1. Which monosaccharide only occurs naturally in foods in combination with another sugar as a disaccharide?

• A. Fructose.
• B. Galactose.
• C. Sucrose.
• D. Maltose.

Correct answer: B

Rationale: The correct answer is B, galactose. Galactose naturally occurs in foods only when it is combined with glucose to form lactose, a disaccharide found in milk. Fructose is a monosaccharide found in fruits and honey. Sucrose is a disaccharide composed of glucose and fructose, commonly known as table sugar. Maltose is a disaccharide formed by the combination of two glucose molecules.

2. The nutrients involved in metabolic regulation and control include minerals, vitamins, and:

• A. amino acids.
• B. carbohydrates.
• C. fats.
• D. water.

Correct answer: D

Rationale: The correct answer is D, water. Water plays a crucial role in metabolic regulation along with vitamins and minerals. While amino acids, carbohydrates, and fats are essential nutrients for various bodily functions, they are not primarily involved in metabolic regulation and control.

3. Which of the following provides the best source of nutrients?

• A. specific food combinations.
• B. a variety of foods.
• C. individual foods.
• D. a variety of food supplements.

Correct answer: B

Rationale: A variety of foods is the best source of nutrients because it ensures a balanced intake of all essential nutrients required by the body. Option A, specific food combinations, may not provide all necessary nutrients as relying on only a few types of food may lead to deficiencies. Option C, individual foods, also may not provide a complete range of nutrients necessary for overall health. Option D, a variety of food supplements, is not the best source of nutrients as whole foods are generally more beneficial due to their natural nutrient composition and bioavailability.

4. After ingested food is mixed and churned with gastric secretions, the resulting semifluid mass is called:

• A. a bolus.
• B. chyme.
• C. rennin.
• D. glycogen.

Correct answer: B

Rationale: The correct answer is B: chyme. Chyme is the partially digested food that forms a semifluid mass after mixing with gastric juices. A is incorrect because a bolus refers to a rounded mass of food ready to be swallowed. C, rennin, is an enzyme involved in the digestion of milk proteins and not the term for the semifluid mass after food mixing with gastric secretions. D, glycogen, is a form of stored glucose in the body and is not the term used to describe the partially digested food mass in the stomach.

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.
