Natural Eradication of Cardiovascular Disease


Natural Eradication of Cardiovascular Disease

Every second man and woman in the industrialized world dies from the consequences of atherosclerotic deposits in the coronary arteries (leading to heart attack) or in the arteries supplying blood to the brain (leading to stroke). The epidemic spread of these cardiovascular diseases is largely due to the fact that, until now, the true nature of atherosclerosis and coronary heart disease has been insufficiently understood.



Conventional medicine is largely confined to treating the symptoms of this disease. Calcium antagonists, beta-blockers, nitrates and other drugs are prescribed to alleviate angina pain. Surgical procedures (angioplasty and bypass surgery) are applied to improve blood flow mechanically. Rarely does conventional medicine target the underlying problem: the instability of the vascular wall, which triggers the development of atherosclerotic deposits.

Cellular Medicine provides a breakthrough in our understanding of the underlying causes of these conditions and leads to the effective prevention and treatment of coronary heart disease. The primary cause of coronary heart disease and other forms of atherosclerotic disease is a chronic deficiency of vitamins and other essential nutrients in millions of vascular wall cells. This leads to the instability of the vascular walls, lesions and cracks, atherosclerotic deposits and, eventually, heart attacks or strokes. Since the primary cause of cardiovascular disease is a deficiency of essential nutrients in the vascular wall, the daily optimum intake of these essential nutrients is the primary measure to prevent atherosclerosis and help repair artery wall damage.

Scientific research and clinical studies have already documented the particular value of vitamin C, vitamin E, beta-carotene, lysine, proline and other ingredients in Dr. Rath’s Cellular Health recommendations for preventing cardiovascular disease and improving the health of patients with existing cardiovascular disease.

Vitamins and Other Nutrients Can Halt and Reverse Coronary Heart Disease

Millions of people die every year from heart attacks because no effective treatment to halt or reverse coronary heart disease has been available. Therefore, we decided to test the efficacy of Dr. Rath’s Cellular Health recommendations for the number one health problem of our time: coronary atherosclerosis, the cause of heart attacks. If these Cellular Health recommendations were able to stop further progression of coronary atherosclerosis, the fight against heart attacks could be won and the goal of eradicating heart disease would become a reality.

To measure the success of this program, we did not primarily look at risk factors circulating in the bloodstream. We focused directly on the key problem, the atherosclerotic deposits inside the walls of the coronary arteries. A fascinating new diagnostic technique had just become available that allowed us to measure the size of the coronary deposits non-invasively: Ultrafast Computed Tomography (Ultrafast CT).

Ultrafast CT measures the area and density of calcium deposits without the use of needles or radioactive dye. The computer automatically calculates their size by determining the Coronary Artery Scan (CAS) score. The higher the CAS score, the more calcium has accumulated, which indicates more advanced coronary heart disease.

Compared to angiography and treadmill tests, Ultrafast CT is the most precise diagnostic technique available today to detect coronary heart disease already in its early stages. This diagnostic test allows the detection of deposits in the coronary arteries long before a patient notices angina pectoris or other symptoms. Moreover, since it directly measures the deposits in the artery walls, Ultrafast CT is a much better indicator of a person’s cardiovascular risk than measurements of cholesterol or other risk factors in the bloodstream.


Before following Dr. Rath’s Cellular Health recommendations, the patient had developed atherosclerotic deposits in the walls of his left coronary artery (white circled area in the left picture). The scans below are magnifications of the heart scan taken with Ultrafast CT.

We studied 55 patients with various degrees of coronary heart disease. Changes in the size of the coronary artery calcifications in each patient were measured over an average period of one year without vitamin supplementation, followed by one year with Dr. Rath’s Cellular Health recommendations. In this way, the heart scans of the same person could be compared before and after the vitamin program. This study design had the advantage of patients serving as their own controls.

The results of this study were published in the Journal of Applied Nutrition. The full text of this landmark study is documented at the end of this book. The most important findings can be summarized as follows: This study measured, for the first time, how aggressive coronary heart disease progresses until eventually a heart attack occurs. Without the use of Cellular Health recommendations, the coronary calcifications increased at an exponential rate (very fast) with an average growth of 44% every year. Thus, without vitamin protection, coronary deposits increased approximately half their size every year.

