Debunking The Cholesterol Myth

DSCN0309

If you buy any grapefruit juice this year, make sure it the "FAT-FREE" kind! I'm so happy to finally find a juice company that is trimming the fat off of their fruit. If I
were you, I would go to my refrigerator right now and check the fat content of all my juices. Caution: you have now entered the world of the absurd.

We now live in a world that is obsessed with all things that are low-fat and low-cholesterol. It is just an accepted fact that eating a low-fat diet will aid in lowering your cholesterol. Lowering your cholesterol will lead to a lower chance of heart disease and death. If this is true, why do Eskimos who eat a traditional diet of almost pure saturated fat (whale and seal blubber) have almost a zero incidence of heart disease?

Studies of African tribes have shown that intakes of enormous amounts of animal fat do not necessarily raises blood cholesterol; on the contrary it may be very low. Samburu people, for instance, eat about a pound of meat and drink almost two gallons of raw milk each day during most of the year. Milk from the African Zebu cattle is much fatter than cow's milk, which means that the Samburus consume more than twice the amount of animal fat than the average American, and yet their cholesterol is much lower, about 170 mg/dl.

Shepherds in Somalia eat almost nothing but milk from their camels. About a gallon and a half a day is normal, which amounts to almost one pound of butter fat, because camel's milk is much fatter than cow's milk. But although more than sixty percent of their energy consumption comes from animal fat, their mean cholesterol is only about 150 mg/dl, far lower than in most Western people.

The Japanese are known for their healthy diet and low cholesterol. Harvard Medical School did a study of Americans and Japanese health in the 1950's. They found that U.S. people on average had a blood cholesterol of 220 whereas Japanese had about 170. The theory has always been that people with high cholesterol were more likely to get a condition called atherosclerosis. This is usually referred to as hardening of the arteries due to plaque build up, calcification and deposits of cholesterol.

The aorta, the main artery of the body, from 659 American and 260 Japanese people were studied after death. Meticulously all signs of atherosclerosis were recorded and graded. As expected, atherosclerosis increased from age 40 and upwards, both in Americans and in Japanese. Now to the surprising fact.

When degree of atherosclerosis was compared in each age group there was hardly any difference between American and Japanese people. Between age forty and sixty Americans were a little more arteriosclerotic than Japanese; between sixty and eighty there was practically no difference, and above eighty Japanese were a little more arteriosclerotic than Americans.

A similar study was conducted by Dr J.A. Resch from Minneapolis and Dr.s N. Okabe and K. Kimoto from Kyushu, Japan. They studied the arteries of the brain in 1408 Japanese and in more than 5000 American people and found that in all age groups Japanese people were more arteriosclerotic than were Americans.

The conclusion from these studies is of course that the level of cholesterol in the blood has little importance for the development of atherosclerosis, if any at all.

Could it be that we are looking at the wrong things? Could it be that heart disease is not a disease of cholesterol at all? Could it be that eating fat has little to do with it? Look at the people on the Atkins diet as they eat foods that are full of cholesterol and fat. You might think that this would make their cholesterol (LDL) go up. The fact is that it goes down.

You might argue that vegetarians usually have lower cholesterol than other people and they eat little animal fat. But vegetarians differ from the rest of the human population in more than their diet. They usually smoke less, they are usually thinner, and they usually exercise more often than other people. Whether it is their diet, or their other living habits, or perhaps something else that lowers their blood cholesterol is unknown.

In an article by Dr. Cranton, he suggests that heart disease could be strongly linked to vitamin D3 deficiency. Robert Scragg, Associate Professor in Epidemiology at the University of Auckland, New Zealand, first proposed that vitamin D deficiency plays a role in cardiovascular disease. He explains that heart disease is higher at higher latitudes with less sunlight, lower altitudes, in the winter, in African Americans, in older, inactive, and in more obese patients. Vitamin D is the sunshine vitamin in that our body produces it naturally when our skin is exposed to the sun. Altitude is the least known of these associations. The age adjusted mortality for heart disease in the USA showed a striking inverse correlation with altitude in 1979, before the sun scare. American populations at the highest altitude had about half the heart disease of sea level populations. Thirty-five years ago, Leaf observed that most of the long-lived populations in the world reside at high altitude. Dr. Scragg showed that higher vitamin D levels are associated with lower risk for heart attack.

Facts about Cholesterol

Click on items below for scientific evidence.

1 Cholesterol is vital to cell health. A high cholesterol is not dangerous by itself.

2 Scientific studies show that people with low blood cholesterol have as much atherosclerosis and coronary heart disease as people with high cholesterol.

