1. The nutrients involved in metabolic regulation and control include minerals, vitamins, and:

• A. amino acids.
• B. carbohydrates.
• C. fats.
• D. water.

Correct answer: D

Rationale: The correct answer is D, water. Water plays a crucial role in metabolic regulation along with vitamins and minerals. While amino acids, carbohydrates, and fats are essential nutrients for various bodily functions, they are not primarily involved in metabolic regulation and control.

2. 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.

3. Which option below is an example of a meal or snack that contains complementary proteins?

• A. an egg and cheese omelet
• B. a peanut butter sandwich
• C. trail mix with nuts and raisins
• D. mixed bean salad with green beans, kidney beans, and white beans

Correct answer: B

Rationale: The correct answer is B, a peanut butter sandwich. A peanut butter sandwich combines grains from the bread and proteins from the nuts in the peanut butter, providing complementary proteins. This combination offers all essential amino acids. Choices A, C, and D do not contain complementary proteins as they lack the combination of different protein sources necessary to provide a complete amino acid profile.

4. 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.

5. Signs of malnutrition can appear when:

• A. nutrient reserves are depleted.
• B. nutrient intake exceeds daily needs.
• C. energy intake is restricted.
• D. caloric expenditure increases.

Correct answer: A

Rationale: The correct answer is A: 'nutrient reserves are depleted.' Signs of malnutrition manifest when the body's reserves of essential nutrients are exhausted and can no longer sustain health. Choice B is incorrect because excessive nutrient intake exceeding daily needs does not lead to malnutrition but may cause other health issues. Choice C is incorrect as restricting energy intake may lead to weight loss but not necessarily malnutrition. Choice D is also incorrect as increasing caloric expenditure does not directly cause malnutrition.