When patients followed the Cellular Health recommendations, this trend was reversed and the average growth rate of coronary calcifications actually slowed down. Most significantly, in patients with early stages of the disease, this essential nutrient program stopped further progression of coronary heart disease within one year. This study also gives us valuable information about the time it takes for the Cellular Health recommendations to show a repair effect on the artery wall.

While for the first six months the deposits in these patients continued to grow, albeit at a decreased pace, the growth essentially stopped during the second six months with the vitamin program. Of course, any therapy that stops coronary heart disease in its early stages prevents heart attacks later on.

It is not surprising that there is a delay of several months until the healing effect of these Cellular Health recommendations on the artery wall becomes noticeable. Atherosclerotic deposits develop over many years or decades, and it takes several months to control this aggressive disease and start the healing process. More advanced stages of coronary heart disease may take still longer before the vascular healing process is measurable. To determine this, we are continuing our study.

Can already existing coronary deposits be reversed in a natural way? The answer is yes. In individual patients, we documented the natural reversal and complete disappearance of early coronary artery deposits approximately within one year. The ongoing study will tell us how long the natural reversal takes in patients with advanced coronary artery disease.

The complete natural disappearance of atherosclerotic deposits with Dr. Rath’s Cellular Health recommendations confirms that this vitamin program contains the essential ingredients needed to start the natural healing process of the artery wall.

In patients with early coronary heart disease, this healing of the artery wall can lead to the complete, natural disapearance of atherosclerotic deposits.

In patients with advanced coronary artery disease, these Cellular Health recommendations can stabilize the artery walls, halt the further growth of coronary deposits, reverse them, at least in part, and contribute to the prevention of heart attacks.

Coronary Heart Disease Is an Early Form of Scurvy

Dr. Rath’s Scientific Discovery in Heart Disease

Dr. Rath’s research reveals that coronary heart disease occurs exactly for the same reason that clinical (early) scurvy does – a deficiency of vitamin C in the cells composing the artery wall. Humans, unlike animals, develop heart disease because their bodies cannot produce vitamin C. The average diet provides enough vitamin C to prevent scurvy, but not enough to guarantee stable artery walls. As a consequence of vitamin C deficiency, millions of tiny cracks and lesions develop in the artery walls. Subsequently, cholesterol, lipoproteins and other blood risk factors enter the damaged artery walls to repair these lesions.

In the case of chronic vitamin deficiency, this repair process becomes continuous. Over the course of many years, atherosclerotic deposits develop. Deposits in the arteries of the heart eventually lead to heart attack; deposits in the arteries of the brain lead to stroke.

Dr. Rath identified and our research has proven that atherosclerosis is nature’s plaster cast for weak and cracked arterial walls that are chronically deficient in vitamin C and other essential nutrients. One of these nutrients is the amino acid lysine. Lysine is called an essential amino acid because, similar to vitamin C, it cannot be produced in the human body. Lysine, together with another amino acid, proline, is the main component of collagen. These two amino acids comprise about 25% of all amino acids in the collagen molecule. A deficiency of lysine and proline can also trigger blood vessel wall weakness and instability.

Research and clinical studies conducted by Dr. Rath confirm that the most important function of vitamin C in preventing heart attacks and strokes is its ability to increase the production of collagen, elastin, and other reinforcement molecules in the body. This groundbreaking discovery in heart disease should be taught in every medical textbook and school and explains why other cardiovascular conditions, including heart failure, irregular heartbeat, high blood pressure and circulatory problems in diabetes, occur in the case of long-term vitamin deficiencies.

The Cholesterol Myths

UFFE RAVNSKOV
author of The Cholesterol Myths

UFFE RAVNSKOV is radical. He is so radical that, on a television show in Finland, his critics set his book on fire!

His website (or a website about him) says: If you think this is written by another internet crackpot, take a look at Dr Ravnskov's credentials and the reviews of his book.

The book in question is titled The Cholesterol Myths. Its main argument is that cholesterol is not harmful to health but, in fact, healthy. Its author is certainy no internet crackpot. His credentials are, indeed, impressive.
Uffe Ravnskov graduated with a medical degree in 1961 and, in 1973, obtained a PhD in Chemistry. Between 1975 and 1979, he was Assistant Professor at the Department of Nephrology, University Hospital, in Lund, Sweden. Ravnskov went into private practice in 1980 and, in 2000, retired to become a full-time independent researcher.

