Mediterranean Dietary Intervention for HS

This study involves a 16-week Mediterranean-style eating program for people with hidradenitis suppurativa (HS). The program is called the Med-South Lifestyle Program (MSLP) and is designed to support practical, realistic dietary changes. Most study activities are completed remotely. Participants will have two in-person visits, at the beginning and end of the study, usually scheduled after a regular dermatology appointment to avoid an extra clinic trip. Participants will receive one-on-one nutrition counseling by video call from dietetic students supervised by a registered dietitian. Counseling sessions occur throughout the 16 weeks and include nutrition education, goal setting, and practical strategies for following a Mediterranean-style diet. Participants will also complete a cooking education session and receive written program materials. Participants will receive some food support, including Mediterranean pantry staples such as olive oil, herbs, and spices, as well as prepared meals delivered during the study. Food allergies, intolerances, and dietary restrictions will be reviewed before food is provided. Participants will complete brief questionnaires during the study and additional study activities at the beginning and end. These visits may include health measurements and collection of blood, urine, saliva, stool, and skin swab samples. At the end of the study, participants will also have an opportunity to provide feedback about their experience with the program.
