Can I see your linea alba?

2. November 2010 William Davis (19)
As more and more people are eliminating wheat from their diet and losing their "wheat bellies," i.e., the muffin top around their waists along with the visceral fat beneath, I am frequently seeing something I haven't seen in years: the linea alba.

Linea alba, or "white line," refers to the band of connective tissue running vertically from sternum to pubic area. It underlies the depression that separates the horizontal abdominal rectus muscles of the "six pack" abdomen.

It's like digging in your closet and finding something you thought you'd lost years earlier. Surprise! It's been there all along. Buried deep beneath the abdominal fat from dozens of deep-crust pizzas, whole wheat pasta, and whole grain sandwiches is this pleasing anatomical feature long lost from most peoples' anteriors.


Can you see your linea alba?

Dwarf mutant wheat

31. October 2010 William Davis (13)
Here's my 12-year old standing next to dwarf wheat grown near my house. The wheat is full-grown, harvested about 2 weeks after I took this photo.

Wheat is no longer the 4-foot tall "amber waves of grain" of the 20th century. Over 99% of all wheat grown worldwide is now the 18- to 24-inch tall dwarf. New size, new biochemistry, new effects on humans. I call it dwarf "mutant" wheat despite its lack of extra limbs or eyes because of the dramatic transformation required to breed this unique synthetic plant. 

Short-stature means less stalk, faster growing. The stockier stalk also means that the heavy seed head won't cause the plant to "buckle," as 4-foot tall wheat used to. 





The thousand-plus proteins of wheat that have been transformed to generate this dwarf mutant also changed wheat's relationship to consuming humans.

Medical education in the days of Big Pharma

30. October 2010 William Davis (43)
I received this detailed email from an unexpected source: a 3rd-year medical student.

In her email, Theresa describes her frustrations in what she is witnessing for the first time, proceeding through her training and getting exposed to the realities of medical life.

Medical training, particularly clinical training from the 3rd and 4th years of medical school, onwards through internship, residency, and fellowship training, consists largely of bullying, "pimping" (meaning rapid-fire grilling of questions at trainees), and sleep deprivation. It is an extended hazing period meant to demoralize and inculcate the trainee into following the lead of superiors. Buck the system and you're . . . out. Imagine you've just sunk $190,000 and 8 years of college into getting to your internship. You are not going to chance being thrown out on principle. So you just swallow your pride, go along with the game, and echo all the answers they want you to repeat.

While Theresa laments the sad state of modern American pharmaceutical- and procedure-obsessed medicine, she provides me with hope that some young people training to practice medicine today will carve out their own paths, not the one laid for them by the pharmaceutical industry, nor fall for the temptation of higher-paying procedural specialties like orthopedics and cardiology. I am impressed with her ability to see this so early in her career.


Dr. Davis,

I am a 3rd year medical student at ________ University. I came across
your blog today, and I'm very glad I did. I appreciate the value of your time,
so I want to be as succinct as possible while still getting across what I'm
really thinking and feeling:

From what I gathered exploring your blog for a while this afternoon, the
wellness strategies you incorporate into your practice are some of the exact
things I want to do with my future patients. Personally, I strongly believe in
staying healthy by eating right, staying active, etc. For instance, I don't eat
grains or much in the way of starches and sugars. So I love the fact that you
are helping your patients make these powerful and foundational changes in their
lives.

As I'm sure was your experience, a full appreciation of nutrition and lifestyle
as a first-line health strategy is not something that was taught to me in
medical school. I came to school with this deep conviction already in my heart
and mind, and now, on my 3rd year rotations, I am still conflicted and at a loss
as to how I'm going to be able to practice medicine the way I want to, which is
to incorporate these all-important principles into the care of my patients.

What I've come to understand about the medical field today is that the
information that exists is primarily subsidized by the pharmaceutical industry,
and dictated to medical professionals as "evidence-based" treatment guidelines
and recommendations by organizations with sincere and official sounding names
like American Heart Association and American Cancer Society. Add to that the
pressure of potential malpractice litigation and the complexities of the
insurance reimbursement game, and it seems to me like what you get is a bunch of
diagnostic and medication management algorithms that any half-trained monkey
could follow. In his sleep. Which I guess would be alright if at least they
weren't algorithms based on misguided, self-serving, profit-seeking Big Pharma,
Food Inc, insurance conglomerates, and agri-politics (I think I just made that
word up.)