More significantly, Uffe Ravnskov has published over 80 scientific papers and letters in peer-reviewed journals criticizing what is commonly called the Lipid Hypothesis of heart disease – the belief that dietary saturated fats and cholesterol clog arteries and cause atherosclerosis and heart disease.
Uffe Ravnskov began studying cholesterol in 1989, the year Sweden launched an anti-cholesterol campaign.

“Very soon I realised that the scientific evidence behind the campaign was non-existing,” he writes.

Among the many research findings published in scientific journals, Uffe Ravnskov discovered that:

lowering cholesterol did not result in lower death rates from heart disease, but in HIGHER death rates from all causes.

drug trials with an allegedly positive outcome was cited almost only by the trial directors, although the numbers of trials with an allegedly positive and a negative outcome were identical.

the successful dissemination of the diet-heart idea is due to authors systematically ignoring or misquoting discordant studies.
Uffe Ravnskov also discovered that LDL, commonly called “bad cholesterol”, actually protects against infections. This led him to put forward the hypothesis that high cholesterol, rather than promoting atherosclerosis, in fact may protect against it.

Uffe Ravnskov first summarised his research findings in a book, first published in Sweden in 1991, whose title translates to The Cholesterol Myths.

In 1992, the book was published in Finland. That was when his critics burned the book during a television show about it.

In 2000, an updated and expanded English edition of The Cholesterol Myths was published in the United States.

In 2002, a German edition of The Cholesterol Myths was published.

In his book, Uffe Ravnskov critically analyzes and demolishes the nine main myths of the Lipid Hypothesis:

High-fat foods cause heart disease
High cholesterol causes heart disease
High fat foods raise blood cholesterol
Cholesterol blocks arteries
Animal studies prove the diet-heart idea that diet affects heart disease
Lowering your cholesterol will lengthen your life
Polyunsaturated oils are good for you
The cholesterol campaign (to have people reduce their cholesterol levels) is based on good science
All scientists support the diet-heart idea.
All the above statements, Uffe Ravnskov maintains, are NOT TRUE. And he backs his assertions with solid scientific research.

Ancel Keys' Seven Countries Study

Uffe Ravnskov starts off with a critical analysis of the original 1950s research that gave rise to the idea that saturated fats and cholesterol cause heart disease – Dr Ancel Keys Six Countries Study, which later became the more famous Seven Countries Study published in 1980.

The Seven Countries Study – which gathered data on heart disease of some 13,000 men in Greece, Italy, Croatia, Serbia, Japan, Finland and the Netherlands over several decades – is widely considered to be one of the greatest epidemological studies ever undertaken.

Ancel Keys' Seven Countries Study showed that countries with the highest animal fat intake have the highest rates of heart disease. And this is frequently cited as “proof” that saturated fats and cholesterol cause heart disease.

Uffe Ravnskov informs us, however, that Ancel Keys had deliberately hand-picked the countries he included in his studies. In other words, Ancel Keys chose to study only those countries that supported his hypothesis.

Yet there are many other countries where high consumption of animal fat DID NOT cause heart disease. But, Ufee Ravnskov points out, Ancel Keys ignored those countries.

Dangers of statins and other cholesterol lowering drugs

Uffe Ravnskov is also highly critical of statins, the cholesterol-loweing drugs that are widely hailed as miracle “wonder drugs”.

He presents scientific evidence that show:

drug trials involving statins produced only neglible reductions in the rates of heart disease
lowering cholesterol did not reduce the death rate from heart disease but INCREASED the overall death rate from all causes
whatever positive benefits associated with the use of statins are due to factors other than cholesterol-lowering.
statins are probable carcinogens and women on statins have reported higher rates of breast cancer.
Uffe Ravnskov warns that exposure to carcinogens may result in cancer only after 20 or more years. And since there has not been controlled studies on statins over such long periods, we do not know whether the use of statins will lead to increased rates of cancer in the coming decades.

