    Ok, listen up

    LDL needs to be pattern A, fluffy, billowy kind. Individuals with triglycerides smaller/lower than 70 do NOT have small, dense LDL.

    Between 70-140 TG individuals need a test to differ fluffy pattern A from dense pattern B.

    Statins do NOT work on LDL particle size.

    Also HDL comes in different particle sizes, not all HDL is good. Some are risky, the particle size needs to be fluffy, not dense. An HDL reading of 80 with mostly small dense particle sizes is a disaster (in the process of being fixed)...

    So calling HDL 'good' is misleading.

    LDL fight bacterial, viral, fungal and parasitic infections. High LDL could mean you ate bacteria (food poisoning) and your body is fighting it off temporarily.

    Low LDL is associated with frequent infections such as a flu. You don't want your fluffy LDL low. You want high fluffy LDL, which of course will give you a higher number.

    LDL with oxidized particle = BAD.
    high LDL with healthy particle = GOOD.
    (The Cholesterol Myth)

    Low cholesterol readings is associated with high risk of cancer and early death.
    LDL binds and inactivates dangerous bacterial toxins and has beneficial influence on the immune system.

    LDL reading (mostly fluffy) above 160mg/l gives you a high immunity to infections like the flu.

    To determine true inflammation get a CRP test done.

    HDL is the shuttle that comes back with either small, dense or fluffy, healthy LDL. HDL = LDL on its way back. When LDL is low and HDL is high, most likely someone has currently NO infection and HDL is high because the person had plague build up in the arteries and it's being broken down and recycled.

    High HDL doesn't mean you are healthy, it just means you're breaking down plague. Which is good, but shouldn't be there in the first place, right?

    And, remember, particle size is what matters, nothing else! Not the total number of anything.

    Also if your digestion improved, that's because on PB the liver produces healthy amounts of cholesterol that's made into bile to digest fats!
    Without bile we would not be able to digest and absorb fats and fat-soluble vitamins like A,D,E and K. It is important for bone health! Retinol, vitamin D3, transforming minerals into bio-available minerals, e.g. rock minerals getting chelated through bile.

    High LDL builds new cells, repairs and delivers nutrients.

    Also, in winter cholesterol goes up, in summer cholesterol goes down. Cholesterol readings are different every day, at different times, each minute!

    Blood cholesterol goes up during dental treatment.
    LDL is a shuttle of cholesterol to the 'wound'.

    Accurate tests for detailed analysis of actual lipoproteins particle size:

    Liquid Chromatography, Gel Electropheresis, density gradient Centrifugation or NMR= Nuclear Magnetic Resonance.

    smaller HDL particles are less desirable and are actually risky
    smaller HDL particles are less protective (if at all)
    smaller LDL particles are big contributors to plague.

      Consider that at 251 and a KNOWN variance of up to 30 points from one day to the next you could very well be in the 200-240 range which has the lowest rate of overall mortality. That doesn't seem all that bad to me. Cholesterol is much like BP. You need to average multiple tests to get a valid number.

      Oh, and one other thing.....the accuracy of these tests like NMR for particle size are quite suspect at this time. So much so that (think 30-50%) that they may be fairly worthless from what I understand. Check out Chris Kressler for more on this.

    Animal Pharm: Ancient Transporters: HDL and LDL Lipoproteins Carry Precious Cargo

    Animal Pharm: Ancient Transporters: HDL and LDL Lipoproteins Carry Precious Cargo

    The NCEP/ATP III Cholesterol Guidelines Bogus: 'Cholesterol Limits Lose Their Lustre'

    Conventional medicine at this time uses Big Pharma-funded assessment and treatment guidelines which promote the use of statins as first line in order to 'treat' the LDL (goal less than 70, 100, or 130 mg/dl) to targets based on risk stratification, e.g. age, prior family history coronary events, low HDL, smoking and presence of hypertension.

    What are the true root causes of these 'risk factors' in light of evolution (if you believe in evo)? Is LDL really 'bad'?

    Indeed.

    Hormonal havoc and energy balance dysregulation caused by neolithic excess of refined n-6 vegetable oils, high fructose GMO-corn syrup, intestinal permeability, refined carbohydrates, sugar, mercury/arsenic/lead/cadmium, gut dysbiosis, failures of vitamin/mineral absorption by the action of phytates and lectins, and endocrine-disrupting consequences of pesticides and other environmental persistent-organic toxins are more likely factors.

    And they have nothing to do with LDL. Half of heart attacks occur in individuals where the LDL is already less than 70 mg/dl.

    The old cholesterol guidelines NCEP/ATP-III  that were first put out over a decade ago are now being revamped.  Nature has a new article on the future NCEP/ATP-IV.


