Describe America's changing fat intake over the past 50 years.
Discuss how fat intake is linked to risk of several chronic diseases.
List the functions of triglycerides and cholesterols.
Describe what factor determines how saturated a fat (or more correctly, a fatty acid) is.
Name several food sources of the following:
◦
saturated fatty acids
◦
monounsaturated fatty acids
◦
omega-3 polyunsaturated fatty acids
◦
omega-6 polyunsaturated fatty acids
Briefly describe how triglycerides are digested, absorbed and transported in the body.
Discuss the how fats in your diet relate to the different types of blood cholesterol
(otherwise known as blood lipids):
LDL, VLDL and HDL. How these types of blood lipids relate to your risk of heart disease.
List the functions of lipids in the body.
Briefly describe the relation of lipids to each of the following: cardiovascular disease,
cancer and obesity.
List the recommendations for the following:
◦
total fat
◦
saturated fat
◦
omega-3 polyunsaturated fat (also known as linolenic acid)
◦
omega-6 polyunsaturated fat (otherwise known as linoleic acid)