A lot of well-intentioned physicians are just parroting the party
line, as their patients dutifully and gratefully chomp down their statins and
diabetes drugs and blood pressure pills. And I'm sorry, but "diabetes
education" programs with curriculum put together by drug companies? How is that
even legal? Massive corporations raking in massive profits that are dependent
on uncontrolled blood sugars telling people how to best control their blood
sugars?!

Anyway, forgive my rant. What I'm getting at is this: How can I practice
medicine, with the freedom to educate/coach/treat my patients with diet and
lifestyle changes to mitigate/reverse their chronic health conditions? Without
feeling like I automatically have to first and foremost prescribe the litany of
drugs dictated by "evidence-based" guidelines? Without excessive fear of
litigation or loss of credibility among my peers? Without having to lie through
my teeth to my patients, and tell them that eating low-fat and heart-healthy
whole grains is the best way (implication also being the only scientifically
proven way) to control their diabetes, lower their cholesterol, etc, etc, etc?

I want my patients to have the full benefit of honest nutrition and lifestyle
information, and medications and surgery as necessary. I'm afraid that there
isn't room for this kind of holistic emphasis in the medical profession today.
Are there residencies that include this kind of training or at least respect
these "unconventional" philosophies? Are there clinics or practice groups that
would allow me to practice with this emphasis, or is there a bias against docs
who do not necessarily conform to the party position? Will I have no other
option but to go it alone under the auspices of my own shingle? How do you
handle these kinds of issues in your professional life?

Sincerely,
Theresa M.


A ray of hope! Perhaps Theresa is just the first among many more medical students who refuse to submit to the brainwashing practices of the pharmaceutical industry, the same mind manipulation that has hopelessly turned most of my colleagues into their unwitting puppets.

I'll be interested in watching how Theresa's experience unfolds. I've asked her to keep us informed every so often.

The Great Low-Carb Connector

28. October 2010 William Davis (15)
The effusive Jimmy Moore of Livin' La Vida Low-Carb asked me to help get the word out about his new podcast subscription service, The Livin' La Vida Low-Carb Show Fan Club.

Jimmy has been The Great Connector for the low-carb discussion, from his ubiquitous online and social media presence, to his annual low-carb cruise. He has also broadcast first class interviews of nutritional notables like Gary Taubes, Dr. Robert Lustig, and blogger Stephan Guyenet. His Fan Club expands listener involvement in the podcast process and, potentially, greater access to his guests:

My faithful listeners have long been asking me about how they can become even more engaged in the behind-the-scenes workings of the show to get the inside scoop about what’s coming next. I’ve heard people ask specifically for access to transcripts of the most popular podcasts, a listing of the interviews I’m currently working on with the ability to ask questions of those guests, to have sneak peek of audio from not-yet-released interviews and more. My amazing podcast producer, Kevin Kennedy-Spaein, and I have been discussing how to best do this for a while in an effort to meet the demands of our biggest fans and we think we’ve got just the answer for you. Introducing The Livin’ La Vida Low-Carb Show Fan Club!

This is for all intents and purposes the quintessential destination for people who can’t get enough of this podcast that goes much deeper than discussion about the low-carb lifestyle. Yes, I speak with a lot of people who are supporters of carbohydrate-restricted diets, but I also talk with fitness gurus, people who support alternative eating plans, those who have interesting theories and beliefs regarding health and much more. Wouldn’t you love to have a chance to know who’s coming up in my schedule to be able to ask them questions BEFORE I interview them? Keep in mind that my interviews are pre-recorded and air sometimes as much as 5-6 months afterwards. Members of the “fan club” would know all about who’s coming and likely will have their question asked on the air just for signing up to be a part of this exciting new addition to “The Livin’ La Vida Low-Carb Show.”

