1. What is nutrition? the science that studies food and how food nourishes our bodies and influ-
ences our health
2. Why is nutrition im- gives you energy, lowers the risk of chronic diseases, prevents nutrient defi-
portant? ciencies, "you are what you eat"
3. What are the 6 class- Carbohydrates (energy providing)
es of nutrients es- Fats or lipids (energy providing)
sential to health? Proteins (energy providing)
Vitamins (non-energy providing)
Minerals (non-energy providing)
Water (non-energy providing)
4. What are the carbs, fats, and proteins- large amounts
macronutrients and
are they needed
in large or small
amounts?
5. What are carbs? the primary source of fuel for our bodies. Made up of carbon, hydrogen, and
oxygen.
6. What are fats? an important source of energy for our bodies at rest and during low intensity
exercise. Made up of carbon, hydrogen, and oxygen as well, but much less
oxygen and water than carbs so they pack together more densely thus pro-
viding more energy (fuel).
7. What are proteins? support tissue growth, repair, and maintenance. We break down dietary pro-
teins into amino acids and reassemble them to build our own body proteins.
Proteins can provide energy but are NOT a primary source of energy. Made
up of carbon, hydrogen, oxygen, and nitrogen.
8. What are vitamins?

build and maintain bones, muscles, blood, immune system, and ensure
healthy vision.
Assist with releasing and using the energy found in all 3 macronutrients
9. What are minerals? not broken down during digestion, not destroyed by heat or light, and main-
tains their structure (calcium)
10. Dietary Reference EAR - estimated average requirement
Intake (DRI) for most RDA - recommended dietary allowance
nutrients: AI - adequate intake
11. Dietary Reference EER - estimated energy requirement
Intake (DRI) for en- AMDR - acceptable macronutrient distribution range
ergy and macronu-
trients:
12. What are the four Observations
steps of the scientif- Hypothesis
ic method? Experiment
Data support / does not support hypothesis
13. What is an adequate enough energy, nutrients, and fiber
diet?
14. What is a moderate eating the right amount of food to maintain healthy weight
diet?
15. What is a balanced combination of foods that provide proper proportions of nutrients
diet?
16. What is a varied eating a lot of different foods each day
diet?
