Nutritional Therapy is part of Complementary Medicine and is the study and application of nutrition science to support the promotion and maintenance of good health and optimal performance throughout all life stages.

It is part of preventative medicine that supports disease management and control. The educational training increasingly encourages application of the functional medicine model, which enables investigation of different body functions and how they relate to each other to gain a more complete health picture.

Nutritional Therapy generally includes personal one-to-one consultations and a comprehensive health history taking, dietry analysis of a 3 or 7 day diet diary. If it is considered appropriate, cellular biochemical laboratory testing is used to enhance strategies for optimal wellness, I tend to use Genova Diagnostics. Individual food and nutritional plans are based on that person's unique dietary and nutritional needs. Facilitating practical and positive food and lifestyle choices are at the heart of the recommended treatment protocols. This can also include supplements, based on individual testing and latest evidence-based scientific research.

Patients are asked to fill in a diet diary over a typical period 3 to seven days. They are asked to provide some general information about their diet, for example the sort of bread and milk used, what oil is used for cooking or eaten on salads, amounts of jams, sugar and honey consumed.

Ideally they then fill in with as much detail what is eaten and drunk, in what quantity and at what time. Patients are also encouraged to provide information about symptoms such as headaches, IBS, frame of mind, mood etc. This is known as a symptom diary and can be done in conjunction with the diet diary. On completion, the diary is returned to Mary for analysis and review, which usually takes a week. Sometimes the diary is analysed using a computer programme, Food Base. and then appropriate dietary recommendations are made. The emphasis is to provide guidelines tending towards the healthiest diet possible, whilst addressing the concerns of the patient.