Jimmy is the guy who is bringing this disparate and widely-spread community together. He's the guy we all know, he knows "everybody." I'm looking forward to seeing how this new project makes a more involved, personal delivery of interaction possible.

New Track Your Plaque record!

27. October 2010 William Davis (19)
The record for the largest drop in heart scan score (by percentage of starting score) has been held for around three years, with 63% reduction in score.

Well, the longstanding record was broken this week: 75% reduction in score.

At the start, Freddie has disastrous lipid values:

LDL cholesterol 263 mg/dl
HDL 26 mg/dl
Triglycerides 323 mg/dl
Total cholesterol 354 mg/dl

Lipoproteins (NMR) were worse:

LDL particle number 3360 nmol/L
Small LDL 2677 nmol/L

Heart scan score: 732

Interestingly, Freddie had virtually no vitamin D in his body, with a 25-hydroxy vitamin D level that was unmeasurable.

Freddie was miserably intolerant to statin drugs, with even the smallest dose resulting in intolerable muscle aches. That's when his doctor sent him to me.

Because I felt that the dominant abnormality in Freddie's lipids and lipoproteins was small LDL particles, representing 80% of total LDL particle number, we focused his program on correcting this parameter. Freddie's program was therefore focused elimination of wheat, cornstarch, oats, and sugars, along with an eventual vitamin D dose of 20,000 units to finally achieve a 25-hydroxy vitamin D level of 66 ng/ml. No statin drug in sight.

43 lbs of weight loss and 18 months later, a second heart scan score: 183--a 75% reduction.

While the rest of the world continues to insist that coronary calcium (heart scan) scores cannot be reduced, I am seeing records being broken. I add Freddie's experience to the rapidly growing list of people who have not just stopped coronary plaque from growing, but are seizing control and reducing it, sometimes to dramatic degrees.

The Anti-AGEing Diet

22. October 2010 William Davis (36)
Advanced Glycation End-products, AGEs, are a diverse collection of compounds that have been associated with endothelial dysfunction, cataracts, kidney disease, and atherosclerosis in both animal models and human studies. Not all involve glycation nor glucose, but the catch-all name has stuck.

There are a number of actively-held theories of aging, such as the idea that aging is the result of accumulated products of oxidative injury; a genetically pre-programmed script of declining hormones and other phenomena; genetic "mis-reading" that results in disordered gene expression, debris, and uncontrolled cell proliferation (e.g., cancer); among others.

One of the fascinating theories of aging is, cutely, the AGEing theory of aging, i.e., the accumulation of AGE debris in various tissues. Such AGEs have been recovered in lenses from the eyes, atherosclerotic plaque in arteries, kidney and liver tissue, even brain tissue of people with Alzheimer's dementia. AGEs perform no known useful physiologic function: They are relatively inert once formed (especially polymeric AGEs), they do not participate in communication, they make no contribution of significance. They simply gum up the works--debris. (AGEs are to health as the USDA food pyramid is to dietary advice: material for the junkyard.)

There are two general ways to develop AGEs:

1) Endogenous--High blood glucose (any blood sugar above 100 mg/dl) will permit glycation of the various proteins of the body. The higher the blood glucose, the more glycation will proceed. Glycation also occurs at low velocity at blood glucose levels below 100 mg/dl, though this would therefore represent the "normal," expected rate of glycation. Endogenous glycation explains why people with diabetes appear to age and develop all the phenomena of aging faster than non-diabetics (kidney disease, eye diseases, atherosclerosis, dementia, etc.). Hemoglobin A1c, HbA1c, is a readily-obtainable blood test that can show how enthusiastically you have been glycating proteins (hemoglobin, in this case) over the last 2 to 3 months.

A low-carbohydrate diet is the nutritional path that limits endogenous glycation leading to AGE formation. Restricting the most obnoxious carbohydrates, the ones that increase blood sugar the most, such as wheat, cornstarch, rice starch, potato starch, tapioca starch, and sucrose, will limit endogenous AGE formation.

2) Exogenous--AGEs (here especially is where the "AGE" label is misleading, since many other reactions besides glycation lead to such compounds) are formed with cooking at high temperatures, especially meats and animal products. Therefore, a rare steak will have far less than a well-done steak. A thoroughly baked piece of salmon will have greater AGE content than sashimi.

