The Cholesterol Lie: They'll never let it go

If you've read anything by Uffe Ravnskov, you'll know that cholesterol does not cause heart disease. So, when I read this article this evening, I thought, they'll never let it go will they?

Fat Alone, Not Where It Sits, May Be Key to Heart Problems

"That challenges the widely adopted notion that not all obesity is alike, with so-called apple-shaped people, who carry fat mainly in their midsections, facing a bigger risk for heart problems than those whose excess fat is carried on the hips or elsewhere.

Not so, say the researchers behind the new study. When it comes to obesity and heart disease, no excess fat is good fat, regardless of where it ends up, their analysis has found.

"Society has accepted the idea that if you carry more weight around the middle, your risk of heart disease is higher," said Dr. Emanuele Di Angelantonio, the study's co-author and a lecturer in medical screening at the University of Cambridge in England. "But actually this study shows that it doesn't matter where your fat is located. If you're overweight you're at risk, full stop."...

They also found that tracking a person's blood pressure and cholesterol levels, as well as monitoring their history of diabetes, appeared to be best way to assess heart disease risk. When such indicators were readily available, they noted, adding in BMI and waist measurement information did not improve risk diagnosis..."

So, basically they do mention that diabetes is a risk factor for heart disease. What causes diabetes? Elevated blood sugar over a prolonged period of time that causes insulin resistance. What causes elevated blood sugar? Eating carbohydrates. Bleeding simple, and yet they're like Don Quixote, tilting at windmills. Forget testing for cholesterol. It's irrelevant! Test for blood glucose levels instead. That would give a better idea of whether someone is healthy or not.

If you are overweight, then you probably have elevated blood sugar and/or are insulin resistant. In fact, I'm not sure that it's possible to be overweight and NOT be insulin resistant. Hence why being obese is associated with cardiovascular disease, because every time your blood sugar is elevated, you are damaging your internal organs. Yes, you read that right. Every time you drink a Coca-Cola, every time you eat a piece of chocolate cake, you are DAMAGING YOUR INTERNAL ORGANS. In fact, even if you are not overweight and even if your insulin works well and it brings your blood sugar down quickly, it is probably never quick enough to completely avoid the damage that is done. Add this up over days and years, and you have cardiovascular disease. Not to mention all the other disease of civilization, like cancer. If you damage your cells repeatedly, they repair or regenerate themselves. If your cells are required to do this frequently, the cells regenerate quickly, leading to high cell turnover, leading eventually to a cell that doesn't regenerate in the right way, which leads to cancer.

The good thing is, your cells will repair themselves if given a chance. The bad news? You can never go back to eating the way you did if you want to remain healthy. You have to ask yourself what is more important. The slice of chocolate cake or your health? Death is inevitable. Health is your choice.

zOMG... you're all obese!

I read about this yesterday. They have a new method they want to use for measuring obesity, called the Body-Adiposity Index. Now it hit me today, that if they do this, every woman on the planet will be obese. Isn't that what the pharmaceutical companies want? I hear there's a huge market for diet pills.

This method is so flawed, on multiple levels. First of all, it doesn't take into account Lipodystrophy, where body fat is stored in a particular location and not evenly throughout the body. I've seen men with humongous beer bellies that wear size 30 pants because their bellies hang out over their pants. Their hips are normal. So with this method of measurement, they'd not be overweight.

This method of measuring obesity sounds as much, if not more so, codswallop as using Body Mass Index as measurement.

I think measuring people in certain multiple locations could give a better idea about obesity, but not by merely measuring their hips. And I'm sure that even that would be flawed in the case of body builders. BAI is obviously very flawed in the case of men, who typically do not store fat in the hips. The storage of fat is driven by hormones, insulin and the sex hormones estrogen and testosterone. According to the measurements you're supposed to get with BAI, they've taken into account that men's hips are supposed to be smaller... maybe absurdly so.

