1. Where are sugar alcohols most likely to be found?

• A. Fermented foods.
• B. Low-calorie foods.
• C. Fruits and vegetables.
• D. Fiber supplements.

Correct answer: B

Rationale: Sugar alcohols are commonly found in low-calorie foods as sweetening agents without the calorie content of regular sugars. Choices A, C, and D are incorrect because sugar alcohols are not typically found in fermented foods, fruits, vegetables, or fiber supplements. Therefore, the correct answer is B.

2. What are the rhythmic contractions that propel food through the intestinal tract called?

• A. Segmentation
• B. Peristalsis
• C. Cardiospasm
• D. Pendular movements

Correct answer: B

Rationale: Peristalsis is the correct answer because it refers to the rhythmic contractions that propel food through the intestinal tract by pushing it along the digestive system. Segmentation, on the other hand, refers to the mixing movements in the intestines rather than the forward movement of food. Cardiospasm is a condition characterized by difficulty swallowing due to the inability of the esophagus to relax, and pendular movements are a type of motility found in the small intestine but do not specifically refer to the propulsion of food.

3. Which of the following are considered micronutrients?

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

Correct answer: C

Rationale: Micronutrients are essential nutrients needed by the body in small quantities to support various bodily functions. Vitamins fall under this category as they play crucial roles in metabolism, immune function, and overall health. While fats, proteins, and carbohydrates are essential macronutrients required in larger amounts for energy and growth, they are not classified as micronutrients. Therefore, the correct answer is C.

4. Which of the following enzymes is found in pancreatic secretions?

• A. Rennin
• B. Pepsin
• C. Chymotrypsin
• D. Casein

Correct answer: C

Rationale: Chymotrypsin is an enzyme found in pancreatic secretions that plays a role in protein digestion. Rennin is primarily found in the stomach and is involved in milk digestion. Pepsin is also a stomach enzyme that aids in protein breakdown. Casein is a protein found in milk, not an enzyme involved in pancreatic secretions. Therefore, the correct answer is Chymotrypsin.

5. 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.