The forms of cooking that increase AGE content the most: roasting,deep-frying, and barbecuing. Temperatures of 350 degrees Fahrenheit and greater increase AGE formation.

Therefore, cooking foods at lower temperature (e.g., baking, sauteeing, or boiling), eating meats rare whenever possible (not chicken or pork, of course), eating raw foods whenever possible (e.g., nuts) are all strategies that limit exogenous AGE exposure. And minimize or avoid butter use, if we are to believe the data that suggest that it contains the highest exogenous AGE content of any known food.

If we connect the dots and limit exposure to both endogenous and exogenous AGEs, we will therefore not trigger this collection of debris that is likely associated with disease and aging. So following a low-AGE diet may also be an anti-aging strategy.

The New Track Your Plaque Diet, soon to be released on the Track Your Plaque website, has incorporated strategies to limit both endogenous as well as exogenous AGEs.

Butter: Just because it's low-carb doesn't mean it's good

21. October 2010 William Davis (59)
The diet I advocate in the Track Your Plaque program to gain control over the factors that lead us to coronary plaque and heart attack is a low-carbohydrate diet. We begin with elimination of wheat, cornstarch, oats, and sugars in the context of an overall carbohydrate-reduced diet. We refine the program by monitoring postprandial (after-meal) glucoses.

But not everything low-carb is good for you. Fried sausages, for instance, are exceptionally unhealthy, despite having little to no carbohydrates.

An emerging but potentially very powerful issue is that of Advanced Glycation End-products, or AGEs. There are two general varieties of AGEs: endogenous (formed within the body) and exogenous (formed in food that is consumed).

Endogenous AGEs form in the body as a result of high blood glucose, i.e., glycation. When exposed to any blood glucose level of 100 mg/dl or greater, some measure of glycation will develop due to a reaction between glucose and various proteins, e.g., proteins in the lens of the eye, forming cataracts over time.

Exogenous AGEs form in food, generally as a result of heating to high-temperature. (AGEs is really a catch-all term; there are actually a number of reactions that occur in foods, not all of them involving sugars. However, the "AGE" label is used to signify all the various related compounds. The values quoted here are from Dr. Helen Vlassara's Mt. Sinai Hospital laboratory; reference below.)

Beef cooked to high-temperature yields plentiful AGEs. One gram of roast beef, for instance, contains 306,238 units. This means that an 8-oz serving yields 13.8 million units AGEs. Compare this to a boiled egg with 573 units per gram, raw tomato with 234 units per gram.

Butter contains an impressive 264,873 units AGEs per gram, the highest content per gram in the entire list of 250 foods tested in the Mt. Sinai study. A couple pats of butter (10 g) therefore contains 2.64 million units. A stick of butter that you might add to cake batter to make a cake therefore yields 30 million units of AGEs.

So there's nothing wrong with the fat of butter. It's AGEs that appear to be responsible for the endothelial dysfunction/artery-constricting, insulin-blocking, oxidation and inflammation reactions that are triggered. Among all of our food choices, butter is among the worst from this viewpoint.

Throw in the peculiar "insulinotrophic" effect of butter, and you have potent distortion of metabolic pathways, courtesy of the butter on your lobster.

(AGE data from Goldberg 2004. In this analysis, carboxymethyllysine was the marker used for AGE content.)

Incidentally, the new Track Your Plaque diet will soon be released as chapter 9 of the new Track Your Plaque book on the website.

Einkorn now in Whole Foods

16. October 2010 William Davis (19)
I just saw this at Whole Foods: einkorn pasta.

In my einkorn bread experience (In search of wheat: We bake einkorn bread), I was spared the high blood glucose and neurologic and gastrointestinal effects of conventional whole wheat grain (dwarf Triticum aestivum). I shared the einkorn bread  with four other people with histories of acute wheat sensitivities, only one of whom experienced a mild diffuse joint reaction, the other three not experiencing any symptoms.

