Scattered studies have found that polyunsaturated fats inhibit the proteolytic enzymes involved in the digestion of food, in the removal of clots, in the formation of thyroid hormone, and many other essential physiological processes.
Some of the interesting enzymes affected specifically by polyunsaturated fatty acids are those involved in hormone production. While they inhibit the formation of progesterone and androgens, they activate the synthesis of estrogen, which in turn activates the release of more free polyunsaturated fatty acids from the tissues, in a positive feedback pattern.
The inhibition of detoxification enzymes by PUFA (Tsoutsikos, et al., 2004) affects many processes, such as the elimination of estrogen, contributing to the positive feedback between estrogen and the oils. The meaning of this tends to be lost, because of the estrogen industry's effective campaigns.
Another situation in which fatty acids participate in a positive feedback system is the stress reaction, in which the released fatty acids impair mitochondrial energy production, increasing the stress and leading to further release of fatty acids.
One of the perennial theories of aging that has remained viable is the metaplasm/lipofuscin/age pigment theory, the idea that a toxic material accumulates in tissues over time. The age pigment contains proteins, cross-linked PUFA, and metals. The inhibition of proteolytic enzymes is involved in its accumulation, and the ratio of PUFA to saturated fatty acids is an important factor in its formation. Estrogen is one of the factors that can promote the formation of age pigment, probably partly because its lipolytic action increases the cells' exposure to free fatty acids. The lipofuscin contributes to inhibition of proteolysis, probably partly through increased production of free radicals and hydrogen peroxide.
Diabetes, like cancer, has been known for a long time to be promoted by unsaturated oils in the diet, rather than by sugar. The seed oil industry has been more effective than the Sugar
industry in lobbying and advertising, and the effects can be seen in the assumptions that shape medical and biological research.

True or False?
1. Eating too much fat will make you fat.
2. Eating too much saturated fat causes heart disease.
3. Polyunsaturated fats like soy oil, corn oil, and safflower oil that you buy from the grocery store are good for your health.
4. If you’re trying to eat a healthier diet, you should choose margarine over butter.
5. Lard is a saturated fat.
6. Hydrogenated vegetable oils that almost all restaurants use to cook with, and that are found in tens of thousands of processed food products, are good for our bodies.
7. Fats should be limited to as little as possible for health reasons.
8. Cholesterol and saturated fat cause cardiovascular disease.
Answers found at the end.
Is it a Fat or an Oil?
To put it simply, they’re all fat whether in liquid form or solid. We tend to refer to them as oils if they’re liquid at room temperature like olive oil. And we refer to them as fat if they are solid at room temperature like beef tallow or butter.
Technically called lipids, fats and oils are made up of many different types of fatty acids. Fatty acids are the same whether they come from plants or animals. Oleic acid that is found in olive oil is exactly the same as the oleic acid found in lard (pig fat). It’s the proportions of fatty acids that will vary from plant to plant, from animal to animal, and from plant to animal.
Types of fats
A fatty acid is a molecule that is made up of a chain of carbon atoms. These chains can vary in length from 1 – 24 carbons. Fatty acids are given their names based of how long the chain is and at what position the “unsaturation” occurs. If the fatty acid is saturated, the carbon chain length determines the name.
What is a saturated fat? Each carbon atom in the fatty acid chain has room for two hydrogen molecules, except at the end, where it has room for three. A fatty acid possessing two hydrogen atoms for every carbon atom in the chain is said to be saturated. A fatty acid missing two or more hydrogen atoms along the chain, which causes double bonds between carbon atoms, is said to be unsaturated. If there is one double bond, the fatty acid is referred to as monounsaturated. If there are two or more double bonds found along the chain, the fatty acid is referred to as polyunsaturated.

Although olive oil is the best vegetable (it’s actually a fruit grown on trees) monosaturated fat to use in cooking because of its high oxidation threshold, it is not recommended for repeated use or deep frying. Purchasing extra virgin olive oil ensures that it has not been extracted with heat or detergents. Olive oil that is not labeled “Extra Virgin” comes to stores already denatured and containing high amounts of free radicals from the extraction process.
