Cholesterol is Essential for Cellular Function
What this tells us is that cholesterol deficiency impacts virtually every aspect of your health. One of the primary reasons for this widespread effect is because cholesterol plays a critical role within your cell membranes. Your body is composed of trillions of cells that need to interact with each other. Cholesterol is one of the molecules that allow for these interactions to take place. For example, cholesterol is the precursor to bile acids, so without sufficient amounts of cholesterol, your digestive system can be adversely affected.
It also plays an essential role in your brain, which contains about 25 percent of the cholesterol in your body. It is critical for synapse formation, i.e. the connections between your neurons, which allow you to think, learn new things, and form memories. In fact, there's reason to believe that low-fat diets and/or cholesterol-lowering drugs may cause or contribute to Alzheimer's disease3. Low cholesterol levels have also been linked to violent behavior, due to adverse changes in brain chemistry.
Furthermore, you need cholesterol to produce steroid hormones, including your sex hormones. Vitamin D is also synthesized from a close relative of cholesterol: 7-dehydrocholesterol.
To further reinforce the importance of cholesterol, I want to remind you of the work of Dr. Stephanie Seneff, who also works with the Weston A. Price Foundation. One of her theories is that cholesterol combines with sulfur to form cholesterol sulfate, and that this cholesterol sulfate helps thin your blood by serving as a reservoir for the electron donations you receive when walking barefoot on the earth (also called grounding). She believes that, via this blood-thinning mechanism, cholesterol sulfate may provide natural protection against heart disease. In fact, she goes so far as to hypothesize that heart disease is likely the result ofcholesterol deficiency — which of course is the complete opposite of the conventional view.
Identifying Risk Factors for Heart Disease
Heart disease is clearly one of the leading causes of death in the US, making it imperative for the vast majority of people to understand the risk factors in order to avoid becoming a statistic. However, total cholesterol will tell you virtually nothing about your disease risk, unless it's exceptionally elevated (above 330 or so, which would be suggestive of familial hypercholesterolemia, which, in my view, would be about the only time a cholesterol-reducing drug would be appropriate).
Two ratios that are far better indicators of heart disease risk are:
- Your HDL/total cholesterol ratio: HDL percentage is a very potent heart disease risk factor. Just divide your HDL level by your total cholesterol. This percentage should ideally be above 24 percent. Below 10 percent, it's a significant indicator of risk for heart disease
- Your triglyceride/HDL ratios: This percentage should ideally be below 2
Four additional risk factors for heart disease are:
- Your fasting insulin level: Any meal or snack high in carbohydrates like fructose and refined grains generates a rapid rise in blood glucose and then insulin to compensate for the rise in blood sugar. The insulin released from eating too many carbs promotes fat and makes it more difficult for your body to shed excess weight, and excess fat, particularly around your belly, is one of the major contributors to heart disease
- Your fasting blood sugar level: Studies have shown that people with a fasting blood sugar level of 100-125 mg/dl had a nearly 300 percent increase higher risk of having coronary heart disease than people with a level below 79 mg/dl
- Your waist circumference: Visceral fat, the type of fat that collects around your internal organs, is a well-recognized risk factor for heart disease. The simplest way to evaluate your risk here is by simply measuring your waist circumference. For further instructions, please see my previous article, Your Waist Size Can Be a Powerful Predictor of Hypertension and Other Chronic Diseases
- Your iron level: Iron can be a very potent oxidative stress, so if you have excess iron levels you can damage your blood vessels and increase your risk of heart disease. Ideally, you should monitor your ferritin levels and make sure they are not much above 80 ng/ml. The simplest way to lower them if they are elevated is to donate your blood. If that is not possible you can have a therapeutic phlebotomy and that will effectively eliminate the excess iron from your body