Anyone wishing to try einkorn can now obtain commercial pasta from Jovial, an Italy-based manufacturer. It comes in spaghetti, linguine, rigatoni, fusilli, and penne rigate shapes.

Eli Rogosa, founder of The Heritage Wheat Conservancy, tells me that, in her experience, celiac suffers seem to not experience immunologic phenomena triggered by conventional wheat.

However, we've got to be careful here. The so-called ("diploid") "A" genome of einkorn shares many of the same genes as the ("hexaploid") "ABD" genomes of modern wheat, including overlap in the sequences coding for the 50-or so different glutens and glutenins. Most of the genes that code for the glutens that cause celiac and related illnesses reside in the "D" genome that are absent in the einkorn "A" genome. However, the "A" genome still codes for glutens. So there is potential for activating celiac disease in some people. Insufficient research has been devoted to this question. It is a question of extreme importance to people with celiac and other immune-mediated conditions, since re-exposure to the wrong form of gluten can increase risk of intestinal lymphoma 77-fold, as well as risk of other gastrointestinal cancers.

So einkorn should not be viewed as a cure-all for all things wheat, but as something to consider for a carbohydrate indulgence. Yes, indeed: It is a carbohydrate, with 61 grams ("net") carbs per 4 oz (uncooked) serving.
Should anyone give it a try, please be sure to report back your experience, especially if you have a history of wheat intolerance. If you have a glucose meter, pre- and 1-hour post values are the ones to measure to gauge the blood sugar effects of consumption. Because pasta tends to cause long sustained blood sugar rises, another value at 2-4 hours might be interesting.

Noodles without the headaches

14. October 2010 William Davis (26)
If you are looking for a wheat-free noodle or pasta, shirataki noodles are worth a try.

Shirataki noodles are low-carbohydrate (less than 3 g per 8 oz package) and, of course, do not trigger all the unhealthy effects of wheat--no blood sugar/insulin provocation, no addictive brain effects (exorphins), no gluten-mediated inflammatory effects.

(I advise avoiding gluten-free pasta alternatives made with rice flour and other common gluten alternatives, since they trigger blood sugar, small LDL, and growth of visceral fat just like wheat.)

I made a stir-fry using the shirataki-tofu noodles, shown below. (Tofu is added to make the noodles more noodly in consistency, as opposed to the chewier non-tofu variety.) The noodles were a lot like the ramen I used to eat as a kid. They were filling and tasted great in the sesame oil, soy sauce, tofu, and vegetables I used.


The noodles are easy to use. Just drain liquid out of package. (The noodles come in water.) Rinse in collander 30 seconds, then boil for 3 minutes. Add to your stir-fry or other dish. Some manufacturers, such as House Foods, also have angel hair and fettucine style noodles.

You're fried

13. October 2010 William Davis (26)
If I could invent a food that illustrates nearly all of the shortcomings of the American diet, it would be French fries, the familiar fixture of fast food.

What we have come to view as French fries contain just about every one of the unhealthy ingredients that lead us down the path of obesity, diabetes, heart disease, high blood pressure, etc.

Let's take them one by one:

Potato starch--Potato starch exerts an effect on blood sugar similar to that of table sugar, only worse. (Glycemic index french fries 75; glycemic index sucrose 65.)

Advanced Glycation End-products (AGEs)--AGEs form when proteins and fats are subjected to high temperature cooking; the longer the high temperature, the more the food reaction creating AGEs proceeds. AGEs are the likely culprit in roasted and fried foods that made it appear that saturated fats were bad, when it was really AGEs all along. AGEs have been shown to block insulin's effects, increase blood sugar, cause endothelial dysfunction and high blood pressure.

Acrylamides--Acrylamides, like AGEs, are created through high-temperature heating. French fries are unusually rich in AGEs. Brewed coffee also contains a small quantity, while French fries contain 82-fold greater quantities, among the highest of all known sources of acrylamides.

Oxidized oils--The amount of oxidized oils will depend on what sort of oil was used for frying. As more restaurants are trying to get away from hydrogenated oils, many are turning back to polyunsaturates. Others are turning to commercial-grade oils that contain both hydrogenated and polyunsaturates. If oils are permitted to oxidize, then they will trigger oxidative phenomena in your body upon consumptions, e.g., LDL oxidation (Staprans 1994).

