Cholesterol

Definition:

Cholesterol is a waxy, fat-like substance found in all cells of the human body. It’s essential for building healthy cells, producing hormones, and creating vitamin D.^[1] But while it is essential, too much LDL cholesterol can be harmful.

That’s because high levels of ‘bad’ LDL cholesterol can build up in your arteries, increasing the risk of heart disease and stroke. HDL cholesterol, on the other hand, is known as ‘good’ cholesterol, because it helps remove LDL cholesterol from your arteries.

Your cholesterol levels can be affected by your diet (foods high in saturated and trans fats can raise LDL ‘bad’ cholesterol), your lifestyle (regular exercise and maintaining a healthy weight can help lower LDL cholesterol), and genetics (some people inherit a predisposition to high cholesterol). ^[1]
