HIGH CHOLESTEROL

Controlling high cholesterol can be a challenge, but with the right nutritional supplements many people have success...

Despite the hype, cholesterol is actually not all bad; it is the amount and the ratio of the certain forms of cholesterol that are a health concern. Low-density lipoprotein (LDL cholesterol) is commonly called “bad” cholesterol, while high-density lipoprotein (HDL cholesterol) is commonly referred to as “good” cholesterol. Interestingly, it is not the type of cholesterol that is important, so much as the balance of “good” vs. “bad”.

Cholesterol is an essential molecule in our bodies. Our body cells use cholesterol to support their cell membranes and some of the membrane-associated receptor molecules. Cholesterol is also used to make steroid hormones in the body. Some examples of steroid hormones are reproductive hormones such as estrogen, progesterone, testosterone, and the stress hormone cortisol. Because of this, it is essential to keep cholesterol in balance in the body.

Blood Cycle

Cholesterol cycles from the liver to the body cells, and back again, via the blood. LDL cholesterol consists of fats that are being transported from the liver for use by your cells. HDL cholesterol consists of fat that is taking unused (excess) cholesterol from your cells back to the liver, where it is excreted. Because of this, high levels of LDL are not a big concern, so long as there are sufficient levels of HDL to retrieve any excess cholesterol left behind in the body. Thus, cholesterol levels are unhealthy if you have excess circulating LDL, insufficient HDL, or a combination of the two. Cholesterol that is left in the rest of the body and not retrieved by sufficient HDL can build up inside the arteries and when combined with systemic inflammation, can cause cardiovascular disease. Thus, maintaining cholesterol balance, or a good cholesterol ratio on your blood work is actually more important than targeting LDL cholesterol directly. Supplementing fish oil is an excellent way to boost your HDL cholesterol. For more information, please see our Fish Oil article.

Cardiovascular Disease

High cholesterol contributes to cardiovascular disease, also known as heart disease, which is the number one cause of death in North Americans. High cholesterol causes a buildup of molecules inside of arteries that narrows the arteries and erases the elasticity and flexibility of the artery walls. The body responds to this narrowed space by increasing blood pressure to ensure adequate blood flow to all tissues. This is referred to as high blood pressure. When pieces of the cholesterol plaque break off, they can cause a change in the blood flow which leads to clots; clots and cholesterol plaque can and do end up causing heart attacks and strokes. For more information, please see our Cardiovascular Health article.

Cholesterol Cycle

Interestingly, the liver not only synthesizes cholesterol, it is also responsible for excreting any excess. It does this by mixing it in with the bile, and releasing it into the digestive tract. This cholesterol in the gut gets mixed with any food and is bound by any soluble fibre present. For more information on its cholesterol-binding capability, please see our Fiber article. Once it is bound, the cholesterol is shed with the stool. Unfortunately, any unbound cholesterol in the gut is free to be reabsorbed by the body and to again cycle in the bloodstream.

BALANCING BLOOD CHOLESTEROL

Lifestyle Changes

Lifestyle factors such as smoking, obesity, improper diet, stress and lack of exercise contribute to your risk of developing high cholesterol and heart disease by causing inflammation and increasing the burden on your liver.

It is encouraging to note that adopting a healthier lifestyle and using natural therapies can maintain a healthy vascular system.

Conventional treatment

Standard treatment of high cholesterol with lipid-lowering drugs decreases serum cholesterol but makes only small improvements to your chances of developing heart disease. This may be due to the role of systemic inflammation in arteriosclerosis.

Also, these drugs have many side effects. The most troublesome is the increased risk of depression and suicide amongst medicated individuals. The drugs also deplete vital nutrients for heart health such as coenzyme Q10. For more information, please see our coenzyme Q10 article. These medications can interact with natural products. Consult a health professional before starting any new therapy.

Dietary Changes

There are a number of dietary changes that can be used for high cholesterol. These include maintaining adequate fiber intake and lowering the fat and cholesterol content of your foods. Be sure to drink lots of clear fluids and eat raw fruits, vegetables, and whole grains. Include green leafy vegetables, nuts, and seeds. Try to focus on vegetable proteins like legumes and soybeans. Also try to preferentially use unrefined oils like olive, flax, and sunflower in your daily diet. Foods to avoid are any kinds of margarine, hydrogenated oils, junk foods, fried foods, processed foods, fast foods, white flour products, white sugar products, red meat, ice cream, salt, coffee, colas and other caffeine sources. Eliminate alcohol, tobacco and highly spiced foods to help reduce your systemic inflammation. Use diet, exercise, and supplements to maintain a healthy weight.

Limits of Dietary Changes

Dietary cholesterol is different than the serum (blood) cholesterol mentioned above. Eating foods that are high in cholesterol can raise serum cholesterol levels, but the liver is responsible for synthesizing cholesterol as the body requires. This is the way in which genetics plays a role in high cholesterol. Thus, a cholesterol reduction plan should include a low cholesterol diet with other treatments to help to reduce serum cholesterol by treating the liver. For more information, please see our Liver Support article.

Stress Reduction

Stress reduction techniques such as deep breathing, yoga or biofeedback will help to maintain a healthy stress level. Reducing stress can help to reduce systemic inflammation, and thus help to reduce the risk of cardiovascular disease. For more information, please see our Stress article.
