1. The type of protein-energy malnutrition (PEM) that develops when the diet lacks protein is called:
- A. kwashiorkor.
- B. marasmus.
- C. anemia.
- D. beriberi.
Correct answer: A
Rationale: The correct answer is A: kwashiorkor. Kwashiorkor is a form of protein-energy malnutrition that arises due to a protein-deficient diet. This condition leads to symptoms such as edema, skin lesions, and fatty liver. Choice B, marasmus, is a form of PEM caused by overall malnutrition (protein and calorie deficiency), resulting in severe wasting and muscle loss. Choice C, anemia, is a condition characterized by a deficiency of red blood cells or hemoglobin, not specifically related to protein deficiency. Choice D, beriberi, is a disease caused by thiamine (Vitamin B1) deficiency, not a form of PEM related to protein deficiency.
2. 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.
3. The Acceptable Macronutrient Distribution Range for fat recommends that the percentage of total kcalories from fat should fall between:
- A. 10% and 20%.
- B. 20% and 25%.
- C. 20% and 35%.
- D. 30% and 45%.
Correct answer: C
Rationale: The Acceptable Macronutrient Distribution Range (AMDR) for fat suggests that 20% to 35% of total kcalories should come from fat. This range is recommended to maintain good health. Choices A, B, and D are incorrect because they do not fall within the specified range. A lower percentage (10-20%) may not provide enough essential fatty acids, while a higher percentage (30-45%) may increase the risk of health issues associated with excessive fat consumption.
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. Which nutrient group provides the primary source of energy for the body?
- A. Carbohydrates.
- B. Fats.
- C. Proteins.
- D. Vitamins.
Correct answer: A
Rationale: Carbohydrates are the body's primary source of energy. When carbohydrates are consumed, they are broken down into glucose, which is used by the body's cells for energy production. Fats and proteins are also essential nutrients, but carbohydrates are the preferred energy source for the body due to their quick conversion into fuel. Vitamins are not a direct source of energy but play crucial roles in various bodily functions.
