Nutrition Exam 1 Questions With
Complete Solutions
/. What is nutrition? - Answer-✅the science that studies food and how food nourishes
our bodies and influences our health
/.Why is nutrition important? - Answer-✅gives you energy, lowers the risk of chronic
diseases, prevents nutrient deficiencies, "you are what you eat"
/.What are the 6 classes of nutrients essential to health? - Answer-✅Carbohydrates
(energy providing)
Fats or lipids (energy providing)
Proteins (energy providing)
Vitamins (non-energy providing)
Minerals (non-energy providing)
Water (non-energy providing)
/.What are the macronutrients and are they needed in large or small amounts? -
Answer-✅carbs, fats, and proteins- large amounts
/.What are carbs? - Answer-✅the primary source of fuel for our bodies. Made up of
carbon, hydrogen, and oxygen.
/.What are fats? - Answer-✅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
providing more energy (fuel).
/.What are proteins? - Answer-✅support tissue growth, repair, and maintenance. We
break down dietary proteins 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.
/.What are vitamins? - Answer-✅build and maintain bones, muscles, blood, immune
system, and ensure healthy vision.
Assist with releasing and using the energy found in all 3 macronutrients
/.What are minerals? - Answer-✅not broken down during digestion, not destroyed by
heat or light, and maintains their structure (calcium)
/.Dietary Reference Intake (DRI) for most nutrients: - Answer-✅EAR - estimated
average requirement
RDA - recommended dietary allowance
, AI - adequate intake
/.Dietary Reference Intake (DRI) for energy and macronutrients: - Answer-✅EER -
estimated energy requirement
AMDR - acceptable macronutrient distribution range
/.What are the four steps of the scientific method? - Answer-✅Observations
Hypothesis
Experiment
Data support / does not support hypothesis
/.What is an adequate diet? - Answer-✅enough energy, nutrients, and fiber
/.What is a moderate diet? - Answer-✅eating the right amount of food to maintain
healthy weight
/.What is a balanced diet? - Answer-✅combination of foods that provide proper
proportions of nutrients
/.What is a varied diet? - Answer-✅eating a lot of different foods each day
/.What are the 5 components that must be listed on food labels? - Answer-✅Statement
of Identity
Net contents of package (wt., volume, or numerical count)
Ingredient list - listed in descending order by weight
Name and address of food manufacturer, packer, or distributor
Nutrition information - Nutrition Facts Panel
/.Dietary Guidelines for Americans 2010 emphasize 3 major goals for Americans: -
Answer-✅Balance calories with physical activity to manage weight
Consume more of certain foods and nutrients such as fruits, vegetables, whole grains,
fat-free and low-fat dairy products, and seafood
Consume fewer foods with sodium, saturated fats, trans fate, cholesterol, added sugars,
and refined grains
/.What is appetite? - Answer-✅psychological desire to consume specific foods
/.What is hunger? - Answer-✅physiologic sensation that prompts us to eat
/.Define satiety: - Answer-✅feeling of being full
/.Define hormones: - Answer-✅• Chemicals produced in specialized glands that travel in
the bloodstream to target organs in other parts of the body
/.Define chime: - Answer-✅semifluid mass consisting partially digested food, water &
gastric juices
