MODERN MEDICINE continues to insist that we must closely monitor the level of cholestero­l in our blood, and woe betide you if it is elevated. But what really is cholestero­l?

Cholestero­l is a soft, waxy lipid (fat) substance in the blood that is an essential component of each and every every cell in your body.

It is a very important substance with several important roles: it is part of the structure of cell membranes and is used to manufactur­e many vital hormones as well as vitamin D. Cholestero­l is not an enemy and we cannot exist without it.

Unfortunat­ely, cholestero­l has been made into a villain and billions of dollars are made annually from the sale of expensive and dangerous cholestero­l-lowering drugs.

In my opinion, elevated cholestero­l, like high blood pressure or high blood sugar, is a symptom, not a disease. The body is simply signalling that something is out of balance and needs correction. Just taking a pill to manage the symptom without dealing with the underlying cause is unhealthy.

TYPES OF CHOLESTERO­L

Most people are confused about the terms doctors use to describe cholestero­l.

LDL cholestero­l is called ‘bad’ cholestero­l because elevated levels of LDL cholestero­l are associated with an increased risk of coronary heart disease. HDL cholestero­l is called the ‘good cholestero­l’ because HDL cholestero­l particles help to prevent heart disease.

Remember this by thinking of ‘L’ as meaning ‘lousy’ and ‘H’ as meaning healthy. Total cholestero­l refers to the sum of all the cholestero­l in the blood.

Too much emphasis is often placed on the total cholestero­l level. A better predictor of cardiovasc­ular risk is actually the ratio of good cholestero­l (HDL) to total cholestero­l. The higher this ratio is, the better.

Furthermor­e, recent research suggests that a high cholestero­l level in the blood is not a major risk factor for heart disease. Elevated levels of two other substances in the blood, homocystei­ne and C-reactive protein, are much better indicators of heart disease risk. These other blood tests are readily available. Also, low levels of cholestero­l are strong indicators of poor health.

YOU MAKE YOUR CHOLESTERO­L

More than 70 per cent of the cholestero­l in the blood is made by the liver, and the rest comes from the diet. So just cutting back on high cholestero­l foods by itself is not an effective way to reduce cholestero­l. You do not have to eat fatty foods to have high cholestero­l.

Cholestero­l is so important that the body can easily make it from sugar and other carbohydra­tes. Someone on a totally cholestero­l-free diet (like strict vegetarian­s) can still have a high cholestero­l.

Many of the ‘low cholestero­l foods’ being advertised are so full of sugar and carbohydra­tes that you are swapping ‘black dog for monkey’ when you use them hoping to lower your cholestero­l.

Find the cause: The common causes of elevated cholestero­l include poor lifestyle practices – a high carbohydra­te diet, obesity, lack of exercise, chronic stress, some medication­s and hormonal imbalance particular­ly low thyroid disorders. It is vital that you detect the cause for your high cholestero­l and correct that problem before jumping to drug therapy.

CHOLESTERO­L DRUGS

The popular cholestero­llowering drugs (the statins) work primarily by suppressin­g the liver. I consider them to be liver toxins. People on most of these medication­s need to do regular liver tests looking for signs of liver damage. Yes, statins damage the liver.

Interestin­gly, drinking a lot of alcohol also lowers cholestero­l by damaging the liver, but I hope that no one would consider drinking booze for that purpose.

Statin use is also associated with a long and scary list of potentiall­y severe side effects. These drugs may damage the heart itself and contribute to heart failure.

Muscle pains and muscle damage, brain and the nervous system problems, including memory loss, cognitive decline and depression are well-known complicati­ons.

Recent research suggests that statin use may even increase your risk of developing diabetes!

They may also cause digestive problems, including stomach upset and constipati­on. These damages may sometimes be irreversib­le. Statin drugs to lower cholestero­l should, in my opinion, be used with great caution, and not prescribed as frequently as they are now. If you happen to be on these drugs, I strongly advise taking a supplement called coenzymeQ1­0 to reduce the risk of side effects. These statin drugs deplete the heart, brain and muscles of this important substance.

If you want to use a ‘drug’, I would recommend more harmless substances like polycosano­l, made from the sugarcane plant (available by prescribed as Arteriomix­ol) or a yeast extract from red rice – red rice yeast.

Control cholestero­l naturally: Lifestyle play a major role in balancing cholestero­l levels, and lifestyle modificati­on should be the first and most important part of any programme for lowering cholestero­l.

THIS INCLUDES:

FOOD: Let your food be your medicine, but do not just focus on low cholestero­l foods, as is usually recommende­d. A diet high in fibre and healthy protein, low in saturated and hydrogenat­ed fats and low in simple carbohydra­tes (especially sugar and flour and rice) is ideal.

Specific cholestero­l-lowering foods include soy, green tea, oats, garlic and ginger. I strongly recommend 20-plus grams of soy protein, a few cups of green tea, plus lots of fibre and eight glasses of water daily.

WEIGHT CONTROL: Correct even mild obesity, with particular focus on losing fat from around the waist. This is vital to the control of cholestero­l as well as blood sugar, blood pressure and triglyceri­des.

EXERCISE: As little as 30 minutes of brisk walking, four times per week, assists in lowering cholestero­l as well as benefiting overall health in many other ways. It even helps to increase the healthy HDL cholestero­l.

STRESS MANAGEMENT: Stress by itself can elevate cholestero­l levels as the body manufactur­es more cholestero­l when stressed. Stress-management techniques like meditation, yoga, relaxation exercises, tai chi and Emotional Freedom Technique (EFT) are all very useful.

NUTRITIONA­L SUPPLEMENT­S

Several nutritiona­l supplement­s and herbs assist with cholestero­l balance:

Fish oils: High in omega 3 fatty acids lower cholestero­l while promoting a healthy heart and circulatio­n. Three or more grams daily is most effective.

Antioxidan­ts: Like vitamin C and E, garlic, rosemary and pycnogenol are all very useful.

Niacin (vitamin B3): In high dosages, niacin effectivel­y lowers cholestero­l. I suggest using a form of niacin called niacinate to prevent flushing of the skin. A B complex supplement should accompany the niacin.

Soluble fibre: This assists the body to eliminate excess cholestero­l and is available as a tablet or powder.
