Over the last few decades, scientists have been uncovering an uncomfortable truth: Our current modern food environment is affecting our mental health. In this lecture, Prof Rucklidge will first briefly describe what is known about our current food environment and mental health and then discuss the recent paradigm shift of using a broad spectrum of micronutrients (vitamins and minerals) to treat psychiatric problems (e.g., ADHD, depression, stress, emotional dysregulation), reviewing when supplementation might be necessary, the hypothesized mechanisms of action and the current clinical evidence. The talk intends to challenge our current treatment regime for mental disorders and suggest one alternative course of action.
