1. Why are diets that contain less than 10% of kcalories as fat not recommended?

• A. Intake of carbohydrates would not necessarily be too high.
• B. This would not necessarily require excessive use of fat replacers.
• C. The diet would not provide adequate essential fatty acids.
• D. Intake of essential fatty acids would be too low.

Correct answer: D

Rationale: Diets that contain less than 10% of kcalories as fat are not recommended because they would lead to inadequate intake of essential fatty acids, which are crucial for various bodily functions like hormone production, brain function, and cell membrane structure. Option A is incorrect because reducing fat intake does not necessarily mean increasing carbohydrate intake excessively. Option B is incorrect as it introduces a new concept of using fat replacers, which is not directly related to the issue of essential fatty acid intake. Option C is incorrect as the primary concern with low-fat diets is the insufficiency of essential fatty acids, not the adequacy of them.

2. A vegetarian diet that includes dairy foods and eggs is known as:

• A. lactovegetarian.
• B. vegan.
• C. semi-vegetarian.
• D. ovolactovegetarian.

Correct answer: D

Rationale: The correct term for a vegetarian diet that includes both dairy foods and eggs is 'ovolactovegetarian.' This term specifically indicates the inclusion of eggs ('ovo') and dairy ('lacto') in the diet. Choice A, 'lactovegetarian,' is incorrect because it only includes dairy products without eggs. Choice B, 'vegan,' is incorrect as it excludes all animal products, including dairy and eggs. Choice C, 'semi-vegetarian,' is incorrect as it is a term used for individuals who occasionally eat meat, poultry, or fish but primarily follow a plant-based diet.

3. Which observation provides evidence that a person has good nutritional status?

• A. Small muscle mass.
• B. Normal weight-to-height ratio.
• C. Smooth tongue.
• D. Fragile skin.

Correct answer: B

Rationale: A normal weight-to-height ratio is a reliable indicator of good nutritional status as it suggests that the person is well-nourished and not underweight or overweight. Small muscle mass (choice A) can indicate malnutrition, a smooth tongue (choice C) can be a sign of vitamin deficiencies, and fragile skin (choice D) can be a sign of poor nutrition or other health issues, but they are not as direct indicators of good nutritional status as a normal weight-to-height ratio.

4. In a low-carbohydrate diet, most of the calories are supplied by:

• A. proteins.
• B. fats.
• C. carbohydrates.
• D. vitamins.

Correct answer: B

Rationale: In a low-carbohydrate diet, fats become the primary source of calories as carbohydrate intake is restricted. Proteins can contribute to caloric intake but are not the primary source in a low-carbohydrate diet. Carbohydrates are intentionally limited in this diet, so they do not supply most of the calories. Vitamins are essential nutrients but do not provide calories.

5. 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.