In other words, the innocent appearing French fry unavoidably triggers oxidation, all the phenomena triggered by high blood glucose (high insulin, glycation, visceral fat accumulation), along with the cascade of effects arising from AGEs and acrylamides.

Top your French fries with some ketchup made with high-fructose corn syrup that exagerrates AGE formation, visceral fat, and distorts postprandial (after-eating) effects.

Is it any wonder that we've lost control over diet?

    Dr.Davis,

    Just listened to the podcast, that's fantastic !

    I have been diagnosed with TD2 last Sept, and since then being on the very low carb. Everything went well except my total cholesterol went out of control, and in January it was 400.

    What I don't understand is my Lp(a) is close to 0 ( less than 5.0 mg/dL as it was reported).

    Here is my latest direct measurements from SPECTRACELL LAB in Huston.

    VLDL Particels: 122 nmol/L (needs to be < 85)
    Total LDL Particles : 1271 nmol/L (needs to be < 900)
    Non-HDL Particles: 1394 nmol/L (needs to be < 1000)
    RLP(Remnant Lipoprotein) 205 nmol/L (needs to be < 150)
    Small Dense LDL III: 552 nmol/L (needs to be < 300, marked as very high risk right now)
    Small Dense LDL IV: 96 nmol/L (needs to be  7000)
    Large Buoyant HDL 2b: 2045 nmol/L (needs to be > 1500)

    Apo B-100: 127 mg/dL (needs to be < 80)
    Lp(a) : less than 5 mg/dL (needs to be < 30)
    C-Reactive Protein-hs : 0.2 mg/L (needs to be < 1)
    Insulin: less than 4.0 uIU/mL (needs to be < 35)
    Homocycteine: 12.3 umol/L (needs to be < 11)

    Total Cholesterol: 259 mg/dL
    LDL: 159 mg/dL
    HDL: 59 mg/dL
    Triglycerides: 118 mg/dL
    Non-HDL-Chol : 200 mg/dL


    I already removed the cheese and eggs from the diet, I suspect I am APOE 4.

    Any comments on my pattern ?

    thanks!

    To DCMarc  (server blocked where belongs),
    Benfotiamine, a synthetic thiamine used in diabetic neuropathy, increases enzyme trans-keto-lase inside a cell. The use in diabetics and neuro-degeneration may (?) require professional consideration in cancer cases. Trans-keto-lase spurs cells to go into aerobic glycolysis (aerobic here refers to cell performing glycolysis despite oxygen being around for performing normal mitochondrial oxidative phosphorylation) for processing cells glucose; this aerobic glycolysis is the  famous Warburg effect and experimentally administering trans-keto-lase augments cancer cell proliferation (likewise experimentally spiking up thiamin increases trans-keto-lase).

    Trans-keto-lase works for diabetics & in neuro-degeneration because  it pushes cell's glucose (via transcription once cAMP binds to it)  into the hexose mono-phosphate shunt ( of D-glucose-6p to D-glucono-lactone 6P to D-glycr-aldhehyde-3-phosphate) called the Pentose  Pathway (where hexose forms into pentose). This  process generates NADPH which boosts anti-oxidant glutathione ( & thioredoxin) production inside the cell. Also NADPH brings on the  activation of  the cell's endoplasmic reticulum's Unfolded Protein Response which helps the endoplasmic reticulum (ER) tolerate dangerous endoplasmic reticulum stress (ER stress is significant in diabetes and neuro-degeneration).

    ER stress, with protein folding complications, sees NADP+ accumulate and so augmenting trans-keto-lase pushes quicker output of NADPH to keep pace; this  triggers the Unfolded Protein Response to induce Cu,ZnSOD expression that then alleviates the ER stress (ie: helps ER tolerate demanding conditions).  This helps in that it  keeps the stressed ER  ( a state that coincides with more local super-oxide O--),  from seeding the dangerous (and largely un-neutralizable) hydroxyl radicals (hydroxyl radicals come about when super-oxide related hydrogen peroxide  provokes Fenton  & Haber/Weiss reactions reducing Cu++ or Fe+++ ). This is similarly how trans-keto-lase also benefits cancer cells ( rampant cancer cell growth demands protein folding that formally stresses the ER); the prevention against reactive oxygen species means cancer cells don't suffer apoptosis (cell death).