    'Since 2002, when ATP III called on doctors to push LDL levels below set targets, the concept of low cholesterol has become synonymous with heart health. Patients brag about their cholesterol scores, physicians joke about adding statins to drinking water, and some hospitals reward doctors when patients hit cholesterol targets.'

    LDL Affected by Apo E Alleles




    Amount of LDL-C and LDL-P Determined by ApoE

    We each individually and uniquely have widely varied lipoprotein patterns (LDL, TG, HDL) determined by our genetics, the microniche our ancestors evolved and survived in, and our apolipoprotein E. Apo E is mainly found in HDL and LDL particles but also free form in the circulation as well. It aids lipoprotein particles in docking up to cell membranes to unload contents into a destination cell or the liver.

    Apo E determines the LDL-quantity. Three alleles for apoE exist and we each have 2 copies from a mix from our parents - E2, E3 or E4. ApoE to me is like a special key to unlock troubled doors. Those with E4 alleles have lipoproteins with the least apoE (perhaps true H-G, more cholesterol hung out longer in circulation). 

    Geographically the incidence of E4 rises toward a northern distribution in Europe, away from the equator.   

    Those with E2, more apoE (perhaps more agarian adapted).  Energy flux patterns and metabolism are mildly different: E4, more carbohydrate sensitive; E2, less.  

    Many 'cardiac' rat models use apoE-deficient mice because these animals inevitably develop horrific plaque and atherosclerotic disease and blocked arteries, on high carb rat chow.

    The lower the apo E alleles, the lower the total cholesterol [ref 2]. The researchers (above) demonstrate the LDL and HDL trend in parallel with total cholesterol and the higher the E.  Conversely, triglycerides grow higher, the lower the apo E.

    It seems finally that the medical community be viewing the true science and questioning the BS.  If LDL is genetically determined by the apoE type and is a false coronary risk factor, then what is the true cause of coronary events, MIs, angina and plaque destabilization? 

    Naturally if one is apoE 4/4 (rare), then one is likely to have the highest LDL amongst friends and aquaintances. Is it harmful? Depends. ApoE 4/4 are more likely to be HIGHLY insulin resistant, inflamed and carbohydrate sensitive. In the modern industrial environment where whole food, ancestrally-inclined meals are endangered species... perhaps.  

    Are apoE 4/4 the true survivors of Earth? They are less likely to suffer from infections or starvation which were the major reasons for mortality outside of predation prior to neolithic times. Add to that vascular protection from Lp(a) from vitamin C-deficiency hemolysis and one has a winning combination for longevity given the right circumstances when inflammation is well regulated and gene-protein expression optimal. 

    The higher the LDL, the higher the Lp(a), the better survival?



    Size of LDL Determined by Diet and Lifestyles: Microecological Niche

    Environment dictates the LDL-particle-size. Exercise, high saturated fat, cholesterol-intake, low carb, low fructose, low omega-6/omega-3 ratio and antioxidants/flavonoids are factors that high influence and create more large, buoyant, resistant-to-oxidation LDL-particle-sizes, despite apoE status.



    LDL Less Than 70 mg/dL is Dangerous

    So why are cardiac 'experts' prescribing a one-size-fits-all LDL goal of less than 70 mg/dl and statins for all individuals with heart disease, diabetes, aneurysms, chronic kidney disease, and other atherosclerotic equivalents?

    Does this take into account apoE status and genetically-predetermined LDL amounts?

    An LDL less than 70 mg/dl is not magic.  At TYP, very rarely did I observe CAC Agatson coronary artery calcification reversal.  Members were on potent statins or suppressed their LDL to (unnatural) goals of 60 mg/dl. 

    Seth Roberts did achieve reversal, by consuming cholesterol (butter). No pharmaceuticals.

    I have noticed countless, sad times where statins do nothing to regress or stop the progression plaque. In fact, they are associated with progression in 12 out 14 published coronary calcification studies.

    Many studies show that statins are also highly associated with cancer, increased incidence of congestive heart failure (CHF), accidents, violent death, depression/suicide, and all-cause mortality.

    Low cholesterol and low LDL, independently, additionally are significantly correlated to cancer, increased incidence of chronic heart failure and all-cause mortality.

    Let's probe this... because statins lost their allure years ago for me.




    Overview of Transporters

    Every vital vitamin, hormone and steroid exists both 'free' and available in the blood circulatory system and bound to degrees to a transporter-protein. Some vitamins, hormones and steroids interact directly with receptors on cell membranes and other cases the transporter-protein interacts with receptors on cell membranes to translocate the vitamin, hormone or steroid into the cell. From the gut to the liver, food gets processed into free fatty acids, triglycerides (3 fatty acids attached to one sugar backbone) and bundled into particles with antioxidants for circulation and storage in peripheral tissues like the muscles, adipose, gonads, and adrenals.