"“Millions of people are being treated with medications the ultimate effects of which are not yet known.”
– Uffe Ravnskov

Of course, it is not just Uffe Ravnskov saying all this and more. What he tells us about saturated fats and high cholesterol foods comes mainly from studying the reports of other scientists. He further tells us that…

The reason why laymen, doctors and most scientists have been misled is because opposing and disagreeing results are systematically ignored or misquoted in the scientific press.

Cholesterol sceptics

Myth Number 9 in Uffe Ravnskov's book is that “All scientists support the diet-heart idea.”
This certainly is not true and Uffe Ravnskov has gathered a large – and growing – group of doctors, scientists, academics and science writers in The International Network of Cholesterol Skeptics (THINCS).

Members of the group may disagree about what causes heart disease. But they share one thing in common.

The website of THINCS state:
"For decades, enormous human and financial resources have been wasted on the cholesterol campaign, more promising research areas have been neglected, producers and manufacturers of animal food all over the world have suffered economically, and millions of healthy people have been frightened and badgered into eating a tedious and flavorless diet or into taking potentially dangerous drugs for the rest of their lives.
As the scientific evidence in support of the cholesterol campaign is non-existent, we consider it important to stop it as soon as possible."

Saturated Fat - The misunderstood nutrient

by by Vreni Gurd | Fri, 04/06/2007 - 11:15pm

We are told that saturated fat and trans fat are terrible for us. The distinction must be made. Saturated fats are healthy, trans fats are not.
Saturated fats have been vilified as being the cause of heart disease, some cancers, and the obesity epidemic. Although heart disease and cancer were rare before 1920, the incidences of these diseases have increased dramatically since then. By as early as 1950, heart disease was the leading killer of Americans. However, contrary to what one would expect if the saturated fat/heart disease hypothesis were true, the consumption of animal fat between 1910 and 1970 DECREASED by 21% and the consumption of butter DECREASED from eighteen pounds per person per year to only four, according to the research of Sally Fallon and Mary Enig. Furthermore, over that same time span the consumption of refined vegetable oils much of it consumed as partially hydrogenated or trans fat, INCREASED by 400%, and the consumption of sugar and processed foods INCREASED by 60%. Current Canadian 2006 data (thank you Chris Williams!) suggest that those trends are continuing, with a continued decrease in the consumption of high saturated- fat foods like full-fat milks, eggs and red meat between 1970 and 2006. Since 1981, butter consumption (a saturated fat) has decreased by a third, while the consumption of salad oil (refined and therefore rancid polyunsaturated vegetable oils) has more than tripled. Shortening consumption (a trans fat) has remained relatively constant. So considering the continued decline in saturated fat consumption, blaming heart disease on saturated fat makes no sense (see this study published in the Lancet). To fully understand how it is possible that we find ourselves in this position where we are being told to eat refined polyunsaturated vegetable oils which are disease-causing and avoid saturated fats which are health promoting, read The Oiling of America by Mary Enig, PhD, fats and oils researcher, and Sally Fallon. The insight into the politics of food is scary.

All fats and oils are made up of a mixture of saturated, mono and polyunsaturated fatty acids. Calling animal fats "saturated fats" is very misleading, as many animal fats are actually more than 50% unsaturated, and chicken fat is actually 70% unsaturated. If a fat were completely saturated it would be very solid with the consistency of hard wax. For example, beef fat or tallow is made up of about 50% saturated fatty acids (25% palmitic acid, 22% stearic acid and others), 40% monounsaturated fatty acids (oleic acid, the main fatty acid in olive oil), and the balance polyunsaturated fatty acids (linoleic and linolenic, the ratio depending on the diet of the cattle).

Saturated fatty acids are critical to maintaining the structure and rigidity of our cells by making cell membranes out of phospholipids and cholesterol, and they act as enzyme and hormone regulators thereby playing an integral role in cell messaging. When the body is fooled and incorporates trans fats into the cell membrane instead of saturated fats, cell messaging no longer works, which is one of the reasons trans fats are so dangerous.

