1. It has been generally accepted that the percentage of total daily calories supplied by fats should be no more than:

A. 10% to 15%.
B. 10% to 35%.
C. 20% to 35%.
D. 40% to 55%.

Correct answer: C

Rationale: The recommended fat intake is between 20% to 35% of total daily calories. This range is considered optimal for maintaining a healthy diet. Choice A (10% to 15%) is too low and might not provide enough essential fats for the body. Choice B (10% to 35%) includes an upper limit that exceeds the generally accepted range. Choice D (40% to 55%) suggests a fat intake that is higher than what is recommended, which could lead to health issues if consumed regularly.

2. The process of breaking down body protein into amino acids for energy is known as:

A. Deamination.
B. Transamination.
C. Transcription.
D. Catabolism.

Correct answer: D

Rationale: The correct answer is D: Catabolism. Catabolism involves the breakdown of body proteins into amino acids to be used as energy when there is an inadequate dietary intake. Choices A and B, deamination and transamination, involve the removal and transfer of amino groups, respectively, but not the breakdown of body proteins. Choice C, transcription, is a process in genetics where DNA is used to create mRNA, not related to breaking down body proteins.

3. Where are sugar alcohols most likely to be found?

A. Fermented foods.
B. Low-calorie foods.
C. Fruits and vegetables.
D. Fiber supplements.

Correct answer: B

Rationale: Sugar alcohols are commonly found in low-calorie foods as sweetening agents without the calorie content of regular sugars. Choices A, C, and D are incorrect because sugar alcohols are not typically found in fermented foods, fruits, vegetables, or fiber supplements. Therefore, the correct answer is B.

4. What is one useful outcome of keeping a record of everything you eat and drink for a day?

A. Precise estimates of portion sizes.
B. Determination of appropriate energy intake.
C. Estimation of supplement needs.
D. Increased awareness of personal food patterns.

Correct answer: D

Rationale: The correct answer is D: Increased awareness of personal food patterns. Keeping a food record is beneficial as it helps individuals become more mindful of their eating habits and food choices. This awareness can lead to identifying patterns, triggers, and areas for improvement in one's diet. Choices A, B, and C are incorrect because the primary benefit of keeping a food record is not about precise estimates of portion sizes, determining energy intake, or estimating supplement needs, but rather about developing a deeper understanding of personal food patterns.

5. With respect to its effect on colon microflora, fiber is considered a:

A. prebiotic.
B. probiotic.
C. functional food.
D. protective agent.

Correct answer: A

Rationale: The correct answer is A: prebiotic. Fiber acts as a prebiotic by providing a food source for beneficial bacteria in the colon, promoting their growth and activity. This helps maintain a healthy balance of microflora in the gut. Choice B, probiotic, is incorrect as fiber itself does not contain live beneficial bacteria but rather supports their growth. Choice C, functional food, is too broad and doesn't specifically address fiber's role in promoting beneficial bacteria. Choice D, protective agent, is vague and does not directly relate to fiber's specific function in colon microflora.
