Given the seriousness with which its talked about, you could be forgiven for thinking that all cholesterol is terrible and out to kill you.

The truth is, a healthy level of cholesterol is actually essential for your body to run properly every cell in your body contains some cholesterol. Your body uses cholesterol to build cell walls, make vitamin D and produce hormones. In fact, about 75% of the cholesterol in your body is made by your liver. The rest comes from some of the foods and drinks you consume.

Cholesterol can become a serious health problem when your body has too much of it, especially one type in particular called low-density lipoprotein or LDL cholesterol. Read on to find out what cholesterol is, the difference between good and bad cholesterol and how you can try to keep your cholesterol at a healthy level.

Safe Blood Cholesterol Levels

High Cholesterol, What Is Cholesterol  Everything We Need To Know About

Health authorities recommend that cholesterol levels should be no higher than 5.5 mmol per litre if there are no other risk factors present. If there are other cardiovascular risk factors such as smoking and high blood pressure or pre-existing cardiovascular disease, then the aim for the LDL levels would be less than 2 mmol/l. Approximately half of all adult Australians have a blood cholesterol level above 5 mmol/l. This makes high blood cholesterol a major health concern in Australia.

The Difference Between Good And Bad Cholesterol

If cholesterol is so necessary, why is it sometimes described as “bad” and at other times as “good?”

Your liver packages cholesterol into so-called lipoproteins, which are combinations of lipids and proteins. Lipoproteins operate like commuter buses that carry cholesterol, other lipids like triglycerides, fat-soluble vitamins, and other substances through the bloodstream to the cells that need them.

  • Low-density lipoproteins, sometimes called bad cholesterol, gets its bad reputation from the fact that high levels of it are associated with increasing your risk of heart disease. LDL contains more cholesterol than protein, making it lighter in weight. LDL travels through the bloodstream and carries cholesterol to cells that need it. When it becomes oxidized, LDL can promote inflammation and force lipids to accumulate on the walls of vessels in the heart and rest of the body, forming plaques. These plaques can thicken and may limit or completely block blood and nutrients to affected tissues or organs.
  • HDLor high-density lipoproteinsis also commonly referred to as “good cholesterol.” HDL is heavier than LDL because it contains more protein and less cholesterol. HDL gets its good reputation from the fact that it takes cholesterol from the cells and brings it to the liver. Having higher levels of HDL may also help lower your risk of developing cardiovascular disease.

Effects Of High Cholesterol Levels

The liver is the main processing centre for cholesterol and dietary fat. When we eat animal fats, the liver transports the fat, together with cholesterol in the form of lipoproteins, into our bloodstream.

Too much cholesterol circulating within LDL in our bloodstream leads to fatty deposits developing in the arteries. This causes the vessels to narrow and they can eventually become blocked. This can lead to heart disease and stroke.

Lifestyle Tips To Cut Cholesterol

Changing some of your lifestyle habits may also help to reduce your cholesterol and triglyceride levels. Suggestions include:

  • Cease alcohol consumption or reduce your alcohol intake to no more than one or two drinks a day. Avoid binge drinking. This may help lower your triglyceride levels.
  • Dont smoke. Smoking increases the ability of LDL cholesterol to get into artery cells and cause damage.
  • Exercise regularly . Exercise increases HDL levels while reducing LDL and triglyceride levels in the body.
  • Lose any excess body fat. Being overweight may contribute to raised blood triglyceride and LDL levels.
  • Control your blood sugar levels if you have diabetes. High blood sugars are linked to an increased risk of atherosclerosis , heart attacks and strokes.

  • “Cholesterol is used by the body as raw material for the healing process. This is the reason the injured areas in the arteries … have cholesterol along with several other components in the ‘scar’ tissue that is formed to heal the ‘wound’.”

  • Cholesterol often elevates as part of a protective immune system response to chronic infection.

  • Infants need plenty of cholesterol for proper brain development and cholesterol is normally found in large amounts in human breast milk.

  • Adrenal and gonadal hormones are made from cholesterol. These are the stress handling, energy producing and reproductive hormones.

  • Cholesterol is vital for proper nerve function. Three quarters of the myelin membrane is made from fat and of that nearly one quarter is cholesterol.

    If Cholesterol Is Important For Health Why Is It Good And Bad

    Lipoproteins have different concentrations of fat and transport cholesterol to different parts of the body. The lower the density of a lipoprotein, the more fat it contains. Therefore, LDL cholesterol is very rich in fat. LDL cholesterol delivers cholesterol to our cells and is associated with plaque build-up in our arteries which can lead to heart disease. HDL cholesterol, on the other hand, helps collects cholesterol from the blood stream and deliver it to the liver for excretion.

    With all of the bad publicity cholesterol gets, people are often surprised to learn that its actually necessary for our existence.

    Whats also surprising is that our bodies produce cholesterol naturally. But cholesterol is not all good, nor is it all bad its a complex topic and one worth knowing more about.

    Cholesterol is a substance made in the liver thats vital to human life. You can also get cholesterol through foods.

    Because plants cannot create it, you can only find it in animal products, like meat and dairy.

    In our bodies, cholesterol serves three main purposes:

  • It aids in the production of sex hormones.
  • Its a building block for human tissues.
  • It assists in bile production in the liver.

    Myth: All Cholesterol Is Bad For You

    What is Cholesterol?

    Fact: Some types of cholesterol are essential for good health. Your body needs cholesterol to perform important jobs, such as making hormones and building cells. Cholesterol travels through the blood on proteins called lipoproteins. Two types of lipoproteins carry cholesterol throughout the body:

    • LDL , sometimes called bad cholesterol, makes up most of your bodys cholesterol. High levels of LDL cholesterol raise your risk for heart disease and stroke.
    • HDL , or good cholesterol, carries cholesterol back to the liver. The liver then flushes it from the body. High levels of HDL cholesterol can lower your risk for heart disease and stroke.

    When your body has too much LDL cholesterol, it can build up in the walls of your blood vessels. This buildup is called plaque. As your blood vessels build up plaque over time, the insides of the vessels narrow. This narrowing can restrict and eventually block blood flow to and from your heart and other organs. When blood flow to the heart is blocked, it can cause angina or a heart attack.
