This one-day seminar will explore how diet is important not only for physical health, but also for optimal mental development and functioning. The programme has been designed specifically for psychotherapists and other practitioners wishing to investigate the possibility that their patients or clients may have psychological symptoms arising from a dietary deficiency. Conditions such as anxiety, depression, bipolar disorder and schizophrenia are implicated and we will learn how nutrition can play an important role in their prevention and management. We will also consider dilemmas about how a psychotherapist may incorporate this possibility into a talking-cure.
