The Definitive Guide to Cholesterol

cholesterol 1

That makes it easy.

With all the talk of fighting, battling, combating and beating cholesterol into submission, you’d think it had a black plastic body suit and James Earl Jones’ voice. Big Pharma has, dutifully created quite an arsenal for our supposed defense, and the medical community has been a willing faction, delivering the rhetoric that would incite us all to pick up arms. Now if only we could put down the Big Macs. And the Ding Dongs, HoHos, Twinkies and…you get the point.

But the insidious rogue, that menacing villain isn’t to be found at the helm of the Death Star. Turns out, there is an enemy within and it’s not even cholesterol. Before you fall to your knees, rip your shirt and gnash your teeth, you might want to consider news you don’t hear often enough: the much aligned compound in question is absolutely essential to your physical, psychological and cognitive functioning.

Yes, the message these days seems to be that no number is too low when it comes to cholesterol (except HDL but we’ll get to that later). I’d like to offer a deeper look into the issue, user-friendly enough but more complex and contentious than you’ll get from the commercial sound bytes telling you to talk to your doctor about blah, blah, blah. Consider it one of MDA’s definitive guides that we’re happy to serve up for our gregarious and always thoughtful community.

Excuse me, have you met cholesterol?

cholesterol1

Cholesterol is a waxy, charming lipid gracing every cell’s membrane and our blood plasma. Its jobs, which are many, include insulating neurons, building and maintaining cellular membranes, metabolizing fat soluble vitamins, producing bile, and kick-starting the body’s synthesis of many hormones, including the sex hormones. Cool stuff actually.

Given all the work cholesterol has to do, the liver is careful to ensure the body always has enough, producing some 1000-1400 milligrams of it each day. In comparison, the 300 milligram recommended limit for dietary cholesterol (your tax dollars at work in the USDA) is a drop in the bucket. And get this: our livers come with feedback mechanisms (at no additional cost) that regulate cholesterol production in response to our dietary intake. When we eat more, it makes less, and vice-versa. Imagine that!

(Interesting note: While animal products like meat, eggs and dairy, are far and away the primary source of dietary cholesterol, plants contain trace amounts of cholesterol and cholesterol-like substances called phytosterols, which may help lower blood or “serum” cholesterol. Not that that matters, as we shall soon see.

So, what’s with all the acronyms on my cholesterol profile, you ask. Let’s take a look. First, there are high density lipoproteins (HDL). (Lipoproteins are spherical fat particles with water-soluble proteins around their exterior. They transport cholesterol). HDL: everybody loves this guy. He has the popular job of transferring cholesterol from the body’s tissues back to the liver. It’s basically the end of the line with this route, and the liver then excretes it through bile. HDL is the one to naturally help get rid of excess cholesterol when the body’s done with it, hence his universal popularity. Some cholesterologists (just made that up) even refer to him as Nature’s garbage truck.

Next, there are low density lipoproteins, LDL. LDL is a lipoprotein and delivery man as well. He has the disgraced job of transporting cholesterol after production from the liver to the body’s tissues. Remember, this is an important job! That cholesterol has a honey-do list a mile long.

Ironically, it turns out that it’s not the cholesterol part of the LDL or HDL moiety that is dangerous, but the actual lipoprotein part. Unfortunately, once medicine had found a way to differentiate between the amount of HDL and LDL in a cost-effective blood test, it was the cholesterol part that got the short end of the deal.

The latest research into LDL shows that there are actually sub-categories of this cholesterol transporter and that some are more dangerous than others. The larger, more billowy LDL particles are now thought to have little or no significant role in heart disease. On the other hand, the smaller, dense LDL particles are the ones believed to be most involved in the process of inflammation that begins the atherosclerosis cascade. And wouldn’t you know it, but it’s a diet high in simple carbs that most readily promotes the formation of these small LDL particles! Unfortunately, this important distinction is probably something your doctor knows very little about, yet it’s the number of small particle LDL that might be the most important reading in any cholesterol test. So a total cholesterol of, say, 230 or even 250 might not be dangerous at all if your HDL is high and your small particle LDL is low.

