Gut health & immunity

The Plant Power Doctor

 A doctor for over 17 years, Gemma Newman has worked in many specialities as a doctor including elderly care, endocrinology, paediatrics, obstetrics and gynaecology, psychiatry, general surgery, urology, vascular surgery, rehabilitation medicine and General Practice.

Dr Newman's specialist interests are in holistic health and plant-based nutrition as well as lifestyle medicine. In her practice she has come to understand that body, mind and soul are not separate, and that it is only in addressing the root causes of stress and disconnection that we can truly heal, from the inside out.

Nutritional Therapist

Eve’s career first started in the dizzy heights of fashion PR and it was anything BUT “healthy”. Meaning long hours, grabbing whatever she could on the go and/or skipping meals plus being sucked into weird diets and all that silly stuff along with the surmounting pressures of maintaining a high-profile job.

Her gut health started to show the first signs of being unhappy and this lead to recurrent infections and eventually a bit of a miserable viscous cycle. Eventually she found the answers through nutritional therapy and functional medicine which prompted her to help others in the same way.

Eve believed that having a positive and healthy approach to food & nutrition is not about restriction or rules. It is having an inclusive, diverse and embracive repertoire with our food.

She believes in working towards a balanced and functional approach that supports the body, most notably the gut, on a deeper and more intrinsic level so that we can achieve optimum well-being.
