Please pardon the harsh language, but I need to say this plainly and strongly.

EVERYTHING YOU KNOW ABOUT CHOLESTEROL IS BULL$HIT

Here’s a little crash course on cholesterol and heart disease. We know that most of the time atherosclerosis and heart disease patients usually have elevated levels of cholesterol in their blood. We also know that many of these patients have deposits of the goopy fatty stuff crusting on the insides of their blood vessels. These things are correlated, which means they are usually found together. That part is true. The conclusion that was made was that the dietary fat and serum cholesterol levels of these patients was the direct cause of the hardening of the blood vessels, the clogs and the heart attacks. That part is suspect, and the topic of this article.

That is certainly a possibility, but there are other ways to perceive this correlation. One popular theory is that other forces acting on your blood vessels cause damage and thinning. Different theories attribute this damage to anything from pH levels, to a lack of vitamin-C in the diet, to any number of other dietary and lifestyle factors. When this damage occurs in the artery walls your body directs cholesterol to the site and clumps it up to harden and support and patch the thin or damaged areas. This is only supposed to be a temporary fix, and if the conditions that caused the damage continue then the “patches” will continue to accumulate until they form serious clogs and cause heart attack or a stroke, among other things.

Assuming that the presence of a large amount of cholesterol in the blood is a cause is kind of like assuming that because you always see firemen at burning buildings that they must have set the fires. That’s not to say that high cholesterol is something to ignore. It can be a warning sign of some condition that has caused the need for those artery “patches” I mentioned. Then again it also can mean nothing at all. Some people have what is known as “familial hypercholesterolemia.” That’s just a fancy way of saying that they are genetically programmed to have high levels of blood cholesterol. Many people with this genetic predisposition lead happy and healthy lives without ever developing heart disease.

But let’s take one more look at that original theory about the dietary fat and cholesterol clogging up the arteries and being the cause of the problem. Ask any plumber and they will tell you that this doesn’t make sense. We can all agree that in the body it’s the largest blood vessels that run directly in and out of the heart that get all this clogging and hardening action. In terms of clogged plumbing, the smaller blood vessels would be the biggest problems first. They would clog up badly and way before the larger arteries were even a noticeable problem yet. But that isn’t what the findings show. The findings suggest that the clogging is directed and targeted in those large blood vessels, and if that’s the case, then the body is doing it itself, as suggested above. That would make the clogging not a cause, but a symptom of a larger problem.

I don’t mean to leave this topic on a down note, but make sure that you are assessing other risk factors when evaluating high cholesterol. Watch out for other factors that can create a problem such as a family history of heart disease, poor diet, smoking, sedentary lifestyle, high stress, etc. Be smart and work with a physician before making any decisions.

For more information (and a LOT of it) you can read more at THINCS (The International Network of Cholesterol Skeptics). It’s members include scientists from all over the world, including several nobel laureates. Some of them may disagree on what does cause heart disease, but they all agree that cholesterol does not.

China Study: A Closer Look

When I first heard about THE CHINA STUDY, and then later thumbed through the copy my girlfriend brought home from the library, I was immediately both interested and skeptical. As a fitness professional I am always interested in new food research, but I am also immediately skeptical of any conclusions until I see the data for myself. When the book first landed in my lap I opened to a random spot somewhere in the middle and found examples of bad scientific method straight away without even trying.

What struck me about Campbell’s conclusions from those first few pages was that he was disregarding way too many variables in his quest to support his points. He would describe the specific population, and ailment in a given section of the study and lay out some interesting numbers and then proceed to make astounding  leaps of logic that left me shaking my head, and saying “tsk tsk tsk.”

I don’t have the time or inclination to write a point-by-point breakdown of all the flaws in The China Study, but thankfully  RAW FOOD SOS does just that for us. What I love about her arguments is she backs them up with the actual numbers that Campbell used, she just approaches them with a sharper intellect. And did I mention the author, Denise minger, is a raw-foodie herself?

And before anyone gets angry with me (or Ms. Minger for that matter) for attacking The China Study, understand that we both already eat a heavily plant-based diet ourselves. I myself avoid dairy almost entirely, and eat meat products only a few times a week. Before finding the omnivorous equilibrium I have now I spent five years as a vegetarian, and then another five years eating large amounts of animal products. I won’t speak further for the author, but I have discovered that with regard to eating, like with most things in life, the middle of the road is the best way to go.

I want to be clear that there are elements of the book I appreciated as well. He does lay out several things that most people don’t know and should. He also does draw some compelling conclusions here and there. But, in the name of good science, and good analysis, I cannot let the book stand as gospel as so many people do. It has issues, and most of those issues stem from a misleading representation of the statistics, and Ms. Minger’s website does a good job of illustrating these issues in a clear and concise manner.

Sleep

sleep

Those of my readers that know me well also know that I have struggled with sleep disorder my entire life. Among my earliest memories of life are tantrums thrown in the wee small hours of the night because I couldn’t fall asleep, and my six-year-old brain couldn’t understand why. I spent most of my high school and college years averaging anywhere from 3 to 12 hours per night. My sleep habits were erratic, and sloppy and I suffered a great many stressful nights of tossing and turning because of it.

in 2007 I discovered a great book called POWER SLEEP. In it I found several great strategies that help, and explanations as to why they will help, in case you’re curious about that too. It’s based on two generations of sleep research, and it covers a wide-variety of issues, from sleep-deprived new parents, to office workers getting drowsy at their desks. Nearly everyone can find something of value in this book.

The simplest and most helpful tip I can share with you right now is this: make it dark. The space you sleep in needs to be as close to pitch black as possible. No LCD display alarm clock, no streetlights streaming in. Complete. Total. Darkness. This goes back to our evolutionary roots. Sleep habits in mammals, including our own, likely developed in the first land mammals who burrowed into the earth, or slept in dark caves. Keep in mind that predating electric lighting, finding complete darkenss to sleep in was never a problem. Now you’ve got to rid your bedroom of all light, and the easiest way is some dark, heavy curtains.
Today I found a great article on MARK’S DAILY APPLE all about the impact of SLEEP POSTURE. He posits, and I agree, that your sleep posture has a greater impact on your quality of sleep than even does your bedding and mattress. Afterall, why else are you tossing and turning? You’re trying to find that “sweet spot,” that lying posture that lets you fully relax and drift off. He gives you a specific way of lying down that can help you find it. Check it out.
