spreading real butter on our wheaten toast and, some would argue, all the better for it.

    The ticker beat me! I would add: the Chinese are said to be a lot heavier and diabetic than hitherto, which correlates with wheat having largely displaced rice in their diet, but that's prima facie. On examination, the rural population has gone to the vast cities, where the overall meal portions are bigger, the food and lifestyle are "Western" (American mostly), with the desirability of more varied flavour, colour and presentation built in, and hard physical work has been replaced by computer-based sitting for millions. As we all know, correlation is not cause.

    Please read both books, Grain Brain and Wheat Belly. William Davies argues that today's wheat - even organic - is totally different form what it was 100 years ago. Through hybridization the ones that are "richest" or contains the easiest released sugars, or raise blood sugar quickest, dominate. Davies argues that to stop arterial plaque growth blood sugar must not be allowed to spike after meals. And to reverse plaque growth he means it is perfectly feasible by keeping blood sugars low through deselecting foods that spikes it.
    Todays hybrid organically grown wheat is simply "too rich" in this context, and according to Davies a major reason for heart disease!

    Read Grain Brain and take a Cyrex array test and you may find that parts of your brain doesn't like the gluten in the grain.
    But if your blood sugar stays below 6 one hour after you organic wholewheat cereal and you have no problems with gluten sensitivity, go for the grains!
    David Perlmutter means that Celiac Disease is a small sub group of gluten sensitivity, most of the problems relates to our nervous systems and the source is usually unknown.

    Hi Trevor, here is an extract I just copied from "Wheat Belly" that gives one small perspective of damages wheat can cause through what happened when it is withdrawn:

    "..I provided a simple handout detailing how to replace wheat-based foods with other low-glycemic whole foods to create a healthy diet. After three months, my patients returned to have more blood work done. As I had anticipated, with only rare exceptions, blood sugar (glucose) had indeed often dropped from diabetic range (126 mg/ dl or greater) to normal. Yes, diabetics became nondiabetics. That’s right: Diabetes in many cases can be cured— not simply managed— by removal of carbohydrates, especially wheat, from the diet. Many of my patients had also lost twenty, thirty, even forty pounds. But it’s what I didn’t expect that astounded me. They reported that symptoms of acid reflux disappeared and the cyclic cramping and diarrhea of irritable bowel syndrome were gone. Their energy improved, they had greater focus, sleep was deeper. Rashes disappeared, even rashes that had been present for many years. Their rheumatoid arthritis pain improved or disappeared, enabling them to cut back, even eliminate, the nasty medications used to treat it."

    Which Cyrex array test - there seem to be several on the relevant web-page.

    I managed to see a different doctor and they were happy to do an basic blood-lipid panel (including HDL) which is start. At least I can see what LCHF has done for my HDL level and the ratio with total cholesterol. And a vitamin D test too to see if I need to supplement and if so at what level.

    Sten you also mentioned the apoQ test and one for fasting insulin. Can you point me in the direction of a web site that might tell me more about those test? Often they can go by slightly different names in different nations/medical systems.

    And I googled apoQ but nothing useful came up.