Saturated fats are necessary for calcium to be incorporated into our bones, so no-fat or skim milk won't work as a calcium source, unless you eat some saturated fat in your meal. Saturated fats are needed to boost immune function, and to build a healthy nervous system and digestive tract. Saturated fats are the base material out of which the body makes cholesterol, which is the precursor to such critical hormones as vitamin D, cortisol, testosterone, estrogen and progesterone, as well as bile acids which are necessary for the digestion of fats. Fats also are needed as carriers for the fat soluble vitamins (the antioxidant vitamins), like vitamin A, E, D, K, and a low fat diet can lead to deficiencies in these nutrients. Saturated fats are also needed to be able to utilize omega 3 fatty acids easily. Breast milk is high in saturated fat for a reason - it is vital for the healthy development of the baby! Does it make sense that saturated fats which are vital for a baby are suddenly poison for an adult?

Fat is also needed to feel satisfied after a meal. Mary Enig says in her book Know Your Fats: The Complete Primer For Understanding the Nutrition of Fats, Oils, and Cholesterol that "as a result of the presence of fat in the small intestine, special hormones are produced that prevent hunger contractions. ... Too much fat in the diet and the loss of weight is thwarted; too little and the hunger pangs play havoc with good intentions and usually lead to overeating carbohydrates."

Saturated fatty acids can be broken down into three groups - short chain, medium chain and long chain. The short and medium chain saturated fatty acids don't turn into body fat unless consumed in very large quantities, but rather are utilized immediately by the body for energy. Therefore fats that contain more short to medium chain fatty acids have less calories than the same amount of longer chain fatty acids. According to Mary Enig, in her book Know Your Fats: the Complete Primer for Understanding the Nutrition of Fats, Oils and Cholesterol, a pound of coconut oil has 100 kilocalories less than a pound of soybean oil. And yes, butter has less calories than margarine, although not much less.

If you are eating high quality fats, such as pasture fed, non-medicated, organic eggs, dairy, poultry, and meat, you are doing your body good. If you are eating conventionally raised poultry and meat, it is a good idea to cut off the fat, as the medications, hormones and pesticides consumed by the animal will be concentrated in the fat, which will in turn be concentrated in your fat. Cook only with pasture-fed organic butter, ghee, tallow or chicken fat, or organic coconut oil, or unrefined or cold pressed extra virgin olive oil (low to medium temperatures only), as these fats are stable and won't oxidize and go rancid when heated. To find out what ratio of fat, protein and carbohydrates are appropriate for you according to your own personal biochemistry, get yourself metabolically typed at Healthexcel, and receive a food list of appropriate foods for you. Some people require more quality fats to be healthy than others.

High Cholesterol does NOT cause heart disease

by Vreni Gurd | Fri, 04/13/2007 - 11:48pm

The lipid hypothesis needs to be re-evaluated - it has very serious flaws.
First of all, it is important to understand that that "risk factor" does not mean the same thing as "cause". A risk factor is a characteristic that is associated with a diagnosis. For example, for women, being tall is associated with breast cancer. Does that mean that being tall causes breast cancer? Of course not.

It is also important to understand cholesterol is an essential component of our cell membranes, it acts as an anti-oxidant, it is a precursor for the synthesis of vitamin D as well as bile for digesting fats, and is the only source out of which our steroid hormones, such as cortisol, as well as estrogen, progesterone and testosterone which are key to reproduction, can be made. Therefore it is safe to say that without cholesterol we would not survive. Cholesterol is also the precursor to calcitrol, the steroid hormone that regulates calcium levels in our bodies by helping us absorb calcium from our food, thus playing a key role in the mineralization of our bones and teeth. Cholesterol is also manufactured in the glial cells of the brain to aid with synapses.

Cholesterol is used by our bodies to repair lesions in the arteries. Dr. Mary Enig, fat researcher, suggests that blaming cholesterol for heart disease is something like blaming firefighters for starting fires. Is it really a good idea to reduce our arteries' firefighters? The key to stopping heart disease is to stop the lesions (fires) in the arteries from occurring in the first place, by minimizing glycation by eating less sugar and high fructose corn syrup, and minimizing free radical damage by not consuming refined and therefore rancid vegetable oils AND by reducing systemic stress.

Our bodies consider cholesterol to be so essential to our survival, that every cell in our body can manufacture it as needed. If we eat little or no cholesterol, our bodies manufacture more, and if we eat a lot, our bodies don't manufacture as much. This way our cholesterol levels maintain homeostasis irrespective of our diet, and this is the reason it is so difficult to reduce or raise cholesterol levels much with diet alone.