Before we move on, let’s give brief mention to triglycerides. Triglycerides are essentially the form that fat takes as it travels to the body’s tissues through the bloodstream. The relationship between triglycerides and cholesterol is more of an association. A high triglyceride level, which is unequivocally fueled by a high carb diet, is very often a marker for other problems in the body, particularly insulin resistance (and accompanying risk of diabetes) as well as inflammation (with its risk of heart disease). High levels are often seen with low HDL cholesterol. Once again, the high carb diet wreaks havoc.

The Rise of Cholesterol Panic

cholesterolfree

Heart disease took off in the early part of the twentieth century, and doctors frantically searched for the cause throughout the next several decades. Tests in the fifties initially showed an association between early death by heart disease and fat deposits and lesions along artery walls. Because cholesterol was found to be present in those deposits (of course it would!) and because researchers had previously associated familial hypercholesterolaemia (hereditary high blood cholesterol) with heart disease, they concluded that cholesterol must be the culprit. In fact, what happens is that in response to an inflammatory situation, the body uses cholesterol as a “band-aid” to temporarily cover any lesions in the arterial wall. In the event the inflammation is resolved, the band-aid goes away and repair takes place. No harm, no foul. Unfortunately, in most cases, the inflammation proceeds, the cholesterol plaque is eventually acted on by macrophages and is oxidized to a point at which it takes up more space in the artery, slows arterial flow and eventually can break loose to form a clot. And all this time the cholesterol was just trying to be the good guy! Blaming cholesterol for all this is like blaming a cut finger on all the band-aids you have lying around your house.

Death from heart disease, according to the CDC, has declined over 50% since its peak in the 1950s. The success is attributed to a number of factors, including a decrease in smoking and better diagnosis and treatment of high blood pressure. Included in the list of factors was the opportunity for public education regarding the scientific findings/theories related to cholesterol; however, measures (including CDC estimates) of dietary saturated fat intake show that intake has generally stayed the same or risen.

But the dietary cholesterol message stuck.

Big Pharma To The Rescue!
Early drugs that “battled” high cholesterol prevented its absorption in the digestive tract. The side effects on the digestive system were unpleasant enough and the results modest enough that the drugs never garnered much support from either side of the prescription pad. Enter statins. Statins inhibited the natural production of cholesterol. Side effects were not as immediately noticeable or uncomfortable, and the results were quite good (at least at lowering cholesterol). (The recently beleaguered Vytorin and Zetia combined statin actions with a substance that reduces absorption of dietary cholesterol, preventing your body from trying to compensate for the lower natural cholesterol production.)

But what about the body’s natural impetus to produce a given and necessary amount of cholesterol? What happens to the parts of the body that need the cholesterol? What about the liver’s regulating mechanism? What happens when you mess with evolution? Exactly. Those are the sorts of questions that get thrown aside when you’re riding Big Pharma’s cholesterol hobby horse.

What Are the Problems With This (“Lipid”) Model?

question

Oh, boy. There’s the million dollar question.

First off, let’s go back to the evolutionary question. As a naturally self-regulating system, the body will react if it doesn’t have enough cholesterol (yes, the body’s definition of enough and not Merck’s). If there’s not enough cholesterol, the alarm goes off, strobe lights flash and the body goes into crisis mode. Corticoid hormones coordinate a redistribution of cholesterol, a triage of sorts in which cholesterol is rationed among the many areas of the body that need it. Nonetheless, the body is now working under hardship conditions.

Adequate cholesterol isn’t available for the body’s repair system, for the uptake of serotonin, for the full initiation of Vitamin D and hormone production and their regulation of blood sugar and inflammation, etc., etc. What does your logic tell you here? Yup, nothing is running the way it should.

Let me also add that everyone’s cholesterol profile is going to be different, no matter what. And I acknowledge that a very small percentage of people out there genuinely have *true* hereditary high blood cholesterol, familial hypercholesterolemia, a metabolic condition with impaired or even lack of ability to metabolize cholesterol. This condition can have serious health consequences. By the way, this condition, in its heterozygous form affects at most 1 in 500 people. Total serum cholesterol in these folks is in the 400 mg/dl range (as opposed to the 200 recommended). The homozygous form affects about 1 in 250,000. You likely don’t know anyone in this category because their disorder almost always ends their lives at a very young age.

