Nutrition Final Exam Quizlet

1. What term describes foods that contain non-nutrient substances whose known action in the body is to promote well-being to a greater extent than that contributed by the food's nutrients?

A. fortified foods
B. enriched foods
C. functional foods
D. health-enhancing foods

Correct answer: C

Rationale: Functional foods are specifically designed to promote health benefits beyond basic nutrition. Fortified foods (choice A) are those with added nutrients that are not originally present, enriched foods (choice B) have nutrients added back that were lost during processing, and health-enhancing foods (choice D) is a vague and less specific term compared to functional foods.

2. What type of nutrient is needed by the body and must be supplied by foods?

A. nutraceutical
B. metabolic nutrient
C. organic nutrient
D. essential nutrient

Correct answer: D

Rationale: The correct answer is D, essential nutrient. Essential nutrients are substances that the body needs for normal functioning but cannot produce in sufficient amounts, so they must be obtained through the diet. Nutraceuticals (choice A) are products derived from food sources that are purported to provide extra health benefits beyond basic nutrition. Metabolic nutrients (choice B) and organic nutrients (choice C) are not standard terms used to describe nutrients needed by the body. Therefore, choices A, B, and C are incorrect.

3. Which measure best describes the amounts of nutrients that should be consumed by the population?

A. The Dietary Reference Intakes, as they provide a set of nutrient intake values for healthy people in the United States and Canada
B. The Tolerable Upper Intake levels, as they indicate the maximum daily amount of a nutrient considered safe for most healthy people
C. The Estimated Average Requirements, as they reflect the average daily amount of a nutrient needed to maintain a specific function in half of the healthy individuals of a population
D. The Recommended Dietary Allowances, as they represent the average daily amount of a nutrient considered adequate to meet the known nutrient needs of practically all healthy individuals

Correct answer: D

Rationale: The Recommended Dietary Allowances (RDAs) are the best measure to describe the amounts of nutrients that should be consumed by the population. RDAs represent the average daily intake level that meets the nutrient requirements of nearly all (97-98%) healthy individuals in a particular life stage and gender group. Choice A, the Dietary Reference Intakes, provide a set of nutrient intake values but do not specifically address the average daily amount of a nutrient considered adequate for practically all individuals. Choice B, the Tolerable Upper Intake levels, focus on the maximum daily amount of a nutrient deemed safe for most healthy people, not the average daily amount needed. Choice C, the Estimated Average Requirements, reflect the average daily amount of a nutrient needed by half of the healthy individuals, which is not as comprehensive as the RDAs that cater to nearly all healthy people.

4. What is an important dietary consideration for a child with cystic fibrosis?

A. High-calorie, high-fat diet
B. Low-sugar diet
C. Increased dietary fiber
D. High-sodium diet

Correct answer: A

Rationale: For a child with cystic fibrosis, an important dietary consideration is a high-calorie, high-fat diet. This type of diet helps address malabsorption issues commonly seen in individuals with cystic fibrosis and supports adequate growth and development. High-calorie, high-fat foods are recommended to help meet the increased energy needs of these individuals. Choices B, C, and D are not the most appropriate dietary considerations for a child with cystic fibrosis. A low-sugar diet may not provide enough calories for optimal growth, increased dietary fiber may exacerbate issues related to malabsorption, and a high-sodium diet is generally not recommended due to the risk of dehydration and electrolyte imbalances in individuals with cystic fibrosis.

5. How should a healthcare professional handle a child with a new diagnosis of type 2 diabetes?

A. Focus on increasing physical activity and dietary management
B. Initiate insulin therapy immediately
C. Limit all carbohydrate intake
D. Recommend frequent fasting

Correct answer: A

Rationale: In managing type 2 diabetes in a child, focusing on increasing physical activity and dietary management is crucial, especially in the initial treatment phase. This approach helps improve insulin sensitivity and overall glycemic control. Initiating insulin therapy immediately is not the first-line treatment for type 2 diabetes in children. Limiting all carbohydrate intake is not advisable as carbohydrates are essential for providing energy and nutrients. Recommending frequent fasting can be harmful and is not a recommended strategy for managing type 2 diabetes in children.