3 The human body produces most its cholesterol. Diet has little influence.

4 No evidence exists to show that animal fat and dietary cholesterol cause heart attacks. Plaque formation seen at autopsy is unrelated to dietary cholesterol or fat.

5 Drugs that lower cholesterol do not lower the overall death rate significantly. In fact, cholesterol lowering drugs may shorten life.

6 Statin drugs may reduce heart disease somewhat, but that is the result of other mechanisms unrelated to cholesterol. Unfortunately, they may also stimulate cancer, cause muscle damage and birth defects.

7 The effect of cholesterol on cardiovascular disease is widely discredited in scientific journals and text books.

8 Companies that market statin drugs choose to ignore the scientific evidence. The public is deceived.

9 Higher Cholesterol has many benefits: 1) People with high cholesterol live the longest. 2) Studies show that low cholesterol is in certain respects worse than high cholesterol. 3) Cholesterol protects against infection. 4) People with low cholesterol die younger.

The above facts do not apply to a small group of people (approximate incidence 0.2%) who inherit a familial type of genetic mutation causing very high cholesterol's levels (usually greater than 400 mg/dL), with fatty deposits in the skin and tendons (xanthomas), and family history of premature death.

Vitamin D Shortage


I was picking up a few things at the health food store the other night and vitamin D3 was on my list. I live in a northern climate and don't get much sun during the winter months. When I got to the section where hundreds of different brands of vitamin D once stood, I found that the shelves were almost bare! The store clerk told me they were having a hard time keeping it on the shelf. There are a lot of studies that have come out recently as to the health benefits of this little power house.

Look at the following video from ABC News that talks about the benefits of vitamin D on your health. Click on the following link to watch.

Vitamin D and Your Heart

No matter what the medical establishment and the sunscreen industry say, your body has a physical need for sunlight. You probably already know that your skin reacts to sunlight by making vitamin D. Some evidence suggests a dearth of vitamin D may be associated with an array of more serious illnesses, including immune-system disorders such as multiple sclerosis, rheumatoid arthritis and diabetes. But you may not know just how beneficial vitamin D really is. Here’s just a sample of its clinically proven power.


  • Elevates mood and boosts mental performance

  • Prevents many types of cancers, including prostate, breast and ovarian

  • Reduces the risk of melanoma

  • Halts and even reverses the effects of bone diseases like rickets, osteomalacia and osteoporosis

  • Relieves depression and lessens the symptoms of schizophrenia

  • Enhances the function of your pancreas

  • Increases insulin sensitivity and prevents diabetes

  • Promotes weight loss

  • Provides more restful sleep

  • Lends energy, vitality, and stamina

  • Lowers blood pressure

  • Brings high blood sugar levels down

  • Lowers the amount of bad cholesterol in your blood

  • Increases white blood cell activity and strengthens immunity

  • Increases muscle strength and coordination

The following video is nothing short of amazing. It talks about the miracle of vitamin D and how it can help prevent everything from colds to a 60% reduction in cancer. Supplementing with vitamin D could also be a better choice than taking a flu shot!

Vitamin D: Essential for Prevention of Diseases





So how much do you need? I don't think that has been determined yet, but we do know how much the body uses on a daily basis. In a study performed at Creighton University in Omaha, researchers found that adults will use 3,000 to 5,000 units of vitamin D per day, if it is available. We also know that a young adult with fair skin makes 20,000 units of vitamin D in less than half an hour of strong sun exposure. Many scientists have begun pushing to sharply boost the official recommendations for how much vitamin D everyone should get daily, either by taking supplements or by getting more sun exposure. If you think you can get all the vitamin D you need from the food you eat, think again. To put it in perspective, look at how much vitamin D you would get from various foods compared to sunshine.

  • 8 oz. glass of fortified milk has 100 IU and equals 45 seconds of sunshine
  • 1 egg has 20 IU and that equals 8 seconds of sunshine
  • 1 tablespoon of butter has 8 IU and that equals 5 seconds of sunshine
  • Fish (canned or fresh) contains 200-400 IU and that equals 1.5-3 minutes of sunshine.
  • Cod Liver Oil contains 1360 IU and is equivalent to 8 minutes of sunshine
  • Total American Daily Diet contains 200-250 IU which is equal to 1.5-2 minutes of sunshine
*Calculated at maximum total-body sun exposure for one-half hour at noontime in the summer sun at a southern latitude= 10,000 IU. This is a very optimistic estimate which assumed ideal conditions to produce natural vitamin D. In real life, probably 10-fold more time needs to be spent in the sun to produce the amount of vitamin D levels above. Source: The Uncensored Family Guide To Vitamin D.