I mention familial hypercholesterolemia because I want to distinguish it from the claim made by Big Pharma ads that you may have higher cholesterol because people in your family did, and – can you believe it – their company is here to help. Duh! Everyone’s family influences cholesterol profiles. It’s, in small part, genetic. No big worry there. Just because you come from a family with “elevated” cholesterol doesn’t mean you have the familial hypercholesterolemia metabolic disorder. You can pretty much bet a whole lot o’ money on the likelihood that your cholesterol profile – good or bad – has more to do with learned behaviors like diet and exercise. “Elevated” cholesterol doesn’t equate with metabolic disorder.

Officer, You Got the Wrong Guy!
I’ve said it before, and I’ll say it again. Sound and reliable medical research hasn’t proven that lowering (or low) cholesterol in and of itself reduces risk of death from heart disease across a population. Yes, there is always that single isolated guy who throws off the curve, but he (or she) is a statistical anomaly and doesn’t negate the legitimacy of the model. For instance, the Japanese people of Okinawa are among the healthiest in the world. Their heart disease rate is extremely low, but they tend to have “elevated” cholesterol levels.

The fact is, half of all first time heart attack sufferers have a perfectly “normal” cholesterol profile. What does this tell you? There must be some other piece here behind the “other half” and, I would solidly argue, behind the first half. Cholesterol is a red herring.

It all boils down to inflammation. Inflammation is the number one factor in heart disease. This is an accepted fact now, but it still gets little attention and no real prevention or treatment. Think about it: you have your cholesterol levels checked every five years or more if your profile is “problematic.” When do you have biomarkers for inflammation checked? Unless you’ve had a heart attack or been diagnosed with a serious medical condition, probably never.

Inflammation. What is it caused by? Not fat, but carbohydrates. Yes, sugars and processed carbs are highest on the list of perpetrators here, but grains and starches as a whole contribute to the problem. LDL rises directly not with the amount of saturated fat you eat but with rising levels of inflammation caused by carbs and trans fats.

Oxidation. Furthermore, nearly every study suggests that LDL is only a true threat when it’s oxidized. What oxidizes it? Free radicals. We’re talking trans fats primarily, that beast of an additive found in countless food products (as opposed to foods). What counteracts free radicals (because we all naturally have some in us)? Anti-oxidants: veggies and fruits, of course, as well as nuts, olive oil, etc. Consider also a broad-based multi-antioxidant supplement containing those nutrients shown to decrease oxidation.

Back to the red herring issue. Substantially “elevated” cholesterol, low HDL or high LDL might be reason to give you pause, but not for the reason you might think. The number can tell you that something is amiss, but they’re a symptom of the larger concern rather than the main issue itself. Cholesterol profile can be impacted by other conditions such as hypothyroidism, untreated diabetes or pre-diabetes, pregnancy (surprise!), lactation, stress, liver conditions, heart disease (symptom, not cause of), etc. Talk to your doctor about what your numbers mean in the grand scheme of your health. And see if you can get a read on other markers, like C-reactive protein (an inflammatory indicator) and those small particle LDL numbers.

How to Maintain True Heart Health

heart 1

Now that we’ve conquered the cholesterol frenzy (because the frenzy itself is the real threat), let’s get to the genuine issue of maintaining heart health. Maintaining heart health is about keeping inflammation at bay. As we say here at MDA, that means an anti-inflammatory diet (with exercise), and primal nutrition fits the bill: copious amounts and variety of veggies, fruits, good quality meats, healthy fats and proteins.

Also, plenty of omega-3 fatty acids, particularly fish oil, will thin the blood and help prevent clotting, which along with atherosclerosis (inflammation related), is a serious set up for heart disease and stroke. Fish oil also happens to generally lower triglycerides and increase “good” HDL.

Read up in our MDA archives for additional info on inflammation and healthy living. Thanks for tuning in.

    • Our current “common knowledge” is created by advertisers to sell processed foods, degraded meats, fruits and vegetables, and medicines. Not so good, huh? The idea here is to find comfort in the foods human beings ate safely and productively for millenia and to determine whether or not your genetics enable you to tolerate some of the things that came along in the last few thousand years. So you’re really returning to common knowledge, not flouting it.

My cholesterol’s borderline high already, but wouldn’t eating all those eggs make it even worse? I read through this page and the posts, and it’s the posts where people’s bad levels of cholesterol went Up that worry me, because how would you ignore That? I know cholesterol is beneficial for different things, but too much of anything, esp HDL isn’t good!