The interesting thing is, the mum-in-law, hubby and I calculated our BAI using the formula given on various websites which is [hips in cm / ( height in m^1.5)] - 18. When we did the math, I came out with the number 32.08, the mum-in-law had 31.49 and the hubby had 26.07. I had a difficult time finding what the ranges were for normal, overweight and obese, but the one site I found that gave them says that I'm slightly over-weight, and that the mum-in-law is nearly so. Which is utter codswallop. She looks like a perfectly normal weight, and if you use the BMI she is, with a BMI of 22.5. My BMI is 26.6, which is reasonable, as I'm still a little overweight. I could definitely stand to lose another twenty pounds and am working on it.

Now we get to my husband. According to this silly equation he's obese. More codswallop. Men have more muscle mass than women (muscle is denser than fat), even if they don't lift weights, and he does not look obese. He looks overweight to be sure and could definitely stand to lose some weight, but if he had the numbers they want, he'd have to look like a skeleton to do it. To be in the middle of the normal range using the BAI he would have to lose 20 cm, or 7.8 inches. I don't think he could lose that much in his hips, as most of the extra weight he's carrying is in his stomach (like with so many males) and he's got a very large frame to begin with.

Just as with BMI, the BAI doesn't take into account body type or skeletal frame, and is therefore flawed. Honestly though, the true measure of health should have little to do with weight. I believe that blood glucose levels would give you a better image of how healthy someone is rather than how much body fat they have or don't have. This is something that Dr. Eades implies in Fat Head, when she says that the hardest person to make realize that they need to change the way they eat is the one that has metabolic syndrome/elevated blood glucose, and yet their weight is normal.

Fructose and Fetal Harm

Via a comment on Fat Head:

A commenter on Fat Head left a link to this article, from New Zealand that fructose may affect the development of female children. Sucrose (table sugar) is half fructose, and High Fructose Corn Syrup is more than half fructose, depending on the mixture. And I need not point out that HFCS is in just about everything that's manufactured or processed. They slip it into the most innocuous places. Fructose also occurs in fruit, something that a lot of doctors push people, especially diabetics, to eat (detrimentally to their health I might add).

A lot of pregnant women may think that because they're not overweight, or they don't have gestational diabetes, that it's okay if they consume large quantities of sugar or fruit. They often use the fallacy that because we've been consuming sugar for a long time, it's not a problem. The thing is, we've not been consuming sugar or fruit in the quantities we do for very long. Sugar consumption in the past thirty years has skyrocketed to 150+ lbs per person per year in the States, whereas in the 19th century sugar consumption was only in the 15 to 20 lb range per year before 1850. And even just fifty years ago, most people only ate fruit when it was in season, which in most parts of the world is a limited time frame. I'm sure with the powers-that-be and doctors pushing fruit consumption, that it has also risen.

Is fructose safe?
"In the study, where rats were fed diets high in fructose during pregnancy and lactation, the sugar was found to change key metabolic hormone levels in both foetuses and new born offspring...

The fact that we saw no obvious weight gain implies that women may be unaware that their diet could be compromising the development of their fetus."

They don't say what metabolic hormones are affected specifically, but I'm thinking insulin is probably one of them. Now, I also read a study not too long ago that female rat offspring were also affected by maternal dietary salt restriction. Another thing that the doctors push on us, lower your salt intake they say! Salt restriction in the mother made the female offspring insulin resistant with increased adiposity (fat). The male offspring were not so affected. Does this mean that there would be nothing to worry about with males then?

I doubt it seriously. I read that in indigenous populations, such as the Pima, female hormones somehow protect women from getting diabetes, at least for a while. However, they get very obese instead. Eventually they get diabetes, but not before getting fat. It is theorized that the fat protects them from diabetes as long as their bodies can continue to convert excess sugar in the blood to fat and store it. Now, the men don't necessarily get as fat as the women, but they have an increased incidence in developing diabetes.

I'm glad to see that a news organization actually published something that goes against the party line. I guess they don't grow much corn or sugar in New Zealand. I'm waiting for one of the American news organizations to pick this up, but I won't hold my breath. Asphyxiation is no way to die.

Cognitive Dissonance and Obesity Research

After reading about obesity in children, since it's Heart Month there's a ton of obesity articles in general going around, I got to looking for scientific journals on the subject. One of the better articles is "Obese babies and young children: an approach to paedratric management" from the British journal Paediatrics and Child Health, Volume 19, Issue 9, Sept 2009, pages 425-429.

