why does the RDA drop from 1,250mcg to 700mcg for pregnant women under 18 to when you're over 19?
ReplyDeleteAdequate calcium intake is necessary for the attainment of peak bone mass in the late teens (i.e the highest level of bone strength which occurs at completion of growth) and therefore strong healthy bones, which will sustain the effects of aging on the skeleton. (http://www.bonehealthforlife.org.au/content/view/18/480/) Women who are pregnant at age 18 or under are still very young and their bodies are still growing and developing so they need double the amount to account for themselves and their baby.
ReplyDeleteI also checked a couple of other RDA tables of various websites and they recommended 1000mg for the 19-30 year old range while pregnant rather than 700mg.
Do you know what kind of nuts and seeds contain phosphorus?
