Cholesterol is a fat like substance required by the body for many functions including:
Productions of cell walls and hormones
Digestion of fats
Production of nerves
There are 2 types of cholesterol obtained by our bodies:
Blood cholesterol - Produced naturally in the liver
Dietary cholesterol - Consumed from foods of animal origin
Although required by our bodies, excessive blood cholesterol levels may cause narrowing or blockage of blood vessels leading to heart disease or stroke.
High blood cholesterol is typically a result of either genetics or lifestyle factors. It may be possible to lower your cholesterol levels by up to 30% by making healthy diet and lifestyle changes.
