1. Which of the following are considered micronutrients?
- A. Fats.
- B. Proteins.
- C. Vitamins.
- D. Carbohydrates.
Correct answer: C
Rationale: Micronutrients are essential nutrients needed by the body in small quantities to support various bodily functions. Vitamins fall under this category as they play crucial roles in metabolism, immune function, and overall health. While fats, proteins, and carbohydrates are essential macronutrients required in larger amounts for energy and growth, they are not classified as micronutrients. Therefore, the correct answer is C.
2. What is the most prevalent dietary disaccharide?
- A. Lactose
- B. Fructose
- C. Sucrose
- D. Galactose
Correct answer: C
Rationale: Sucrose is the correct answer as it is the most common disaccharide found in the diet, commonly known as table sugar. Lactose is a disaccharide found in dairy products, not as prevalent in the overall diet as sucrose. Fructose is a monosaccharide commonly found in fruits and honey, not a disaccharide. Galactose is a monosaccharide commonly found in dairy products and is not the most prevalent dietary disaccharide.
3. A food choice equivalent to one serving from the Grains group of MyPlate is:
- A. one slice of bread
- B. 2 cups of rice
- C. 3 cups of spaghetti
- D. 4 oz of ready-to-eat cereal
Correct answer: A
Rationale: One slice of bread is a standard serving from the Grains group in MyPlate. This choice aligns with the recommended portion size for grains. Choices B, C, and D are excessive portions that do not represent a single serving according to MyPlate guidelines. 2 cups of rice, 3 cups of spaghetti, and 4 oz of ready-to-eat cereal exceed the standard serving size for grains and would provide more than one serving from this food group.
4. Which mineral helps strengthen tooth enamel and prevent dental caries?
- A. Calcium
- B. Phosphorus
- C. Fluoride
- D. Zinc
Correct answer: C
Rationale: The correct answer is C, Fluoride. Fluoride is a mineral known for its ability to strengthen tooth enamel and prevent dental caries. While calcium (Choice A) is essential for strong bones and teeth, it is not specifically known for preventing dental caries. Phosphorus (Choice B) is crucial for bone health but is not directly associated with preventing dental caries. Zinc (Choice D) is not typically recognized for strengthening tooth enamel or preventing dental caries.
5. Which of the following is an example of a plasma protein?
- A. Collagen.
- B. Myosin.
- C. Albumin.
- D. Phospholipid.
Correct answer: C
Rationale: The correct answer is C, albumin. Albumin is a plasma protein that plays a crucial role in maintaining fluid balance in the blood. Collagen (choice A) is a structural protein found in connective tissues, not a plasma protein. Myosin (choice B) is a protein involved in muscle contraction, not found in the blood plasma. Phospholipid (choice D) is a type of lipid molecule, not a protein present in plasma.
