Adherence to French Dietary Guidelines is Associated with Reduced Risk of Mortality in the E3N French Prospective Cohort

This research article examines the relationship between adherence to the 2017 French dietary guidelines and mortality in a cohort of over 72,000 women from the E3N French prospective study. The findings show that higher adherence (measured via the sPNNS-GS2 score) is associated with a lower risk of all-cause mortality, cardiovascular disease mortality, and mortality from several cancers, including breast and lung cancer. However, for very high levels of adherence, the trend reverses for some cancer-related outcomes. The association held even after adjusting for dietary exposure to chemical contaminants. These results support the public health value of promoting national dietary guidelines to reduce mortality risks.
