Background
Anna Petersen, MS, RDN, is a registered dietitian and owner of FoodFirst Nutrition, where she provides personalized, evidence-based nutrition care with a root-cause approach.
Anna earned both her bachelor’s and master’s degrees in Nutrition and Dietetics from Illinois State University. Before opening her private practice, she spent 12 years working in a fast-paced clinical setting, providing medical nutrition therapy to patients with a wide range of complex health conditions. This experience gave her a strong clinical foundation and shaped the comprehensive approach she uses with clients today.
Rather than focusing on symptoms alone, Anna looks at the bigger picture, including nutrition, medical history, lab work, digestive health, lifestyle, medications, and other factors that may be influencing how a client feels. She works collaboratively with each person to create practical, individualized strategies that are realistic, sustainable, and grounded in current research.
Anna works with a variety of health concerns, including digestive disorders, metabolic and hormonal concerns, autoimmune conditions, nutrient deficiencies, cardiovascular health, chronic disease, and weight management. She is especially passionate about helping clients better understand their bodies, improve their relationship with food, and feel confident about the steps they can take to support their health.
Anna continues to stay current with evolving nutrition research and regularly collaborates with other healthcare professionals to provide thoughtful, well-rounded care.
Outside of her practice, Anna enjoys spending time with her family, staying active, and finding simple ways to make nutritious food enjoyable and sustainable.
Her goal is simple: to help clients understand what may be contributing to their health concerns and give them a clear, personalized plan for moving forward.
