Question

Given is a group of individuals. Based on current recommendations for Niacin (RDA) arrange them in the order of lowest requirements to highest requirements.
(A) Man moderate work
(B) Boys 16-18 years
(C) Girl 13-15 years
(D) Girl 10-12 years
(E) Boy 7-9 years
Choose the correct answer from the options given below:

• A. (C), (E), (B), (A), (D).
• B. (D), (B), (E), (C), (A).
• C. (B), (A), (D), (C), (E).
• D. (E), (D), (C), (A), (B).

Hint:

To arrange these groups quickly, associate the nutrient requirements with the metabolic and physical activity demands of each age group.
Adolescent boys (16-18 years) often have higher energy requirements than moderately active adult men, resulting in a higher niacin requirement.

Answer 1

The Correct Option is D

To solve this question, we need to arrange the given individuals according to their Recommended Dietary Allowances (RDA) for Niacin from the lowest to the highest requirements. The question refers to different age and gender groups, each with specific nutritional requirements set by health authorities.

Let's break down the requirements for each group:

• Man, moderate work (A): Adult males generally have higher Niacin requirements due to body weight and energy expenditures. The RDA for adult males engaging in moderate work is higher compared to younger children and adolescents.
• Boys, 16-18 years (B): Teenage boys require more Niacin as they are in a growth phase, which typically necessitates higher energy intake.
• Girl, 13-15 years (C): Teenage girls also have increased nutrient needs; however, these are generally less than those of teenage boys.
• Girl, 10-12 years (D): The Niacin requirement for pre-teen girls is less than for older teenagers but might be close to or higher than young boys.
• Boy, 7-9 years (E): Young boys have the lowest Niacin needs compared to all the other groups.

Based on these considerations, we can order the groups by increasing Niacin requirement:

1. (E) Boy, 7-9 years
2. (D) Girl, 10-12 years
3. (C) Girl, 13-15 years
4. (A) Man, moderate work
5. (B) Boys, 16-18 years

The correct sequence according to the options provided is: (E), (D), (C), (A), (B).

Therefore, the answer aligns with the current understanding of RDA for the different age and gender groups, proven by dietary guidelines which state the specific nutrient needs based on age, gender, and activity level. Understanding these RDAs is crucial for preparing dietary plans and ensuring nutritional adequacy among different demographics.
