1. An example of government nutrition policy is:
- A. MyPlate Food Guidance System.
- B. Dietary Guidelines for Americans 2010.
- C. Healthy People 2020.
- D. Dietary Reference Intakes (DRIs).
Correct answer: C
Rationale: The correct answer is C: Healthy People 2020. Healthy People 2020 is a government initiative that sets goals for improving the health of Americans, including specific nutritional objectives. Choices A, B, and D are not examples of government nutrition policies. MyPlate Food Guidance System is a visual tool to help individuals make healthy food choices, Dietary Guidelines for Americans 2010 provide evidence-based advice for Americans two years and older, and Dietary Reference Intakes (DRIs) are a set of nutrient reference values.
2. What is the basis of MyPlate food guidance?
- A. Percentage of calories from each macronutrient.
- B. Exchange Lists for Meal Planning.
- C. Appropriate amounts of food from each food group.
- D. Amounts of macronutrients and micronutrients.
Correct answer: C
Rationale: The correct answer is C: 'Appropriate amounts of food from each food group.' MyPlate food guidance focuses on portion sizes from different food groups to promote a balanced diet. Choices A, B, and D are incorrect because MyPlate emphasizes the consumption of a variety of foods from different food groups rather than focusing solely on macronutrient percentages, exchange lists, or specific nutrient amounts.
3. Which nutrient has a protein-sparing effect?
- A. Glycerol
- B. Carbohydrate
- C. Nitrogen
- D. Fatty acids
Correct answer: B
Rationale: Carbohydrates have a protein-sparing effect, meaning that adequate carbohydrate intake can prevent the use of protein for energy. Glycerol, nitrogen, and fatty acids do not have a protein-sparing effect. Glycerol is a component of fats and oils, nitrogen is a component of proteins, and fatty acids are used primarily as an energy source.
4. The hormone secretin stimulates production of a buffering solution for the duodenum by the:
- A. stomach.
- B. liver.
- C. pancreas.
- D. oxyntic cells.
Correct answer: C
Rationale: The correct answer is C: pancreas. Secretin stimulates the pancreas to release bicarbonate, which acts as a buffering solution to neutralize the acid entering the duodenum from the stomach. This process helps in maintaining the pH balance in the small intestine. Choice A, stomach, is incorrect as the stomach does not produce the buffering solution needed for the duodenum. Choice B, liver, is incorrect because secretin does not directly stimulate the liver to produce a buffering solution. Choice D, oxyntic cells, is also incorrect as these cells in the stomach are responsible for producing gastric acid, not the buffering solution needed in the duodenum.
5. A major focus of the 2010 Dietary Guidelines is:
- A. generally healthy segments of the population
- B. the unhealthy American public
- C. vulnerable population segments
- D. ethnically diverse eating styles
Correct answer: B
Rationale: The correct answer is B: the unhealthy American public. The 2010 Dietary Guidelines primarily aimed to address the unhealthy eating habits prevalent in the American population. Choice A is incorrect as the focus was not solely on generally healthy segments of the population. Choice C is incorrect as the guidelines were not specifically tailored only for vulnerable population segments. Choice D is incorrect as the guidelines were more concerned with promoting healthy eating habits rather than ethnically diverse eating styles.