    Sten, many thanks for the above. I take very seriously the reported improvement in the patients described. I go with you (I hope my posts showed this) in perceiving that both modern grains and their factory processing are far less healthy judged against the traditional species and their 'primitive' cultivation and processing. If the research is pretty conclusive about wheat-withdrawal,it may chime with the many reports of marked health improvement and weight loss associated with, e.g. juicing - in that, by a long juice fast, one is avoiding wheat and much else, like sugar! And that avoidance may be highly significant in the evaluation of that kind of partial fast; maybe more than the supposed value of the juice.
    We recycle the plants and animals we eat, as they in turn recycle the nutrients we provide via the soil. Soil is not what it was.
    While I pay attention with an open mind, I reflect this all fits into a wider pattern of loss of exercise, environmental pollution exposing us to many previously rare toxins (dioxins, phthalates, a host of solvents and residues etc) and an awareness that we have to feed this exponentially planet-strangling population. We're all part of that problem, of course.
    I would cite the many record-breaking athletes that eat wheat, and the correlation of dementia with the huge growth in octogenarians, with a hockey-stick curved increase in prevalence between 60 and the late 80s; a marked upturn occurs in the very old. Undoubtedly, dementia is largely a function of age. Do we have dementia stats for wheat eating/wheat avoiding octogenarians? Some of the models suggested for cell damage are in vitro, a problem of much conjctural dietary advice. Rational metabolic pathways are suggested, but don't always convert into 'real life' bodily significance for health.
    We agree, we all seek an optimal diet. The problem for me (I am 61) is that I have lived through decades (working in hospitals most of my working life) of vehement "research based advice" giving opposite viewpoints to that which now pertians. All agreed by lifetime researchers into diet. I recall the 'dietary fibre' mania of the 1970s; the alleged tie-in between vitamins and child intelligence, superfoods, blueberries, cranberry juice, yoghurt, honey, and so many more. My overall problem is, that the research is so often based on correlational significance in single or narrow factor alterations in diet and lifestyle behaviours. So I tend to be more influenced by, say, the overall observation of health and longevity over a long period in the Mediterranean's often poorer cultures like southern Italy and Sicily, than by n=a low number, short term partial-population single-factor studies.
    Significance in research in our synthetic 'rich' cultures is so difficult to tease out. Allowing for smoking, alcohol, exercise, gender, work type, housing, country or city, travel and relocation, mental health, exposure to toxins, insecticides/weedkillers vs. 'organic', GM foods, our own genetic inheritance, total intake of sugar, kinds of sugar (sucrose, glucose/fructose, lactose, etc) intake of fat, kinds of fat (saturated, poly, mono, hydrogenated), fibre, beverages and caffeine, whether vegetarian, vegan or omnivore; it goes on.
    We bring our many beliefs to the table, none more so than about food. Much research is sponsored, biased or of dubious quality. A lot probably should not be generalized. So, to wheat. I know we HAVE to get this right. However, we want to avoid shooting off down another Holy Grail-seeking blind alley.
    I'm an identical twin. I am far more aware than most how genes and age (and mental state) affect one's personal biochemistry and symptomatology. Even in tiny matters, one's identical twin exhibits spookily similar traits and health problems overt the decades. Yes, I am a skeptic. I give uncommon consideration to all this, but I work with Robert Koch's 'pure culture' postulates (rules) for demonstrating infectivity. They amount to: when we are eliminating a host of possible factors, correlation (however persuasive) is not to be considered causative. After all, aren't peptic ulcers due to stress? We used to think it was that simple. Once.

    Here a lnk to the INTERHEART study.

    ...The strongest risk predictor globally was the apoB/apoA1 ratio (a more reliable marker of cholesterol risk), followed by current smoking (associated with a 4- and 3-fold increased risk of MI, respectively).
    Here a graph from Swedish Kostdoktor showing risk increase with the quotient
    See the blue graph a page or so down.
    I asked my doctor to get apoB/apoA ratio and fasting insulin.
    After a week or so he could confirm that the tests could be done.

    There are a few things we know for sure.
    High blood sugars to be avoided for heart health
    By avoiding wheat the food that causes the worst blood sugar spike is avoided. ( Whole grain, yes !)
    Modern wheat is largely Amylopectin A which is the fastest starch there is....
    Of course remove sugar to eliminate most fructose....
    There are other grains containing gluten, so the CYREX array test (google Cyrex) that can be avoided.

    I love traditional food which is cooked by my grandma and my mom. The traditional food is simple to cook but good for my health. I can eat a lot of rice with fresh fish cooked well with star fruit or ginger.

    sten, thanks for those points. I want to be clear that I am an advocate of LCHF and follow its principles as much as I can now. I only posted to emphasize that I fear a repetition, regarding wheat, of a blame-based single factor approach to what is wrong with out diets. The Chinese experience certainly involves wheat - but also a plethora of other factors. The real culprits are too often the simplified media reports which too often go for sensation not science. Narrow focus on single factors can be very prone to error. Our lifestyle and diet do need a make-over, and if we major on an assault on specific grains, we may go down the same magic thinking route the cranky wheat-grass advocates do. Blaming a specific food is, I think, inviting a problematic thought process which amounts to trying to find a scapegoat, to blame and send out into the desert, for our health problems. That would be as crazy as advocating, say, wheat grass or apple cider or any of the other "cures" for bad living. I hope all of us will take what is good from the excellent and rational LCHF dietary principles.
    I hope we, also, will be wary of our inbuilt tendency to adopt magic thinking, rationalization and religious blame-apportioning in the area of food choice and, specifically, the title of the book, regarding wheat and dementia, is very problematic to me as we just don't have sufficient data to be categorical about dementia and people are desperate for a cure to that scourge. We mustn't present them with any false dawns. The title has the byline "the surprising TRUTH about..." Well, the word "truth" is a massive and potentially misleading claim, and has been used in too many now-discredited diet regimes. I am not convinced "truth" should ever be used in a truly scientific evaluation of even our best theories. That said, I do see LCHF as a very rational overall route; LCHF offers a reasonable and available way to shed weight and correct poor blood chemistry, and we can evaluate our own progress on it simply and in an ongoing way. Just wanted to to clarify - LCHF offers much that is very good. Authoritative claims to be "truth"? Not good, not the way to describe proper, hypothesis-testing science.