    • I’m a bit of a geek, so I already had a spreadsheet with food values from the USDA National Nutrient Database. With that spreadsheet and a set of scales, I was able to determine how much fat (& which types), protein and carbohydrates I ate.

      I pretty much eat the same breakfast, lunch and snacks everyday, so I decided to change my diet slowly. This was important for me because adding fat to my diet allowed my body to handle the additional load intestinally.

      Gaining weight has never been my goal (just the opposite). I can provide advice on unhealthy ways to gain weight, so I can’t help you there.

  4. Have you read Anthony Colpo’s “The Great Cholesterol Con?”

    Not to mention the simple fact that 75% of people who have heart attacks have normal cholesterol. The lipoid hypothesis used 7 countries when there were 22 countries with data available. Also, if you look at MONICA, the fact you can keep the cholesterol myth alive is just astonishing, as there is little-to-no correlation between deaths and cholesterol.

    Other good reads were Dwight Lundell’s “The Great Cholesterol Lie” and Uffe Ravnskov’s “Fat and Cholesterol are good for you.”

    I haven’t believed the cholesterol myth for quite some time, nor the “Metabolic Syndrome” or “Syndrome X.” There was also a post in the Colombo Herald where I read they were going to put statins in our fast food! What in the world? And also they recommended kids as young as 6 have statins, sure, money is definitely not a factor.

  7. Well, looks like I’m not alone in this. :)
    After about 2 months in a non-radical Primal lifestyle:
    # Fasting Glucose = 86 [mg/dL]
    # Blood Pressure: 90 / 50 [mmHg]
    # Total Cholesterol = 275 [mg/dL]
    # HDL = 56 [mg/dL]
    # LDL = 210 [mg/dL]
    # Triglycerides = below 90 [mg/dL] (too low for the chemist’s machine to get right)

    Now, I’ve stumbled upon a very interesting article that clarifies that the most telling indicator of CVD risk is actually TG/HDL. If you’re below 2.0, you’re ok.
    http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2664115/

    Assuming a TG count anywhere between 70 and 90, this yields for me:
    # Trigl./HDL = 1.25 ~ 1.60

    So, although the doctors in my family are scared about my LDL=210, I’m ok with it because I know that I have a pretty low Trigliceride level and a relatively good HDL. Plus, the blood pressure is pretty low. And, of course, I’ve become pretty leaner and stronger too.

    The reason I speculate a 70 < TG < 90 is because I had TG=73 a couple of years ago when doing Paleo (without sat fat). And now that I'm doing Primal with lots of sat fat and very little carbs, I expect to see the TG drop even lower.

    So, Mark and all the guys and gals here, what do you have to comment on this study I linked up?

    Vasco Nevoa wrote on August 30th, 2011
  8. Mark, There has been substantial evidence that saturated anima fat promotes arterial disease. Even so-called grass fed beef. There was a man who was on the Atkins diet who sued Dr. Atkins when he developed heart disease after 1 year on his high fat animal diet. For that reason I do not eat red meat, instead I eat lean turkey breast which I boil in hot water to reduce the fat even more. I do think your understanding of the correct diet for the human specie is right on the money.. However, too many carbs can easily sabotage this diet. Grok was, after all ,on a very low carb diet with only seasonal fruit as his main carb. Please respond, thank you

You know, even if Mark and the hundreds of thousands of paleo/primal eaters in the world, not to mention the millions of ancestors throughout history turned, out to be wrong, I’m OK with it. I’d rather die young, happy, and well fed than live to be a 100 eating the disgusting crap you just described.

  9. Of course, what is so scary about all this cholesterol con is now the ‘scientists’ are using teleoanalysis to prove that cholesterol causes heart disease. Teleoanalysis “provides the answer to studies that would be obtained from studies that have not been done and often, for ethical and financial reasons, could never be done.” Law and Wald – Combining data from different types of study. So this means that you can prove things you know to be true despite there being no studies done. Awesome.

      • Interesting. Sorry about the insurance thing, but good to hear you feel well.

