My coauthors and I appreciate the interest of Drs Engelman and Mattes in our recent publication on dietary sodium intake and risk of congestive heart failure.1 We agree with them on the limitations of dietary data from the NHANES I Epidemiologic Follow-up Study (NHEFS). However, we do not agree with them on their comments about the impacts of these biases on the study conclusion.
