Navigating New Paths in Mental Health

In this episode, Dr. Emily Deans discusses the field of evolutionary psychiatry and its connection to mental health. Dr. Deans is a board certified psychiatrist and writes the blog Evolutionary Psychiatry, based on the observation that our brains are healthiest when we embrace a diet and lifestyle reflecting the conditions under which we humans evolved.  Dr. Deans has presented at the Ancestral Health Symposium in 2012 and 2018 on topics related to this theme.

In this discussion, we dive into what some of the recent clinical studies are telling us about the connection between food and mood disorders conditions such as depression. In particular, she reviews studies showing anti-depressive effects of a Meditarrean diet with meat, and also omega-3 supplementation.  Dr. Deans emphasizes the importance of considering individual dietary needs and preferences when implementing diet interventions in psychiatric practice. She shares success stories of patients who have experienced improvements in mood through dietary changes, including ketogenic and low-carb diets. She also highlights the connection between glucose tolerance and violent behavior, and the importance of smoothing out blood sugar response by incorporating whole foods into the diet. 

Dr. Deans discusses the emerging recognition within the medical profession of food's impact on mental health. She shares her approach to helping patients reduce or come off psychiatric medications, emphasizing the importance of a multifactorial approach that includes diet, exercise, and psychotherapy. Dr. Deans also discusses the potential risks and benefits of dietary changes for individuals with eating disorders.
