Treat each nutrient separately
FDA describes percent Daily Value as a comparison with the reference amount for a particular nutrient. The percentages are separate comparisons, not pieces of a single pie chart. Adding the column vertically does not produce a useful measure of how nutritious a serving is.
Read one row at a time
For a comparison note, keep the nutrient name, its amount, its unit and its percent Daily Value together. First establish that the servings being compared are equivalent. A percentage without the row label loses the identity of the reference being used.
Do not turn a reference into a prescription
The percentage can help interpret a U.S. label, but it is not an individually calculated requirement. A reader following clinical dietary advice should not replace that advice with the panel’s general reference. This guide explains the column’s structure and does not assign a personal target or food rating.
