About Mary

Hi! I’m Mary Purdy – Integrative and Eco-Dietitian, Speaker, Writer and Adjunct Faculty Lecturer

An excerpt from my kindergarten teacher’s evaluation: “Food means a lot to Mary. If she doesn’t like her lunch it ruins her entire day.” It was true then, and it’s true now.

I love food! I love the field of nutrition. And I’m passionate about our environment and sustainability.  My goal is to help people, practitioners and organizations discover how a sustainable, resilient, healthy and equitable food system can support both people and planet.

Food and lifestyle choices can give you more energy, help you feel better, prevent illness, and maybe even reverse certain disease states.  They can also play a significant role in mitigating the climate crisis and protecting the environment which is in need of extra support.

I bring my skillset, knowledge and experience to individuals, communities, organizations, educational institutions and food companies in order to connect the dots between human and planetary health, one meal at a time. With an expertise in both integrative and functional medicine and sustainable food systems, as well as creative communications and  systems-thinking, I am your ally in working towards creating a more regenerative and healthy planet.

While I’m not currently in clinical practice, I have close to 15 years of experience seeing patients.  I am here to be an educator, adviser and/or consultant for your organization, company or students as it relates to the intersection of sustainably grown food, health, and climate change.  I lecture and offer presentations & webinars build course curriculum, write articles and books, create videos, and host the podcasts “The Nutrition Show” and “The Good Clean Nutrition Podcast” (sponsored by Orgain).  You can also take a look at my former youtube web series. Tune in regularly, join the conversation, boost your knowledge and your wellness while helping to support the health of the planet.

Here’s the skinny on my creds…

I’m a Registered Dietitian Nutritionist (RDN) with a Masters in Clinical Nutrition (MS) from Bastyr University. I have almost 15 years of professional nutrition experience: counseling 1-on-1 with an integrative and functional medicine approach, presenting at numerous national conferences, designing courses, speaking to groups, writing articles, and training other professionals. All this in clinics, at corporations, in colleges & universities, in a nutrition textbook, via online webinars, in magazines, on the radio, and on TV.

I also am an expert in sustainable food systems and their connection to the environment, climate and human health.  In particular I have been focused on championing the role that dietitians and healthcare practitioners can play in advocating for sustainabilitiy and equity in the food and agriculture system.   I also help individuals and organizations to connect and network, build community and create partnerships in order to support human and planetary health.