Michael F. Holick, a Boston University scientist argues that instead of the 200 to 600 international units a day that current recommendations suggest, most people should be getting at least 1,000 units a day. In a controversial new book, "The UV Advantage," Holick recommends exposing the hands, face, arms and legs to the sun for five to 15 minutes a day a few days a week, which he says would be enough to generate that amount without increasing the risk for skin cancer. Many people are not getting even that amount of sun exposure on a regular basis, Holick and others say.

But when the sun is low in the sky during winter, it can be difficult to get enough sun exposure, even if you spend time outdoors. Many cancers, most notably breast, colon and prostate cancer, seem to increase the farther you get from the equator, where exposure to ultraviolet light from the sun is greatest.

If you are an African American, you are at even greater risk. The darker your skin, the more UVB rays from the sun are filtered out or blocked. These are the type of rays that cause the skin to naturally produce vitamin D. African Americans have about half the levels of vitamin D than lighter skinned peoples. "The highest rate of prostate cancer is among African Americans, followed by countries in northern Europe. How are blacks like Scandinavians? They don't look alike, but in some important ways they have to be alike," said Gary G. Schwartz, a cancer researcher at Wake Forest University School of Medicine. "One way that they are alike is both groups have very low levels of vitamin D." African Americans may be suffering from unrecognized deficiencies of vitamin D that increase the risk of bone problems and perhaps a host of other diseases, a growing number of scientists say. One federal study of women nationwide found that perhaps nearly half of African American women of childbearing age may be vitamin D deficient.
Black Americans, who are often vitamin D–deficient, are more prone to contracting tuberculosis than are whites, and tend to have a more aggressive form of the disease.

While there could be many other explanations, the idea that vitamin D may help prevent malignancies has been buttressed by animal and laboratory studies indicating it can act as a brake on cell growth, preventing the uncontrolled cell division that is cancer.
Similarly, vitamin D appears to damp down the immune system, and researchers have also found associations among sun exposure, vitamin D levels and the incidence of "autoimmune diseases" such as multiple sclerosis, lupus and diabetes, in which the immune system attacks the body.

Some studies suggest vitamin D can reduce blood pressure, which would cut the risk for heart disease and strokes -- the nation's leading causes of death. Others suggest that low vitamin D levels may contribute to depression and other psychiatric conditions.

According to Dr. Louise Parker, vitamin D is proving to have an affect on many different cancers. She is an epidemiologist and a world expert in the environmental exposures that can lead to cancer. " On the average, 1000 units per day is safe and is probably effective in reducing the risk of colon cancer, and maybe other cancers as well," says Dr. Parker.

Vitamin D can help prevent hip fractures and osteoporosis in the elderly. If calcium is the vehicle to healthy bones and avoidance of osteoporosis, then vitamin D3 is the highway. Studies show patients with osteoporosis treated with vitamin D3 increased calcium absorption and reduced bone loss. Vitamin D needs magnesium to convert it to its most active form. If there is depletion in magnesium, this can lead to a syndrome of vitamin D resistance.


The Journal of Nutrition, Health and Aging reported that vitamin D supplementation had a greater benefit towards relieving the symptoms of seasonal affective disorder (SAD) and the depression associated with it. Click on the following link to read about the study.

If you think that you might have low levels of vitamin D in your blood, you can have your doctor do a D25-hydroxy blood test to see what your levels are. A regular blood panel will not determiine this. It must be a D25-hydroxy test to measure you vitamin D3 levels. Make sure you are specific about asking for this test.

Supplemental vitamin D and calcium reduces risk of diabetes



The incidence of type-2 diabetes is lower among women who get adequate calcium and supplement with vitamin D. Researchers used data from the Nurses Health Study, which includes over 83,000 women, to study the relationship of calcium and vitamin D intake to type-2 diabetes.

After 20 years of follow-up, it was concluded that a combined daily intake of over 1,200 mg of calcium and more than 800 IU of vitamin D was associated with a 33 percent lower risk of type-2 diabetes. Interestingly, dietary vitamin D intake did not appear to provide any statistically significant benefit. But the women who supplemented with at least 400 IU of vitamin D had a 13% lower risk of diabetes when compared to those who took less than 100 IU per day. Both dietary and supplemental calcium resulted in decreased risk of type-2 diabetes, and those with overall intakes above 1,200 mg had a 21% lower risk than those who got less than 600 mg per day.

Elevated intakes of calcium and vitamin D, especially from supplements, are significantly associated with lower incidence of type-2 diabetes.
