1. The number of kilocalories provided by a food that contains 22g of fat is:

• A. 88
• B. 132
• C. 154
• D. 198

Correct answer: D

Rationale: The correct answer is D. Fat provides 9 kcal per gram, so 22 grams of fat will provide 198 kcal (22g * 9 kcal/g = 198 kcal). Choice A (88) is incorrect because it miscalculates the kcalories. Choice B (132) is incorrect as it does not consider the correct kcaloric value of fat. Choice C (154) is incorrect as it also does not calculate the kcalories accurately based on the fat content.

2. Exchange Lists for Meal Planning was devised by the American Dietetic Association in collaboration with which organization?

• A. the American Cancer Society
• B. the American Diabetes Association
• C. the American Heart Association
• D. the Culinary Institute of America

Correct answer: B

Rationale: The correct answer is B: the American Diabetes Association. The American Dietetic Association collaborated with the American Diabetes Association to devise the Exchange Lists for Meal Planning. This collaboration aimed to assist individuals, especially those with diabetes, in planning balanced meals. Choices A, C, and D are incorrect as they were not involved in the development of the Exchange Lists.

3. Which hormone prevents excessive gastric activity?

• A. Gastrin
• B. Enterogastrone
• C. Secretin
• D. Cholecystokinin

Correct answer: B

Rationale: The correct answer is Enterogastrone. Enterogastrone is a hormone that inhibits excessive gastric activity by slowing down stomach contractions and emptying. Gastrin (choice A) stimulates gastric acid secretion, secretin (choice C) regulates pH levels in the duodenum, and cholecystokinin (choice D) stimulates the release of digestive enzymes and bile.

4. How many kilocalories are provided by 15 grams of protein?

• A. 15
• B. 45
• C. 60
• D. 135

Correct answer: C

Rationale: Protein provides 4 kcal per gram. Therefore, 15 grams of protein will provide 15 grams x 4 kcal/gram = 60 kcal. Choices A, B, and D are incorrect because they do not consider the caloric value of protein correctly.

5. The sum of all chemical processes inside living cells of the body that sustain life and health is known as:

• A. physiology
• B. digestion
• C. metabolism
• D. nutrition

Correct answer: C

Rationale: Metabolism is the correct answer as it refers to the sum of all chemical processes that occur within living cells to maintain life and health. Physiology (Choice A) is the study of how living organisms function but does not specifically refer to cellular chemical processes. Digestion (Choice B) is the process of breaking down food in the body, not the overall cellular processes. Nutrition (Choice D) is the process of obtaining and consuming food necessary for health and growth, but it does not encompass all cellular processes related to sustaining life and health.
