how much milk for kids
After crunching the numbers, the researchers settled on the threshold amount for where milkâs vitamin D benefit was offset by the drop in iron â two cups. Kids who drank two cups of milk daily had healthy levels of Vitamin D and iron, according to the results of the study, published in the journal Pediatrics. âBeyond that, any more milk isnât giving much more benefit in terms of vitamin D but children are still paying a price because their iron stores are going down,â says Maguire. There are some caveats, particularly for children with darker skin, who donât make as much vitamin D from the sun.
