7 Lessons in Chapter 1: Introduction to Nutrition
What is Nutrition?

1. What is Nutrition?

Nutrition is the process of taking in nutrients from the foods you eat. Learn about the six nutrients needed for energy, maintenance of tissues and regulation of bodily processes: carbohydrates, fats, proteins, water, vitamins and minerals.

Energy-Yielding Nutrients: Carbohydrates, Fat & Protein

2. Energy-Yielding Nutrients: Carbohydrates, Fat & Protein

Carbohydrates, fats and proteins are referred to as the three energy-yielding nutrients because they provide your body with energy that is measured in calories. You'll also learn about another substance that can provide your body with calories, even though it is not a nutrient.

Organic vs Inorganic Nutrients: Differences & Importance

3. Organic vs Inorganic Nutrients: Differences & Importance

The presence or absence of carbon is what differentiates organic nutrients from inorganic nutrients. Carbohydrates, lipids, proteins and vitamins have carbon in their structure, making them organic. Water and minerals do not, so they are inorganic.

Using the Scientific Method in the Nutrition Field

4. Using the Scientific Method in the Nutrition Field

The scientific method is a systematic process that scientists follow to provide reliable nutritional advice to the public. Learn how a hypothesis is formulated and how this leads to the creation of a theory, as well as what makes a study reliable, in this lesson.

Dietary Reference Intakes: EAR, RDA, AI & UL

5. Dietary Reference Intakes: EAR, RDA, AI & UL

Dietary Reference Intakes (DRIs) are a set of values used to plan a healthy diet. Learn about the DRI values: Estimated Average Requirements (EARs), Recommended Dietary Allowances (RDAs), Adequate Intakes (AIs) and Tolerable Upper Intake Levels (ULs).

Assessing Your Nutrition, Diet & Health: How to Avoid Disease

6. Assessing Your Nutrition, Diet & Health: How to Avoid Disease

A nutritional assessment is used to determine the nutritional status of a person or group of people. Learn about the ABCDs of nutritional assessment: anthropometric assessment, biochemical assessment, clinical assessment and dietary assessment.

How to Find Sources of Reliable Nutrition Information

7. How to Find Sources of Reliable Nutrition Information

There is a lot of nutritional information available through the Internet and other media outlets, so how do you find reliable sources of nutritional information? Follow along to find out and learn how to protect yourself from false claims.
