About This Chapter
Lipids in Health and Nutrition - Chapter Summary
This chapter focuses on lipids (fats) and their role in health and nutrition. You will learn about the four classes of lipids and the role each plays in nutritional health. You'll find out about different food sources that provide lipids, and the recommended intakes for saturated fats, unsaturated fats, trans fats, cholesterol and essential fatty acids.
This chapter discusses the distinctions between fatty acids and triglycerides as well as the distinctions among saturated, monounsaturated and polyunsaturated fats in terms of structure and dietary sources. You'll learn about lipoproteins and how to classify them according to function. As the chapter progresses, you'll discover the effects of different fats, including omega 3 fatty acids, on cardiovascular health and disease. And the chapter will examine the relationship between lipids and obesity, and between lipids and various forms of cancer. After completing this chapter, you should be able to:
- Describe the four classes of lipids and the role and function of each in nutritional health
- Discuss food sources of lipids
- Outline recommended intakes for saturated fats, unsaturated fats, trans fats, cholesterol and essential fatty acids
- Name the classes of lipoproteins and classify them by function
- Explain health implications of various types of lipids
- Describe the relationship between lipids and obesity, lipids and cancer, and lipids and cardiovascular disease
These lessons will be taught via brief, engaging video lessons that streamline the learning process. You'll also find self-assessment quizzes and lesson transcripts to accompany each video. We give you key terms that are important for you to remember, and video tags that enable you to find the exact place in a video that you are looking for. And it has all been put together by experts in the field.
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