    Trevor H. I couldn´t agree more. This is exactly what makes "Grain Brain" a problematic book. It has nothing to with what you feel about LCHF. It´s the author´s approach that is misleading. Here is my take: http://www.docsopinion.com/2013/11/05/grain-brain-take-grain-salt/

    Axel, I read your blog piece. We concur. If grains are culpable in brain dysfunction, we need more research and fast. But, till the alleged correlations are agreed to be causative, we have only a limited theory and no consensus. I take your points about cognitive dissonance, where mental mechanisms (rationalization, projection, denial, etc) reduce thought discomfort when experience conflicts with belief. We know the Philippines' millions of Catholics will use that very mechanism in an attempt to reconcile post-typhoon carnage with the 'truth' concerning the oversight of their 'caring' creator. We'll see its effect when the Pope flies in which, I predict, will be soon. Squaring psychologically painful circles in delusional disorders is what dissonance resolution is all about, but as you imply, science has to identify it and dismiss its pernicious influence.

    I think Gary Taubes should get a nobel prize for science! AND, Dr. Oz should apologise to him for treating him the way he did. We have a Medical doctor who is also a scientist here in South Africa and HE apologised to the whole world for advocating a carbo load regimen for long distance athletes. He is now our champion proponent of LCHF and his book the Real Meal Revolution is the biggest seller in the history of this country. it has just surpassed even Harry Potter over here. I have massive TYPE IIa heterozygous familial hypcholesterolemia and I astounded my doctors. Only THEN did I tell them I'm on a high saturated fat diet. For the first time in my life my numbers came down and dramatically so. But showbiz is an awful thing - it has a mind of its own and Gary Taubes was treated miserably on the Dr. Oz show. I am looking for a cardiologist in this country who will support me and not fight my diet, but they don't exist at all! It's like they just don't read ANYTHING.

    You've got that right Sten! I have yet to meet a friendly cardiologist. Now I just go in so that they can look at my mechanics and keep my mouth shut about my diet. They WILL insist on a statin which gives me rhabdomyolises very quickly and they WILL insist on a low fat diet. So now I use them only as a body mechanic. Unfortunately MY family, who carry this disease, all need a cardiologist to check us out. But we're in and out of there very fast.

    Last Thursday (April 24th) The Dr Oz show featured Dr Peter Attia. Per Dr Oz... he was wrong about the fats in the diet...flash on screen pictures of Dr. Oz with Gary Taubes. I always record the show and fast forward through all the junk and just watch good parts. Found my self just deleting most of the recordings. But IF he is going to help push the LCHF diets.. then he just may help push other doctors into accepting the best way to fit heart disease. As a diabetic there is no way I'm changing my diet.. LCHF has given me back my health.

    I hve to say something really controversial. Dr Tim Noakes here in South Africa reckons it's not for everyone - not in a sense that everyone shouldn't be on it - I THINK he's stance is that when people don't want to be on it don't push it. You must want to do your own research and change your life. That it's not fat losing diet fad. you have to decide whether you'll be on it for life or leave it rather. Also I reckon that if everyone should go onto this diet the world would suffer for it. There just is not enough grass fed and free range animals (the good stuff for uswise) to go round if the whole world should opt for LCHFand thousands of grain growing farmers (who already have massive loans at the land bank) would flounder. One has to be totally convinved (which I am) and those loved ones you know would get some longevity out of it, are the only people I give the science to (by buying them five books). it's just my personal thinking - but there is a conundrum in my thinking. If Governments don't accept it (or the bodies controlling it) then they'll ALWAYS scoff at the diet and we will not be able to find doctors to support us (funny thing that - that medicaldom will bow down to governmental bodies) sorry I was extremely oxymoronic here - it's just pondering.

    Despite feeling much better since having switched, initially to lower carb, and then low carb high fat, I was worried that my biomarkers may have been poor. I recently had a complete lipid panel and my numbers are just about perfect...far beyond the "excellent" range. This, along with increased energy and a better mood, is all I need to support the LCHF lifestyle. It also helps me stay naturally lean with a good deal of muscle. It works for me.
