heart disease and cholesterol

What is Cholesterol? Cholesterol helps your body build new cells, insulate nerves, and produce hormones. Normally, the liver makes all the cholesterol the body needs. But cholesterol also enters your body from food, such as animal-based foods like milk, eggs, and meat. Too much cholesterol in your body is a risk factor for heart disease.

What Are the Symptoms of High Cholesterol? High cholesterol itself does not cause any symptoms, so many people are unaware that their cholesterol levels are too high. Therefore, it is important to find out what your cholesterol numbers are. Lowering cholesterol levels that are too high lessens the risk for developing heart disease and reduces the chance of a heart attack or dying of heart disease, even if you already have it.

How Does High Cholesterol Cause Heart Disease? When there is too much cholesterol in your blood, it builds up in the walls of your arteries, causing a process called atherosclerosis, a form of heart disease. The arteries become narrowed and blood flow to the heart muscle is slowed down or blocked. The blood carries oxygen to the heart, and if not enough blood and oxygen reach your heart, you may suffer chest pain. If the blood supply to a portion of the heart is completely cut off by a blockage, the result is a heart attack.

There are two forms of cholesterol that many people are familiar with: Low-density lipoprotein (LDL or “bad” cholesterol) and high-density lipoprotein (HDL or “good” cholesterol.) These are the form in which cholesterol travels in the blood.

LDL is the main source of artery-clogging plaque. HDL actually works to clear cholesterol from the blood.

Triglycerides are another fat in our bloodstream. Research is now showing that high levels of triglycerides may also be linked to heart disease.

Cholesterol Linked to Heart Disease ?

    I’ve heard that smoking causes heart disease. I understand lung cancer is caused by mutations the genetic code of structures such as the alveoli, but I’m not too clear on how smoking may contribute to heart disease. Of course, as a stimulant that taxes the heart and lungs, nicotine may not exactly be the most healthful thing affecting the cardiovascular system, but no one blames caffeine for their cardiovascular maladies. What’s the deal with smokes and heart disease?

  2. Any info on Cardiometabolic Disease, Cardiovascular Disease, Diabetes Mellitus, Heart Disease, Insulin Resistance, and Metabolic Syndrome. Wondering about there effects and how they relate to Atherosclerosis and Thrombosis.

    Thank you for any information.

  3. pasteurized milk i mean

  4. Wonder if fluoride in water, toothpaste etc could be a factor since it it inhibits enzyme function even in very small amounts.

    I agree BimLanders, I think if more people were aware of what causes heart disease and how to prevent it some lives may be saved. I’ve always believed that Omega 3 is extremely important for heart health and overall well being. I would encourage anyone suffering from cholesterol to take them! I know many people around me have recommended Neurovi,com due to the enhanced ratio of DHA to EPA, even over the popular GNC brand.

    Please note that no one suffers from cholesterol, which is essential to health.
    Blaming cholesterol for disease is like blaming blue flashing lights for blocking motorways.
    Association does not prove causality.

    I have already suffered 2 heart attack & have what my phsyican calls dangerously high triglycerides & LDL, and i was told that if i do not get these levels under control i will have another. This did frighten me and i knew i needed to do something to reverse this damage. I knew plant sterols were powerful so i tried Sterolyn, and i’m very proud to say that my triglycerides have gone from 512 all the way down to 155. LDL count down from 240 to 132. Great product.

    The major avoidable contributory factor to cardio-vascular disease is a sudden fall in blood glucose concentration
    A notion supported by the fact that Diabetics, who apparently suffer from repetitive, abnormally rapid, falls in blood glucose concentration, are documented with an above average incidence of cardio-vascular disease.
    The cause of the injury that plaque repairs and the cause of a sudden seizure is common.

  10. i am studing nutrition at uni. and we are being taught that excess unhealthy fat intake and general unheathy lifestyle choices (lack of exercise etc) causes cardiovasuclar disease. But then I read about this “cholesterol myth” in a book, and now my life is confused.

  11. glynwainwright says:

    Question what you are told.
    Do your own research checks on PubMed
    The world is run by Pharmaceutical interests who do not want their customers to fix their lifestyles.
    Be a skeptic! Be your own person!
    Cholesterol is innocent.
    Do be confuse statistical association with causality.
    Otherwise you may conclude that arriving in hospital (statistically) makes you very sick!

    especially if you arrive by ambulance

    What about the cholesterol level of the US? I understand that there is no correlation between good cholesterol and heart disease… b/c France, etc… they eat and drink things that have high cholesterol levels that are good for you… like olive oil, balsamic viniger, red wine etc… but I have a hard time believing that something like a cheese burger and diet pepsi life style is heart attack free… and I think it’s interesting that the US or even North America was not put on the test.

