London Clinic of Nutrition recognise that the greatest health threats now arise from how we live, work and eat. Seven basic principles characterise functional medicine: Acknowledging the biological individuality of each human being, based on the concepts of genetic and environmental uniqueness. Addressing the web-like interconnections of internal physiologic factors. Promoting organ reserve as a means of enhancing the health span, not just the lifespan, of each patient. Incorporating a patient centred rather than a disease centred approach to treatment. Seeking a dynamic balance among the internal and external factors in the patient body, mind and spirit. Identifying health as a positive vitality not merely the absence of disease and emphasising those factors encourage a vigorous physiology. Staying abreast of emerging research – a science based approach.
