Identify the ways that nutrition affects health. (1) - Answer --prevents disease
-eating habits have a role in determining our level of health
Identify the six major nutrients, their roles in the body, and the calorie values of the
three macronutrients and alcohol. (3) - Answer -The six major nutrients are:
1. Carbohydrates - 4 kcal/gram
2. Lipids (fats or oils). - 9 kcal/gram
3. Protein - 4 kcal/gram
4. Vitamins - 0 kcal/gram
5. Minerals - 0 kcal/gram
6. Water - 0 kcal/gram
Alcohol: 7 kcal/gram
Describe the scientific method, identify research terms and study designs, and interpret
research findings. (4)
What is the scientific method? - Answer -1. Make observations
2. Form hypotheses
3. Review current scientific literature
4. Design studies, conduct tests, collect data
5. Analyze data and draw conclusions
6. Report findings
7. Conduct more research to confirm/refute findings
Describe the scientific method, identify research terms and study designs, and interpret
research findings. (4)
What is a randomized controlled trial? - Answer --double-blind and placebo controlled
-results by comparing the experimental group to the control group
Describe the scientific method, identify research terms and study designs, and interpret
research findings. (4)
What is a cohort study? - Answer -Looking at large groups of people and seeing their
risk factors for disease.
-prospective or retrospective
Describe the scientific method, identify research terms and study designs, and interpret
research findings. (4)
What is a case-control study?
What is a cross-sectional study?
, What is a case report? - Answer -A case-control study compares those with a disease
to those who do not have the disease.
A cross-sectional study looks at data from a population group at one point in time.
A case report are descriptive studies based on uncontrolled observations of patients.
Describe the scientific method, identify research terms and study designs, and interpret
research findings. (4)
What is an animal experiment? - Answer -A study using animals.
Use conversion equivalents. (3) - Answer -1 cup = 8 fluid ounces
4 cups = 1 quart (qt)
1 gallon = 16 c or 4 q
3 teaspoons =1 tablespoon
4 tablespoons = ¼ cup
1 Liter = 1000 ml
16 ounces = 1 pound
2.2 pounds = 1 kilogram
1 in = 2.54 cm
1 gram =1000 milligrams = 1,000,000 micrograms
Define the principles of a healthy eating pattern including nutrient density, variety, and
portion sizes. (2) - Answer -Nutrient density: a comparison of a food's nutrition content
to its calorie content.
-Nutrient density = Amt. Of nutrients per serving / Amt. Of calories per serving
Eating a variety of foods is best because all foods offer different nutrients that can help
you meet your daily needs.
Portion size: the amount of food you eat in one sitting. (serving size is the
recommended amount)
Identify the purposes of the Dietary Guidelines for Americans (DGA) and the benefits of
following these recommendations. (1) - Answer -The purpose of the dgas is provide
science-based advice on what to eat and drink to promote health, reduce risk of chronic
disease, and meet nutrient needs.
Benefits of following recommendations:
-support a healthy weight
-avoid disease
-eat more nutrient dense foods
Classify foods into myplate Food Groups and compare the major nutrient contributions
across food groups. (10 matching) - Answer -Five food groups:
