Heart disease is an umbrella term for a number of different diseases affecting the heart. As of 2007, it is the leading cause of death in the United States, England, Canada and Wales, killing one person every 34 seconds in the United States alone.
The blood vessels consist of arteries, arterioles, capillaries, venules, and veins. All blood is carried in these vessels. The arteries, which are strong, flexible, and resilient, carry blood away from the heart and bear the highest blood pressures. Because arteries are elastic, they narrow (recoil) passively when the heart is relaxing between beats and thus help maintain blood pressure. The arteries branch into smaller and smaller vessels, eventually becoming very small vessels called arterioles. Arteries and arterioles have muscular walls that can adjust their diameter to increase or decrease blood flow to a particular part of the body.

How to Have Healthy and Normal Cholesterol Levels?  

Much has been written in recent years through the blood-cholesterol levels. Not all that long ago, it was thought that eating food with high cholesterol levels have caused a high level of cholesterol in the blood, and this in turn could lead to heart disease, myocardial infarction, heart and other related problems. And because of these beliefs and fears that people were encouraged to eat foods low in fat super.

The problem that philosophy and teaching is that it is a little too general and broad. There are types of fat, which is good for you. In fact, these so-called "good fats" are essential for the proper nutrition and health. There are also "bad fats" However, this may be a factor for the health and heart problems.

cholesterol in the blood have a similar distinction. Where once it was of the view that you need to have your cholesterol levels below a certain figure - as 200mg - now it is clear, through scientific studies and research that this is not always a good yardstick. Instead there are "good" and "bad" cholesterol. And these figures are what is important, together with the ratio of one to another.

LDL cholesterol is considered the "bad" kind, and that stands for low-density lipoprotein. Without a lot of medical and scientific terminology, let's suffice to say that LDL-cholesterol, this may lead to negative reactions in the human body. In contrast, there is HDL or high-density lipoprotein, which creates favorable responses in the human body.

If you find it hard to remember which one aims to improve and what not, think of LDL-cholesterol than the ones you want to keep low - use the L at the beginning as a memory trigger - and HDL is the You want to keep higher (H = higher). The relationship between LDL and HDL cholesterol is also important.

test is now unfortunately a bit vague. In some cases, medical professionals are still a common cholesterol test that gives you the total amount. It is increasingly common, but at least an estimate of LDL to HDL cholesterol ratio or in total to HDL cholesterol levels, but both are estimates rather than actual measurements.

Some say that LDL level should be at or below 100 mg, while the more recent recommendations call less than 70mg. For total cholesterol to HDL, it is such a 5:1 ratio or less is best.

Now you can get cholesterol from food. Primary sources of cholesterol from animal products like eggs, peanuts, linseed, and beef. Some cholesterol are found in plants as well, but there is usually a much smaller amount. Most people assume - and books to teach himself - that there is no cholesterol in plants at all. However, this is a misunderstanding, because the U.S. FDA does not require that it be on food labels if there are less than 2 mg per serving.

Please note that eating foods containing cholesterol does not mean they automatically cholesterol health problems. Some of these problems can be - or at least contributed to - by poor eating habits are generally poor exercise, and genetics.

cholesterol can be hereditary. How many health problems today, it's been noted that some genetic background, have much higher risks for certain health problems than others.
