1. Exchange Lists for Meal Planning group foods that are equivalent in their:

• A. weight.
• B. serving size.
• C. micronutrient content.
• D. macronutrient content.

Correct answer: D

Rationale: The Exchange Lists for Meal Planning categorize foods based on their macronutrient content, such as carbohydrate, protein, and fat. These lists help individuals make food choices while ensuring similar amounts of macronutrients are consumed. Therefore, the correct answer is D. Choices A, B, and C are incorrect because Exchange Lists focus on macronutrient content, not weight, serving size, or micronutrient content.

2. What is the cause of gas formation in the colon?

• A. Consuming refined foods.
• B. Drinking excess water.
• C. Swallowing air while eating.
• D. Bacterial action on organic compounds.

Correct answer: D

Rationale: Gas formation in the colon is primarily due to bacterial fermentation of undigested carbohydrates. Choice A, consuming refined foods, is incorrect as gas formation is not directly linked to refined foods but rather undigested carbohydrates. Choice B, drinking excess water, is incorrect as water consumption does not lead to gas formation in the colon. Choice C, swallowing air while eating, is incorrect as this may cause belching but not gas formation in the colon. The correct answer is D because bacterial action on organic compounds, specifically undigested carbohydrates, leads to gas production in the colon.

3. The major focus of nutritional recommendations in this century has shifted to:

• A. prevention and control of chronic diseases.
• B. improved sanitation and public health.
• C. prevention and control of infectious diseases.
• D. development of healthful foods using food technology.

Correct answer: A

Rationale: The correct answer is A: prevention and control of chronic diseases. In this century, nutritional recommendations have increasingly emphasized the importance of preventing and managing chronic diseases like obesity, diabetes, cardiovascular diseases, and cancer. Lifestyle factors such as diet play a significant role in the development of these conditions. Option B, improved sanitation and public health, although important for overall health, is not the primary focus of nutritional recommendations. Option C, prevention and control of infectious diseases, is also crucial but does not reflect the current major focus of nutritional recommendations. Option D, development of healthful foods using food technology, is a valid area of interest but is not the primary shift in focus observed in nutritional recommendations.

4. Consuming 30 g of which nutrient would provide the highest number of kcalories?

• A. Carbohydrates
• B. Fat
• C. Protein
• D. Micronutrients

Correct answer: B

Rationale: The correct answer is B, 'Fat.' Fat provides 9 kcalories per gram, which is more than carbohydrates and proteins that provide 4 kcalories per gram each. Therefore, consuming 30 g of fat would yield a higher number of kcalories compared to the same amount of carbohydrates or proteins. Micronutrients do not significantly contribute to kcalories, making them an incorrect choice in this scenario.

5. 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.