Sources: Corn oil, soy oil, safflower oil, sunflower oil, cotton seed oil, walnuts, flax oil, hemp oil, herring, salmon, sardines, mackerel.
Safflower, corn, sunflower, soybean and cottonseed oils all contain over 50% of the highly unstable fatty acid Omega-6 and should never be used in cooking, frying or baking. Heating these oils causes oxidation and produces large amounts of free radicals.
We have been force fed a load of crap concerning the virtues of polyunsaturated fats. We’ve been told relentlessly that polyunsaturated fats are good for our health and to increase our consumption. Unfortunately, polyunsaturated fats cause many health problems. One of the biggest reasons polyunsaturated fats are so unhealthy is because they are very susceptible to becoming oxidized or rancid when exposed to heat and light. The polyunsaturated oils you buy in grocery stores are already rancid.
The extraction process is the problem:
1. Throughout the entire process, these oils are exposed to oxygen.
2. The oil is extracted with mechanical pressing and heated to 230 degrees.
3. Then a chemical solvent is used to get what oil is left.
4. The solvent is then boiled off. Again exposing the oils to heat.
5. Because these oils become rancid, they are treated with deodorizers to get rid of the horrible smell.
6. Finally, most oils are then bleached to give them eye appeal. Americans love the light golden color.
Now, you go to the store to purchase soy oil, which has been touted as super healthy, not knowing that you’re actually purchasing a free radical cocktail that over time causes serious health problems.
Free radicals, or “chemical marauders” as some scientists refer to them, wreak havoc on our bodies.
Some of the problems they cause for us include:
* Attack cell membranes
* Cause damage to DNA/RNA strands, triggering mutations in tissues throughout the body
* Causes wrinkles and premature aging
* Damage to tissues and organs sets the stage for tumors
* Damage to blood vessels initiates plaque buildup
* Linked to autoimmune diseases like arthritis
* Linked to Alzheimer’s
* Linked to cataracts
Sources: Beef tallow (fat), dairy, palm oil, coconut oil.
Saturated fats’ roles in the body include: 
* They constitute at least 50% of our cell membranes and give our cells integrity.
* They play a vital role in the health of our bones.
* They lower Lp(a), a substance in the blood that is said to indicate proneness to heart disease.
* They protect the liver from alcohol and other toxins like Tylenol (Acetaminophen).
* They enhance the immune system.
* They are needed for proper utilization of essential fatty acids.
* Stearic acid and palmitic acid, both saturated fats, are the preferred energy source of the heart. This is why the fat around the heart muscle is mainly saturated. The best sources for palmitic acid are beef, butter and palm oil.
* Short and medium chain saturated fatty acids have strong antimicrobial properties. They help protect us from harmful microorganisms. The best sources are tropical oils such as coconut oil and palm oil.
Because the carbon atoms are saturated with hydrogen atoms, saturated fats are very stable and generally do not go rancid. These fats are the best sources for cooking because of their stability and the positive functions they play in our bodies.
Sources: Any foods containing “shortening,” “partially hydrogenated vegetable oil” or “hydrogenated vegetable oil” in the ingredients list.
Decades of research show the consumption of trans fats to be detrimental to health.
Trans fat’s roles in the body include:
* Lowers high density lipoproteins (HDL), otherwise known as the “good Cholesterol.” 
* Raises low density lipoproteins (LDL), otherwise known as the “bad cholesterol.” 
* Raises C-reactive protein, a substance in the blood that indicates arterial inflammation and is said to indicate proneness to heart disease. 
* Raises Lipoprotein (a) (Lp(a)), a substance in the blood that indicates arterial inflammation and is said to indicate proneness to heart disease. 
* Raises C-reactive protein, a substance in the blood that indicates arterial inflammation and is said to indicate proneness to heart disease. 
* Promotes improper management of blood sugar, thus having detrimental effects in diabetics. 
* Interferes with the function of the immune system. 
* Decreases the body’s ability to utilize and decreases the amount of the healthy omega-3 fatty acids in our tissues. 
