THE RETREAT

Set in a lush, subtropical environment across from the 22,000-acre St. Sebastian River Preserve, ChoZen Eco-Retreat & Sanctuary is home to​ approximately ​10,000​ ​species​ ​of flora and fauna and ​25 endangered​ animals, including the Florida Panther. ChoZen is located in the heart of one of North America’s most biodiverse lagoon systems–– the nursing ground for​ ​our oceanic friends, including lagoon fish and shellfish. Regular sightings of dolphins, manatees, wild​ ​turkeys,​ turtles​,​ ​bobcats,​ ​hawks, and more are a natural part of daily life. We invite you to experience this unique environment in a 5-day retreat focused on personal strength building.  This adventure includes meals, lectures, cooking classes, hikes, and workouts, as well as accommodations (5 days and 5 nights).

Lectures and cooking classes will focus on Enhanced Immune Function, Finding Deeper Sleep, and Increased Mental Clarity through digestive health.

Workouts, hikes, and nourishment that specifically target digestive health. Meals and cooking classes will include high-quality proteins and fiber, focusing on nourishing the gut biome.

AND IF COLD PLUNGING IS SOMETHING YOU HAVE  CONSIDERED, THIS IS YOUR OPPORTUNITY….

You will have the opportunity to take a cold plunge as part of your daily experience here in this tropical paradise. . And if cold plunging is not your thing, well- there is a sauna and a heated swimming pool!

Our programs and retreats always incorporate well-sourced, high-quality foods, supplements, and products. All meals use ingredients from the best producers available;  we look for 100% organic food, grass-fed meats, wild, regenerative growing practices, and biodynamic and glyphosate-free labeling. 

With Jan providing cooking classes prior to lunch or dinner, you will learn how to prepare delicious meals that are nutrient-dense while understanding labels and food sourcing.  A recipe book and sources are available for each participant.

Nutritional lectures will cover understanding the science behind the studies. John interprets studies that reinforce the importance of nutrients in health and how they affect specific aspects of disease as well as athletic abilities. We will include the most up-to-date studies on health and wellness, and we will have fun!

We source and find the best of the best. 

Both of these programs will include all the meals and recipes, activities, lectures, and cooking classes.

There will be meditation, journaling, and a time to share your challenges and achievements. Consider a diet and lifestyle that will teach you as you boost your well-being and build strength.

We promote the importance of …

• buying food grown close to home

  getting loads of exercise

  eating a variety of plants (a minimum of 40 a week!)

  eliminating stress

  limiting exposure to toxins and chemicals

  prescribing to functional medicine  

 … and finding gratitude in one’s daily life.

Key to Digestive Health

Your digestive system transports food on a journey through your body: digestion involves collaboration among various organs. These organs extract the necessary nutrients from the food and drinks you consume. Supporting a healthy digestive system is essential for your overall well-being.

We focus on Building a Stronger Gut Microbiome

maintaining a healthy gut microbiome,

support the gut lining,

maintain a healthy gut environment,

For those who prefer a preventative approach to cardiology and adhere to a functional medicine philosophy, which positions nutrition and lifestyle as the foundation of good health, functional medicine may not be suitable for everyone. Our teachings promote a patient-centered method for addressing inflammation and chronic diseases. This approach focuses on uncovering the root causes of illness and restoring health by tackling those underlying issues. It is grounded in systems biology, which examines the interconnectedness of physiological factors, individual genes, the environment, nutrition, and lifestyle, all of which are taken into account in an individual's profile. It represents an evolution in understanding our unique wellness.

ABOUT JOHN AND JAN

John Bagnulo and Jan Buhrman. John and Jan have been offering health and wellness retreats since 2009.

John Bagnulo has an MPH from the University of North Carolina and a Doctorate of Human Nutrition and Food Science from the University of Maine. He has worked as a researcher, a university associate professor, and a clinical consultant for the past 24 years. He currently serves as the Director of Nutrition for Nutritional Medicinals and a faculty member for the Center for Mind-Body Medicine, Washington DC. He has a clinical practice in Middlebury, VT. Much of his clinical practice is with athletes and those involved in physically demanding sports.
Jan Buhrman, M.S. Ed., was the founder and owner of the full-service farm-to-table catering company, The Kitchen Porch, on Martha's Vineyard. Jan has become a food advocate and authority on local sourcing and sustainable agriculture with her years of sourcing foods for her catering business from local fishermen and farmers. Jan has taught thousands of classes on technique and the importance of knowing where your food comes from.  She has raised pigs and chickens and gardens, feeding her family while nourishing the land. In addition to cooking, preserving, and techniques, she teaches about the connections between food and health and about composting and soil regeneration.

John brings the nutrition and the science behind our philosophies and Jan ties in the practical “how-to” of incorporating healthy recipes and lifestyle into one's life. John explores the science behind these approaches to healthy living and presents the latest research to the classes in fun approachable ways. Jan puts it all together by teaching how to incorporate it into your daily life.

In our classes, you will learn about the plant-based diet and how the nutrients and fibers are vital to our gut. We explain how to incorporate animal protein into our diet by eating animals that are grown in the wild or on pasture.It is all related; our heart, brain, and gut health are directly related to our diet and lifestyle, and if it is healthy for the soil or the animals, it’s a good bet it’s healthy for us and the planet too…. Food is medicine, lifestyle is medicine, you get to choose everyday!