    Diabetics use of Befotiamine ( a dynamic fat soluble thiamine trans-keto-lase booster) will  help them similarly with their ER stress . In  their case the shift to using their regularly high glucose in the Pentose Pathway will mean quicker degradation of that glucose than if cells used mitochondrial oxidative phosphorylation. This also means the glycation (Doc warns against this from high glucose)  and thus tissue cells levels of advanced glycation end products (AGE) will be less; blunting the amount of AGE messing with monocytes and less endothelial dysfunction  amount to less inflammation, less diabetic oxidative stress and likewise less alteration of the vascular tissue such as atherosclerosis.

    Experimentally induced diabetes is often done by feeding a very high  fat diet. Much of the fat in a very high fat diet  acts to drive down the level of trans-keto-lase due to a transcription adaptationum within 8 weeks in rodents. For humans thiamine (B1) is often recommended to diabetics; cauliflower is a nice thiamine source to make into trans-keto-lase.

    To  B. Smith (Server won't post where belongs ),
    Glutamine, an amino acid, is used by cancer cells to keep apoptosis (cell death) from happening in several ways. One way is how glutamine keeps the cell nucleus from condensing and stops the capsase 3 & capsase 8 cascades from starting apoptosis. The other way is how there is an increase in the  anti-oxidant glutathione synthesis when glutamine elevates NADPH (see comment above for ER stress).

    Tumor Necrosis Factor alpha (TNF) works to destroy a cancer cell by running down that cell's mitochondrial glutathione level; this needs to be replenished with glutathione from that cell's cytosol. Once there is a 35% plunge in mitochondrial glutathione that  alters the mitochondrial membrane so that it stops bringing in glutathione to the mitochondria and starts leaking out cytochrome c into that cell's cytosol (which can jump start an apoptosis program). Cancer cells' rapid growth strains the normal oxidative stress limits of a cell, so cancer cells draw in lots of glutamine to boost the level of ready glutathione inside that cell; then the cytosol can continually shore up the mitochondrial glutathione levels to prevent one of the apoptosis scenarios from starting .

    A cancer cell at some point has to "transform" to progress and needs lots of DNA at that stage; glutamine is needed for synthesis of cellular RNA & DNA. The bio-synthesis of nucleotides utilizes glutamine; and having lots of de-oxy-ribo-nucleotides around favors DNA replication at that cancer's key "transformation" stage (ie: S-phase). The use of glutamine by a cancer cell for converting into energy to run on, like some normal cells do, is not why cancer cells take up so much glutamine.

    Hi GalinaL,
    Cancer undergoes several oncongenic processes wherein the so-called epithelilial pheno-type cell (epithelial cells are +/-85% of cancer substrate cells) gets it's cell nucleus histones acetylated, which creates what is called "stemness"  (the ability of that cell to renew itself with potency, like our stem cells). This leads to a phase called epithelial-mesenchymal transition (where the morphing cell can go either way, either back to benign epithelial pheno-type or onward to dangerous mesenchymal pheno-type). It is when the enzyme histone acetyl-transferase no longer keeps that epithelial histone acetylated ( a sort of  limbo) that the epithelial cell's genetic expression gets knocked down permitting the further shift into full mesenchymal pheno-type .

    What is important to realize about cancer cell's taking over a cell's nuclear DNA is that when the pheno-type goes from epithelial to mesenchymal the cancer cell's mesenchymal pheno-type somehow still retains the ability to perform the stem cell "stemness" of indefinite replication. Your cited authors point out that keotones boost tumor growth (+/-2.5 times) and lactate boosts tumor metastasis (+/- 10 times); and  also that their metabolic use raises a cell's Acetyl-CoA and this increases the acetylation of histones causing more gene expressio. And so authors report limiting ketones and lactate in cancer seem to be the "achilles heel" to cut off in order to stop cancer's "stemness" (ie: inherent potential); their extrapolation from this is interesting as a theory..

