• Deborah is a great communicator who spoke passionately about the role of diet at our Royal College of General Practitioners Faculty meeting last autumn. The content of her talk was well-researched and clear, including the scientific evidence base as well as practical advice based on years of clinical experience.

Thinking Nutrition delivers expertise in nutrition intervention for mental health and emotional well-being. Deborah Colson, founder, is available for nutrition consultations, corporate projects, lectures and other speaking or writing engagements.

  • I consulted Deborah for my son (then aged 11) who was experiencing learning and behavioural difficulties. Following some tests, we followed an exclusion diet and supplement programme for 6 months. We were also given dietary advice on healthy eating and, as a result, the whole family has changed their eating patterns. Five years on, our son has voluntarily stayed on for higher education – something we could never have imagined back then.
