In this cross-sectional, controlled study, patients\u2019 dietary habits were assessed via subjective ratings of beneficial and trigger foods, followed by standardized food frequency surveys (FFS). Scores for disease-specific risk stratification based on dietary habits were proposed. Clinical assessments, dermatologic examinations, and laboratory analyses were performed. A total of 296 patients (acne group (AG) n = 120, control group (ACG) n = 32; rosacea group (RG) n = 105, control group (RCG) n = 39) were included. The significant impact of diet on disease severity was self-reported by 80.8% of the AG and 70.5% of the RG. Leading dietary triggers were found in both groups, while beneficial food items were identified more clearly by the AG. FFS revealed significant dietary differences between the AG, RG, and control groups. Disease-specific scores showed greater precision for acne (odds ratio 14.5 AG, 5.5 RG). The AG had higher insulin-like growth factor (IGF)-1 levels correlating with dairy intake (p = 0.006). Overall, this study underlines the influence of diet on acne and rosacea, providing valuable disease-specific scores for dietary risk stratification. Consuming vegetables, legumes, oily fish, olive oil, and nuts, and limiting meat, cheese, and alcohol appear to be beneficial for both acne and rosacea. Future studies can build on these data to further improve preventive and therapeutic strategies.<\/jats:p>","DOI":"10.3390\/nu15204405","type":"journal-article","created":{"date-parts":[[2023,10,17]],"date-time":"2023-10-17T08:10:19Z","timestamp":1697530219000},"page":"4405","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Dietary Patterns in Acne and Rosacea Patients\u2014A Controlled Study and Comprehensive Analysis"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6865-0526","authenticated-orcid":false,"given":"Anne","family":"Guertler","sequence":"first","affiliation":[{"name":"Department of Dermatology and Allergy, LMU University Hospital, LMU Munich, 80539 Munich, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arina","family":"Volsky","sequence":"additional","affiliation":[{"name":"Department of Dermatology and Allergy, LMU University Hospital, LMU Munich, 80539 Munich, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Quirine","family":"Eijkenboom","sequence":"additional","affiliation":[{"name":"Department of Dermatology and Allergy, LMU University Hospital, LMU Munich, 80539 Munich, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tobias","family":"Fiedler","sequence":"additional","affiliation":[{"name":"Department of Dermatology and Allergy, LMU University Hospital, LMU Munich, 80539 Munich, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lars E.","family":"French","sequence":"additional","affiliation":[{"name":"Department of Dermatology and Allergy, LMU University Hospital, LMU Munich, 80539 Munich, Germany"},{"name":"Dr. Phillip Frost Department of Dermatology and Cutaneous Surgery, Miller School of Medicine, University of Miami, Miami, FL 33136, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Markus","family":"Reinholz","sequence":"additional","affiliation":[{"name":"Department of Dermatology and Allergy, LMU University Hospital, LMU Munich, 80539 Munich, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"812","DOI":"10.1111\/jdv.14820","article-title":"The influence of exposome on acne","volume":"32","author":"Dreno","year":"2018","journal-title":"J.