    Cholesterol

    Every cell membrane is composed of cholesterol -- this is the asphalt and infracture of our communication highways. Another way to appreciate these conductors of electronic charge is to recognize that cholesterol in our cellular membranes is analogous to the DSL or Comcast cables of our high-speed computers, our brain and nervous systems.

    How do 'dropped signals' feel? Perhaps your cholesterol is impaired?

    Roles of cholesterol:
    a) formation of cellular walls
    b) formation of aldosterone (important for blood pressure regulation)
    c) formation of the sex hormones
    d) formation of Vitamin D
    e) formation of bile to eliminate and recycle wasted and precious fat-soluble molecules
    f)  formation of corticosteroids which are involved with glucose regulation and suppressing inflammation

    g) formation of steroidal derivatives including the vital and potent antioxidant Ubiquinol/ CoenzymeQ10
    h) antioxidant with scavenger functions for harmful microbial endotoxins


    Without cholesterol, humans cannot survive, brain and organ function deteriorate, and eventually cancer and other inflammatory conditions are triggered. Without sufficient cholesterol, cortisol, testosterone, progesterone, estrogens and other potent steroidal hormones cannot be made.



    Statins Lower Testosterone

    As one would expect, statin pharmaceuticals which block the rate-limiting enzyme for cholesterol production in the liver and all extrahepatic sites (e.g. BRAIN, ADRENALS, TESTICLES, etc), HMG-CoA reductase, are highly associated in reduction of total testosterone and subsequent low testosterone signs and symptoms [ref 3-9].

    Low testosterone is also considered a risk factor for heart disease due to the inflammatory state that occurs including obesity, metabolic syndrome, hyperinsulinemia, poor immunity and diabetes[ref 7]. I question the prudence in the strategy behind initiating a statin and potentially lowering testosterone further, thereby inducing yet another cardiac risk factor.  Would you like to be a eunuch?

    Ancient Transporters

    Our lymphatics and blood vessels form the highways that transport nutrition, oxygen and necessary constituents for organ maintenance and rebuilding. They also remove wastes, CO2 and recycled cellular parts and spent steroid hormones for elimination via the gut or 'recycling' via enterohepatic recirculation.

    How are antioxidants, pro-vitamins, vitamins, pro-hormones and hormones from our food and endocrine glands/tissues carried to the peripheral sites? Ancient tranports have evolved (if you believe in evolution) in all living systems for the role of carrying these items to the appropriate target tissues.

    Vitamin A (retinol): free and bound to RBP (retinol-binding protein)
    Vitamin D (cholecalciferol): free and bound to VDBP (vitamin D binding protein, aka Gc globulin)
    Estrogen (E1 E2 E3): free and bound to SHBG (sex-hormone binding globulin) and EBP (estrogen-binding protein)
    Testosterone, DHT: free and bound to SHBG and ABP (androgen-binding protein)
    Progesterone: free and bound to SHBG and PBP (progesterone-binding protein)
    DHEA: free and bound in HDL particles
    Cortisol: free and bound to CBP (cortisol binding protein)

    Ubiquinol/CoQ10:  bound in HDL and LDL
    Menaquinones (MK4 to 9; vitamin K2):  bound in HDL and LDL
    Retinoids (vitamin A):  bound in HDL and LDL
    Carotenoids (vitamin A): bound in HDL and LDL
    Tocopherols, tocotrienols (vitamin E): bound in HDL and LDL
    Minerals - iodine zinc selenium copper: Free form and bound in HDL and LDL
    Cholesterol: Free form and bound as Esters in HDL and LDL


    See prior animal pharm: LDL, HDL Transporters



    Purpose of LDL and HDL Transporters: Evo Perspective

    Lipid transport and delivery systems existed in the earliest animals including insects. Our lipoprotein systems are not that dissimilar [ref 1]. Fat-soluble nutrients like cholesterol, carotenoids, vitamin E and coenzyme Q10 would form a two-layered oil-vinegar like concoction in our blood circulatory system if it were not for specialized transporters for fat-like substances.

    HDLs are much more compact and smaller in size than LDL. They fit between the gap and communication junctions in the endothelium (lining of blood vessels). Whereas, LDL particles are larger and barely fit between normal gap junctions of endothelium. If the LDL particles however are 'small' their purpose is different. They are more oxidizable and denser. This tighter conformation allows movement into damaged endothelium and traumatized and inflammed tissues to provide ammunitions for macrophages to do their work and relinquish the waste and end products for disposal. I don't read French (see below if you do).

    Once HDL and LDL are done, they can re-enter the blood stream, return to the liver for future processing.







