Catalyst, a "solid" science program on Australian television, sent the day before Episode 1 of "Heart of the Matter ', a series that critically explores the health advice of the past 50 years in relation to cardiovascular disease. It is a familiar story, but because here more and more paleo-naive people with peep and I just do not have time to make a real post, I show him here. For gentlemen who now know the story behind the cholesterol myth: the appearance of filmmaker Dr. Maryanne Demasi makes up for it. For the ladies, there are unfortunately only balding old men. This is also a good occasion for a bit to stabbing an ancient lesson 'cholesterol.
Plus a very special way of advertising by the Swiss bank Credit Suisse! Why would alert a bank against the dangers of the current sugar consumption?
The promised (and this time short) lesson 'cholesterol'
Wat is cholesterol?
Cholesterol is a peculiar molecule. It is often 'scolded' for fat or lipide', but is in fact an alcohol, although it behaves differently. You will be definitely not drunk. The complicated three-dimensional structure of hydrogen and carbon atoms is not soluble in water. All organisms make diligent use of that property. They build cholesterol in their cell walls. They are therefore 'watertight', so that the processes can not be disturbed in the cell by the surrounding bedlam. Cholesterol is especially important for the proper functioning of nerve cells. Hence, the majority of the cholesterol is concentrated in the brains and the rest of the nervous system. Many cholesterol is required for the production of vital hormones. Because cholesterol does not dissolve in water - and thus not in blood - it is wrapped up by the liver in packets of fat (lipid) and protein (proteins), called lipoproteins. Like tiny submarines which carrylipoproteins among others, cholesterol and vitamin D from and to the places where it is needed.
What do the lipoproteins?
The best known are Low Density Lipoprotein (LDL) and High Density Lipoprotein (HDL). The terms store the density of the packages. Both are vital. They provide the transport of cholesterol by the body. LDL is the courier that brings cholesterol from the liver to the tissues. HDL carries excess cholesterol from the tissues back to the liver.
But LDL is still 'bad'?
Several large studies have shown that people who have a relatively large LDL and / or relatively low HDL are at increased risk of getting a heart attack. And the more HDL relative to LDL, the lower the risk. However, this has not been shown that cholesterol packets are the cause of the problem. A lot of things that are known to be bad for the blood vessels, also accompanied by changes in the ratio of cholesterol: smoking, weight gain, chronic stress, high blood pressure, lack of exercise and decreased sensitivity to the blood sugar-regulating hormone insulin. More and more scientists believe that an 'unfavorable' cholesterol is merely a symptom of something kwalijkers. Cholesterol designate as a scapegoat, according to arrest them as stupid as firefighters because they are often spotted at the scene of a fire. Moreover, the relationship between heart disease and cholesterol is not nearly as convincing as that between light and thepresence of firefighters. The English example, have exactly the same cholesterol levels as the French, but get more than five times as many heart attacks. People in Lithuania have a much lower LDL than peers in Sweden, but a four times higher risk of stroke. Also strange: only about 30 percent of Dutch people who suffer heart attacks have abnormal cholesterol levels.
What is cholesterol?
Cholesterol is only found in animal products such as meat, fish, shellfish, eggs and dairy.
What can I do to get my cholesterol down?
