In this presentation, Mary Purdy, MS, RDN, CD, will present research on the potential negative health effects of numerous environmental toxicants. She will provide useful strategies for minimizing exposure to external toxicants in our food supply and improving the channels of detoxification through realistic dietary and lifestyle modifications and therapeutic interventions. Additionally, she will examine the role of genetic variants and the potential use of supplementation to improve pathways. She will also discuss how our current food and agricultural system contribute to the presence of toxicants in our food supply and the ways that RDN's can advocate for systemic, institutional and individual changes to create a healthier and more equitable approach to growing, producing and accessing food that promotes wellness and supports the environment.
