LDL Cholesterol - known as "bad" cholesterol
LDL Cholesterol is known as "bad" cholesterol - it's important to reduce this as much as possible.
LDL carries cholesterol from the liver to the rest of the body. When the level of LDL cholesterol in our blood is too high, the excess cholesterol can slowly accumulate in the walls of our arteries, making them narrower and less elastic. Over time this increases the risk of a heart attack or stroke.
Along with other risk factors, our LDL cholesterol level can be used to predict the risk of developing cardiovascular diseases. It is agreed by experts that levels of LDL cholesterol should be kept as low as possible.
HDL Cholesterol - known as "good" cholesterol
HDL cholesterol is known as "good" cholesterol - it performs useful functions to protect your heart.
HDL cholesterol is like a hard-working cleaner. It picks up cholesterol from the walls of our arteries and carries it back to the liver. Because it manages the bad (LDL) cholesterol, HDL cholesterol is considered to protect you from cardiovascular diseases. That's how we know that this "good" cholesterol is so valuable.
Total Cholesterol - the measure of all cholesterol in the blood
Total cholesterol is a measure of all cholesterol in the blood, mainly LDL cholesterol and HDL cholesterol.
The level of total cholesterol is often used to estimate our risk of cardiovascular disease. Experts now understand, however, that the LDL cholesterol level is much more informative when it comes to estimating your risk.
Triglycerides - energy sources and transporters of fat around the body
Triglycerides play an important role as energy sources and transporters of fat around the body.
Most fats found in food and in the body are in the form of triglycerides. Blood triglycerides either come from the fats in our food or they are formed in the body from other nutrients like sugars. An elevated level of triglyceride in the blood is associated with cardiovascular diseases, which is why its level should be kept low.
