2. What is nutrition science?
Nutrition Science is the study of the effects of food components on the metabolism, health, performance and disease resistance of humans and animals. It also includes the study of human behaviors related to food choices.

3. Nutrients
The food you eat is a source of nutrients.
Nutrients keep your body functioning.

4. Your body needs nutrients to…
Work as a fuel/energy
Help you grow
Repair itself
Maintain basic bodily functions.

5. Balance is Key
For years, people held to the idea that there are “bad” nutrients and “good” nutrients when, in fact, all nutrients play a certain role in the body. Even those nutrients once considered “bad” such as fats and carbohydrates perform vital functions in the body and if one consumes too many “good” nutrients such as vitamins or minerals there can be harmful results, as well.

6. Balance - Eat foods from all of the food groups.
Variety - Eat different foods from each food group.
Moderation – Do not eat excessively from any group and portion size

7. The 6 Essential Nutrients
Water
Carbohydrates
Protein
Lipids (Fat)
Vitamins
Minerals

8. What is an Organic molecule?
Organic molecules contain Carbon
Organic molecules, substances that contain carbon-hydrogen bonds.

9. What is an Inorganic Molecule?
Molecules that DO NOT contain carbon.
DO NOT have carbon-hydrogen (C-H) bonds; generally they are simple and not normally found in living things.
Water & minerals are considered inorganic molecules

10. Monomers & Polymers
A monomer is a molecule that is able to bond in long chains. Here is a monomer:      Here is a polymer:
A large molecule made from many similar small molecules called subunits or monomers
In other words, Each MONOMER is a BUILDING BLOCK in the structure of a POLYMER

11. 3 major classes of organic compounds
Subunit/
Monomer
Polymer
Carbohydrates
Sugar
Mono-saccharide
Poly
saccharides
Lipids
Fatty acids
Proteins
Amino acids

12. Macronutrients vs. Micronutrients
Provide the body with energy
Are required in large amounts
Examples: Carbohydrates, lipids & proteins
Do NOT provide the body with energy
Are NOT required in large amounts
Examples: vitamins and minerals

13. Water
Although water does not provide the body with energy it is required in large amounts so it is in a category of its own.