        In my case, I wonder whether the cholesterol is elevated because there’s some sort of healing going on, or whether I do just eat too much for me at the moment. My results were marked “severe hypercholesterolaemia in the range associated with FH (familial hypercholesterolaemia)..but noted “normal trigylcerides, TSH and glucose”, so as to underscore for my GP it’s not being down to issues with diabetes or thyroid, I would think.

  13. I have been following this discussion with great interest. I am not a doctor, and I don’t think you will get a doctor or Mark to comment on the cholesterol numbers reported here. But I say that if you have total cholesterol in the 300 and 400 range, you are in trouble, and are either doing something wrong or this is not for you. No Grok ever ate a steak with butter, or butter for that matter. They were all lactose intollerant. And they never ate coconut oil, olive oil or any other kind of oil. These are all refined foods that strip one element from its dietary context. How many olives do you have to eat to get 2 tablespoons of olive oil? Not that a Grok ever ate an olive, because you can’t eat them off the tree.

    I think its a huge mistake to conflate the low-carb thinking with paleo. Low-carb accepts many western diet precepts (e.g. refined oils and factory meat) that paleo does not.

    I drove my total cholesterol from 214 to 141 in 8 mos. on grass fed buffalo and beef and fish no more than twice a week, oat bran and berries for breakfast everyday, zero dairy, very little sugar, and otherwise cooked whole grains and tons of vegetables and beans (almost every meal). Basically, I tried to zero out saturated fat from sources other than fish and meat, and boost fiber to 50 – 60 grams per day. It was easy, but it’s only the starting point. I think paleo may offer the long term solution and I am going to work this to see what effect it has on my physiology. One of these days I will post my food logs.

    Don’t trick yourself into thinking you can survive with blood chemistry that far out of whack. This is supposed to solve the western diet problems, and if it is not, don’t stick with what you’re doing.

    I hope this isn’t seen as negative, it’s not meant to be, but some commenters are reporting serious health concerns, and they should not be glossed over or ignored.

    • fyi … low cholesterol (generally defined as less than 160, more likely less than 180) is not good for you. Increases risk of hemorraghaic stroke, vitamin d deficiency , problems with hormone production, etc etc. you might try letting your cholesterol go back up a bit.

      Here’s an article from aha (1995 no less!) to back up what i’m saying. you can google cholesterol deficiency too: http://circ.ahajournals.org/content/92/9/2365.full

The above finding for cancer mortality agrees with results from the Multiple Risk Factor Intervention Trial,4 in which participants who died of cancer experienced within 1 year of death a fall from baseline in serum cholesterol level that was 22.7 mg/dL (0.59 mmol/L) greater than that of surviving participants of the same randomization group and smoking status. These results also support longitudinal data published by Pekkanen et al57 from the Seven Countries Study in which a decline in TC also tended to be associated with death caused by cancer among the older cohort. A decreasing TC also was associated with elevated overall mortality and cardiovascular mortality in both men and women in the 30-year follow-up of the Framingham Study.58"

    • Having been put on statins and egg-whites only with white meat occasionally, for some 10 years, my LDL came down from approx 200 to 86 last year. I thought it’s the time to try out whether I was one of the minority who was a hyper-responder to dietary chol, with 1 whole egg daily and red meat occasionally. Turns out I was, for LDL went to 175 in a year, TC to 250, and HDL only marginally from 44 to 49.

      I now feel the urge to try out the theory that it’s inflammation that should be monitored, not chol. Have found CRP is -ve, and if homocysteine is also low, I’ll feel free to carry on with the modified diet.

      However, at what stage should one think that the blood chemistry is “…blood chemistry is (too) far out of whack…”. Should it be at TC of 300, and LDL of 200, or what? Would appreciate views and guidance.

  14. I’ve always maintained a healthy diet and have been pretty athletic. This year, at age 52, I a had a stent placed for a coronary plaque. I had chest pain while on a group training ride on my road bike ! I’m now on 40 mg Lipitor, which I freakin’ hate – my neuromuscular system has gone way down hill (many crashes on rides I used to have no difficulty with on my mountainbike) My cardiologist won’t decrease my dose because of the whole stent thing. I take coQ10 and pycnogenol. Do you have any other recommendations ?

    • How do you define “healthy diet”?

