My Story

Sarah Amidon is a Registered Dietitian Nutritionist (RDN) specializing in chronic health conditions and sports performance utilizing targeted evidence-based testing, counseling and nutrition strategies. Whether you are an athlete looking to get to the next level or you suffer from food sensitivities, autoimmune disease, infertility, anxiety, depression or a combination of other symptoms, Root & Fruit Nutrition can help you achieve optimal wellness.

Sarah’s background in dietetics and athletics combined with her personal experience in nutrigenomics, thyroid disease, food sensitivities, chronic infections, infertility, fatigue, IBS, nutrient deficiencies, gut imbalance issues and autoimmune conditions shed light on the “why” of unresolved health conditions over the “what” that so many healthcare providers focus on today. Her clients are more than a diagnosis. Sarah knows firsthand the disappointment and physical limitations that come along with searching for answers and enduring a poor quality of life, while specialists may not have the right skillset to unravel the biochemistry necessary to offer the one thing that can keep us going in a complicated health journey: 



Sarah lives in Indianapolis, IN, with her husband and two boys. She loves playing beach volleyball, drinking tea, camping and going on adventures.
