    A unique opportunity for healthcare practitioners: integrate personalised nutrition in your practice 

    As healthcare professionals increasingly face the challenges of lifestyle-related diseases, many have called for greater training in lifestyle interventions. In 2016, a group of prominent doctors wrote to the medical schools council stating that medical students and practising doctors should receive mandatory training in evidence based lifestyle interventions. Later, in 2018, it was reported in the national press that medical students said they learnt “almost nothing” about the way diet and lifestyle affected health. In one survey that looked at nutrition teaching and practice among medical students and doctors, most respondents felt that their nutrition training was inadequate, with more than 70% reporting less than two hours.(1) Only 26% of doctors were confident in their nutrition knowledge and 74% gave nutritional advice less than once a month, citing lack of knowledge, time and confidence as the main barriers.  

    Yet following a recent government review, commissioned in 2018 and published in 2021,(2) it was reported that doctors would be urged to recommend more non-pharmacological treatments, with at least 10% of prescriptions being pointless or possibly harmful.   

    This is where an understanding of integrative functional nutrition can play an important role.


    What is integrative functional nutrition?

    Integrative functional nutrition is an approach that can help healthcare professionals move their practice beyond a ‘one-size-fits-all’ perspective. Based on a whole-body approach, it focuses on addressing the underlying root cause of symptoms, with personalised diet, nutraceutical and lifestyle interventions being key.   

    Increasingly, research is finding that responses to food after eating vary widely, depending upon our individual unique biology.(3) Functional tests may also inform recommendations based on each person’s unique biology; such as genetic predispositions to nutrient deficiencies, gut microbiota profile, food allergies, hormone imbalances, and the impacts of stress, life stage, or environment — including exposure to toxins such as mould.  

    ION’s pioneering Graduate Diploma in Integrative Functional Nutrition, says ION Dean, Heather Rosa, DipION, FHEA, “is to meet the growing needs of doctors and other healthcare professionals who have been looking to bring personalised nutrition into their practices.”  

    The defining principles of integrative medicine 

      •  Patients/clients and practitioners are partners in the healing process.  
      •  Factors including diet, nutrition, lifestyle and environment are explored.  
      •  Integrative medicine may use conventional and alternative methods, where appropriate.  
      •  Where effective, natural and less invasive interventions should be used whenever possible.  
      •  Integrative medicine neither rejects conventional medicine nor accepts alternative therapies uncritically.  
      •  Good medicine is based on good science. It is inquiry-driven and open to new paradigms.  
      •  Broader concepts of health promotion and prevention of illness are paramount.  
      •  Practitioners of integrative medicine should exemplify its principles and be committed to self-exploration and self-development.
