1. Most fat replacers are made from:

• A. proteins.
• B. carbohydrates.
• C. cholesterol.
• D. monoglycerides.

Correct answer: B

Rationale: Most fat replacers are made from carbohydrates. Carbohydrates are utilized to mimic the texture of fats in food products. Proteins (Choice A) are not commonly used as fat replacers and are more often associated with other functions in food. Cholesterol (Choice C) is a type of fat and not used to replace fat in food products. Monoglycerides (Choice D) are sometimes used as emulsifiers or stabilizers in food products but are not the primary source of fat replacers.

2. What is the primary function of carbohydrates as a food source?

• A. Regulate metabolic processes.
• B. Build body tissue.
• C. Supply energy.
• D. Provide bulk.

Correct answer: C

Rationale: The primary function of carbohydrates as a food source is to supply energy. Carbohydrates are the body's main source of energy, providing fuel for various physiological functions. Choice A is incorrect because carbohydrates do not primarily regulate metabolic processes; that role is mainly attributed to enzymes and hormones. Choice B is incorrect because proteins are primarily responsible for building body tissue. Choice D is incorrect because fiber, not all carbohydrates, provides bulk in the diet.

3. 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.

• A. Peristalsis.
• B. Segmentation.
• C. Metabolism.
• D. Mastication.

Correct answer: D

Rationale: The correct answer is D, 'Mastication.' Mastication is the mechanical process of chewing that breaks down food into smaller particles. Peristalsis (choice A) is the involuntary constriction and relaxation of muscles in the gastrointestinal tract that moves food along. Segmentation (choice B) is the mixing movement of the digestive system that helps to break down food and mix it with digestive juices. Metabolism (choice C) refers to the chemical processes that occur within a living organism to maintain life.

5. 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.
