Label v. Lab: How do sodium values compare?

A study by Ahuja et al compared the sodium values on product labels with laboratory values of popular sodium-contributing foods in the US.

The comparative analysis of 114 foods (1,390 composites, consisting of one or more samples of the same food) showed that a majority of label and laboratory values were in agreement.

Periodic monitoring can help establish label validity and inform the correction of discrepancies identified in products.