What are trans fats? They are poison in our food supply. “The latest government study confirms that trans fat is directly related with heart disease and increases LDL cholesterol. Because of that, the Institute of Medicine, a branch of the National Academy of Sciences, declared there is no safe amount of trans fat in the diet.”  “There should be a warning on food made with this stuff like there is on nicotine products. It’s that bad for you, says Dr. Jeffery Aron, a University of California at San Francisco professor of medicine and one of the nation’s leading experts on fatty acids and their effect on the body. 
Poison is the most appropriate description of trans fat I can think of. These manmade fats are literally toxins in our bodies. Trans fat is produced through the process of hydrogenation. This process turns polyunsaturated oils into fats that are solid at room temperature, which are used to make products like margarine and shortening. To produce them, manufacturers begin with the cheapest oils, including soy, corn, cottonseed and canola, which are already rancid from the extraction process discussed earlier.
The oil is mixed with metal particles, usually nickel oxide, and is then subjected to hydrogen gas in a high-pressure, high-temperature container. Next, emulsifiers and starch are added to the oil/metal mixture to give it a better consistency.
At this time you have the base for margarine, only it smells like shit because it’s rancid and it’s gray from the metallic additive. Who would buy a spread like this? Nobody, that’s why it is then steam cleaned to get rid of the smell, and colors and flavors are added to make it resemble butter. This junk has actually been pushed onto us by industry, the American Heart Association and many physicians. Thanks a lot AHA, health food my ass.
Hydrogenation serves two main purposes. First, the process causes the hydrogen atoms to rearrange and makes a normally curved molecule straighter. The straighter the fat molecules are, the easier they pack. The unnaturally straighter molecules allow a fat that is normally liquid at room temperature, like soy oil, to be solid. Second, hydrogenation makes the naturally unstable polyunsaturated molecules more stable by destroying most of the omega-3 and omega-6 fatty acids, both essential for good health. Being unnaturally more stable, these fats extend the shelf life of processed foods.
At one time, tropical oils with anti-microbial properties like coconut and palm oils were the fats used in thousands of products we bought in grocery stores. These unusually healthy oils have been replaced by cheap, toxic, manmade hydrogenated oils. Oils like coconut oil and palm kernel oil are the best sources of lauric acid. Lauric acid has anti-microbial properties that inactivate viruses like HIV, measles, herpes simplex-1, vesicular stomatitis, visna and cytomeglovirus. 
Trans fat is toxic to our bodies, and as early as the 1940s, researchers found a strong correlation between cancer, heart disease and the consumption of hydrogenated fats, although the results were presented as though the culprit was saturated fats.  In fact, until recently, saturated fats were usually lumped together with trans fat in the various U.S. data bases that researchers use to correlate dietary trends with disease conditions. Because the FDA has turned a blind eye to the unreported levels of trans fat in foods, we have been misled about the fat composition of the foods we eat.
Amazingly, hydrogenated fats became classified as a health food and have been aggressively promoted as such by the edible oil and processed food industries. The sharp increase in the consumption of products like Crisco and margarine in the United States throughout the 1900s depicts the power of marketing over truth.
Thankfully, because of overwhelming evidence showing the dangers of trans fat, starting January 1, 2006, consumers will be able to find trans fat listed on nutrition labels. Supplement manufacturers will also be mandated to list trans fat on the supplement facts panel.
Buyer beware: Some of your favorite nutrition/protein bars, meal replacement powders and protein powders contain trans fat. Read your labels, but do not be fooled by products that claim “zero trans fat”. Showing the power the edible oil and processed food industries have, the FDA agreed to allow food labels to list the amount of trans fat as zero if it contains half a gram or less.
Americans have been told for more than four decades to decrease the amount of saturated fat in their diets. In the early 1900s, clogged arteries were a medical rarity at any age. In the 1920s, physicians who were trying to study cardiovascular disease (CVD) had to search the country for patients. When an internist named Paul Dudley White introduced his electrocardiograph to his colleagues at Harvard, they advised him to seek a more profitable branch of medicine. White’s invention is the single most used diagnostic tool in cardiac pathologies to date.
By the mid 1950s, CVD became our number one killer and remains the leading killer today. It was around this time that the lipid hypothesis started to gain popularity. The lipid hypothesis, which was proposed by Ancel Keys in the late 1950s, is a theory claiming there is a direct relationship between the amount of saturated fat and cholesterol in the diet and the incidence of CVD.
