Dr Sarah Brewer is a registered medical doctor, a registered nutritionist, a registered nutritional therapist and the author of over 60 popular health books.

She qualified from Selwyn College, Cambridge University with degrees in Natural Sciences (B.Sc. Hons.) and went on to study at the , University of Cambridge School of Clinical Medicine to qualify in Medicine (M.B.) and Surgery (B.Chir).

While working as a GP and hospital doctor, she recognised that many illnesses are linked to diet and lifestyle choices.

She therefore spent six years studying for a Master’s degree in Nutritional Medicine from the University of Surrey (M.Sc. Nutr. Med.) to learn more about maintaining health and preventing illness through diet rather than treatment with drugs.