They actually say that the "energy in/energy out" that is used to justify why people should be blamed for being overweight is "too simplistic an explanation..." They even mention insulin insensitivity (resistance) as predisposing a child to gain weight. Amazing!

And then what do they do? They go on to say that "Hormonal causes of obesity are also extraordinarily rare." and "...however, at present identifiable metabolic and hormonal causes are exceptionally rare." I'm hoping that they're excluding insulin from this, as last I checked, insulin is a hormone and is very much responsible for most people's weight problems.

Later in the article they elucidate one reason why people may not be motivated to change their lifestyle.
"Unfortunately research shows that parents too often find that health professionals (and particularly doctors and dieticians) are critical, judgemental, blame them for their child's obesity, make them feel guilty, or are dismissive."

Well no duh! Especially when most nutritionists and people in general act like it's your fault that you're fat or your kid is fat. When you're eating corn syrup and sugar from the first day of life, what do you expect to happen? This isn't their fault, it's what they're being told to eat. It's what they're being told to feed their children.
"Babies are born with a natural ‘fuel gauge’ which signals when enough has been eaten. Unfortunately this gauge is often overridden by the way children are fed, which contributes to the development of obesity."

I don't think it's the way they're being fed, I think it's what they're being fed. They still talk of limiting food intake, contradicting what they said at the beginning of the article about how "calories in/calories out" was too simplistic of an explanation. They do say to avoid juice and stick with food that are of a low glycemic index, which is good, but I think doesn't go far enough. This is cognitive dissonance, which runs rampant through the field of dietary and obesity research. I guess old habits die hard.

Baby Formula is Junk Food: A Not-So Good Start

Not having children, and I would breast feed if I did, I never realized what was in baby formula. Have you looked at it?

Now knowing that sugar and refined carbohydrate consumption cause insulin resistance, which in turn causes diabetes and a host of other metabolic problems, you would that that baby formula would be the last place you'd find said ingredients.

But no! I, as an adult, wouldn't consume what's in baby formula, and yet people are feeding it to their children, probably because they think don't have a choice.

Out of many of the formulas I looked at on the shopwell website, which will give you nutrition facts and ingredient lists, a common first ingredient in baby formula was 'corn syrup solids' or 'corn syrup'. This is simply a form of corn sugar, not unlike High Fructose Corn Syrup, except not as sweet. Common second and third ingredients are vegetable oils, corn maltodextrin (another sugar absorbed as rapidly as glucose), and sugar (sucrose, which is table sugar).

Now you tell me, do any of these things come out of a woman's breast? Do you think that this matches breast milk? Not no, but hell no. Breast milk has animal fat in it, we being animals and all. It is not soybean oil, or sunflower oil, or any other oil derived from a plant. Also, the sugar in breast milk is lactose, it is not sucrose. It is absorbed slower by the blood stream, lactose having a much lower glycemic index than sucrose (46 vs. 61). Also breast milk has more whole, saturated fat in it, which slows the absorption of lactose even more. This matters in terms of insulin resistance! These things are not the same, they are completely different.

Besides the main ingredients, infant formula also has mono- and diglycerides, a hydrogenated oil (trans fat) that is used as an emulsifier. It also has carrageenan to extend shelf life.

Mothers often have no choice but to work, and often either don't have the facilities or time at work to pump breast milk, or they don't know they ought to. They probably think formula is fine. Why is this allowed? Breast milk is best obviously, but in the case it can't be used why must we have junk food as formula?

It's ridiculous. I wouldn't be at all surprised if this is part of the reason why so many children are obese and type II diabetic.

Some examples:
Enfamil Prosobee, first ingredient Corn Syrup Solids, second ingredient is vegetable oil

Gerber good start Soy Plus, first ingredient is Corn Maltodextrin, second is vegetable oil

Similac Sensitive, first ingredient is Corn Syrup Solids, followed by sugar, as in table sugar.

And these are just a few of the ones on there. Almost all of them are the same crap.