Today in the United States, one person will die from CVD every 35 seconds.  This year in the U.S., more than one million people will have a heart attack and just short of half of those sufferers will die.  Approximately 70 million people, or roughly 25% of the U.S., has cardiovascular disease.  In 2002, CVD mortality was nearly 60% of “total mortality” in the U.S. This means that out of 2.4 million deaths from all causes, CVD was listed as a primary cause on about 1.4 million death certificates.  CVD causes more deaths than the next seven causes combined. It’s safe to say CVD had a meteoric rise from the 1930s to the 1950s to become number one and to this day shows no signs of giving that position up.
If the lipid hypothesis were true, with the incidence of CVD still on the rise, one would surmise Americans have had a corresponding increase of their consumption of saturated fats and cholesterol. So what do Americans eat? How does our diet differ from the early 1900s?
Evolution of the unhealthy American
* Animal fat consumption has dropped over 21% since 1910. 
* Whole milk consumption has decreased 50%. 
* The consumption of butter has decreased from 18 pounds
per year to 4 pounds. 
* Over the past 80 years, cholesterol consumption has increased a mere 1%. 
* Vegetable oil consumption, including hydrogenated oils, has increased 437%. 
consumption went from 5 pounds
per year in 1900 to 163 pounds
per year today. 
If animal fats (saturated fats) are so dangerous, and vegetable oils (polyunsaturated fat) are so healthy, why are we so unhealthy as a nation? The scientific data of the past and present does not support the assertion that saturated fats cause heart disease. As a matter of fact, more than 20 studies have shown that people who have had a heart attack haven’t eaten any more saturated fat than other people, and the degree of atherosclerosis at autopsy is unrelated to diet.  Saturated fats have been nourishing societies around the world for thousands of years.
A study of more than one million males in India demonstrated that people in northern India consume more than seventeen times more animal fat than people in southern India. The incidence of CVD in northern India, however, is seven times lower than people in southern India. People in southern India consume much more vegetable oil than in the north. 
The French, despite eating 50% more saturated fat than Americans, die two and a half times less often from CVD. This phenomenon is referred to as the French paradox. But it is only a paradox if one believes saturated fat and cholesterol cause CVD. 
From 1951 to 1976, the consumption of animal fats in Switzerland increased by 20% despite a decrease in milk intake of 46%. Throughout this same period, smoking increased among women but remained the same among men. If the lipid hypothesis were correct, one would think mortality from cardiovascular disease would also increase. But to the disdain of the hypothesis proponents, mortality from CVD decreased by 22% in males and 46% in females. 
The Masai and Samburu tribes of Africa subsist almost completely on milk blood and beef. The Samburu may drink over a gallon of milk each day, which works out to well over one pound of butter fat. The Masai don’t drink as much milk as the Samburu, but eat more meat. Both tribes are virtually free from cardiovascular disease. 
The Japanese have the longest lifespan of any nation in the world, which is generally attributed to a low fat diet. The Japanese eat about one third of the dairy products as we do in the U.S., but it is still more than their total fish consumption per year. Their diets contain moderate amounts of animal fats from eggs, pork, chicken, beef, seafood and organ meats. Over the last 50 years, consumption of fats increased 15% and the mean cholesterol levels rose from a low 150 in 1958 to 188 in 1989. Despite the facts that the Japanese smoke much more than Americans and have increased their consumption of fats, they still live longer than any society in the world and have a very low incidence of CVD. 
I could go on and on with examples of what other societies eat that fly in the face of the lipid hypothesis, but I’ll end it here. It’s blatantly clear that there is no correlation in this country or any other that supports the lipid hypothesis.
In order for one to believe the lipid hypothesis, one has to believe cholesterol causes heart disease. I for one do not believe cholesterol causes heart disease and am also of the opinion that the lipid hypothesis is the biggest, most harmful scam in American history.
An excerpt from an article “Oiling of America” by Mary Enig, PhD and Sally Fallon.