Dr. Uffe Ravnskov, MD, PhD, who wrote the book The Cholesterol Myths, goes through study after study destroying the idea that high cholesterol levels are the cause of heart disease. In the Framingham heart study done near Boston that spanned 30 years , the researchers concluded that high cholesterol was a risk factor for heart disease, but when one really dissects the data, one must question how they came to that conclusion. For example, when the participants of the study are plotted on a graph it clearly shows that those with cholesterol levels between 182 and 222 did not survive as long as those with higher cholesterol levels of between 222 and 261. The study shows that about half the people with heart disease had low cholesterol, and half the people without heart disease had high cholesterol.

Most studies have found that for women, high cholesterol is not a risk factor for heart disease at all - in fact, the death rate for women is five times higher in those with very low cholesterol. In a Canadian study that followed 5000 healthy middle-aged men for 12 years, they found that high cholesterol was not associated with heart disease at all. And in another study done at the University Hospital in Toronto that looked at cholesterol levels in 120 men that previously had heart attacks, they found that just as many men that had second heart attacks had low cholesterol levels as those that had high. The Maoris of New Zealand die of heart attacks frequently, irrespective of their cholesterol levels. In Russia, it is low cholesterol levels that are associated with increased heart disease. The Japanese are often cited as an example of a population that eat very little cholesterol and have a very low risk of heart disease. But the Japanese that moved to the US and continued to eat the traditional Japanese diet had heart disease twice as often as those that maintained the Japanese traditions but ate the fatty American diet. This suggests that it is something else, like stress perhaps, that is causing the heart disease.

Dr. Malcolm Kendrick noticed that in the MONICA study that has been going on for about 40 years, there is no association between high cholesterol levels and heart disease. See the graph for yourself at the bottom of the article. (Dr. Kendrick wrote another interesting piece about the "disappointing results" of low fat diets in the Women's Health Initiatives heart intervention study, and the lack of association between death rates from CVD and saturated fat consumption based on the MONICA study).

These are but a small sample of the studies that contradict the idea that cholesterol is the villain in heart disease. So why has this idea held on so long? Perhaps pharmaceutical companies and the processed-food industry have a lot to gain by keeping this belief alive. Statin drugs (Lipitor, Mevacor, Zocor etc.) are mega money makers, and they definitely do lower cholesterol, but if high cholesterol does not cause heart disease, why are they necessary?

Furthermore, statin drugs may not lower overall mortality rates, as lower cholesterol levels seem to be associated with higher rates of cancer. Statin drugs work by blocking the synthesis of mevalonate, which is a vital step in the body's
synthesis of cholesterol. By blocking this step, every following step is also blocked, and this is a problem, because the synthesis of Coenzyme Q10 (ubiquinone) and squalene, both precursors to cholesterol, is also blocked. Coenzyme Q10 is very important for heart function, it acts as an antioxidant in conjunction with Vitamin E, and it is important in energy metabolism in the mitochondria of muscles, which is why muscle pain is a common side effect of statin drugs. Coenzyme Q10 is important for healthy brain function as well, and when Coenzyme Q10 levels are low, through statin use or otherwise, memory is affected. Squalene is also an antioxidant and is a potent cancer fighter. If you are on statin drugs, supplementing with Coenzyme Q10 and squalene may be very helpful.

I realize that suggesting that cholesterol levels are not associated with heart disease goes against current dogma. I am not making this suggestion in order to create controversy. After looking at the evidence, I am convinced that we are going down the wrong path. I am not alone in thinking this way - there are more and more scientists and physicians that believe that cholesterol and saturated fat stand wrongly accused. For me, the epidemiological evidence is most convincing. If we ate saturated fat and cholesterol in the form of animal fats, eggs, and full-fat dairy liberally for millennia and were heart-disease free up until the early 1900s, and just as we reduced our consumption of these foods and replaced them with sugar, vegetable oils and processed food, heart disease rates began to climb - to me it seems rather obvious that we are putting the blame on the wrong thing. Feel free not to believe this idea, but please don't simply dismiss it out of hand, either. If you have high cholesterol and you are taking, or thinking about taking cholesterol-lowering drugs, please read The Cholesterol Myths: Exposing the Fallacy that Saturated Fat and Cholesterol Cause Heart Disease so that you can make an informed decision regarding this important issue. Two other very well researched books worth reading, written by scientists but geared to the lay person are Nutrition and Physical Degeneration, by Dr. Weston A. Price, on primitive cultures, their health and their eating habits versus more modern cultures, their health and their eating habits (probably the most important book on nutrition ever written), and Mary Enig's book on lipid chemistry, Know Your Fats: The Complete Primer For Understanding the Nutrition of Fats, Oils and Cholesterol. These books are each very different from the other, but they will open your eyes to the other side of the argument, and only then will you be able to come to an informed conclusion on this issue.