    Ubiquinol Protects Against Failure of the Heart and All Organs

    Ubiquinol is lowered by statins since ubiquinol and its derivatives are cholesterol structures [ref 19]. Unfortunately ubiquinol is necessary in all cells and mitochondria where it serves a role as mandatory antioxidant and a recycling nazi [16-18]. Low ubiquinol in the blood is associated with faster progression of heart failure [ref 17].

    Statins lower the LDL contents of ubiquinol and all fat-soluble nutrients, vitamin E and carotenoids. Does this have consequences?

    Prior animal pharm: Role of Ubiquinol



    Higher the Cholesterol, Higher the CHF Survivorship


    Our understanding of survival and the evolution of insulin resistance provides the foundation to understand the causes of all diseases of modern civilizations including CHF. The studies bear this out in which the higher glucose and higher insulin resistance, the higher the association to mortality in CHF [ref 12-16]. Interestingly several studies demonstrate the lower the cholesterol, the higher the CHF mortality. Some clinicians raised the potential risks of statins in light of these adverse outcomes in individuals with CHF [ref 31].

    In patients with progressive CHF, their LDL are all small packages which can barely hold vital antioxidants like ubiquinol. Add a statin which deplete the crucial functioning ubiquinol for pumping heart muscles, spelling catastrophe.




    Low Cholesterol Associated With Increased Cancer Incidence: 17-Year Basel Study 

    The prospective 17-year Basel study showed a 2-7 fold increase in cancer mortality in males at various cancer sites with low serum cholesterol. This study confirms what some of the other cancer epidemiology studies have already shown. Researchers tested blood from 2974 participants stored from 1971-1973. Co-founders such as vitamin blood levels were adjusted for in the analysis.

    Quality will always trump quantity of LDL.

    Carcinogenicity of Statins: The Lower the Final LDL, the Higher Cancer Rate


    Finally the statin and lipid-lowering drug trials themselves have demonstrated that the lower the cholesterol, the higher mortality from cancer in a meta-analysis in JACC, 2007 by Alsheikh-Ali et al [ref 27]. Plotting final LDL with cancer, the graph depicts a firm association between the lower the LDL and increased cancer incidences.

    Good post, thanks for your continued work in this area. Being an E4/E4, I always like to read more about it, even if there's chance it is just confirmation bias. Have a good one.

    I think you mis-cited the last paragraph? Ref[27] is a meta-analysis of rodent studies, but the figure you posted is from: "Effect of the Magnitude of Lipid Lowering on Risk of Elevated Liver Enzymes, Rhabdomyolysis, and Cancer", which you didn't cite.

    Great post and good to hear from you again. Everyone needs to know this stuff. Seems to me some interventions - fish for example - might lower LDL (maybe, I'm not certain it does) - in ways that don't compromise health (activation of PPAR-alpha meaning slightly more fat burned in liver instead of exported). Others might elevate LDL (eating a big chocolate cheesecake everynight) but compromise health due to glucose-insulin loads and empty calories. So it's not the rise or fall in LDL per se, but whatever caused it. And as very different things and different processes can cause similar-looking changes in LDL and HDL we should ask are those THINGS desirable in our lives - and bugger the cholesterol numbers they result in. A cholesterol number should never cause you to consume a harmful thing or avoid a nutritious one. IMO.
    Dr. B G said...
    Anon -- Thnx! Fixed. Both statins and controls actually have increased incidence of cancer at the lower LDLs. In rodents any dose of statin is carcinogenic. Humans are different but I'm not sure how. George, I appreciate the posts on your blog as well. FASCINATING STUFF ;) Yes I try not rely on labs but sometimes one has to (love/hate). Being in China, obtaining labwork is challenging to say the least. For instance many on statins have no idea they are doing harm to each and every mitochondria (particularly liver ones, no?). Muscle punch biopsy studies have demonstrated damage to muscles due to statins despite totally 'normal' CPK. Phillips PS, Haas RH, Bannykh S, Hathaway S, Gray NL, Kimura BJ, et al. Statin-associated myopathy with normal creatine kinase levels. Ann Intern Med 2002;137:581-5. England JD, Walsh JC, Stewart P, Boyd I, Rohan A, Halmagyi GM. Mitochondrial myopathy developing on treatment with the HMG CoA reductase inhibitors - simvastatin and pravastatin. Aust N Z J Med 1995;25:374-5. Labs are just a surrogate for what a person is trying to discern objectively. http://drbganimalpharm.blogspot.jp/search/label/SHOW%20ME UR RIGHT ON. So many limitations! I enjoyed your example of trends with fish v. cheesecake. Depending on the person (E2 v. E4) LDL may go up or down!

    Objective ways to assess function and health of mitochondria (and statin damage) is to measure mitochondrial CoQ10, TCA and Kreb cycle intermediaries and organic acids. http://www.metametrix.com/learning-center/articles/2006/why-test-for-coenzyme-q10
