,1. What is the recommended dietary allowance (RDA) of protein for an adult with a normal body
weight?
- A) 0.6 g/kg
- B) 0.8 g/kg
- C) 1.0 g/kg
- D) 1.2 g/kg
- Answer: B) 0.8 g/kg
- Explanation: The RDA of protein for an adult with a normal body weight is 0.8 g/kg, which is
about 56 g for men and 46 g for women per day.
2. What are the three main types of carbohydrates and what are their functions in the body?
- A) Monosaccharides, disaccharides, and polysaccharides; they provide energy, regulate blood
glucose, and store glucose as glycogen.
- B) Glucose, fructose, and galactose; they provide energy, regulate blood glucose, and store
glucose as glycogen.
- C) Starch, fiber, and glycogen; they provide energy, regulate blood glucose, and store
glucose as glycogen.
- D) Sucrose, lactose, and maltose; they provide energy, regulate blood glucose, and store
glucose as glycogen.
- Answer: A) Monosaccharides, disaccharides, and polysaccharides; they provide energy,
regulate blood glucose, and store glucose as glycogen.
- Explanation: Carbohydrates are classified into three main types: monosaccharides (simple
sugars), disaccharides (double sugars), and polysaccharides (complex carbohydrates). They have
different structures and functions in the body.
3. What are the two essential fatty acids that cannot be synthesized by the body and must be
obtained from the diet?
- A) Linoleic acid and linolenic acid
- B) Oleic acid and palmitic acid
- C) Arachidonic acid and eicosapentaenoic acid
- D) Stearic acid and lauric acid
- Answer: A) Linoleic acid and linolenic acid
- Explanation: Linoleic acid (omega-6 fatty acid) and linolenic acid (omega-3 fatty acid) are the
two essential fatty acids that cannot be synthesized by the body and must be obtained from the
diet. They are involved in various physiological processes such as inflammation, immunity, blood
clotting, and brain development.
, 4. What are the four fat-soluble vitamins and what are their main functions in the body?
- A) Vitamin A, vitamin D, vitamin E, and vitamin K; they are involved in vision, bone health,
antioxidant activity, and blood clotting respectively.
- B) Vitamin B1, vitamin B2, vitamin B3, and vitamin B12; they are involved in energy
metabolism, nerve function, DNA synthesis, and red blood cell production respectively.
- C) Vitamin C, vitamin B6, folic acid, and biotin; they are involved in collagen synthesis, amino
acid metabolism, DNA synthesis, and carbohydrate metabolism respectively.
- D) Vitamin D, vitamin E, vitamin K, and vitamin C; they are involved in bone health,
antioxidant activity, blood clotting, and collagen synthesis respectively.
- Answer: A) Vitamin A, vitamin D, vitamin E, and vitamin K; they are involved in vision, bone
health,

Question #15: the recently revised food label requires the amounts of which vitamins and
minerals to be on the packaging label?
-iron, calcium, potassium, vitamin D
● Which of the following best applies to nutrient density?
- Consume foods that have the most nutrition for their kcalories
● A healthy diet is based on what three basic principles?
- Variety, balance, and moderation
