1. 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.

2. The interrelated network of nerves within the gastrointestinal wall that regulates its muscular action is known as the:

• A. gastric nerve plexus.
• B. biliary nerve plexus.
• C. intramural nerve plexus.
• D. intestinal nerve plexus.

Correct answer: C

Rationale: The correct answer is C - intramural nerve plexus. This network of nerves regulates the muscular movements within the gastrointestinal wall. The gastric nerve plexus (choice A) specifically relates to the stomach, not the entire gastrointestinal tract. The biliary nerve plexus (choice B) is associated with the bile ducts and gallbladder, not the regulation of muscular action. The intestinal nerve plexus (choice D) is a general term that doesn't specifically refer to the network of nerves within the gastrointestinal wall.

3. Infections are common in people who have inadequate protein intake because of an insufficient quantity of:

• A. insulin.
• B. lipoprotein.
• C. antibodies.
• D. albumin.

Correct answer: C

Rationale: Inadequate protein intake can lead to a decrease in antibody production, making individuals more susceptible to infections. Insulin (Choice A) is a hormone involved in regulating blood sugar levels, not related to protein intake. Lipoprotein (Choice B) is a type of lipid-protein complex involved in lipid transport, not directly related to antibody production. Albumin (Choice D) is a protein that helps maintain oncotic pressure and carries various substances in the blood, but it is not primarily responsible for fighting infections like antibodies.

4. Which of the following is an example of a complete protein?

• A. Milk
• B. Soy
• C. Sesame seeds
• D. Sweet potato

Correct answer: A

Rationale: The correct answer is A, Milk. Milk is considered a complete protein as it contains all the essential amino acids required by the body. Soy (choice B) is also a complete protein, containing all essential amino acids. Sesame seeds (choice C) and sweet potato (choice D) are not complete proteins as they lack one or more essential amino acids needed by the body.

5. Which of the following foods is high in indispensable amino acids?

• A. Lentils
• B. Tofu
• C. Peanuts
• D. Eggs

Correct answer: D

Rationale: The correct answer is D, eggs. Eggs are considered a high-quality protein source as they are rich in indispensable amino acids. Lentils, tofu, and peanuts also contain protein but are not as high in indispensable amino acids as eggs, making them less complete protein sources.
