The values on food labels will often contain a '% of USRDA' for vitamins and
minerals. So how can they do that if the recommended values vary by sex and
age? The answer is that they are labeled according to regulations created quite
a few years ago that standardize vitamins and minerals across the board, which
means that it is basically easier for them to print labels.
To find out a customized RDA, based on your age and
sex, go to the Diet Plan tab in Do-It!, then click the Nutrient Profile button.
Your RDAs will be shown, as well as information on each nutrient.
