Hi all! --About the Vit C per infant juice used by breastfed infants or in general, it is my understanding that Vit C source foods eaten with the grain source food of iron, helps the body to absorb the iron. Correction of iron defiency anemia is one of the purposes of WIC. Michigan Department of Public Health puts out a pamphlet entitled, Ironing Out Your Diet, and I have used this info for all ages. After all of this discussion I'm personnaly motivated to hike over to MSU and do some reading of the sources Kathryn Dettwyer has recommended. .Cynthia J. Church RN,BSN,IBCLC
