Principal Nutrition (MSc, BANT, CNHC)

About me

I don't use work on your symptoms, I use functional medicine to find the root cause of your symptoms to help resolve them and stop them returning.


BANT-REGULATED:  I am a registered member of the British Association for Nutrition and Lifestyle Medicine (BANT), the professional body for Registered Nutrition Practitioners.  As such, you can be assured that I am suitably qualified to at least degree level, compliant with all legal & BANT requirements and participating in ongoing continuing education events to ensure that all knowledge is totally up-to-date.

EVIDENCE-BASED:  As an evidence-based practitioner, I will be utilising any research-proven strategies to help you to regain your optimum health.  If it’s not scientifically proven to be effective and safe, then it is not considered suitable.  Your health, safety and wellbeing are always the top consideration.

FUNCTIONAL MEDICINE:  We have a new generation of chronic diseases, conditions that deteriorate over time and rarely go away.  Current medicine often labels them ‘incurable’ and only offers symptom management.  Functional Medicine is a relatively new branch of medicine which aims to address root causes of disease.  It asks ‘Why?’ these symptoms occurred and what is their root cause.  By addressing the root cause; this not only resolves the symptoms, but prevents them returning.  The most famous Functional Medicine practitioner in the UK is Dr Rangan Chatterjee from BBC1’s ‘Doctor In The House’.

Information about health conditions (*)

Nutritional therapy can help enhance the well-being of individuals diagnosed with serious medical conditions, but should not take the place of medical treatment and advice. If you have been diagnosed with - or suspect you may have - any of these conditions, please speak to your doctor before starting nutritional therapy or making any major changes to your diet or lifestyle.

Further information

I offer a free 15-minute telephone consultation where we can discuss your health concerns and I can reassure you that I can assist you (please note that I am unable to give nutritional advice in this free session as I will not have your health history, medication details, symptom history, etc and it would therefore not be safe for me to do so).
