1. 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.

2. The mineral that helps control enzyme actions in cell mitochondria that produce and store high-energy compounds is:

A. iron.
B. cobalt.
C. hemoglobin.
D. vitamin B12.

Correct answer: A

Rationale: The correct answer is iron. Iron is essential for enzyme function and energy production within the mitochondria. While cobalt is important for certain enzymes, it is not the primary mineral involved in this specific function. Hemoglobin is a protein in red blood cells that carries oxygen, not a mineral involved in enzyme actions. Vitamin B12 is crucial for nerve function and DNA synthesis but is not directly related to controlling enzyme actions in mitochondria.

3. 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.

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. Which type of carbohydrate helps maintain normal blood glucose levels during fasting periods?

A. Glucose
B. Galactose
C. Dextrins
D. Glycogen

Correct answer: D

Rationale: The correct answer is glycogen. Glycogen is a type of carbohydrate stored in the body that is broken down into glucose to help maintain blood glucose levels during fasting periods. Glucose (choice A) is the simplest form of sugar and is a product of carbohydrate digestion, not the stored form like glycogen. Galactose (choice B) is a monosaccharide found in dairy products. Dextrins (choice C) are intermediate products of starch digestion and not directly involved in maintaining blood glucose levels during fasting.