  15. Been trying to get my head around this subject of cholesterol. I finally understand! This article is Brilliant!!! Thank you. I am emailing it to a number of ppl :)

  16. I’m checking back into this discussion because 4.5 months after adopting the Paleo diet, I got some blood work done and wanted to share the results. Unfortunately, this same time frame has been exceptionally sedentary, but I am just starting to ramp it back up, and am looking forward to incorporating some Mark’s idea’s into the mix.

    2/5/2010
    Weight: 200
    Total: 189
    LDL: 132
    HDL: 42
    Trig: 74

    4/17/12
    Weight: 165
    Total: 144
    LDL: 97
    HDL: 39
    Trig: 41

    So far, so good! If (and its a big if) a lower cholesterol profile means there’s less chance of CAD, then this approach to diet and nutrition appears to be the answer, at least for me. And this should keep the MD’s from trying to get me on a statin which they were threatening several years ago when my totals were over 200 and trigs around 100. Oh yea, age 50.

    The remarkable thing is the lower Trigs. It appears the critics may be correct and that sugar and refined carbs drive that (and LDL) higher, not dietary fat.

  17. I am 37yo, 155lbs, 5’11”.
    I have always lived in Italy, using a pretty diversified diet, no excesses, no sodas, and you can imagine a lot of “pasta”.
    From 2006 to 2009 I lived in the US, where I had plenty of meat-burgers-steak-porterhouse, etc etc, terrific meat.
    I took my blood test in 2009 and both my total col. and trig were pretty high.

    After I got back on track with a diversified mediterranean diet (no excess of read meat, no more than 2 eggs per week) my levels improved, and all the “ratios & indexes” are ok. My latest results are the following:
    Col ToT: 260
    HDL: 90
    LDL: 167
    trigl: 67

    I’d like to lower my LDL, but I dont know where to tackle my diet, which seems pretty good. I dont even eat pasta that often anymore, once a week at most. Not a big eater of cheese either.
    I spoke with many australian friends, and they all eat 2 eggs every day for breakfast and they are fine. I read that 20% of our Col. comes from food, and the other 80% is ereditary.

    • Dr. Krauss, who originally discovered the subcomponents of LDL, indicated that LDL count – as derived by current lab tests/procedures – is basically a useless number. He states it would be better to pay attention to your HDL number.

      HDL counts were inversely related to the small-partical dense LDL. So, high HDL corresponds to low small-partical LDL. Low HDL corresponds to high counts of small-particle LDL.

      The interview can be found here:

      I haven’t read anything newer (the interview is 2010), so I’m unsure what new research he’s done.

  18. I’ve read thru these replies until my head hurts, and I’m a paramedic. I just never cared much about the finer points of cholesterol when someone is bleeding to death. My question is simple: Can eating the healthier PB diet with foods such as avocado’s, nuts and organic proteins in higher quantities (because I don’t eat carbs and I get hungry!) cause your overall cholesterol to rise? Mine did about 50 points after eating primal/lower carb for about a year. Everything else measured great but total cholesterol went to 228. I’m not worried but I am curious and I’m sure others are also. I do love avocado’s and I have been known to make a meal of them. I also eat salmon and fish very regularly.

  19. Great article! I have just recently listened to audio talks of Dr Ross Walker (Aus Cardiologist), Prof Peter Dingle (Aus Toxicologist & Author), and especially Bill Davidson (Naturopath and Chiro) who ALL subscribe to this theory. Davidson almost word for word (without the humour) describes this very phenomenon. Just to add some more advise, if your ratio of HDL:LDL is 1:5 (e.g. cholesterol level is 7 but with 2 HDL to 5 LDL) it is perfectly normal. Yet a doctor would say a level of 7 is bad. Like Seth Godin would say, BROKEN. Let’s keep the Grok health community alive.

  20. Yes! I have the same problem with my doctor, refusal to learn anything he doesn’t read in a biased medical journal. Even the great Dr. Oz is seeing the cholesterol myth exposed for what it is which I give him so much credit for his willingness to correct a wrong way of thinking.

  21. After 3 years of lowcarb/primal eating (around 185g proteins + 170g fat + 140g carbs daily for the last 8 months), my lipid profile looks like this:
    – TC 220
    – LDL 106
    – HDL 110
    – Tri 22
    Also, no more running, only walking 5 km/day and strength training 2 x 1 hour/week.
    Of course, the TC value of 220 was underlined by the doctor for being too high :D
