1. Define Nutrition Is the study of food and the nutrients we need to sustain life and reproduce. Also,
examines the way food nourishes the body and affects health.
2. Define Nutrient Compounds in foods that sustain body processes.
3. Six Classes of Nu- Carbohydrates, fats (lipids), proteins, vitamins, minerals and water.
trients
4. Define Organic Describing compounds that contain carbon or carbon- bonds.
5. Define Inorganic Describing compounds that do not contain carbon.
6. Essential Nutri- Must come from foods because either they cannot be made by the body, or they
ents cannot be made in sufficient amounts to meet the body's needs and support
health.
7. Nonessential Nu- Can be made in sufficient quantities in the body to meet the body's requirements
trients and support health. Example: Vitamin D (Synthesized in the skin upon exposure to
sunlight).
8. Conditionally Es- When nonessential nutrients become essential.
sential
9. Adenosine A compound that is broken down to produce energy for working muscles and other
triphosphate tissues.
(ATP)
10. Energy-yielding The three nutrients that provide energy to the body to fuel physiological functions:
nutrients and Carbohydrates, lipids and protein.
what are the
three?
11. kilocalorie The term used by scientists to quantify the amount of energy found in food.

1 degree centigrade; used to express the measurement of energy in foods; 1
kilocalorie is equal to 1,000 calories.
12. Macronutrients Organic nutrients, including the energy-containing carbohydrates, lipids, proteins,
and water that the body needs in large amounts.
13. Micronutrients Essential nutrients the body needs in smaller amounts: vitamins and minerals.
14. Enzymes Proteins in living cells that act as catalysts and control chemical reactions.
15. coenzymes Substances, such as vitamins or minerals, that facilitate the activity of enzymes.
16. Solubility The ability to dissolve into another substance.
17. Water- Soluble Vi- Vitamins that dissolve in water, they generally cannot be stored in the body and
tamins must be consumed.
18. Fat-Soluble Vita- Vitamins that dissolve in fat and be stored in the body.

19. Major Minerals Minerals found in the body in amount greater than 5 grams, also referred to as
(Macro) macrominerals.
20. Trace Minerals Minerals found in the body in amount less than 5 grams, also referred to as
(Micro) microminerals.
21. Consensus Agreed-upon conclusion of a group of experts based on a collection of information.
22. Scientific Method A process used by scientists to gather and test information for the sake of gener-
