Changes in Diet Quality and Total and Cause-Specific Mortality

Abstract

Sotos-Prieto et al. (July 13 issue)1 report that improvement in diet quality during the 12-year study period was consistently associated with a reduced risk of death. Their report may be easily interpreted as suggesting that beneficial effects of specific foods or a type of diet (e.g., the Alternate Mediterranean Diet and Dietary Approaches to Stop Hypertension [DASH] diet, as evaluated in the study) contributed to the reduction in the risk of death.