In 1956, an American Heart Association (AHA) fund-raiser aired on all three major networks. The Master-Cleanse
interviewed, among others, Irving Page and Jeremiah Stamler of the AHA, and researcher Ancel Keys. Panelists presented the lipid hypothesis as the cause of the heart disease epidemic and launched the Prudent Diet, one in which corn oil, margarine, chicken and cold cereal replaced butter, lard, beef and eggs. But the television campaign was not an unqualified success because one of the panelists, Dr. Dudley White, disputed his colleagues at the AHA. Dr. White noted that heart disease in the form of myocardial infarction was nonexistent in 1900 when egg consumption was three times what it was in 1956 and when corn oil was unavailable. When pressed to support the Prudent Diet, Dr. White replied: "See here, I began my practice as a cardiologist in 1921 and I never saw an MI patent until 1928. Back in the MI free days before 1920, the fats were butter and lard and I think that we would all benefit from the kind of diet that we had at a time when no one had ever heard the word corn oil."
There have been opponents to the lipid hypothesis from the beginning, but the powerful edible oil industry and processed food manufacturers, who stood to gain the most from the lipid hypothesis, have succeeded in fooling the public. These two industries have spent tens of millions of dollars promoting and funding research designed to support the lipid hypothesis.
Many studies touting the evidence for the lipid hypothesis have recently been shown to be severely flawed. The few studies that do indicate a correlation between fat reduction and a decrease in coronary heart disease mortality also document a concurrent increase in deaths from cancer, brain hemorrhage, suicide and violent death. 
Says Anthony Colpo in “LDL Cholesterol: Bad Cholesterol, or Bad Science”: “The concept that LDL is ‘bad cholesterol’ is a simplistic and scientifically untenable hypothesis. Independent thinking practitioners must look at the readily available evidence for themselves, instead of relying on the continual stream of anti-cholesterol propaganda emanating from ‘health authorities.’ By doing so, they will quickly realize that the LDL hypothesis is aggressively promoted for reasons other than public health.” 
Some proponents of the lipid hypothesis argue that the incidence of cardiovascular disease is up because people are living longer than they did in the 1950s. Although it is true that more people reach old age today, the biggest reason for that is a drastic reduction in infant and childhood mortality rates. But the question is, are we really living that much longer?
Life Expectancy Statistics 
@ Birth # of years
At first glance these statistics seem to back what the proponents of the lipid hypothesis claim, we are in fact living longer. And since CVD is an elderly disease, one could deduce it is the reason the incidence is higher than it was 80 and even 50 years ago. The U. S. seems to be making very positive inroads to life expectancy, until you look at the big picture.
We know that 90% of all heart attacks occur over the age of 60. Let’s compare apples to apples and compare the life expectancy of people who reached 60 years of age in the same years as above.
@ 60 years of age # of years
If you reached 60 years of age in 1920, you could expect to live an average of 15.54 more years. If you reached 60 years of age in 1950, you were expected to live an average of 17.04 more years. If you reached 60 years of age in 2002 you were expected to live an average of 22 more years. From 1920, when CVD was virtually unheard of, to 1950 when CVD was becoming our number one killer, there was only a 1.5 year difference in life expectancy. And in more than eight decades from 1920 to 2002, with all the advances in medicine and the hundreds of billions spent on health care each year, we’ve only added 6.46 years.
I know what you’re thinking: “Mike is out of his mind! I can’t believe he is advocating cutting out polyunsaturated oils and hydrogenated oils while touting the benefits of saturated fats from animals and tropical oils.” The only claim that could be made against saturated fats is that they raise cholesterol levels. And for that claim to be negative, one has to believe higher cholesterol levels are a health risk. Well, as stated earlier, I do not believe this and Science
is on my side.
In a 1988 study to determine whether elevated serum cholesterol levels are associated with all cause mortality, mortality from coronary heart disease, hospitalization for acute myocardial infarction (heart attack), and unstable angina (acute chest pain with no relief from medication or rest, which is a strong predictor of heart attack), 997 subjects, all over the age of 70, were used to determine the ratios of the four-year incidence of all cause mortality. The results showed no support for the Lipid hypothesis. 
