1. In the most recent edition of Choose Your Foods: Exchange List for Diabetes, the three groups into which foods are arranged are:

• A. fruits and vegetables, breads, and meats.
• B. fats, starches and sugars, and meat and milk.
• C. fruits and vegetables, meat and milk, and starches.
• D. carbohydrates, meat and meat substitutes, and fats.

Correct answer: D

Rationale: The correct answer is D: carbohydrates, meat and meat substitutes, and fats. The most recent edition of Choose Your Foods: Exchange List for Diabetes categorizes foods into these three groups for easier meal planning. Choice A is incorrect because it does not include carbohydrates and groups bread with fruits and vegetables. Choice B is incorrect because it separates carbohydrates into starches and sugars, which are usually counted together in diabetes meal planning. Choice C is incorrect as it does not specifically categorize foods into carbohydrates, meat, and fats as per the latest edition.

2. Which of the following is an example of a disaccharide?

• A. Glucose.
• B. Fructose.
• C. Galactose.
• D. Maltose.

Correct answer: D

Rationale: The correct answer is D, Maltose. A disaccharide is formed when two monosaccharides are joined together. Glucose, fructose, and galactose are all monosaccharides, not disaccharides. Therefore, they are not examples of disaccharides.

3. What is the primary nutritional function of the large intestine?

• A. Absorption of fats.
• B. Excretion of waste products.
• C. Excretion of bacteria.
• D. Absorption of water.

Correct answer: D

Rationale: The correct answer is D: Absorption of water. The primary nutritional function of the large intestine is to absorb water from the indigestible food residue that enters it from the small intestine. This absorption of water helps to form solid waste, which is then eliminated from the body. Choices A, B, and C are incorrect because the large intestine is not primarily responsible for the absorption of fats, excretion of waste products, or excretion of bacteria. While the large intestine does play a role in waste elimination and contains bacteria beneficial for digestion, its main function in terms of nutrition is the absorption of water.

4. The type of protein-energy malnutrition (PEM) that develops when the diet lacks protein is called:

• A. kwashiorkor.
• B. marasmus.
• C. anemia.
• D. beriberi.

Correct answer: A

Rationale: The correct answer is A: kwashiorkor. Kwashiorkor is a form of protein-energy malnutrition that arises due to a protein-deficient diet. This condition leads to symptoms such as edema, skin lesions, and fatty liver. Choice B, marasmus, is a form of PEM caused by overall malnutrition (protein and calorie deficiency), resulting in severe wasting and muscle loss. Choice C, anemia, is a condition characterized by a deficiency of red blood cells or hemoglobin, not specifically related to protein deficiency. Choice D, beriberi, is a disease caused by thiamine (Vitamin B1) deficiency, not a form of PEM related to protein deficiency.

5. Where does the absorption of most nutrients occur?

• A. Large intestine.
• B. Small intestine.
• C. Stomach.
• D. Mouth.

Correct answer: B

Rationale: The absorption of most nutrients occurs in the small intestine. This is where digested food is broken down further and absorbed into the bloodstream through the intestinal walls. The large intestine primarily absorbs water and electrolytes, while the stomach mainly aids in digestion by breaking down food with gastric juices. The mouth is responsible for the initial mechanical breakdown of food through chewing and the enzymatic action of saliva, but absorption does not occur there.
