About Anna

Where Science Meets Individualized Nutrition Care

As a Registered Dietitian Nutritionist with a Master's Degree in Nutrition and Dietetics, Anna Petersen founded FoodFirst LLC on the belief that food, used thoughtfully and strategically, is one of the most powerful tools available for supporting health.

Anna works with clients on digestive, metabolic, cardiac, and thyroid health, areas that are often closely connected and benefit from more time and individualized attention than a standard medical visit allows. Her approach combines a thorough intake, current nutrition science, and a plan built around your specific history, labs, and goals.

Food First

Whole food as the foundation of every plan; supplements support that foundation, not replace it.

Evidence Based

Recommendations grounded in current nutrition science, and updated as the research evolves.

Individualized Care

No two clients receive the same plan. Every recommendation is tailored to your history and goals.

What Individualized Plans Actually Look Like on a Plate

Balanced macronutrients, built around real food
A whole food plate with eggs, avocado, greens, and tomatoes
Protein and fiber, paired thoughtfully
A bowl of yogurt topped with berries, walnuts, and chia seeds
Simple, satisfying, and sustainable
