Understanding Cholesterol…

What is Cholesterol?
Do you know what it is?
Have you ever stopped and wonder how many foods you eat each day that contains this molecule?

Well I am using this video to help you my viewers to understand more about this molecule.
Cholesterol is a waxy, fat like substance found in the blood stream and cells of the body. This naturally occurring substance plays a critical role in the formation of cell membranes and the manufacture of hormones. only a small amount of functions is needed to carry out these functions so the presence of additional cholesterol poses a risk to the body.

How cholesterol works?
This molecule does not dissolve in the blood stream but is transferred in and out of the cell by carriers called low density lipoproteins (LDL) and high density lipoproteins (HDL). When cholesterol increases more lipoproteins is needed to be produced to transfer it across the cell. LDLs are bad because too much of it result in plaque build up in the artery wall which leads to a condition know as atherosclerosis. The arteries are hardened and clogged which can lead to a heart attack or stroke. On the other hand HDL is a good carrier since it aids in the removal of cholesterol from the arteries into the liver and out of the body.

How is cholesterol determined in the body?
A blood test can be done. The levels of cholesterol varies in a person’s age, weight and sex.
An LDL level above 160 is high while an HDL level below 40 is too low. This places someone at risk for plaque build up. 75% of the cholesterol is made in the body while the other 25% is obtained from our diet. It is found in foods such as meat, eggs and liver. Eating less saturated fats from animals is a first step in lowering cholesterol levels and living a healthy life style.

This video was beneficial in helping me understand more about the effects cholesterol. A possible way to better this video is maybe the additional of more pictures to show the effects this molecule has on our body. I enjoyed it sice it was short and to the point.

Enjoy!!!
