1. Why are diets that contain less than 10% of kcalories as fat not recommended?

• A. Intake of carbohydrates would not necessarily be too high.
• B. This would not necessarily require excessive use of fat replacers.
• C. The diet would not provide adequate essential fatty acids.
• D. Intake of essential fatty acids would be too low.

Correct answer: D

Rationale: Diets that contain less than 10% of kcalories as fat are not recommended because they would lead to inadequate intake of essential fatty acids, which are crucial for various bodily functions like hormone production, brain function, and cell membrane structure. Option A is incorrect because reducing fat intake does not necessarily mean increasing carbohydrate intake excessively. Option B is incorrect as it introduces a new concept of using fat replacers, which is not directly related to the issue of essential fatty acid intake. Option C is incorrect as the primary concern with low-fat diets is the insufficiency of essential fatty acids, not the adequacy of them.

2. Plasma lipoproteins contain varying amounts of:

• A. ascorbic acid.
• B. triglycerides.
• C. lecithin.
• D. glucose.

Correct answer: B

Rationale: The correct answer is B: triglycerides. Plasma lipoproteins, such as LDL and HDL, contain triglycerides, cholesterol, and other fats. Ascorbic acid (choice A) is not typically found in plasma lipoproteins; it is a form of vitamin C. Lecithin (choice C) is a phospholipid found in cell membranes but is not a major component of plasma lipoproteins. Glucose (choice D) is a type of sugar and is not a primary component of plasma lipoproteins.

3. In addition to protein, which nutrients contribute to the building and repair of tissue?

• A. Vitamins
• B. Carbohydrates
• C. Fats
• D. Enzymes

Correct answer: A

Rationale: The correct answer is A: Vitamins. Vitamins play a crucial role in tissue building and repair along with protein. Carbohydrates (choice B) are primarily a source of energy and not directly involved in tissue building. Fats (choice C) are important for energy storage and insulation but are not the main contributors to tissue building. Enzymes (choice D) are biological catalysts and do not directly contribute to tissue building and repair.

4. Which of the following are macronutrients?

• A. Minerals.
• B. Proteins.
• C. Vitamins.
• D. Enzymes.

Correct answer: B

Rationale: Proteins are indeed macronutrients, along with carbohydrates and fats. Macronutrients are nutrients that provide energy and are required in large amounts by the body. Minerals and vitamins are considered micronutrients, as they are needed in smaller quantities. Enzymes, on the other hand, are not nutrients but rather biological molecules that act as catalysts in biochemical reactions.

5. Exchange Lists for Meal Planning was devised by the American Dietetic Association in collaboration with which organization?

• A. the American Cancer Society
• B. the American Diabetes Association
• C. the American Heart Association
• D. the Culinary Institute of America

Correct answer: B

Rationale: The correct answer is B: the American Diabetes Association. The American Dietetic Association collaborated with the American Diabetes Association to devise the Exchange Lists for Meal Planning. This collaboration aimed to assist individuals, especially those with diabetes, in planning balanced meals. Choices A, C, and D are incorrect as they were not involved in the development of the Exchange Lists.