    There are other processes beyond histone modification which show oncongenesis is not lineal. When the cancer cell is still just an epithelial pheno-type cell unit micro RNA (miRNA) of the miRNA-200 family group is un-methylated; and thus holds the epithelial pheno-type steady, because un-methylated miRNA isn't reactive enough for messenger RNA (mRNA) transcription. A 2nd stage is seen once hyper-methylation  occurs, while at the same time less miRNA is put out; this morphs the cancer cell into the mesenchymal pheno-type and at that stage metastasis is possible. While an advanced 3rd stage comes about when miRNA resurges somewhat; this is what makes extensive metastasis of cancer cells that have migrated start happening. (Lineal thinking about cancer is a trap, since it is methylation that lets cancer cells get going but later de-methylation that let's them thrive and patient outcome worsen).

    Warburg effect is suggested, by cited study, to be almost a lineal concept; which they propose to re-define as desireable if it simply limits lactate and ketone production in a cell. This theory has it's own trap because in the Warburg effect +/-60% of the carbon from glucose undergoing aerobic glycolysis in cancer cells is actually being used by cancer cells as a carbon scaffolding for "de novo" fatty acid synthesis to feed into fatty acid oxidation. In other words the elevated amount of cancer cell's aerobic glycolysis (Warburg effect) is really fostering fatty acid oxidation; and fatty acid oxidation increases cancer resistance.

    The cancer cells uncouple the mitochondria oxidative phosphorylation of glucose so that the a lot of the processing of glucose doesn't go all the way to normal completion of ATP production; instead cancer cells use the initial steps that perform oxidation of glucose to cleave off the carbon atoms from that glucose to use. In other words it is the mitochondrial uncoupling protein up-regulated by that cancer cell's genetic  transcription which, down the line, forces that cell to continue to escalate Warburg's aerobic glycolysis in order to keep up with energy demands as carbon skeletons get used up.

    Metaformin's use in cancer treatment was suggested by study's authors to support their "reverse Warburg" theory : that it is by forcing Warburg's aerobic glycolysis to occur, due to Metaformin,  which accounts for cancer control seen. This seems too lineal an interpretation of the events; especially with regard to preceding paragraph's explanation of how Warburg relates to unpredictable carbon molecule usage. Metaformin reliably does inhibit the mitochondrial complex 1; and this will stymie glucose (and also glutamate, which cancer cells prodigiously take in ) from going on to produce ATP. I would suggest that this also stops the oxidizing of glucose molecules and thus sparse carbon skeletons are available to make into fatty acids for burning.

    In addition Metaformin inhibiting mitochondrial complex 1 will also reduce fatty acid oxidation; this is because  NADH oxidation at that complex needs to happen in fatty acid oxidation. NAD+ is a crucial rate limiter in  fatty acid oxidation , but unless NADH can subsequently be re-oxidized as a molecule in the mitochondrial complex 1 it can't keep on driving fatty acid oxidation by lending out NAD+.  Metaformin use in cancer is even more complicated, because if the cancer has p53 then when glucose supply is low it manages to actually use more fatty acids to run on and then use auto-phagy house cleaning to avoid apoptosis death. Whereas, if a cancer does not have much p53 then Metaformin seems to be more effective in treating cancer.

    Yup, and the nutritionist hawks the usual "cut your fat, eat more whole grains" line.

    It's a comedy of misinformation with advice from agencies paid for by your tax dollars.

    Hi, otter--

    Obviously, I can provide only limited advice in a blog post.

    But I agree: Apo E4 is a prime consideration. However, keep in mind that small LDL remains the most atherogenic (plaque-causing) of all your patterns and still deserves the primary focus. Also, if this blood sample was drawn with ongoing weight loss, this alone can provide substantial distortions.

    Wow! I don't know who else would dissect that article like you did! I really, really appreciate you decision to replay on my question. Looks like  Metaformin could be healthful in more than one way in treating cancer.