I know that some infants are lactose intolerant or that some women don't produce enough milk. If you cannot feed your baby breast milk, I suggest looking into meat based formula. I know that's what I was fed, because I was allergic to milk and soy protein. I couldn't have regular formula or soy formula. Of course this was a long time ago, so if you found such formula now it may have crap in it too. Also, I bet regular baby formula when I was a baby did not have this crap in it.

Ridiculous. That's all I can think.

Statins: A real money maker

Since it's February and it's heart month, it's the time of year that the pharmaceutical companies start promoting you being on medication of dubious benefit with possible dangerous side effects for the rest of your life. (Statins are cholesterol lowering drugs, like Lipitor and Crestor). Do they have to pay for this advertising? Hell no. They get "journalists" to publish the advertisment-as-news-story.

The first news article I read today about the untreated "epidemic of high cholesterol" was based on a study by the World Health Organization that found that a lot of people in developing countries had high cholesterol and were therefore at risk of heart attacks. They then cited this statistic:
"Cardiovascular disease kills more than 17 million people every year and WHO says 80 percent of these deaths occur in developing countries."

To which my morbid and sarcastic mind thought, one death is a tragedy, a million is a statistic. (attributed to Stalin) So, this means that not that many people die of cardiovascular disease in the world. 17 million divided by the population of planet earth, which is about 7 billion at the moment means that .002% of people in the entire world die of cardiovascular disease every year according to the statistic given anyway. And 80% are in developing countries? What else is killing people?

Probably cancer from trying to lower our cholesterol, and in the case of developing countries, infectious disease. But if the pharmaceutical companies don't scare people into thinking there's an epidemic, no one will want to take the medication they're hawking.

Another news article was complaining about the fact that so many Americans aren't getting treated for high cholesterol.
"In all, as many as two out of three Americans with high levels of bad cholesterol do not have their problem under control, the Centers for Disease Control and Prevention said Tuesday.

That means only about 23 million of the 71 million adults with worrisome bad cholesterol levels keep it in check, perhaps because many don't eat wisely, exercise or take prescribed medications, experts said."

Never mind that diet and exercise have nothing to do with cholesterol, that it's genetic, and on top of that, has very little, if anything to do with cardiovascular disease!

What these articles are really decrying, is the fact that not *everyone* is on a statin. They want to put children on them from what I've heard. Another article says anyone over the age of 20 should have their cholesterol checked.
"There has been a national health objective known as Healthy People 2010 that seeks to make at least 80 percent of people age 20 and older aware of their cholesterol level. Unfortunately, this goal is not being met by every state in the nation."

My father-in-law is a pharmacist, and when he started out way back in the day, very few people were on maintenance medication. Those with high blood pressure and diabetes were about the only ones, and there weren't very many of them. Now he said, everyone's on maintenance medication for the rest of their lives, in an attempt to fix what our broken diet has caused. They wind up with side effects from the first medication and wind up on more medication to treat the side effects from the first!

If you're worried about cardiovascular disease, first you need to read either Gary Taubes book "Good Calories, Bad Calories" or "Why We Get Fat And What to Do About It." Then you need to read Dr. Uffe Ravnskov's books on fat and cholesterol. His first book is out of print, but his second two can be bought from Amazon. If you want more reading, check out books on homocysteine by Dr. Kilmer McCully, MD. They also have a website with information on why cholesterol is not important and why statins are dangerous to your health.

If you have family members that are on statins, they should probably wean themselves off of them. If you want to know why, read books on statin side effects and how they cause normal biological functions to cease, by Dr. Duane Graveline, MD.

**Do not go off of medication cold turkey. Consult a doctor, or better yet a pharmacist first. Pharmacists know more about medications than doctors.

Exercising your way to health or death?

Forty years ago, your parents or grandparents would have told you that exercise was bad for you. It wears out your joints and puts unnecessary strain on your body. Currently the CDC suggests 300 minutes of moderate intensity aerobic activity each week plus weight training for "greater health benefits." That's three hundred minutes of you wearing your body out every week. And if you do more than that, they say "you'll gain even more health benefits."

