Cholesterol is a type of fat found within the blood. The body makes cholesterol to supply the cell’s needs as cholesterol plays an important role in ensuring the functioning of the cell membrane; however we also ingest cholesterol from the food we eat. Elevated levels of cholesterol will have negative consequences as cholesterol will build up in your arteries. This is referred to as the hardening of the arteries. High levels of cholesterol will reduce the amount of blood, and therefore oxygen that is transported to all of our body tissues, including the heart. It is usually a slow process that gets worse over years of unhealthy eating. High cholesterol can lead to serious medical issues, including heart attacks and strokes.