In a workshop held at the National Heart, Lung and Blood Institute, researchers looked at every study that had been published about the risk of having high or low cholesterol and came to the same conclusion: Mortality was higher for woman with low cholesterol than for woman with high cholesterol. 
Dr. Gilles Dagenais and associates concluded that high cholesterol levels are not associated with CVD in Canadian males. This conclusion was reached after having followed 5,000 healthy middle-aged men for more than 12 years. 
In Russia, low cholesterol levels were associated with an increased risk of heart disease. 
In a study published in the Journal of the American Medical Association, Harvard Medical School researchers examined the association between egg consumption and CVD in 37,851 male health professionals and 80,082 female nurses, and found low consumption at one egg per week and high at one or more eggs per day. Researchers also tracked the associated occurrence of heart attacks, stroke, and other types of cardiovascular disease in the male group for eight years and in the female group for 14 years. They found no connection between egg consumption and heart disease. Even after adjusting for factors such as age, weight, high-fat food intake, smoking, high blood pressure, and family history of heart problems, no statistical correlation was identifiable between egg eating and heart disease. Keep in mind eggs contain 200mg of cholesterol each. 
Why take statin drugs?
Thirty years ago you were considered hypercholesterolemia if you were a middle-aged man whose cholesterol was over 240 with other risk factors like smoking or obesity. At the National Institute of Health Consensus Development Conference in December of 1984, the parameters changed to men or women with levels above 200.  And a couple months ago I was told that doctors are considering 180 to be high and would like to see everybody around 170.  These recommendations are to the point of being unattainable by diet, exercise or any other lifestyle modification.
So-called experts are now recommending that anyone with high cholesterol be given drug therapy, mainly a family of drugs called statins. How convenient for pharmaceutical companies that the levels of cholesterol that are considered high has lowered. Lowering the standards for prescribing statins has literally been worth billions in sales.
Is there a conflict of interest? Major consumer groups think so. They found out that eight of the nine "experts" that made the recommendations were on the payroll of pharmaceutical companies that manufacture those drugs. Major scientific organizations have chastised medical journals for allowing the pharmaceutical industry to publish misleading results and half-truths. There is a major push under way to force the pharmaceutical industry (and others) to publish results of all of their studies, and not just the ones that appear positive. The studies that showed negative results would also be forced to be published. 
Some of the most common drugs to treat people with supposed high cholesterol levels are Lipitor, Zocor and Crestor. Formally referred to as HMG-CoA reductase inhibitors, these drugs (statins) work by inhibiting the enzyme HMG-CoA reductase. Inhibiting this enzyme does reduce cholesterol levels, but it also reduces the production of CoQ10 (Co-enzyme Q 10). CoQ10 is a vital component to all cells in our body and is a very powerful antioxidant (50 times stronger than vitamin E).
After age 20, our synthesis of CoQ10 starts to decline, with a fall strikingly after age 50. Combine our decreased ability to synthesize CoQ10 with statins and you have a recipe for disaster. Depletion of this essential enzyme can lead to fatigue, muscle soreness, muscle weakness and heart failure, which happen to be among the most common complaints of statin users. CoQ10 has been shown to be essential for a properly functioning heart as well as preventing heart disease and stroke. [30, 31]
Do statins even work in preventing death from CVD? Results from five large statin studies in January 2000 showed that total cholesterol of the more than 30,000 individuals tested was lowered by an average of 20.4%. However, the degree of cholesterol reduction had no association with lower incidence of CVD. If lowering cholesterol levels is so important in combating CVD, why didn’t people who saw the greatest reduction in cholesterol levels get more of a benefit from the drugs? This is a real case for lack of exposure response, which indicates that the factor under investigation is not the true cause, but is secondary to the real cause. 
An analysis of all the big statin studies reported before 2000 found that long-term use of the cholesterol-lowering drugs for prevention of CVD produced a 1% greater risk of death over 10 years compared to placebo groups. These findings serve as more than enough evidence to negate the use of statins for the purpose of lowering the mortality rate in patients with a CVD risk. 
