About This Chapter

Watch online video lessons and learn about fatty acids and triglycerides, cardiovascular disease, lipoproteins and much more. Each lesson is accompanied by a short multiple-choice quiz you can use to check your understanding of these nutrition topics.

Lipids in Nutrition - Chapter Summary and Learning Objectives

This chapter focuses on the role that lipids play in nutritional health. The health professionals who lead these lessons will discuss saturated, monounsaturated and polyunsaturated fats and unveil the different classes of lipoproteins. You'll watch lessons on omega-3 fatty acids and food sources for lipids, while getting a firsthand look at factors that lead to cardiovascular disease. This chapter can help you understand the following:

  • Structure of lipids
  • Food sources for fatty acids
  • Suggested intakes
  • Connection between lipids and obesity and cancer
  • Cardiovascular disease types

10 Lessons in Chapter 9: Lipids in Nutrition
Structure and Function of Lipids

1. Structure and Function of Lipids

Molecules called lipids have long hydrocarbon chains that determine the way they act. They can be fats, oils, or hormones, and even exist in our cell membranes. Learn more about the chemical structure and biological function of various lipids in this lesson.

Lipids: Types & Nutritional Role

2. Lipids: Types & Nutritional Role

There are different types of lipids, and each one plays a role in your health. Learn how triglycerides, phospholipids and steroids differ in their chemical structure and the jobs they do within your body.

Saturated, Monounsaturated & Polyunsaturated Fat: Dietary Needs

3. Saturated, Monounsaturated & Polyunsaturated Fat: Dietary Needs

Fat has been derided as being really bad for you despite serving many important functions. You'll learn about these functions and the different kinds of fat you may encounter as well as why a lot of fat can truly, in the end, be bad for you.

Lipoproteins: Classes & Functions

4. Lipoproteins: Classes & Functions

Lipoproteins transport fats through your blood. Learn about the different classes of lipoproteins: chylomicrons, very low density lipoproteins (VLDLs), low density lipoproteins (LDLs) and high density lipoproteins (HDLs) and their jobs in this lesson.

Foods That Are Sources of Lipids

5. Foods That Are Sources of Lipids

Fats add flavor to the foods you love. Yet, eating too many unhealthy fats, such as saturated fats, trans fats and cholesterol, can lead to health problems. Learn which foods contain these unhealthy fats and which ones contain fats that promote health in this lesson.

Recommended Dietary Intakes of Lipids

6. Recommended Dietary Intakes of Lipids

Fats add a lot to the enjoyment of your daily diet, but too much of the wrong fats can lead to health problems. In this lesson, learn about the different types of fats that you consume throughout your day and the recommended amounts you should eat.

Health Effects Associated with Lipids

7. Health Effects Associated with Lipids

Lipids, or fats, are important nutrients that your body needs for proper functioning. But eating too many fats, especially the unhealthy fats, such as saturated fats and trans fats can lead to heart disease, cancer and obesity.

Cardiovascular Disease Risk Factors & Preventative Strategies

8. Cardiovascular Disease Risk Factors & Preventative Strategies

This lesson will describe for you the numerous controllable and uncontrollable risk factors associated with cardiovascular disease as well as important preventative strategies to maximize your health.

Different Kinds of Cardiovascular Disease: Definitions & Examples

9. Different Kinds of Cardiovascular Disease: Definitions & Examples

So many problems can occur in the cardiovascular system of your body. Some of them mainly involve the heart and others the blood vessels, but one big one involves both at the same time!

Diagnosing and Treating Cardiovascular Disease

10. Diagnosing and Treating Cardiovascular Disease

This lesson will describe the many different ways cardiovascular diseases can be diagnosed and treated. For example, you'll learn the differences between angioplasty and angiography.
