Cholesterol is a waxy substance that is found in all the cells of our body and it looks like fat. Cholesterol is necessary since it helps our body to produce hormones that, consecutively, promotes a better digestion of food and also vitamin D.
On the other hand, it should be noted that the body itself produces the necessary cholesterol and there are many foods that contain this substance.
If you have high blood cholesterol, it can stick to other substances in your blood to form plaque. This is dangerous because it sticks to the walls of your blood vessels, producing a disease called arteriosclerosis, narrowing of the coronary arteries and many more.
