1. The percentage of the total daily caloric intake for healthy persons that should be supplied by carbohydrate is:

• A. 10% to 35%.
• B. 20% to 35%.
• C. 40% to 55%.
• D. 45% to 65%.

Correct answer: D

Rationale: The correct answer is D: 45% to 65%. Carbohydrates should contribute between 45% to 65% of the total daily caloric intake for healthy individuals to maintain a balanced diet. Choices A, B, and C are incorrect because they suggest lower ranges, which may not provide sufficient energy from carbohydrates for overall health and well-being.

2. Foodborne illness may be caused by contamination of food with:

• A. pesticides.
• B. genetically modified ingredients.
• C. microorganisms.
• D. food additives.

Correct answer: C

Rationale: The correct answer is C: microorganisms. Microorganisms, such as bacteria and viruses, are common causes of foodborne illnesses. These pathogens can contaminate food during various stages of production, processing, or preparation. Choice A, pesticides, are chemicals used to control pests and are not a common cause of foodborne illnesses. Genetically modified ingredients, choice B, refer to foods derived from genetically modified organisms (GMOs) and are not inherently linked to foodborne illnesses. Food additives, choice D, are substances added to food to preserve flavor or enhance taste and are not typically the primary cause of foodborne illnesses.

3. What is a primary function of macronutrients in the body?

• A. Regulate metabolic processes.
• B. Supply energy.
• C. Maintain homeostasis.
• D. Control cellular activity.

Correct answer: B

Rationale: The correct answer is B: Supply energy. The primary function of macronutrients such as carbohydrates, fats, and proteins is to supply energy for various bodily functions. Choices A, C, and D are incorrect because while regulating metabolic processes, maintaining homeostasis, and controlling cellular activity are essential functions in the body, they are not the primary roles of macronutrients. Macronutrients mainly serve as a source of energy to support daily activities and bodily functions.

4. Which of the following foods is high in indispensable amino acids?

• A. Lentils
• B. Tofu
• C. Peanuts
• D. Eggs

Correct answer: D

Rationale: The correct answer is D, eggs. Eggs are considered a high-quality protein source as they are rich in indispensable amino acids. Lentils, tofu, and peanuts also contain protein but are not as high in indispensable amino acids as eggs, making them less complete protein sources.

5. 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.
