1. Where is Vitamin B12 found?

• A. Whole grains.
• B. Nuts.
• C. Meats.
• D. Legumes.

Correct answer: C

Rationale: Vitamin B12 is primarily found in animal-derived foods like meats. Choices A, B, and D are incorrect as whole grains, nuts, and legumes do not naturally contain significant amounts of Vitamin B12. Therefore, the correct answer is 'C: Meats.'

2. What is the primary function of carbohydrates as a food source?

• A. Regulate metabolic processes.
• B. Build body tissue.
• C. Supply energy.
• D. Provide bulk.

Correct answer: C

Rationale: The primary function of carbohydrates as a food source is to supply energy. Carbohydrates are the body's main source of energy, providing fuel for various physiological functions. Choice A is incorrect because carbohydrates do not primarily regulate metabolic processes; that role is mainly attributed to enzymes and hormones. Choice B is incorrect because proteins are primarily responsible for building body tissue. Choice D is incorrect because fiber, not all carbohydrates, provides bulk in the diet.

3. What are the major sources of energy for the body?

• A. Proteins and fats.
• B. Carbohydrates and fats.
• C. Proteins and carbohydrates.
• D. Vitamins and minerals.

Correct answer: B

Rationale: The correct answer is B: Carbohydrates and fats. Carbohydrates are the body's primary and most efficient source of energy, providing fuel for daily activities. Fats are also a significant energy source, especially during times of prolonged or intense exercise. Proteins are primarily used for building and repairing tissues, not as a major energy source. Vitamins and minerals are essential for various bodily functions but do not serve as direct sources of energy.

4. 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.

5. A food choice equivalent to one serving from the Protein group of MyPlate is:

• A. 1 tbsp peanut butter.
• B. 3 oz fish.
• C. 2 oz cheese.
• D. 1/2 cup cooked dry beans or peas.

Correct answer: A

Rationale: One tablespoon of peanut butter is equivalent to one serving from the Protein group in MyPlate. It provides a good amount of protein and healthy fats. Choices B, C, and D are incorrect as they represent larger serving sizes than a single serving from the Protein group in MyPlate. 3 oz of fish, 2 oz of cheese, and 1/2 cup of cooked dry beans or peas would exceed the recommended serving size for the Protein group.
