What ratio is used for adding phosphorus to calcium in infants?

The correct ratio for adding phosphorus to calcium in the diet of infants is based on the nutritional guidelines that support optimal bone development and growth during this critical period. In infancy, the recommended calcium to phosphorus ratio is approximately 2:1. This translates to a phosphorus to calcium ratio of about 1:2, which is often expressed inversely as 1:3 when discussing the amounts of calcium added relative to phosphorus.

Since phosphorus is essential for bone health and works synergistically with calcium, the appropriate balance ensures not just adequate levels of both minerals but also promotes proper metabolism and absorption. The nutritional guidelines indicate that for every 1 part of phosphorus, there should be about 3 parts of calcium, hence the rationale behind the 1:3 ratio is to provide sufficient calcium that supports the phosphorus requirements without leading to an imbalance.

Factors such as ensuring adequate calcium levels while preventing excessive phosphorus are crucial, as high phosphorus relative to calcium can lead to negative health outcomes, including impaired bone mineralization.
