Cholesterol - What Should You Know?

For a long time, cholesterol in totality was seen as a bad thing for your body although the truth was a little more complicated than that. Cholesterol primarily is divided into two types, one of which can be categorized as bad cholesterol and the other as good cholesterol. Let's have an in-depth look at both the categories.

LDL or Low-Density Lipoprotein aka bad cholesterol - Cholesterol is a wax-like chemical which is found all over the body and it has important functions to perform. Cholesterol is carried all over the body by Lipoproteins. The low-density lipoproteins are denoted as bad cholesterol as they can accumulate on the walls of the blood vessels and cause blockages resulting in many ailments. LDL levels of 190 and above are considered dangerous. 

Some of the risks associated with it are:

1. Heart disease
2. Stroke
3. Atherosclerosis
4. peripheral artery disease among many others

HDL or High-Density Lipoprotein aka good cholesterol - This is a form of cholesterol which is usually desired in higher quantities as it removes LDL from the system by dislodging it from the arteries and then carrying it through the blood stream into the liver. The liver then breaks it down and removes it from the body. Thus, higher number of HDL cholesterol is always desirable. 
Some of the ideal numbers for HDL cholesterol within the body are:

Women - Ideal: 60 mg/dl, dangerous: 50 mg/dl or lower
Men - Ideal: 60 mg/dl, dangerous: 50 mg/dl lower

The role of triglycerides
Good and bad cholesterol levels also depend on the levels of triglycerides within the body and not just LDL or HDL cholesterol. Triglycerides are another type of fat which are used to store energy within the body but can also affect your health. It is most associated with atherosclerosis when the levels of triglycerides are high within the body. 

Some habits that contribute to high levels of it are

a. Lack of physical activity
b. Obesity or being overweight
c. Excesses in alcohol consumption
d. Smoking
e. Bad diet and others

Thus the good cholesterol versus bad cholesterol war also includes other factors, most of which can be easily changed by making subtle changes in life style and incorporating healthier habits. This will increase the good cholesterol and the other relevant elements and reduce the bad.
