The RDA of calcium for lactating mothers according to ICMR, 2010 per day is :

Question

Accepted Answer

The correct option is 2:

Students, let us discuss a fundamental concept in maternal and child nutrition, which is the Recommended Dietary Allowance (RDA) of calcium during lactation. The correct answer, 1200 mg per day, is based on the authoritative guidelines published by the Indian Council of Medical Research (ICMR) in their 2010 report, 'Nutrient Requirements and Recommended Dietary Allowances for Indians'. The RDA for a non-pregnant, non-lactating adult Indian woman was set at 600 mg/day in the 2010 report. However, during lactation, a mother produces a significant amount of breast milk, and since calcium is essential for the rapid growth and skeletal development of the infant, a substantial quantity of this mineral is secreted daily into the milk. To meet this high demand and simultaneously protect the mother's own bone health, ICMR recommended a substantial additional allowance. Therefore, the total RDA for lactating mothers was nearly doubled to 1200 mg per day, a value that remained consistent for both the initial (0-6 months) and later (6-12 months) phases of lactation as per the 2010 guidelines. This elevated requirement ensures adequate calcium transfer to the baby while preventing excessive maternal bone demineralization.

The incorrect option is 1:

The intake of 1500 mg of calcium per day is not the standard RDA for lactating mothers according to the ICMR 2010 recommendations. While lactation does impose a high calcium demand, the ICMR expert committee concluded that 1200 mg was the appropriate safe level for meeting these needs in the general Indian population. A figure of 1500 mg/day is often associated with the RDA for pregnant or lactating women in some other global guidelines, or sometimes prescribed in specific clinical settings, but it exceeds the official ICMR 2010 value. Following a recommended allowance higher than the RDA is generally unnecessary for healthy individuals and does not provide additional benefit, especially when considering the bioavailability of the nutrient.

The incorrect option is 3:

The value of 800 mg of calcium per day is inadequate for a lactating mother as per ICMR 2010 standards. This amount, while higher than the ICMR 2010 baseline of 600 mg for an adult woman, fails to account for the substantial additional calcium that is lost through breast milk. The ICMR determined that an additional 600 mg of calcium was required over the baseline for lactating women to cover the needs for milk synthesis and bone maintenance. Therefore, 800 mg represents a shortfall of 400 mg compared to the official recommendation of 1200 mg/day, which could potentially lead to long-term negative consequences for the mother's bone density and overall health.

The incorrect option is 4:

The 600 mg per day value is incorrect because this was the RDA designated for a normal, non-pregnant, and non-lactating adult woman in the ICMR 2010 report. A lactating mother's body is under immense physiological stress to produce nutrient-rich breast milk, which requires mobilizing a large amount of calcium. Since the ICMR 2010 guidelines explicitly recommended an additional intake to meet the demands of milk production, supplementing only the base level of 600 mg would lead to a severe calcium deficit. This deficit would force the mother's body to draw calcium directly from her bones, increasing her risk for conditions like osteoporosis later in life. Hence, 600 mg is simply the maintenance requirement for a non-lactating state and is biologically insufficient during this period.