Looking past the Lipid Hypothesis
At this point, I hope you agree that cholesterol doesn’t cause heart disease; at the very least, I hope I have at least got you thinking that it might not. Cholesterol is essential for life and without it our bodies could not function. It is the building block for many hormones, including testosterone, estrogen, DHEA, human growth hormone, T3 and T4 (thyroid hormones). Our brains are made of mostly cholesterol and saturated fat. Cholesterol is also used by the body for healing. This is the reason cholesterol is found in atheroma blockages: it’s trying to heal an injured area of an artery. So if not cholesterol, what causes heart disease?
One of the biggest contributors to disease is free radicals. These chemical marauders wreak havoc on whatever tissue is in their vicinity and are implicated in diseases ranging from CVD to cancer. Although they can be detrimental to our health, free radicals are normally found in conjunction with many functions of the body. For example, when we use fat or glucose for fuel, our mitochondria produce free radicals as byproducts. Our bodies are in a constant battle to keep free radicals under control. With every breath we take, our bodies work to keep a very destructive substance in check -- oxygen.
We can also ingest free radicals. One of the biggest sources of dietary free radicals is the refined unnatural oils you buy in the grocery store. Any oil that is not labeled “Cold Pressed,” “Expellar Pressed” or “Extra Virgin” is already rancid and loaded with free radicals. Another major source of dietary free radicals is hydrogenated oils. Read your food labels -- if it has “vegetable oil,” “hydrogenated vegetable oil,” “partially hydrogenated vegetable oil” or “shortening” listed as one of the ingredients, do not buy it. If you already have it, pitch it -- it’s garbage.
Free radicals, if not kept in check, can damage the inner lining (intima) of an artery, causing a lesion.
Many other substances have also been linked to arterial injury, including tobacco, high blood pressure, diabetes, trans fats, deficiencies in vitamins A and D, bacteria, viruses and more.
Injury causes inflammation and the body responds by producing raised plaques in an effort to heal the vascular lesions. This is known as the Response to Injury Hypothesis presented by Russell Ross and John Glomset in 1976.
Cardiovascular disease is recognized as having multiple causes, some known and some unknown. The lipid hypothesis hasn’t a leg to stand on. We know that saturated fat and cholesterol are healthy and essential for life. I hope this article has made you think. The oil and processed food industries are very powerful and are using all their resources to keep their products on the shelves with no regard for our safety or well being. But there are things we can do for ourselves and our families. Below are some guidelines we can follow to be healthier and reduce our risk of cardiovascular disease.
Read food labels.
Consume whole, unprocessed foods.
Don’t consume any product that contains trans fat.
Don’t be fooled by products that advertise “zero trans fat.” Always read the ingredient list and if “hydrogenated vegetable oil,” “partially hydrogenated vegetable oil” or “shortening” are listed, understand that it has trans fat. By law, companies can claim “zero” if there is .5 grams or less of trans fat per serving. There is no safe level of trans fat.
Don’t consume any product that contains vegetable oil, hydrogenated vegetable oil, partially hydrogenated vegetable oil or shortening listed as one of the ingredients.
Only use oils that are labeled “Cold Pressed,” “Expellar Pressed” or “Extra Virgin.”
Consume eggs laid by free range chickens. They are a good source of omega-3 fatty acids, biotin, and vitamins A, D and E.
Use peanut oil, sesame oil or olive oil for cooking if you do not want to use animal fats. These oils can also be used for one-time frying.
Use coconut oil for cooking or frying. It’s very stable, and has strong antimicrobial properties.
Use butter, not margarine.
Don’t use trans fat-free spreads. They are still made with highly processed oils that are rancid.
Keep your consumption of polyunsaturated fats to a minimum. They are high in omega-6 fatty acids.
Don’t eat like a vegetarian. We do not possess multiple stomachs, nor do we chew cud. Our stomachs produce hydrochloric acid, which is not found in herbivores. We are omnivores. There are essential nutrients in animal products that cannot be gotten in sufficient amounts by eating plants.
Don’t feed your children a low-fat diet. If they’re fat, it’s because they sit on their asses too much and eat too much junk. Not coincidentally, these are the same two reasons many adult Americans are overweight.
Supplement your diet with vitamins and other nutrients: A, D, E and C, CoQ10, fish oil (omega-3), selenium.
Exercise at least three days per week.
