Cholesterol has long been an obsession for many people. For the purpose of learning more about cholesterol, distinguishing the difference between good cholesterol and bad cholesterol, please refer to the article below.

Cholesterol is an essential fat that the cells in our body need. Cholesterol comes from two sources, one is made in the liver, the other is absorbed from food, and cholesterol is not entirely harmful.
Cholesterol is transported in the blood by lipoproteins - transport mediators. Therefore, there are two concepts, which are LDL cholesterol and HDL cholesterol:
LDL cholesterol (low density lipoprotein cholesterol): low density lipoprotein cholesterol HDL cholesterol (high density lipoprotein cholesterol): high density lipoprotein cholesterol.

The basic difference between HDL cholesterol and LDL cholesterol is: HDL cholesterol is "good cholesterol", and LDL cholesterol is "bad cholesterol".
HDL cholesterol accounts for about 1/4 - 1/3 of the total cholesterol in the blood, is considered good because it transports cholesterol from the blood to the liver, transports cholesterol away from plaque, thus, reducing the risk of atherosclerosis arterial and other serious cardiovascular events.
LDL cholesterol is a "bad" component of cholesterol, when LDL cholesterol increases a lot in the blood, it leads to deposition in the walls of blood vessels, causing plaque. Atherosclerotic plaque gradually narrows or occludes blood vessels, leading to life-threatening diseases such as myocardial infarction, stroke,...

HDL cholesterol is good cholesterol, so the higher the blood concentration, the better, the optimal value is > 60 mg/dL.
LDL cholesterol is bad cholesterol, so it should be limited to low levels in the blood, the optimal value is less than 100 mg/dL.

LDL cholesterol can increase due to factors related to diet, bad habits like smoking, sedentary, or related to diseases like hypertension, diabetes...
HDL Lower cholesterol can be caused by smoking, overweight, obesity, ... Therefore, to increase HDL cholesterol, it is necessary to quit smoking, maintain a reasonable weight, increase physical exercise...