Now, do you think they have specific data on this? Of course not. But they'll tell you it's a good idea anyway, and in fact tout it as a way to prevent heart disease. Wait for it though, because I found this, written for heart month, from the newspaper the Asheville Citizen-Times and I found it amusing in it's glorious contradiction:
"A key contributor to heart disease is lack of exercise — again, a factor that seems to affect busy women as they juggle jobs, kids, homes and community work and fail to make time for their own good health, Palmer said. And obesity is a critical factor, because “the more you weigh, the harder your heart has to work to give your body nutrients,” she said." [emphasis mine]

So, their first premise is that if you work your heart harder (by exercise) that you'll be healthier, but if your heart has to work harder because you're overweight or obese, that's bad. Can we say cognitive dissonance? Of course, being obese is associated with heart disease, but the primary reason for CHD isn't because your heart has to work harder, it's probably inflammation. However, I doubt having your heart work harder, either via strenuous exercise or by being obese, is very good for it.

I'm not saying that some activity isn't good, especially walking, but these people are advocating that an already busy person, who is not sitting at home watching television all day, should try to fit exercising into their already busy schedule. And that just creates more stress because they think it's a character flaw that they've gained weight and blame it on not getting to the gym. I think that makes about as much sense as telling a diabetic they should eat more fruit. Oh, wait. They do that too.

I tried to find some studies to either backup what they're saying or refute it, but it doesn't seem like any have really been done, at least with exercise alone. I would imagine to find out if exercise were beneficial, that you would take two very large groups of healthy men and women and have one group exercise and the other not. Then you'd find out if one group lived longer than the other. Most of the studies I've seen however, are in patients who already have CHD, are part of Statin drug trials, or part of a diet trial. There is no controlling for variables, they test multiple things at once, and that is not science. It's quackery is what it is.

There are multiple possibilities for why exercise could be beneficial, or not. One might be if carbohydrates cause heart disease by creating inflammation, and if you consume carbohydrates and exercise, you may burn off the carbohydrates before they can have an effect on your tissues, if you're a person who can burn them off. Most people who are obese have a problem metabolizing carbohydrates, so this probably wouldn't work for them. Or maybe if you never eat carbohydrates, you would have no need to exercise very much, and you would still live just as long as someone who ate carbohydrates and exercised. These are things that could be tested.

We should know so much more by now about what it is that is killing us, but we don't, and we won't. The food industry benefits from people eating their processed, expensive junk food and the pharmaceutical companies reap the benefits of people winding up on maintenance medication from such diets. To a lesser extent the fitness industry benefits from this too, as people try in vain to exercise to lose the weight they gain (exercise makes you hungry) by eating the "recommended diet". And the newspapers? They benefit by advertising dollars from the previous three industries to push what they want to be said.

Unintended Consequences: Salt Intake, Obesity and Insulin Resistance

When William Banting wrote his Letter on Corpulence in 1863, the medical community attacked him like piranhas in a lake filled with hemophiliac swimmers. Gary Taubes describes this best in his book Good Calories, Bad Calories:
"The medical community of Banting's day didn't quite know what to make of him or his diet. Correspondents to the British Medical Journal seemed occasionally open-minded, albeit suitably skeptical; a formal paper was presented on the efficacy and safety of Banting's diet at the 1864 meeting of the British Medical Association. Others did what members of established societies often do when confronted with a radical new concept: they attacked both the message and the messenger. The editors of The Lancet, which is to the BMJ what Newsweek is to Time, were particularly ruthless. First, they insisted that Banting's diet was old news, which it was, although Banting never claimed otherwise. The medical literature, wrote The Lancet, "is tolerably complete, and supplies abundant evidence that all which Mr. Banting advises has been written over and over again." Banting responded that this might well have been so, but it was news to him and other corpulent individuals." [emphasis mine]

It was news to me as well. No one told me that I should eat that way. But what else was news to me is this, apparently restricting sodium intake can cause and/or aggravate insulin resistance. In a country with what some call a "diabetes epidemic" why are nutritionists still advocating restricting sodium intake? Especially when lower salt intake does little for lowering blood pressure, which is why it's pushed on the general public in the first place. One review found that a reduction in dietary sodium would amount to systolic blood pressure being lowered by a whopping mean of 1.1 mmHg, and diastolic by an even more underwhelming mean of 0.6 mmHg.

