1. The function of Dietary Reference Intakes (DRIs) is to designate nutrient recommendations for:
- A. different ethnic groups.
- B. all individuals.
- C. most people.
- D. most healthy people.
Correct answer: D
Rationale: The correct answer is D. Dietary Reference Intakes (DRIs) are established to provide nutrient recommendations for most healthy people. They are not specific to different ethnic groups (choice A), all individuals (choice B), or most people (choice C). DRIs aim to prevent nutrient deficiencies and chronic diseases in healthy individuals by setting intake levels for various nutrients.
2. At what pH does the digestion of protein by pepsin in the stomach require?
- A. 1.8 and 3.5.
- B. 4.8 and 7.0.
- C. 6.8 and 8.5.
- D. 7.8 and 10.0.
Correct answer: A
Rationale: The correct answer is A: 1.8 and 3.5. Pepsin, an enzyme involved in protein digestion, functions optimally in an acidic environment, specifically between pH 1.8 and 3.5. This low pH is necessary for pepsin to break down proteins effectively. Choices B, C, and D are incorrect because pepsin requires a highly acidic environment, ruling out the pH ranges listed in those options.
3. The sugar to which all other sugars are converted during human metabolism is:
- A. sucrose
- B. fructose
- C. glucose
- D. maltose
Correct answer: C
Rationale: Glucose is the primary sugar used by the body for energy and is converted from other sugars during metabolism. Sucrose is a disaccharide composed of glucose and fructose, not the end product of sugar metabolism. Fructose is a simple sugar found in fruits but needs to be converted to glucose for cellular energy. Maltose is a disaccharide composed of two glucose units and is not the final product of sugar metabolism in humans.
4. Which of the following is an example of a complete protein?
- A. Milk
- B. Soy
- C. Sesame seeds
- D. Sweet potato
Correct answer: A
Rationale: The correct answer is A, Milk. Milk is considered a complete protein as it contains all the essential amino acids required by the body. Soy (choice B) is also a complete protein, containing all essential amino acids. Sesame seeds (choice C) and sweet potato (choice D) are not complete proteins as they lack one or more essential amino acids needed by the body.
5. Exchange Lists for Meal Planning was originally intended as a meal-planning tool for people who have:
- A. cancer.
- B. diabetes.
- C. hypertension.
- D. heart disease.
Correct answer: B
Rationale: The correct answer is B: diabetes. Exchange Lists for Meal Planning were originally created to assist individuals with diabetes in managing their diet by providing a structured approach to balanced food exchanges. This system helps individuals regulate their blood sugar levels and maintain overall health. Choices A, C, and D are incorrect because Exchange Lists for Meal Planning were not primarily developed for individuals with cancer, hypertension, or heart disease.
