1. Which of the following are absorbed into the bloodstream without needing additional digestion?

Correct answer: D

Rationale: Amino acids, monosaccharides, and glycerol are absorbed directly into the bloodstream without requiring further digestion.

2. Which animal-derived food contains the most significant level of carbohydrates?

Correct answer: C

Rationale: Milk contains the most significant level of carbohydrates among animal-derived foods. Milk and milk products supply significant quantities of carbohydrate in the form of lactose. Eggs, beef, and poultry are not significant sources of carbohydrates compared to milk. In cheese making, lactose is removed as a by-product, reducing the carbohydrate content further.

3. Each statement accurately describes the physical effects of food on periodontal health, except one. Which is the exception?

Correct answer: D

Rationale: The correct answer is D. Chewing soft, spongy foods does not stimulate salivary flow; rather, firm, fibrous foods like fruits and vegetables do. Soft foods can stick to teeth, promoting plaque buildup. Choices A, B, and C are accurate: Supragingival plaque biofilm adhesion is influenced by both monosaccharides and disaccharides, while poor nutrition can indeed have adverse effects on the periodontium.

4. Which of the following is a good food source of iodine?

Correct answer: A

Rationale: Seafood is a rich source of iodine, essential for maintaining healthy thyroid function and overall metabolic health. While lettuce, broccoli, and pork may contain some iodine, they do not provide as substantial an amount as seafood. Therefore, they are not considered 'good' sources of iodine in comparison.

5. Which nutrient is critical for wound healing and immune function?

Correct answer: B

Rationale: Vitamin C is essential for collagen formation and immune function.
