Question 1:
Which of the following is a key nutrient that provides energy to the body?
A) Proteins
B) Carbohydrates
C) Vitamins
D) Minerals
Correct Option: B) Carbohydrates
Rationale: Carbohydrates are the body's primary source of energy. They are broken
down into glucose, which is utilized for various bodily functions. Proteins and fats also
provide energy but to a lesser extent.
Question 2:
What is the recommended daily intake of fiber for adult women?
A) 14 grams
B) 21 grams
C) 25 grams
D) 30 grams
Correct Option: C) 25 grams
Rationale: The recommended daily intake of fiber for adult women is 25 grams. Fiber is
essential for digestive health and can help manage weight and cholesterol levels.
Question 3:
Which vitamin is primarily responsible for blood clotting?
A) Vitamin A
B) Vitamin B12
C) Vitamin K
D) Vitamin C
Correct Option: C) Vitamin K
Rationale: Vitamin K plays a crucial role in the synthesis of proteins required for blood
,clotting. Without sufficient vitamin K, proper blood coagulation can be impaired,
leading to excessive bleeding.
Question 4:
In what form is the majority of dietary fat stored in the body?
A) Triglycerides
B) Phospholipids
C) Cholesterol
D) Fatty acids
Correct Option: A) Triglycerides
Rationale: The majority of dietary fat is stored in the body as triglycerides. These
molecules consist of glycerol and three fatty acids and are stored in adipose tissue for
energy use when needed.
Question 5:
Which mineral is essential for the formation of hemoglobin?
A) Magnesium
B) Iron
C) Calcium
D) Potassium
Correct Option: B) Iron
Rationale: Iron is a critical component of hemoglobin, the protein in red blood cells
that carries oxygen. A deficiency in iron can lead to anemia, which is characterized by
fatigue and weakness.
Question 6:
Which nutrient is essential for maintaining healthy skin and vision?
A) Vitamin D
B) Vitamin A
C) Vitamin E
D) Vitamin C
Correct Option: B) Vitamin A
Rationale: Vitamin A is crucial for maintaining healthy skin and vision. It plays a vital
role in cell growth and differentiation and is necessary for the function of
photoreceptors in the retina.
Question 7:
,What is the primary function of dietary protein?
A) Energy production
B) Immune function
C) Tissue repair and growth
D) Hormone regulation
Correct Option: C) Tissue repair and growth
Rationale: The primary function of dietary protein is to provide the building blocks
(amino acids) necessary for tissue repair and growth. While proteins can provide energy,
their main role is not energy production.
Question 8:
What is the best source of omega-3 fatty acids?
A) Butter
B) Flaxseeds
C) Chicken
D) Corn oil
Correct Option: B) Flaxseeds
Rationale: Flaxseeds are an excellent source of omega-3 fatty acids, particularly alpha-
linolenic acid (ALA). Omega-3 fatty acids are known for their anti-inflammatory
properties and support for heart health.
Question 9:
Which dietary component can help lower cholesterol levels?
A) Saturated fats
B) Trans fats
C) Soluble fiber
D) Sugar
Correct Option: C) Soluble fiber
Rationale: Soluble fiber can help lower cholesterol levels by binding to cholesterol in
the digestive system and promoting its excretion. Foods rich in soluble fiber include
oats, beans, and fruits.
Question 10:
Which vitamin enhances iron absorption from plant sources?
A) Vitamin C
B) Vitamin D
, C) Folate
D) Vitamin B12
Correct Option: A) Vitamin C
Rationale: Vitamin C enhances iron absorption from plant sources (non-heme iron) by
converting it into a more absorbable form. Consuming vitamin C-rich foods alongside
iron-rich plant foods improves overall iron uptake.
Question 11:
What is the recommended dietary allowance (RDA) for calcium in adults?
A) 800 mg
B) 1,000 mg
C) 1,200 mg
D) 1,500 mg
Correct Option: B) 1,000 mg
Rationale: The RDA for calcium in adults is 1,000 mg per day to support bone health
and prevent osteoporosis. Women over 50 and men over 70 should aim for 1,200 mg
daily.
Question 12:
What is a primary consequence of vitamin D deficiency?
A) Scurvy
B) Rickets
C) Pellagra
D) Beriberi
Correct Option: B) Rickets
Rationale: Vitamin D deficiency can lead to rickets, a condition characterized by weak
or soft bones in children due to impaired calcium absorption. In adults, it can lead to
osteomalacia.
Question 13:
Which of the following is a complete protein source?
A) Beans
B) Nuts
C) Quinoa
D) Lentils
