What is cholesterol?

Cholesterol is a waxy substance that is often linked to soft candle wax. Cholesterol roles in the body are many. It is essential for the production of various hormones and vitamin D. There are two sources of cholesterol. One, your liver produces it. And second, animal-based food items like meat, poultry, and full-fat dairy products. These products are high in saturated and trans fats and that causes your liver to produce extra cholesterol. But, you do not necessarily need these products when it comes to aiding cholesterol production. Your body is capable of producing enough cholesterol that it needs and adding more to it will only take cholesterol levels in your body to unhealthy levels and it will start collecting in your arteries inviting many diseases.

Difference between good cholesterol and bad cholesterol?

When talking about cholesterol, two main types of cholesterol often comes up – good cholesterol and bad cholesterol. High-density lipoprotein (HDL), which is good cholesterol and low-density lipoprotein (LDL), which is bad cholesterol. Cholesterol moves in the body with the help of lipoproteins (made of fat and proteins). 

HDL helps in getting rid of the cholesterol from the body. It transports it to the liver to be expelled out so that there’s no excess cholesterol in the body and none of it gets collected in the arteries. And hence, HDL is called good cholesterol.

On the other hand, LDL takes cholesterol to your arteries. Too much cholesterol in arteries can lead to a buildup of plaque which can block your arteries in your heart and brain and you may suffer from a heart attack or stroke. Plaque buildup can also reduce the flow of oxygen to various organs which also becomes the cause for many diseases.
