Emma Marshall

Registered Nutritional Therapist and Functional Medicine Practitioner


Emma is a registered Nutritional Therapist, Certified Oncology Nutrition Consultant and experienced chef who specialises in working with breast cancer patients.

Constantly learning through formal education and research, Emma combines her evidence-based nutrition knowledge with over 25 years of cooking experience both in professional and domestic environments.  This enables her to take the science of nutrition and the healing it can bring and make it accessible for her clients through her recipes and menu plans.

Her focus is on nutrition, working with you to provide a personalised and supportive approach to identify and reduce your risks and optimise your overall outcome.  She regularly uses functional testing and is experienced and has trained with genetics, stool testing, blood and hormone testing.

Emma started her career as a Chef in London and then ran her own catering business and cookery workshops for 20 years before qualifying as a Nutritional Therapist at The College of Naturopathic Medicine in London in 2018. She completed the Applying Functional Medicine in Clinical Practice (AFMCP) training from the Institute of Functional Medicine shortly afterwards. Emma also obtained the NTEC accredited professional training in Nutrition and Cancer in 2018 from the Institute of Optimum Nutrition in London.

Emma is a teaching assistant at the Oncology Nutrition Institute in the USA.  The Oncology Nutrition Institute (ONI) provides evidence-based educational certification and training programmes in the emerging field of modern, integrative, metabolic, and outcomes-based oncology nutrition therapy.

In parallel, Emma completed Dr Nia Fuller Shavel’s 6 month System Approach to Cancer course, which sets a new standard in cancer nutrition education in the UK.  It is an evidence-based training programme that draws on Dr Fuller-Shavel’s extensive medical, scientific and integrative care knowledge, as well as systems biology and continually evolving understand of cancer pathophysiology.

Emma has been a helpline volunteer since 2018 with Yes To Life, the UK’s Integrative Cancer Care Charity.

I am a proud member of three leading Governing Bodies for nutrition and complementary healthcare – the British Association for Applied Nutrition and Nutritional Therapy (BANT), the Association of Naturopathic Practitioners (ANP) and the BSIO (British Society for Integrative Oncology). I hold professional liability insurance with Balens Ltd.
