Is Getting Your Cholesterol Tested Even Necessary?


See below for an article by Dr. Natasha Campbell-McBride on cholesterol testing and the negatives of doing it. Enjoy :)

Many people ask me this question:

WHEN I TEST MY BLOOD CHOLESTEROL, WHAT SHOULD IT BE?

My answer is:

DON'T TEST YOUR BLOOD CHOLESTEROL!

IT IS A POINTLESS EXERCISE AND A POTENTIALLY HARMFUL ONE!

I will explain, why.

Your blood levels of cholesterol are maintained by your liver: when we eat more cholesterol, the liver produces less; when we eat less cholesterol - the liver produces more. That is why low-fat and cholesterol-free diets have no effect on blood cholesterol: your liver will maintain a particular amount of cholesterol in your blood, depending on what your body is doing at the time.

Why does your body need cholesterol?
Our bodies are made out of cholesterol and fats to quite a large degree, and cholesterol is essential for many functions. Cholesterol is such an essential part of our human physiology that the body has very efficient mechanisms to keep blood cholesterol at a certain level at any given moment of your life. However, cholesterol - lowering drugs (statins) are a completely different matter! They interfere with the body's ability to produce cholesterol and hence they do reduce the amount of cholesterol available for the body to use. Let us see just how dangerous that is.

Human brain is hungry for cholesterol!
Every structure in the brain needs cholesterol and saturated fats not only to build itself but also to accomplish its many functions. If you start interfering with the body's ability to produce cholesterol you put the very structure of the brain and the rest of the nervous system under threat. Memory loss and cognitive decline are very common results of statin therapy. In fact it is possible that a considerable part of dementia epidemic in our ageing population is due to our ubiquitous statin prescriptions. Eating fresh eggs and butter daily has been shown to improve memory and cognitive ability in the elderly. Any person with memory loss or learning problems needs to have plenty of these foods every single day in order to recover.

More recently statins have been linked to development of Parkinson's disease. The leading researcher Dr Xuemei Huang from North Carolina University stated: "A surge in Parkinson's disease could be imminent because of the widespread use of statins."

There are people whose bodies are unable to produce enough cholesterol; these people do need to have plenty of foods rich in cholesterol in order to provide their organs with this essential-to-life substance. Low blood cholesterol has been routinely recorded in criminals who committed murder and other violent crimes, people with aggressive and violent personalities, people prone to suicide and people with aggressive social behaviour and low self-control. From the beginning of cholesterol-lowering drug trials increased numbers of deaths from violence and suicide have been recorded. The late Oxford Professor David Horrobin warned us: "reducing cholesterol in the population on a large scale could lead to a general shift to more violent patterns of behaviour. Most of this increased violence would not result in death but in more aggression at work and in the family, more child abuse, more wife-beating and generally more unhappiness." Indeed, one of the fist side effects of statins is the change in mood and personality towards being intolerant, aggressive and short-tempered - a warning sign that the brain is starving for cholesterol.

Cholesterol protects us from infections!
Cholesterol is essential for our immune system to function properly. People with low blood cholesterol are more prone to infections and when they get an infection they are more likely to die from it, compared to people with high cholesterol. Before the discovery of antibiotics mixture of raw egg yolks and cream, very rich in cholesterol, was used as a cure for tuberculosis and other infections for centuries.

Every steroid hormone in the body is made out of cholesterol!
After the brain, the organs which are very hungry for cholesterol are our endocrine glands: adrenals and sex glands. They produce steroid hormones, which accomplish a myriad of functions in the body. Without cholesterol we will not be able to cope with stress or to have children.

Cholesterol is essential for babies and children!
The proponents of the diet-heart hypothesis and the public policy makers tell us that our children from the age of two should follow a programme for reducing their blood cholesterol by avoiding natural fats and replacing them with margarine. The pharmaceutical giants are working hard on creating cholesterol-lowering drugs for children. These dangerous guidelines are given out "just in case", without any scientific data to support them. The consequences of this policy can be very serious indeed for our children: aggressive behaviour, learning difficulties, poor memory, poor immunity, poor physical health combined with the future risk of developing cancer, heart disease, stroke and infertility. Children's bodies are generally not able to produce enough cholesterol for growth and development, so eating cholesterol-rich foods is essential for children! That is why human breast milk is very rich in cholesterol!

Cholesterol is essential for the elderly!
Many studies have shown that old people with high cholesterol are healthier and live longer than people with low cholesterol. In fact it is dangerous to reduce cholesterol in old people. And yet that is exactly what our doctors are doing! The older the person is the more their low blood cholesterol poses a risk of stroke, while it has been clearly demonstrated that high blood cholesterol protects older people from strokes, heart disease, infections, cancer and many other health problems.

Vitamin D is made out of cholesterol in the body!
Our recent misguided fear of sun and avoidance of cholesterol have created an epidemic of vitamin D deficiency in the Western world leading to cancer, diabetes, heart disease, mental illness, autoimmune illness, obesity, bone and muscle disease, high blood pressure, chronic pain, poor immunity and susceptibility to infections. As many people are unable to produce enough of their own cholesterol, eating cholesterol-rich foods is essential for them to produce vitamin D.

Cholesterol and saturated fats are essential for healing!
No damage in the body, no wound or scratch can be healed without cholesterol and saturated fats. That is why large-scale studies have found that people who have low levels of cholesterol are prone to cancer, because their bodies cannot heal damaged tissues.

