1. Simple & Complex Carbohydrates: Dietary Needs
This lesson will explore the many different kinds of carbohydrates found in food. You'll learn about monosaccharides, disaccharides, polysaccharides, and much more!
2. Insoluble and Soluble Fiber: Dietary Needs
If you didn't know this already, there are many different kinds and functions of fiber! You'll learn about what dietary, functional, total, soluble, and insoluble fiber is and how much you need each day and why.
3. Proteins & Amino Acids: Importance & Dietary Needs
Can protein become fat? How much protein do we need? What's the difference between an essential and a complete protein? You'll find out that and much more as we go over the nutritional aspects of proteins.
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. Biological Fitness: Definition & Concept
In everyday life, the term 'fitness' is used in relation to exercise, diet, and overall well-being. In biology, it refers less to how healthy an individual is, and more to the number of babies he or she makes. Find out more in this lesson.
10. What is BMI? - Definition, Formula & Calculation
In this lesson, the term body mass index (BMI) will be defined, and we'll explore the formula to calculate a person's BMI. Several different examples can assist you in learning this concept. Finally, a few examples of how to use BMI in the health care world will be described.
11. What is Potassium? - Definition, Sources, Benefits & Side Effects
We need nutrients for our body to be healthy and to function well. One of the essential nutrients we need is potassium. Continue reading to find out where can we get potassium and why it is so essential to our bodies.
12. What Are Amino Acids? - Definition & Structure
Your body cannot function without proteins, and in order to build all these important proteins, your body needs amino acids. In this lesson, learn what amino acids are and what they look like. Then, test your new knowledge with a short quiz.
13. What Are Trans Fats? - Definition, Sources & Examples
The majority of trans fats are artificial fats created by adding hydrogen to liquid vegetable oil to make it into a solid. Once found in many different foods, the use of trans fats has been drastically reduced. Learn more about these fats and take a quiz at the end.
14. What is Fatty Acid? - Composition & Structure
Fatty acids are key components of triglycerides, which we use to store energy in our bodies. This lesson discusses the important characteristics of these acids in the human body.
