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. What is the maximum recommended daily intake of cholesterol?

• A. 100 mg.
• B. 200 mg.
• C. 300 mg.
• D. 400 mg.

Correct answer: C

Rationale: The correct answer is C: 300 mg. The recommended maximum daily intake of cholesterol is 300 mg to reduce the risk of heart disease. Option A (100 mg) is too low, which may not provide enough cholesterol for normal bodily functions. Option B (200 mg) is also below the recommended limit. Option D (400 mg) exceeds the recommended daily intake, increasing the risk of heart disease.

3. Why are bacteria found in the colon important?

• A. synthesize important vitamins.
• B. complete the process of absorption.
• C. synthesize some minerals.
• D. finish the process of digestion.

Correct answer: A

Rationale: Bacteria found in the colon are important because they synthesize important vitamins, such as vitamin K. This aids in the body's overall health and functioning. Choice B is incorrect because absorption primarily occurs in the small intestine, not the colon. Choice C is incorrect as the synthesis of minerals is not a primary function of colon bacteria. Choice D is incorrect as the digestion process mainly occurs in the stomach and small intestine.

4. What does the Tolerable Upper Intake Level (UL) represent?

• A. a replacement for Recommended Dietary Allowances (RDAs).
• B. a safe level of intake for people of all ages.
• C. a potentially toxic level of intake of a nutrient.
• D. the highest amount of a nutrient that can be safely consumed.

Correct answer: D

Rationale: The Tolerable Upper Intake Level (UL) represents the highest amount of a nutrient that can be safely consumed without causing adverse health effects. It is not a replacement for Recommended Dietary Allowances (RDAs) (choice A) which are nutrient intake recommendations. While the UL is established to prevent toxicity, it is not a completely safe level for people of all ages (choice B). It is also not a potentially toxic level of intake of a nutrient (choice C), but rather the level that is unlikely to cause adverse health effects.

5. 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.
