1. Which option below is an example of a meal or snack that contains complementary proteins?

• A. an egg and cheese omelet
• B. a peanut butter sandwich
• C. trail mix with nuts and raisins
• D. mixed bean salad with green beans, kidney beans, and white beans

Correct answer: B

Rationale: The correct answer is B, a peanut butter sandwich. A peanut butter sandwich combines grains from the bread and proteins from the nuts in the peanut butter, providing complementary proteins. This combination offers all essential amino acids. Choices A, C, and D do not contain complementary proteins as they lack the combination of different protein sources necessary to provide a complete amino acid profile.

2. Dietary guidelines are most useful for:

• A. limiting portion sizes.
• B. designing a personal food plan.
• C. making smart food choices.
• D. avoiding excessive nutrient intakes.

Correct answer: C

Rationale: Dietary guidelines are designed to assist individuals in making smart food choices by providing recommendations on what to eat to maintain good health. While portion sizes may be a part of these guidelines, they are not the primary focus. Designing a personal food plan involves individual preferences and needs, which may go beyond general guidelines. Avoiding excessive nutrient intakes is important, but dietary guidelines aim to provide balanced recommendations rather than just focusing on avoiding excess.

• A. ileocecal valve.
• B. pyloric valve.
• C. cardiac valve.
• D. hepatic valve.

Correct answer: A

Rationale: The correct answer is A: ileocecal valve. The ileocecal valve is located between the small intestine and the cecum, controlling the passage of chyme. The pyloric valve (choice B) is located between the stomach and the small intestine, regulating the passage of food from the stomach to the small intestine. The cardiac valve (choice C) refers to the valve between the esophagus and the stomach. The hepatic valve (choice D) is not a correct term related to the passage of chyme from the small intestine into the cecum.

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.

Polyps (choice D) are abnormal tissue growths.
