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. Vitamins We Need: Their Importance & Sources
There are a lot of different vitamins, and they come from many different places! This lesson will teach you about what they are, how many different kinds you need, what they do, and where you can obtain them naturally.
6. Minerals in Our Food: Functions in the Body & Food Sources
Minerals are important substances that help your body's form and function on many different levels. This lesson will go over some important ones, what they do, and where they are found in our diets.
7. Making Healthy Nutritional Choices: Habits, Behaviors & Resources
This lesson will help you see how easy it is to track what you eat and change your diet for the better. It will also provide you with additional information on where a wealth of information on healthy nutrition can be found.
8. The Benefits of Regular Physical Activity: Mental Health, Stress & Life Span
The mind and body can greatly benefit from even 30 minutes of exercise a day. Find out exactly what impact regular exercise can have on your mind, body, and lifespan in this video lesson.
9. What is Iodine? - Uses, Sources, Benefits & Deficiency Symptoms
In this lesson, we will learn about iodine. We will learn how we get it in the diet, why it is important to the body, and what happens if we do not get enough iodine in our diets.
10. Glycogen: Definition, Storage & Breakdown
Carbohydrates are an important energy source for the human body. Yet, when we consume too much of this fuel, we have to have a way to store the excess, as you'll find out in this lesson.
11. Lipid Bilayer: Definition, Structure & Function
The lipid bilayer is important for maintaining the shape of a cell and for selective permeability. Therefore, it is vital for the survival and function of the cell. This article explains what the lipid bilayer is and how its structure contributes to cell viability.
12. What Are Fats? - Functions & Molecular Structure
There are probably many images that come to mind when you hear the word 'fat.' This lesson is all about fat and will explore the structure and function of this often misunderstood lipid.
13. What Are Nutrients? - Definition & Examples
This lesson is about nutrients, which are the building blocks of all living organisms. This lesson will explain what nutrients are, the different kinds of nutrients and offer examples of each.
14. What is Cholesterol? - Definition & Overview
In this lesson we will discuss cholesterol and learn what it does do our bodies, both positively and negatively. Read about the sources, uses, and dangers of cholesterol, and then test your knowledge with a short quiz.
