Cholesterol
Lipid Component of cellmembrane
Found in the diet –Eggs, dairy, liver
High levels lead to development of CHD
2 types of cholesterol-carrying proteins
Low-densityLipoproteins (LDL) - bad cholesterol
High-densityLipoproteins (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 HDLIncrease, risk of CHD decrease
• 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.
