This nutrient is considered the body’s primary fuel source.
- A.
Carb
- B.
Protein
- C.
Fat
Correct Answer
A. CarbExplanation
Carbohydrates are considered the body's primary fuel source because they are easily broken down into glucose, which is used by the body as a source of energy. When carbohydrates are consumed, they are converted into glucose and stored in the muscles and liver as glycogen. When the body needs energy, it can quickly break down glycogen into glucose and use it for fuel. Additionally, carbohydrates are the body's preferred source of energy during high-intensity exercise or activities that require quick bursts of energy.Rate this question:

This nutrient transports Vitamins A, D, E K.
- A.
Carb
- B.
Protein
- C.
Fat
Correct Answer
C. FatExplanation
Fat is the correct answer because it is the nutrient that transports vitamins A, D, E, and K. These vitamins are fat-soluble, meaning they can only be absorbed and transported in the presence of fat. Therefore, consuming adequate amounts of healthy fats is essential for the absorption and utilization of these important vitamins in the body.Rate this question:

By fulfilling the major energy needs of the body, this nutrient spares protein.
- A.
Carb
- B.
Protein
- C.
Fat
Correct Answer
A. CarbExplanation
Carbohydrates are the major source of energy for the body. When carbohydrates are consumed, they are broken down into glucose, which is used by the body as fuel. By providing this energy, carbohydrates spare protein from being used as an energy source. This is important because protein is needed for other functions in the body, such as building and repairing tissues. Therefore, carbohydrates play a crucial role in sparing protein and allowing it to be used for its intended purposes.Rate this question:

Provides for growth of desirable bacteria in the GI tract.
- A.
Carb
- B.
Protein
- C.
Fat
Correct Answer
A. CarbExplanation
Carbohydrates provide a source of energy for the body and are broken down into glucose, which is used by cells for various functions. In the context of the gastrointestinal (GI) tract, carbohydrates can be fermented by beneficial bacteria, such as those in the gut microbiota. These bacteria play a crucial role in maintaining gut health and promoting digestion. Therefore, consuming carbohydrates can support the growth of desirable bacteria in the GI tract, contributing to overall gut health.Rate this question:

This nutrient protects vital organs against trauma.
- A.
Carb
- B.
Protein
- C.
Fat
Correct Answer
C. FatExplanation
Fat is the correct answer because it serves as a protective cushion for vital organs, helping to absorb shock and prevent trauma. Fat also provides insulation for the body, maintaining body temperature and protecting against extreme temperatures. Additionally, certain essential fatty acids play a crucial role in brain function and the development of cell membranes. While carbohydrates and proteins are important for energy and muscle building, they do not have the same protective functions as fat.Rate this question:

- A.
Carb
- B.
Protein
- C.
Fat
Correct Answer
A. CarbExplanation
Carbohydrates provide energy and are the main source of fuel for the body. They are broken down into glucose, which is used by the body's cells for energy. In addition to providing energy, carbohydrates also play a role in promoting the growth of beneficial bacteria in the gastrointestinal (GI) tract. These bacteria help with digestion and the absorption of nutrients. Therefore, carbohydrates are important for maintaining a healthy balance of bacteria in the GI tract, which is essential for overall digestive health.Rate this question:

Water balance, nutrient transport, and muscle contractions require this nutrient.
- A.
Carb
- B.
Protein
- C.
Fat
Correct Answer
B. ProteinExplanation
Protein is the correct answer because it is essential for various bodily functions. Water balance is maintained by proteins in the form of transporters and channels that regulate the movement of water in and out of cells. Nutrient transport is facilitated by proteins, which act as carriers to transport essential molecules across cell membranes. Muscle contractions rely on proteins such as actin and myosin, which are responsible for the movement of muscles. Therefore, protein is crucial for these processes.Rate this question:

This nutrient helps you tolerate exposure to the cold.
- A.
Carb
- B.
Protein
- C.
Fat
Correct Answer
C. FatExplanation
Fat is the correct answer because it provides insulation and helps to maintain body temperature in cold environments. When exposed to cold temperatures, the body relies on stored fat for energy, which generates heat and helps to keep the body warm. Additionally, fat acts as a protective layer around vital organs, preventing heat loss and maintaining core body temperature. Therefore, consuming enough fat in the diet is essential for tolerating exposure to the cold.Rate this question:

This nutrient is a source of fiber.
- A.
Carb
- B.
Protein
- C.
Fat
Correct Answer
A. CarbExplanation
Carbohydrates are a source of fiber. Fiber is a type of carbohydrate that cannot be digested by the body. It helps in regulating digestion, preventing constipation, and promoting a healthy gut. Foods rich in carbohydrates such as fruits, vegetables, whole grains, and legumes are also high in fiber. Therefore, the correct answer is carb.Rate this question:

This nutrient keeps skin, hair, nails healthy
- A.
Carb
- B.
Protein
- C.
Fat
Correct Answer
B. ProteinExplanation
Protein is the correct answer because it is a nutrient that plays a crucial role in maintaining the health of skin, hair, and nails. Proteins are the building blocks of these structures and are necessary for their growth, repair, and maintenance. They provide essential amino acids that are needed for the production of collagen, which gives strength and elasticity to the skin, as well as keratin, which is the main component of hair and nails. Including an adequate amount of protein in the diet promotes healthy skin, hair, and nails.Rate this question:

This nutrient provides twice the energy of the other two macronutrients.
- A.
Carb
- B.
Protein
- C.
Fat
Correct Answer
C. FatExplanation
Fat is the macronutrient that provides twice the energy of the other two macronutrients, carbohydrates and proteins. While carbohydrates and proteins provide 4 calories per gram, fats provide 9 calories per gram. This higher energy content is due to the higher amount of carbon and hydrogen atoms in fat molecules, which are released during metabolism to produce more energy. Therefore, consuming fats can provide a more concentrated and efficient source of energy compared to carbohydrates and proteins.Rate this question:

This nutrient curbs hunger the longest.
- A.
Carb
- B.
Protein
- C.
Fat
Correct Answer
C. FatExplanation
Fat is the correct answer because it is known to provide a feeling of satiety and helps to keep us feeling full for longer periods of time. When we consume fat, it slows down the digestion process, which means that the stomach empties at a slower rate, leading to a prolonged feeling of fullness. Additionally, fat takes longer to break down and absorb in the body, which contributes to its ability to curb hunger for a longer duration compared to carbohydrates or proteins.Rate this question:

This nutrient helps repair body tissues.
- A.
Carb
- B.
Protein
- C.
Fat
Correct Answer
B. ProteinExplanation
Protein is the correct answer because it is a nutrient that plays a crucial role in repairing and building body tissues. It is composed of amino acids, which are essential for the growth, maintenance, and repair of cells and tissues in the body. Proteins are involved in the synthesis of enzymes, hormones, and antibodies, and they also contribute to the formation of muscles, skin, hair, and nails. Therefore, consuming enough protein is important for the repair and maintenance of body tissues.Rate this question:
