2 Cholesterol Lipid Component of cell membrane Found in the diet – Eggs, dairy, liver High levels lead to development of CHD 2 types of cholesterol -carrying proteins Low-density Lipoproteins (LDL) - bad cholesterol High-density Lipoproteins (HDL) - good cholesterol LDL- carries up to 70% Blood cholesterol from liver to body cells As level of LDL increase, Level of CHD increases HDL- carries 20% Blood cholesterol HDL- gathers Cholesterol for eliminartion As level of HDL Increase, risk of CHD decrease

3 Risk of developing CHD may be predicted by measuring the ratio of HDL to LDL in the blood High ratio indicates HDL level in high and LDL low = healthy Low ratio= high LDL= unhealthy Some evidence states that exercise can increase HDL levels A fingerprick test can measure plasma cholesterol levels, but analysis of the HDL:LDL ratio must be done in a lab.
