Association Between Adult Acne and Dietary Behaviors: Findings From the NutriNet-Santé Prospective Cohort Study
Cross-sectional study as part of NutriNet-Santé study (n=24,452) found consumption of milk (aOR, 1.12; 95% CI, 1.00-1.25), sugary beverages (1.18; 1.01-1.38), and fatty and sugary products (1.54; 1.09-2.16), appeared to be associated with current acne in adults.

SPS commentary:
According to an editorial, these findings are largely in line with prior observational studies suggesting an association between milk consumption and high glycaemic-load diet with acne. It notes that in this study, the effect sizes were generally small and an association between diet and acne may not be clinically meaningful for many patients, thus the findings should be interpreted with caution with respect to clinical practice, and dietary interventions may be better thought of as adjunctive strategies rather than primary treatment options. In addition, as some dietary interventions, such as avoiding dairy products, may have other relevant effects (e.g. reduced calcium and vitamin D intake), they should be cautiously implemented for patients looking for dietary modifications that may improve their acne. Further trials are needed to evaluate whether dietary interventions can improve or prevent acne and how the effect size of such interventions compares with other standard treatment modalities.
