1. Why is it important to understand standard serving sizes of foods?
- A. it is easy to eat too much of some nutrients when choosing healthful foods.
- B. serving sizes have generally decreased over the past few decades.
- C. most people have difficulty estimating the amount of food they eat.
- D. food portions need to be weighed to check serving sizes accurately.
Correct answer: C
Rationale: The correct answer is C. Understanding serving sizes is crucial because most people have difficulty estimating the amount of food they eat. It helps individuals accurately track their intake, which is essential for maintaining a healthy diet and avoiding overeating. Choice A is incorrect because the question focuses on portion sizes rather than specific nutrients. Choice B is incorrect as it presents an unsupported claim about serving sizes decreasing. Choice D is incorrect as weighing food portions is not always necessary to check serving sizes; understanding standard serving sizes allows for a more practical approach to portion control.
2. Which phase of metabolism makes growth and repair possible?
- A. digestion
- B. catabolism
- C. anabolism
- D. ketosis
Correct answer: C
Rationale: Anabolism is the phase of metabolism responsible for building up and repairing tissues in the body. It involves processes that require energy to synthesize complex molecules from simpler ones. Digestion (choice A) is the process of breaking down food into simpler substances for absorption. Catabolism (choice B) involves the breakdown of complex molecules into simpler ones with the release of energy. Ketosis (choice D) is a metabolic state where the body uses fat as the primary source of energy, which is not directly related to growth and repair.
3. What are the actions involved in the process of digestion?
- A. thermal and chemical.
- B. chemical and segmental.
- C. muscular and chemical.
- D. mechanical and thermal.
Correct answer: C
Rationale: The correct answer is C: 'muscular and chemical.' In the process of digestion, muscular movements help in mixing and propelling food along the digestive tract, while chemical breakdowns involving enzymes and acids break down food into smaller molecules for absorption. Choices A, B, and D are incorrect as thermal, segmental, and mechanical actions are not the primary actions involved in the digestion process.
4. Carbohydrates are composed of a combination of carbon, hydrogen, and which other element?
- A. oxygen.
- B. nitrogen.
- C. water.
- D. glucose.
Correct answer: A
Rationale: Carbohydrates are composed of carbon, hydrogen, and oxygen. These three elements combine to form the basic structure of carbohydrates. Oxygen is an essential element in carbohydrates, contributing to their chemical composition. Choice B (nitrogen) is incorrect as nitrogen is not a typical component of carbohydrates. Choice C (water) is incorrect as water is not an element but a compound composed of hydrogen and oxygen. Choice D (glucose) is incorrect as glucose is a specific type of sugar, not an element found in the composition of carbohydrates.
5. 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.
