Cholesterol is a fatty substance that is essential for the body. However, when there are high levels of it in blood it may be harmful. Because it adheres to the walls of arteries impeding the flow of blood. This may also lead to heart attack or stroke. 

To lower cholesterol levels in blood, you should reduce the consumption of animal fats especially those contained in red meat and eggs. 

Nutrition with antioxidants from supplements or plants lower the bad cholesterol (LDL), as they prevent the oxidation of good cholesterol (HDL). 

Eat plenty of fruits and vegetables.
