Milk, high fat and sugary diet may cause adult acne: JAMA Dermatology

Laetitia Penso, University of Paris, France, and colleagues assessed the association between dietary behavior and current acne in adults.

For the purpose, the researchers performed a cross-sectional study as part of the NutriNet-Santé study -- an ongoing observational, web-based cohort study that was launched in France in May 2009. A total of 24 452 participants completed an online self-questionnaire to categorize their acne status: never acne, past acne, or current acne, from November 14, 2018, to July 8, 2019. The researchers studied associations between dietary behavior (food intake, nutrient intake, and the dietary pattern derived from a principal component analysis) and current or past acne. 

"The findings demonstrate that the consumption of milk, sugary beverages, and fatty and sugary products appeared to be associated with current acne in adults. Further large-scale studies are warranted to investigate more closely the associations between diet and adult acne," concluded the authors.

The study, "Association Between Adult Acne and Dietary Behaviors: Findings From the NutriNet-Santé Prospective Cohort Study," is published in the journal JAMA Dermatology.
