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 the recommended dietary intake of protein for adults?

• A. 0.5 g/kg.
• B. 0.8 g/kg.
• C. 1.0 g/kg.
• D. 1.5 g/kg.

Correct answer: B

Rationale: The recommended dietary intake of protein for adults is 0.8 grams per kilogram of body weight. This amount is considered adequate for most healthy adults. Choices A, C, and D are incorrect as they do not align with the generally recommended protein intake for adults.

3. What is the basis of MyPlate food guidance?

• A. Percentage of calories from each macronutrient.
• B. Exchange Lists for Meal Planning.
• C. Appropriate amounts of food from each food group.
• D. Amounts of macronutrients and micronutrients.

Correct answer: C

Rationale: The correct answer is C: 'Appropriate amounts of food from each food group.' MyPlate food guidance focuses on portion sizes from different food groups to promote a balanced diet. Choices A, B, and D are incorrect because MyPlate emphasizes the consumption of a variety of foods from different food groups rather than focusing solely on macronutrient percentages, exchange lists, or specific nutrient amounts.

4. What are dextrins?

• A. Polysaccharides.
• B. End products of starch digestion.
• C. Formed in the liver.
• D. Rapidly excreted.

Correct answer: A

Rationale: Dextrins are a type of polysaccharides formed during the breakdown of starch. Choice A is correct because dextrins are indeed polysaccharides, not the end products of starch digestion (Choice B). They are not formed in the liver (Choice C) nor rapidly excreted (Choice D).

5. In a low-carbohydrate diet, most of the calories are supplied by:

• A. proteins.
• B. fats.
• C. carbohydrates.
• D. vitamins.

Correct answer: B

Rationale: In a low-carbohydrate diet, fats become the primary source of calories as carbohydrate intake is restricted. Proteins can contribute to caloric intake but are not the primary source in a low-carbohydrate diet. Carbohydrates are intentionally limited in this diet, so they do not supply most of the calories. Vitamins are essential nutrients but do not provide calories.
