1. Which of the following monosaccharides is considered one of the most important in human nutrition along with glucose and fructose?

• A. Lactose.
• B. Galactose.
• C. Maltose.
• D. Sucrose.

Correct answer: B

Rationale: The most important monosaccharides in human nutrition are glucose, fructose, and galactose. Galactose is crucial as it is one of the main components of lactose, a disaccharide sugar found in milk. Therefore, choices A, C, and D are incorrect as lactose, maltose, and sucrose are disaccharides composed of two monosaccharide units.

2. 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.

3. Which of the following is a source of complete protein?

• A. Cereal grains.
• B. Beans.
• C. Nuts.
• D. Eggs.

Correct answer: D

Rationale: Eggs are considered a source of complete protein because they contain all the essential amino acids required by the body. The other options, cereal grains, beans, and nuts, do not provide all the essential amino acids in the necessary proportions to be classified as complete proteins.

4. Which gastric enzyme present in infants coagulates milk?

• A. Casein.
• B. Pepsinogen.
• C. Trypsin.
• D. Rennin.

Correct answer: D

Rationale: The correct answer is D, rennin. Rennin is the enzyme in infants responsible for coagulating milk, which aids in the digestion process. Choice A, casein, is a milk protein and not an enzyme. Choices B and C, pepsinogen and trypsin, are digestive enzymes but are not specifically involved in coagulating milk in infants.

5. Major nutrients supplied by foods in the Vegetables group of MyPlate include:

• A. potassium and vitamin A.
• B. iron and vitamin C.
• C. calcium and vitamin B12.
• D. sodium and vitamin E.

Correct answer: A

Rationale: The correct answer is A: potassium and vitamin A. Vegetables are an excellent source of potassium and vitamin A, both essential for maintaining overall health. Iron and vitamin C (choice B) are commonly found in foods from the Protein and Fruits groups, respectively. Calcium and vitamin B12 (choice C) are more abundant in dairy products and animal-based foods. Sodium and vitamin E (choice D) are not the major nutrients typically supplied by vegetables.
