1. Which food is a high source of prebiotics?

• A. Chicken
• B. Garlic
• C. White rice
• D. Cheese

Correct answer: B

Rationale: Garlic is the correct answer. It is high in prebiotics, which are non-digestible fibers that promote the growth of beneficial gut bacteria. Chicken, white rice, and cheese are not significant sources of prebiotics. Chicken is a good source of protein, white rice is a carbohydrate, and cheese is a dairy product, none of which are high in prebiotics.

2. Sucrose is a:

• A. monosaccharide
• B. disaccharide
• C. polysaccharide
• D. starch

Correct answer: B

Rationale: Sucrose is a disaccharide composed of one glucose and one fructose molecule.

3. Each of the following foods has cariostatic properties, with one exception. Which food is the exception?

• A. Eggs
• B. Instant oatmeal
• C. Cheese
• D. Seafood

Correct answer: B

Rationale: Cariostatic foods are those that contribute to the prevention of tooth decay. Eggs, cheese, and seafood are all cariostatic foods, as they can aid in protecting against tooth decay. On the contrary, instant oatmeal does not possess these cariostatic properties. Due to its processed nature, it is more fermentable and cariogenic, which means it can encourage cavity formation. Although it is not directly harmful to the teeth, it does not provide the same defensive benefits against tooth decay as the other choices do. Therefore, 'Instant oatmeal' is the exception among these foods and is the correct answer.

4. How do foods or supplements containing significant amounts of plant sterols help lower LDL cholesterol levels?

• A. reducing cholesterol synthesis
• B. suppressing inflammation
• C. reducing blood clotting
• D. interfering with cholesterol and bile absorption

Correct answer: D

Rationale: Plant sterols interfere with cholesterol and bile absorption in the intestines. This interference helps lower LDL cholesterol levels by reducing the amount of cholesterol that enters the bloodstream. Choices A, B, and C are incorrect because plant sterols primarily work by interfering with cholesterol and bile absorption, not by reducing cholesterol synthesis, suppressing inflammation, or reducing blood clotting.

5. What is the main function of dietary fiber in managing cholesterol levels?

• A. To reduce absorption of dietary fats
• B. To increase cholesterol synthesis
• C. To enhance protein digestion
• D. To decrease cholesterol absorption

Correct answer: D

Rationale: Dietary fiber helps lower cholesterol levels by binding to bile acids and reducing cholesterol absorption.