I suppose part of it may be because it seems a lot of the studies done were published in a journal called American Journal of Hypertension over the last 20(!) years, and I guess the "experts" and the "nutritionists" don't read it. I mean, don't read period. Because if they did, they'd have read Taubes and the plethora of other studies that would tell them that what they're telling people is flat out wrong and is killing them.

Not only can salt restriction apparently be bad for insulin resistance, but one study showed giving people more salt helps alleviate it and makes them more sensitive to the insulin.
"For the group as a whole, urinary sodium excretion increased on sodium chloride to 267 ± 118 mEq/day versus control (placebo) phase of 135 ± 53 mEq/day, P < .001. Total glycemic response in the oral GTT (area under the glucose curve) was 8.0% lower during sodium supplementation, P < .001. Secondary analysis revealed that the effect of sodium was noteworthy in 1) type 2 diabetic subjects (n = 8), 2) sodium -sensitive subjects (n = 10), and 3) nondiabetic subjects receiving antihypertensive drug treatment (n = 6). The total insulinemic response to oral GTT was also lowered by sodium loading among diabetic subjects. Thus, an abundant sodium intake may improve glucose tolerance and insulin resistance, especially in diabetic, salt-sensitive, and or medicated essential hypertensive subjects." [emphasis mine]

(The effect of sodium supplementation on glucose tolerance and insulin concentrations in patients with hypertension and diabetes mellitus, from the American Journal of Hypertension, Volume 14, Issue 7, July 2001, Pages 653-659)

One of the most recent and largest studies from the journal Metabolism, took data from 152 healthy people who were prescribed a high or low salt diet. It too found that a low salt diet was associated with increased insulin resistance.

People are expensive to do studies on. You have to pay them to participate. Lab rats on the other hand are cheap and you don't have to pay them anything and you get to dissect them when the study is over so you can obtain even more information on what was going on physiologically. One rat study found:
"In the present study, higher body weight, blood glucose, plasma insulin, triacylglycerols (triglycerides) and cholesterol, hematocrit and heart rate were observed in animals on low salt intake compared to the normal-salt group. Blood pressure and glucose uptake were lower on low-than on normal-salt diet." [emphasis mine]

(Insulin resistance due to chronic salt restriction is corrected by α and β blockade and by l-arginine, from Physiology & Behavior, Volume 88, Issues 4-5, 30 July 2006, Pages 364-370)


If you've been paying attention, insulin resistance (and by extension diabetes) is associated with obesity. Apparently one study showed that restricting salt intake in female Wistar rats predisposed their female offspring to obesity.

Most of the studies say that more and larger studies are needed. As mentioned above, studies are expensive. There were some studies in humans that found the opposite or no correlation between salt intake and insulin resistance, but of these I saw, they used a very small number of people, in one only eight and were very short term. That's not enough subjects or time to get meaningful data. We need large studies with lots of people, that way individual variation is controlled for. All of the rat studies I found showed a correlation with low salt intake and insulin resistance, and since rats are cheap, there were more rats involved than people. It may be that some people are not as effected by low sodium intake as others.

So here we have unintended consequences, in that nutritionists are advocating you messing with your diet for what might amount to a slightly lower blood pressure, at the expense of something else completely unforeseen. How do you like being an unwitting participant in one of the biggest health studies ever made? Because that's what you are if you live in any country that follows the dietary guidelines set forth by the USDA. You may think you have no problem eating as you are, but the food manufacturers have made it a point to remove salt and fat from the food they sell you. So unless you are making a concerted effort to add it back in, you may well be deficient and not even know it.

Common sense is indeed not very common. If excess salt intake had anything to do with ill health, the human race in western Europe and elsewhere would not have survived into the modern era. Last I checked, prior to the 20th century, people did not have refrigeration and used, get this, salt and LOTS of it to cure meat. I doubt there's any way to find out exactly how much they consumed, but it was way more than we do now. And since we don't have reports that medieval people were dropping dead from stroke or heart disease (plague is another matter), I dare say the salt wasn't a primary cause of mortality. Of course, absense of evidence is not evidence of absence, and maybe they just didn't live long enough for the salt to kill them.
