Creighton is one of 28 member institutions of the Association of Jesuit Colleges and Universities. have raised important concerns about the amount of calcium actually delivered by fortified fortified (fôrt adj containing additives more potent than the principal ingredient. beverages. They examined four brands of calcium-fortified soymilk and rice milk and eight brands of calcium-fortified orange juice. Beverages were tested and assigned a score based on the amount of calcium in the beverage that did not dissolve (and that probably would not be drunk) and on the likelihood of the calcium in the beverage being absorbed. A score of 100 indicates a source of calcium that would be well absorbed and that would deliver the amount of calcium on the product's nutrition label. Scores for orange juice ranged from 70 to 99, with most products above 95. Soymilk and rice milk scores ranged from 57.5 to 90. These results suggest that many calcium-fortified beverages do not deliver as much calcium as the label suggests they do. What can consumers do? * Shake calcium-fortified beverages very well to maximize the amount of calcium in your glass. * Use other well-absorbed sources of calcium like kale kale, borecole (bôr`kōl), and collards, common names for nonheading, hardy types of cabbage (var. and collard greens Noun 1. collard greens - kale that has smooth leaves collards cole, kail, kale - coarse curly-leafed cabbage in addition to calcium-fortified beverages. * Contact producers of calcium-fortified beverages and let them know that it is important that their products deliver usable calcium in the amount indicated on the label.