It is this function of healing that brings us back to the testing for cholesterol: all your blood level reflects is how much damage there is in your body at any particular moment, that has to be healed. If you had a cold, an infection, a dental treatment or a surgical procedure, then there is a lot of damage in your body to heal, so your blood cholesterol level will be high until the healing has taken place. If you are tired and under stress, your adrenals have a high demand for cholesterol, as they make their hormones from it. So, your liver has to produce more cholesterol than usual and send it to your adrenals, making blood levels of cholesterol high. In winter cholesterol goes high and in the summer it is generally lower, because cold weather and lack of the sunshine vitamin D places high demands on your immune system, which is very hungry for cholesterol. These are just a few scenarios when your blood cholesterol has to be high to serve your body's needs.

Every day, depending on what your body is doing, your blood cholesterol levels go up and down quite a lot. A blood test for cholesterol will give you a snippet of this activity, completely out of context of your body's needs at the time. If this snippet happens to find it high, then two harmful things can happen to you:

1. You are likely to be put under pressure to start a statin therapy, depriving your body from one of the most essential nutrients;
2. You will have to live with a new anxiety - a fear of heart disease! And for no good reason at all, because cholesterol levels in your blood have nothing to do with heart disease.

If you really want to know about your risk of heart disease, then these are the tests to do:
1. C-reactive protein, which is a marker for inflammation in the body. Heart disease is an inflammatory condition.
2. Insulin levels in your blood. The insulin profile will show if you suffer from a metabolic syndrome, which is the underlying condition for heart disease.

Is Cholesterol Really Killing You?

Lets put an end to the whole cholesterol debate and find out what's really going on.

My friend and colleague, Vreni Gurd, BHK, CHEK 3, shares what HDL and LDL cholesterol is and what the real culprits are in heart disease and clogging of the arteries.

HDL and LDL - good and bad "cholesterol"?

High Density Lipoproteins (HDL) and Low Density Lipoproteins (LDL) are PROTEINS, not forms of cholesterol, contrary to popular belief. Cholesterol is cholesterol. There are NOT different forms of the cholesterol molecule.

Is it logical to think that our bodies would manufacture a substance in order to give us a disease? Of course not. Yet many of us are worried about our cholesterol levels, something our body manufactures regularly. Cholesterol is a waxy substance that is the precursor to many of our hormones, including testosterone, estrogen, progesterone, cortisol, pregnenalone and DHEA. Cholesterol is an antioxidant, sopping up free radicals, and is also a very important part of cell membranes, so as our cells die (blood cells, skin cells, bone cells, muscle cells etc.), cholesterol is needed to make the membranes of the replacement cells. Considering we replace about 2 million blood cells each second, it becomes obvious that cholesterol is vitally important, and we would not survive without it. If tissue is damaged, more cholesterol is needed to repair and replace the damaged cells with healthy ones. No wonder it is so important that our liver can easily manufacture cholesterol.

So, if LDL and HDL are not cholesterol, what are they? They are proteins that act as transportation vehicles that carry the cholesterol to the various locations in the body, just like a bus carries people to wherever they want to go. Cholesterol is fatty, and needs to travel in a watery medium (blood), so protein carriers are necessary to make the cholesterol water soluble. The passenger is the same (cholesterol), but the bus (protein) is different, depending on the direction the cholesterol is traveling. Would we call Harry and John "bad people" when they happened to be traveling in a mini-van shuttle, and "good people" when they happened to be traveling on a large bus? The idea is absurd. Yet, this is what we do to cholesterol. LDL proteins (so called "bad cholesterol") carry the cholesterol from the liver out to the tissues, and HDL proteins (so called "good cholesterol") carry the cholesterol from the tissues back to the liver. Contrary to popular belief, HDL proteins do not rid the body of the cholesterol at all - they simply return it to the liver for recycling, so it can make its next trip out on the LDL bus.

The difference between High Density Lipoproteins (HDL) and Low Density Lipoproteins (LDL) is the size and density of the molecule, with HDL molecules being larger. The smaller the molecule, the more likely it will get stuck or caught in the gap junctions between arterial cells etc., where they then oxidize, causing inflammation, which begins the artery-narrowing process. Our bodies also make VLDL (Very Low Density Lipoproteins) which also carry cholesterol but in lesser amounts per molecule due to the much much smaller size, and these molecules are far more likely to get caught along the walls of the arteries than LDL. If the LDL molecules are of normal size, they don't get stuck. They just do their job as they should. People are rarely tested for their VLDL levels, yet this along with triglyceride levels are much more predictive of cardiovascular disease than total cholesterol. So, it is not the cholesterol that is the problem, but the size of the protein carrier.

Can you do anything to control the size of the protein carrier? Yes. Diet is very important. And do you think it is lowering saturated fat and cholesterol intake that will make the difference? No. As it turns out, the higher the easily digestible carbohydrate intake (sugar, flour, processed grains - no, rice cakes are NOT healthy!), the more the VLDL proteins made (the smaller ones that are more likely to get stuck) which greatly increase one's risk of cardiovascular disease. Sugar and flour products also increase glycation and Advanced Glycation Endproducts (AGEs), which causes arterial inflammation, also known to increase cardiovascular disease risk, and sugar and flour increase insulin secretion, which increases sympathetic load, increasing blood pressure, another risk factor for heart disease. There is simply nothing healthy at all about quickly digested carbohydrates like processed sugar, flour and processed grains (puffed wheat etc.), and until we stop eating them, the scourge of modern degenerative diseases won't abate.
