Why are vitamins and minerals only expressed as a percentage of a Daily Value?
It is easier for consumers to interpret the vitamin and mineral quantities within a food as a percentage of a Daily Value, rather than needing to understand various units like RE or g. Small numbers may be viewed as insignificant and large numbers as significant. For example, 110 mg of sodium (a large number) is only 5% of the Daily Value while 2 mg of iron (a small number) is 15% of the Daily Value.
