Answer 1

Correct Answer: 8 µg Retinol

Rationale:

The Indian Council of Medical Research (ICMR) in 2010 established that the conversion factor for β-carotene to retinol is 1:8. This means that 8 micrograms (µg) of β-carotene are equivalent to 1 µg of retinol in terms of vitamin A activity.
Vitamin A is essential for various bodily functions, including vision, immune function, and skin health. It exists in two primary forms in the diet: preformed vitamin A (retinol) and provitamin A carotenoids (such as β-carotene).
β-carotene is a precursor to vitamin A and must be converted into retinol in the body to be utilized effectively. The efficiency of this conversion can be influenced by several factors including nutritional status, age, and genetics.

Explanation of Other Options:

6 µg Retinol

Rationale: This conversion factor is lower than the ICMR-2010 standard. It implies a higher efficiency of conversion, which is not consistent with the established 1:8 ratio. Therefore, it is incorrect.

10 µg Retinol

Rationale: This conversion factor is higher than the ICMR-2010 standard. It suggests a lower efficiency of conversion, which again is not consistent with the 1:8 ratio. Hence, it is incorrect.

12 µg Retinol

Rationale: This conversion factor is also higher than the ICMR-2010 standard and implies an even lower efficiency of conversion, which is incorrect according to the established guidelines.

Conclusion:

Among the given options, 8 µg Retinol is the correct conversion factor according to ICMR-2010 standards. It accurately represents the conversion efficiency of β-carotene to retinol, which is crucial for proper dietary planning and ensuring adequate vitamin A intake.
