1. What is the maximum recommended daily intake of cholesterol?

• A. 100 mg.
• B. 200 mg.
• C. 300 mg.
• D. 400 mg.

Correct answer: C

Rationale: The correct answer is C: 300 mg. The recommended maximum daily intake of cholesterol is 300 mg to reduce the risk of heart disease. Option A (100 mg) is too low, which may not provide enough cholesterol for normal bodily functions. Option B (200 mg) is also below the recommended limit. Option D (400 mg) exceeds the recommended daily intake, increasing the risk of heart disease.

2. The Dietary Guidelines are published and revised by the U.S. Department of Agriculture in association with the:

• A. Department of Health and Human Services.
• B. National Institutes of Health.
• C. National Academy of Sciences.
• D. Food and Nutrition Board.

Correct answer: A

Rationale: The correct answer is A. The U.S. Department of Agriculture collaborates with the Department of Health and Human Services to publish and revise the Dietary Guidelines for Americans. This collaboration ensures that the guidelines encompass both agricultural and health aspects. Choices B, C, and D are incorrect as they are not directly involved in the publication and revision of the Dietary Guidelines. The National Institutes of Health focuses on medical research, the National Academy of Sciences provides independent scientific advice, and the Food and Nutrition Board is a part of the National Academies of Sciences, Engineering, and Medicine.

3. 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.

4. Which of the following is an example of a protein?

• A. Saline.
• B. Hemoglobin.
• C. Cellulose.
• D. Prostaglandins.

Correct answer: B

Rationale: Hemoglobin is a protein that carries oxygen in the blood, making it the correct answer. Choice A, Saline, is a salt solution and not a protein. Choice C, Cellulose, is a complex carbohydrate found in the cell walls of plants, not a protein. Choice D, Prostaglandins, are lipid compounds with hormone-like effects, not proteins.

5. Which of the following foods are major sources of starch?

• A. Fruits
• B. Meats
• C. Legumes
• D. Milk

Correct answer: C

Rationale: The correct answer is C: Legumes. Legumes, such as beans and lentils, are major sources of starch, providing complex carbohydrates. Fruits (choice A) mainly provide sugars rather than starch. Meats (choice B) and milk (choice D) are not significant sources of starch as they mainly provide protein and fats, respectively. Therefore, choices A, B, and D are incorrect.
