1. To prevent symptoms of fatigue, dehydration, and energy loss, what is the daily recommended minimum intake of carbohydrates?

• A. 130 g.
• B. 230 g.
• C. 330 g.
• D. 430 g.

Correct answer: A

Rationale: The correct answer is A: 130 g. The recommended minimum intake of carbohydrates to prevent fatigue, dehydration, and energy loss is 130 grams per day. Consuming an adequate amount of carbohydrates provides the body with energy and helps prevent symptoms associated with insufficient carbohydrate intake. Choices B, C, and D are incorrect as they suggest higher amounts of carbohydrate intake, which may not necessarily align with the recommended daily minimum intake for preventing symptoms of fatigue, dehydration, and energy loss.

2. Which of the following types of fiber is not a carbohydrate?

• A. gums
• B. lignin
• C. pectin
• D. cellulose

Correct answer: B

Rationale: Lignin is the correct answer because it is a type of fiber that is not a carbohydrate and provides structure to plant cell walls. Gums (choice A), pectin (choice C), and cellulose (choice D) are all types of dietary fiber that are carbohydrates. Gums are a type of soluble fiber, pectin is found in fruits and is a soluble fiber, and cellulose is a type of insoluble fiber found in plant cell walls.

3. Which nutrient group provides the primary source of energy for the body?

• A. Carbohydrates.
• B. Fats.
• C. Proteins.
• D. Vitamins.

Correct answer: A

Rationale: Carbohydrates are the body's primary source of energy. When carbohydrates are consumed, they are broken down into glucose, which is used by the body's cells for energy production. Fats and proteins are also essential nutrients, but carbohydrates are the preferred energy source for the body due to their quick conversion into fuel. Vitamins are not a direct source of energy but play crucial roles in various bodily functions.

4. Which of the following saturated fats does not contain cholesterol?

• A. Butter
• B. Coconut oil
• C. Eggs
• D. Fish

Correct answer: B

Rationale: The correct answer is B, Coconut oil. Coconut oil is a saturated fat derived from plants and does not contain cholesterol, unlike the other options. Butter (choice A) is an animal-derived saturated fat that contains cholesterol. Eggs (choice C) and fish (choice D) also contain cholesterol, making them incorrect choices. Therefore, coconut oil is the only option that is a saturated fat and does not contain cholesterol.

5. Protein is constantly being exchanged between which two components?

• A. tissue and plasma.
• B. the liver and the small intestine.
• C. blood and lymph.
• D. the heart and lungs.

Correct answer: A

Rationale: The correct answer is 'tissue and plasma.' Protein turnover involves the continuous exchange of proteins between body tissues and the bloodstream (plasma) as part of normal metabolic processes. This process ensures a balance in protein levels throughout the body. Choices B, C, and D are incorrect as they do not represent the primary sites for protein turnover in the body.