  14. norwaydbp says:

    The french eat more saturated fat than we do.
    The masai in africa took more than half their calories from saturated fat (butter) and through autopsy were shown to have zero incidence of heart disease.
    The Tokelau of New Zealand area ate a diet with more than 35% saturated fat from fish and coconut, and had absolutely no incidence of heart disease until they emigrated to mainland new zealand and were introduced to sugar.
    Read “Good Calories, Bad Calories” or “Vegetarian Myth” for proof!

  15. Fatdissolver says:

    While nutrition labels usually combine them, the saturated fatty acids appear in different proportions among food groups. Lauric and myristic acid radicals are most commonly found in “tropical” oils (e.g. palm kernel, coconut) and dairy products. The saturated fat in meat, eggs, chocolate, and nuts is primarily the triglycerides of palmitic and stearic acid. Epidemiological studies of heart disease have implicated the four major saturated fatty acids to varying degrees.

  16. Fatdissolver says:

    The World Health Organization has determined that there is “convincing” evidence that myristic and palmitic acid intake increases the probability, “possible” risk from lauric acid, and no increased risk at all from stearic acid consumption. And it cannot possibly be denied that the portions of a typical American diet is by far larger then any other country, and rich in myristic and palmitic acid.

  17. Fatdissolver says:

    The French diet consists of significantly less sugar than the American diet. The French eat pastries, but the pastries are more buttery than sugary. Sugar is an addictive substance when it is refined and consumed in large quantities. Obviously, some sugar is good for us. But this sugar needs to come from fruits and vegetables. Over consumption of sugar leads to increased weight, which is linked to increased heart disease.

  18. Fatdissolver says:

    Anthocyanins are flavonoids known as polyphenols that pack a powerful punch through antioxidants. Anthocyanins are found in copious quantities in red grapes. Thus, red wine provides the French with a protection against heart disease, even though the typical French diet is high in saturated fat.

  19. norwaydbp says:

    Thanks for taking your time to share this information.

    The evidence that the WHO offers is, at best, epidemiological and correlative, but has never been proven to be causative, ever. I think there is more evidence to support the notion that saturated fat in general is, if anything, protective.

  20. norwaydbp says:

    I base these conclusions on many many studies:See the Framingham or Nurses studies, which attempted to show fat/cholesterol as potentially dangerous and instead showed strong correlations between increased sat fat/cholesterol consumption and the reduced risk of disease/all-cause mortality. All I can do is consider the evidence, and draw my own conclusions. To date, all the evidence indicates to me that animal fats are good for us, and refined grains and sugars are not. Thanks again Fat-dissolver

  21. bigmouthbob says:

    I lowered my LDL by increasing saturated fat (including red meat) and lowering whole grains. Much to the chagrin of the PA. I pointed out he also thought “global warming” was something real.

  22. ThemisMusicToronto says:

    If cholesterol is good for you, why is there such a prevalent and widely circulated belief that cholesterol is bad and causes heart deisease? I don’t understand. Is there a conspiracy with some gain to an entity? Otherwise, why would the general belief against Cholesterol exist?

  23. glynwainwright says:

    Good question – the answer is in the power struggle between Ancel keys and the AHA in the 50s/60s. We now have a 30 billion dollar industry betting that cholesterol suddenly after millions of years of evolution became a disease producing substance. It was by asking questions about how that switch could happen I found out the wonderful trth about cholesterol and the commercial/politcal/health errors that panicked the US government to condemn cholesterol and fat.

  24. glynwainwright says:

    This week the american journal of clinical nutrition has published a paper declaring saturated fats to be innocent of causing heart disease – and pointing the finger at the substances that replaced it in our food. It is all clear if you read the basic biology of what cholesterol and fat does in our bodies. Pass the butter please.
    Full fat milk is a whole food for rearing mammals. Eggs contain everything you need to make a healthy chick! Beware of processed food and pharmacy industries.

  25. glynwainwright says:

    LDL chiolesterol has a vital job to do for our immune systems and myelin production in neurons. Hope you haven’t caused any problems by lowering LDL. Send your doctor back to study Biochem 101.
    See above comment on cholesterol evolution.

  26. could anybody please point me how to get the original data from monica, framingham, etc?

    I keep seeing amazing claims like this, which, if true, would put the lipid hypothesis immediately to rest. Yet, I cannot see the original data if I look for them in the WHO – monica web page.
