Question:

Which of the following statements are true in the context of a balanced diet for adults:
(A). Women require as much energy giving foods as men of the corresponding age
(B). Men require as much iron rich foods as women
(C). Protein needs for sedentary as well as for strenuously hard working male would be the same.
(D). As the activity level increases the requirement for energy and B Vitamins increases
(E). Calcium requirement for adult male and female is 1000mg/d.
Choose the correct answer from the options given below:

Show Hint

B-vitamins are energy-releasing vitamins.
Whenever energy requirements go up (due to hard work or exercise), the requirements for Thiamine, Riboflavin, and Niacin always increase proportionally.
  • (A), (B) and (D) only.
  • (B), (C) and (D) only.
  • (C), (D) and (E) only.
  • (A), (C) and (E) only.

The Correct Option is C

Solution and Explanation

Step 1: Understanding the Concept:
A balanced diet provides all necessary nutrients in the correct quantities based on age, gender, and physical activity level as specified by dietary guidelines (such as ICMR-NIN).

Step 2: Detailed Explanation:

Let us analyze each statement:
1. Statement (A) is False: Men generally have higher basal metabolic rates (BMR) and greater lean muscle mass than women of corresponding age, requiring more daily energy.
2. Statement (B) is False: Men require less dietary iron than women. Women of reproductive age lose iron regularly during menstruation and therefore have a significantly higher iron requirement.
3. Statement (C) is True: The RDA for protein is calculated based on body weight (e.g., \(1\text{ g/kg body weight/day}\)) and does not vary with physical activity level, unlike energy requirements.
4. Statement (D) is True: Physical activity increases calorie consumption. B-vitamins (Thiamine, Riboflavin, Niacin) function as coenzymes in carbohydrate and energy metabolism, so their requirements scale directly with energy expenditure.
5. Statement (E) is True: According to ICMR-NIN (2020) guidelines, the recommended dietary intake for calcium is \(1000\text{ mg/day}\) for both adult men and women.
Therefore, statements (C), (D), and (E) are correct.

Step 3: Final Answer

The correct option is (C).
