High blood cholesterol increases the risk of CVD
Includes:
-cholesterol
-high density and low density lipoproteins
-saturated and polysaturated fats

- HIGH BLOOD CHOLESTEROL INCREASES THE RISK OF CVD
- Cholesterol is a lipid
- Needed for the body to function normally
- Cholesterol needs to attach to a protein to move around the body = LIPOPROTEIN
- TWO TYPES OF LIPOPROTEINS
- HIGH DENSITY LIPOPROTEIN (HDL)
- Mainly made out of protein
- Transport cholesterol from body tissues to the liver (excreted/recycled)
- Function; reduce blood cholesterol when the level is too high
- LOW DENSITY LIPOPROTEIN (LDL)
- Mainly lipid
- Transport cholesterol from the liver to the blood where they circulate until they are needed by cells
- Function; increase blood cholesterol when level is too low
- HIGH DENSITY LIPOPROTEIN (HDL)
- High total blood cholesterol level & high LDL level = increase risk of CVD
- Diet in high saturated fat raises LDL level
- More cholesterol is transported to the blood
- Increases total blood cholesterol & increases the risk of CVD
- More cholesterol is transported to the blood
- Diet in high saturated fat raises LDL level
- Diet high in polyunsaturated fat raises HDL level
- Cholesterol is transported from the blood to the liver
- Decreases total blood cholesterol and decreases the risk of CVD
- Cholesterol is transported from the blood to the liver
- Cholesterol is a lipid