All the things that have proven to be good for the heart - quit smoking, lose weight, reduce stress - also appear to lead to 'beautiful' cholesterol levels. The common factor is according to the latest findings of the sensitivity of the cells to the hormone insulin. The better these cells respond to insulin, the less of this hormone have to make your body and how healthy you are. One of the best things you can do to optimize your insulin sensitivity is to get out of your armchair. This has far-reaching consequences. A striking example: participants of the Vasaloppet, a ninety kilometer long Swedish cross-country event that requires a formidable preparation, have regardless of age, gender and income group much less likely to die than ordinary citizens within a decade. "In part based on self-selection," Bahman Farahmand, epidemiologist at the Karolinska Institute in Stockholm says, and discoverer of theso-called "Vasaloppet effect '. "Healthy people are more inclined to exercise intensively. There hardly sit among smokers. But the bulk of the protective effect is directly attributable to the frequent train. "The last time diving more and more studies showing that it is never too late to start moving intensively. Daily half hour sturdy running, cycling, swimming or skating, for example after a short time a beneficial effect on coronary arteries that supply blood to heart muscle. That proved cardiologist Rainer Hambrecht Heart Center of the University of Leipzig in a study two years ago a lot of dust kicked up. Hambrecht left ten included cardiac patients with malfunctioning coronary an hour quite bikes daily (until the pain threshold) on the hospital exercise bike. After a month showed the blood flow to be greatly improved in the coronary arteries of these "bike patients. So strong that a doctor noheart disease when they might discover. The condition of the coronary arteries of nine medical comparable control subjects who had not been trained, was unchanged bad. Hambrecht also found that solid training arteriosclerosis against going into the coronary arteries. At low intensity exercise (walking daily) atherosclerosis continued. At a moderate intensity (jogging daily) stopped growing, and at a high intensity (daily running) the arteriosclerosis was even less.
Is it wise to go low-fat food for a 'nice' cholesterol?
Helps extra linoleic acid against high cholesterol?
Yes. That is to say, the daily use of which gives rise to what the figures down. Robust consumption not only decreases as 'unfavorable' labeled LDL, but also as 'favorable' HDL identified. Moreover, it worsens the more important relationship between the many different cholesterol fractions. Generous use of linoleic acid may be less good for heart and blood vessels than industry and health authorities have promised us for forty years. "Numerous studies show that a lot of linoleic acid in the diet disrupts the delicate balance and that actually contributes to the development of heart disease, diabetes, arthritis and cancer," says the Japanese fatty expert Dr. Harumi Okuyama. Okuyama and colleagues advise their countrymen not to make the same mistake as to leave the west and linoleic acid enriched margarines.
Is it true that bad cholesterol-lowering drugs for you?
On that last word has not been spoken yet. Statins inhibit the body's production of cholesterol, but also the production of a number of other vital substances. Manufacturers call statins the safest drugs ever developed. Many users and independent experts are less euphoric. Fact: statins reduce the risk of heart attacks in middle-aged men. The effect (300 men have to swallow a long years in order to postpone the first infarction) can not be attributed to the cholesterol-lowering, because men with a very low cholesterol enjoy exactly the same protection as men with high values. More and more scientists also attribute the effect of statins to effects that have nothing to do with cholesterol reduction. Statins ensure for instance that any constrictions are becoming more complex in the vessel wall and less likely to break. Such a "bursting" narrowing is one of the main causes of amyocardial infarction. They also promote the creation of a vaatwerwijdende fabric. And finally, they have anti-inflammatory properties. What conceal the manufacturers, is that statins have never saved a woman's life, while large studies reveal this "sideshow" yet again and again. Across from the modest protective effect in men is an unpleasant and unpredictable side effects profile: fatigue and forgetfulness to severe muscle pain. Not everyone will suffer from a statin, but the American doctor Beatrice Golomb wrote recently in Geriatric Times that particular confusion and memory loss occur significantly more often than most doctors think. A physically active life and statin use inconvenient go together, is indisputable. Swiss researchers found that athletes this medication by definition poorly tolerated. All their sport subjects developed within a short time exercise intolerance, muscle pain, muscle damage orchronic tendinitis. Whether or not swallowing a statin is a matter of carefully weigh. Discuss it with your doctor or specialist.
Are you fat cholesterol?
On the contrary. Most foods contain a lot of cholesterol, contain much protein. Protein gives faster and feel full longer than carbohydrates and fat. Eating cholesterol-rich foods you will help to consume fewer calories. And with that you fight at the core of many problems: pathological insulin resistance. Cholesterol itself performs as said important functions in every cell of the body and especially in the brains, but supplies no energy.
