Caroline Kluttz is Registered Dietitian Nutritionist, a licensed provider of medical nutrition therapy by the state of North Carolina, and a member of the North and South Carolina Dietetic Association. Caroline received her Master’s degree in Human Nutrition from Winthrop University in Rock Hill, SC. She completed a 36-week comprehensive dietetic clinical practice program at Novant Health Presbyterian Medical Center and outpatient nutrition therapy, education, wellness and counseling at the Novant Health Heart and Vascular Institute, which has given her a solid foundation to face the abundance of nutrition misinformation that many patients are faced with on a daily basis.

Caroline is also a certified personal trainer and helps individuals find synergy between exercise and nutrition to meet their goals. Food and environmental allergies are a personal and professional interest of hers, having suffered for years with them until recently getting the right help. Caroline is thrilled to be a part of the AAIR team and provide patients with evidence-based, credible, up-to-date nutrition advice with a personalized approach to help patients develop a positive, supportive relationship with their health. Her mission is to help others eat with intention and choose foods that will repair, nourish and support every cell in their body so that food can be as it is intended to be – a nourishment rather than a detriment to health and performance.
