Cholesterol for many years was a Synonym for “cardiac risk”. Then, researchers discovered that there are “evil” and “good” cholesterol. To its positive effect on heart and blood vessels, a US study now doubts.
High cholesterol levels were considered long years as one of the most important risk factors for heart attack and stroke. Because the blood fat can be deposited on the inner walls of the blood vessels and constrict blood flow to the heart life-threatening disturbed.
Most of the circulating cholesterol is a major component of cell walls, the body forms itself. One part comes from animal foods. In order to reduce a high cholesterol level, should be Concerned with values above 200 milligrams per deciliter of blood in Butter, and especially eggs – the yolk contains the highest amount of Cholesterol of any food.
Level of cholesterol does not depend on the egg consumption
Since then, experts argue again and again, how many eggs a day are allowed – the number varies depending on the study between 1 and 4. But the thing with cholesterol is much more complicated, not to exceed a value of 200 in the so-called “total cholesterol”. And the risk for heart and blood vessels depends on the least of the ate the eggs amount.
How much cholesterol is allowed to circulate in the blood depends on age, gender and risk factors for cardiovascular disease. Most important, its composition in so-called HDL – and LDL-cholesterol, however, is: In combination with lipoproteins of low density, also called LDL deposits cholesterol on the walls of blood vessels. Lipoproteins with high density, HDL, transport cholesterol from the blood and prevent hardening of the arteries.
Important is the composition of cholesterol is
As a science, had recognized that only a part of the Blutfetts is dangerous, another part of the heart and blood vessels, protects, however, were patients and Doctors easier: The “good” HDL cholesterol, the “bad” LDL-cholesterol to the cell walls of the blood vessels can get stuck and clogged. Henceforth respected physician, especially on a high proportion of HDL (High Density Lipoprotein) cholesterol in their patients. How much LDL or HDL circulates in the blood, however, is primarily genetically determined.
In healthy people, HDL should be over-proportion of under 40 mg/dl, the LDL-share may be up to 160 mg/dl. Desirable less than 115 mg/dl “bad” cholesterol, out of a total however, a maximum value of 200 mg/dl.
Patients with heart disease should not have more than 70 mg/dl bad cholesterol, and a total value of less than 150 mg/dl.
Also a lot of “good” cholesterol is bad for the heart
Now an American study has scratches but the Image of the “good” cholesterol. The cardiologist Marc Allard-Ratick of Emory University in Atlanta found that from a concentration of 60 milligrams per deciliter of blood increases the risk for “cardiovascular events”. This is Not to say that only a company who has too little, but too much HDL cholesterol in the blood, suffers increasingly deadly strokes and heart attacks.
The result of the U.S. scientists, presented at the European society of cardiology Congress, held at the end of August in Munich. Allard-Ratick had studied the data of 5,000 women and men who were at the beginning of the study, on average, 63 years old, and the majority of a heart problem.
Mean cholesterol values are at the healthiest
They were divided on the Basis of the HDL-cholesterol values in five groups between under 30 and over 60 mg/dl. After four years, 13 percent of the subjects had died due to a heart attack or other cardiovascular causes.
The lowest risk of death had patients, with values between 41 and 60 mg/dl. At an HDL concentration below 40 mg/dl, the risk of death was higher, at values of 60 mg/dl, it rose by almost 50 percent. The link remained even when other heart risks, such as Smoking, Diabetes, or LDL-values and other influencing factors have been taken into account in the cholesterol levels.

Concentrated levels of HDL cholesterol loses its ability to fat away
Why the HDL-cholesterol is losing at a very high concentration of its protective function, is unclear and has yet to be explored. A presumption is that faulty HDL particles. You will not be able to fulfil their task, and fats out of the blood away.
Study Director Allard-Ratick says: “Maybe it’s time to change our perspective on HDL-cholesterol. Doctors tell their patients so far, ‘The more HDL, the better’. However, the result of this study suggests that the is preserved.“