Calcium and vitamin D enhance heart health benefits of weight loss

Weight loss and reduced waist circumference are related to an improvement in heart health and factors related to metabolic syndrome. According to a new study, supplementing with calcium and vitamin D during weight loss enhances heart health benefits in women with typically low calcium intake.

Recent research has shown that overweight individuals with low calcium and dairy consumption are at increased risk of developing metabolic syndrome. The findings suggest that adequate calcium intake could create a healthier metabolic profile similar to a balanced diet and regular exercise. In a new study, researchers investigated this issue by testing cardiovascular benefits of long-term calcium supplementation in women with usual low calcium intake. Healthy, overweight or obese women with a daily calcium intake of less than 800 mg/day were randomly assigned to 1 of 2 groups: the group consuming 2 tablets/day of a calcium + vitamin D supplement (600 mg elemental calcium and 200 IU vitamin D/tablet) or the group consuming placebo. Both groups completed a 15-week reduced calorie weight-loss program. Significant decreases in LDL cholesterol levels, as well as the ratios of Total to LDL and LDL to HDL were seen the calcium +D group. These changes were independent of the changes due to fat loss and reduced waist circumference. A tendency for more beneficial changes in HDL cholesterol, triglycerides, and total cholesterol was also observed in the calcium +D group.This was the first study to show that consumption of calcium +D during weight- loss enhances the beneficial effect of body weight loss on cardiovascular risk factors in overweight women with typically low calcium intake.

Inflammation and Vitamin D

Oxidative stress and inflammation is an underlying factor in the development of numerous age-related diseases. In clinical trials, vitamin D has been shown to suppress what is referred to as pro-inflammatory cytokines. This offers additional protection against conditions ranging from rheumatoid arthritis, prediabetes, heart failure, stroke, and heart disease.
It has become evident that those individuals who live in higher altitudes contract multiple sclerosis at much higher rates than those living where they get sunshine throughout the year. Scientists have identified specific vitamin D receptors in the white matter of the brain. The reduction in inflammation, which is the result of adequate vitamin D, may play a role in protecting you against developing multiple sclerosis.

Low Vitamin D levels increase cardiovascular risk

A report in the Archives of Internal Medicine (June 11,2007) added more evidence in the link of low vitamin D levels and heart disease. These researchers measured the 25-Hydroxy Vitamin D levels in over 15,000 women. Those women who had the lowest levels of vitamin D had significantly higher prevalence of hypertension, diabetes, and elevated triglyceride levels (the other fat in the blood other than cholesterol). These are all risk factors for heart disease and strokes.
These researchers again pointed out the fact that low vitamin D levels carry a significant risk factor to our health. They concluded that current intake of vitamin D is far to low for optimal health. This is why I recommend that my patients should get their vitamin D levels checked and act accordingly. First, to bring their vitamin D levels back up to the recommended level (at least greater than 50 ng/ml) and second, to maintain these levels by taking at least 1,000 to 1,200 IU of vitamin D in supplementation.

Lycopene and other antioxidants decrease risk of heart disease

As you have been learning, oxidized LDL cholesterol and not native LDL is our enemy because it causes such inflammation of our arteries. Fat soluble vitamins are important because they can actually incorporate themselves into the LDL particle. They have been shown to have the ability to then make this LDL cholesterol less likely to be oxidized by excessive free radicals.

Lycopene and other fat soluble vitamins have been shown to protect our LDL cholesterol from becoming oxidized in epidemiological studies and human trials. Therefore, these studies show a decreased risk of developing cardiovascular disease.
