1. A food choice equivalent to one serving from the Protein group of MyPlate is:

• A. 1 tbsp peanut butter.
• B. 3 oz fish.
• C. 2 oz cheese.
• D. 1/2 cup cooked dry beans or peas.

Correct answer: A

Rationale: One tablespoon of peanut butter is equivalent to one serving from the Protein group in MyPlate. It provides a good amount of protein and healthy fats. Choices B, C, and D are incorrect as they represent larger serving sizes than a single serving from the Protein group in MyPlate. 3 oz of fish, 2 oz of cheese, and 1/2 cup of cooked dry beans or peas would exceed the recommended serving size for the Protein group.

2. Cholecystokinin (CCK) is produced in the:

• A. duodenum.
• B. stomach.
• C. pancreas.
• D. liver.

Correct answer: A

Rationale: Cholecystokinin (CCK) is produced in the duodenum, not the stomach, pancreas, or liver. It is released in response to the presence of food in the duodenum, where it plays a crucial role in regulating digestive processes by stimulating the release of bile from the gallbladder and enzymes from the pancreas. Therefore, the correct answer is the duodenum (Choice A). Choices B, C, and D are incorrect because CCK is not produced in the stomach, pancreas, or liver.

3. What is the primary function of protein in the body?

• A. Provide energy.
• B. Regulate metabolic processes.
• C. Control muscle contractions.
• D. Build tissue.

Correct answer: D

Rationale: The primary function of protein in the body is to build and repair tissues. Proteins are crucial for growth, maintenance, and repair of body tissues, including muscles, organs, and skin. While proteins can be a source of energy, their primary role is not to supply energy. Regulating metabolic processes and controlling muscle contractions are functions typically attributed to other nutrients and compounds in the body, such as vitamins and minerals.

4. Plasma lipoproteins contain varying amounts of:

• A. ascorbic acid.
• B. triglycerides.
• C. lecithin.
• D. glucose.

Correct answer: B

Rationale: The correct answer is B: triglycerides. Plasma lipoproteins, such as LDL and HDL, contain triglycerides, cholesterol, and other fats. Ascorbic acid (choice A) is not typically found in plasma lipoproteins; it is a form of vitamin C. Lecithin (choice C) is a phospholipid found in cell membranes but is not a major component of plasma lipoproteins. Glucose (choice D) is a type of sugar and is not a primary component of plasma lipoproteins.

5. 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.
