Updated: May 31, 2023


The realm of nutritional care is a landscape painted with varied professional roles - nutritionists, dietitians, and nutritional therapy practitioners. Each discipline has its unique domain, expertise, and approach towards promoting health and wellness. Here, we

explore these roles to appreciate their distinct contributions.


Nutritionists: Promoting Public Health and Wellness


Nutritionists are advocates for public health and wellness, providing general guidance, education and personal or corporate consultancy services to improve food choices and lifestyle habits. They serve as an invaluable resource for individuals and organisations seeking to enhance well-being through informed dietary decision-making.


However, it's important to note that the title 'nutritionist' is not legally regulated in the UK. This means that a broad spectrum of professionals may use the umbrella term 'nutritionist', ranging from those with extensive qualifications to others with less formal training. Ensuring the nutritionist you engage with has the appropriate credentials is critical. Nutrition professionals who have studied on an approved degree-level (UK NQF level 6 or Scottish NQF level 10) course may register with the UK Voluntary Register of Nutritionists (UKVRN - regulated by the Association for Nutrition) and often use the term ‘Registered Nutritionist’, or as a ‘Registered Public Health Nutritionist’. UKVRN-registered nutritionists without dietetic training cannot offer dietary advice to those with medical conditions since they have not undertaken any clinically supervised nutrition practice training. However, they can recommend food and healthy eating to help prevent or alleviate specific ailments or symptoms.

Nutrition professionals who have studied on an approved degree-level (UK NQF level 6 or Scottish NQF level 10) course in Nutritional Therapy or Nutrition Science may be registered with the British Association for Nutrition and Lifestyle Medicine (BANT) and may use the term 'BANT Registered Nutritionist' when acting in non-clinical nutrition profession capacity. This may include education, writing, clinical supervision, mentoring, and industry and corporate consultancy service provision.


Dietitians: Regulated Medical Nutrition

Dietitians stand at the intersection of nutrition and medical healthcare services, translating nutritional science knowledge and evidence-based practice into sometimes life-saving interventions that align with an individual's health status. Dietitians often work within a hospital setting and can support doctors and patients in complex situations, such as requiring tube feeding or severe malnutrition, which may be life-threatening, in acute and chronic disease management. They may also work in community settings.


The term 'Dietitian' is legally regulated, and anyone using this title in the UK must register with the Health and Care Professionals Council (HCPC) and the British Dietetics Association (BDA). To be eligible, Dietitians must complete an accredited undergraduate or post-graduate degree in Dietetics, which includes supervised training in hospital and community settings.

Nutritional Therapy Practitioners: Pioneers in Personalised Nutrition

Nutritional therapy practitioners (NTPs), as defined by the British Association for Nutrition and Lifestyle Medicine (BANT), adopt a personalised approach to nutrition. They design nutrition plans that respect the individual's unique nutritional and biochemical needs. This process involves a detailed evaluation of the individual's lifestyle factors, family history, and personal health objectives. Leveraging this wealth of information, NTPs identify potential nutritional imbalances, formulate strategies to reduce the physiological and biochemical stressors driving disease processes, and support the body's natural healing mechanisms. This holistic approach positions nutritional therapy practitioners as vital players in preventative healthcare and wellness promotion.

BANT-registered nutritional therapy practitioners must have undertaken degree-level qualifications in applied nutritional medicine or nutritional therapy. Their education includes a minimum requirement for clinical training, which occurs in a private community clinic setting and does not include hospital-based training. To be eligible to practice, BANT members must join the Complementary and Natural Healthcare Council (CNHC), Complementary and Natural Healthcare Council (CNHC), which is the only government and Professional Standards Authority (PSA) backed voluntary regulatory organisation for complementary therapies in the UK.


Since Nutritional Therapy is not a legally protected title, professionals are titled 'BANT-registered Nutritional Therapy Practitioner' when working with clients to differentiate themselves from other nutrition professionals who are not qualified or registered with BANT and CNHC.

Comparing the Trio: Dietitian vs Nutritionist vs Nutritional Therapist



While all three professionals - nutritionists, dietitians, and nutritional therapy practitioners - share a common goal of improving health through nutrition, their methods and focus areas vary considerably.

Nutritionists typically guide individuals, groups and organisations to adopt healthy eating habits and lifestyle changes, primarily serving those already in good health. The information they provide is not typically personalised to unique health circumstances.

Both dietitians and nutritional therapy practitioners bring their specialised training into play while working with individuals seeking nutrition advice for specific health goals or conditions, such as diabetes or heart disease. Their evidence-based nutritional advice finds application in various clinical settings, helping clients navigate their health journey. Dietitians vs nutritionists may formally diagnose nutritional diseases (deficiency states like Iron-deficiency anaemia) and prescribe supplements available on the NHS to correct these. They may also use medical nutrition therapies, such as Ensure when treating people with severe eating disorders. Only dietitians can provide hospital-based care and support clients with chronic kidney disease.

Nutritional therapy practitioners, with their personalised and holistic approach, cater to the unique biochemical needs of an individual. They delve into an individual's lifestyle, personal health goals, and genetic predispositions, offering a tailored plan to address nutritional imbalances and promote overall well-being. NTPs often use a broader range of supplements, including those with optimised bioavailability or side-effect minimisation, formulations of multiple nutrients in single products, and phytochemical or probiotic supplements unavailable on the NHS. They may also employ a broader range of laboratory tests that help the practitioner to understand the client's current physiological state of health, imbalances and personalised requirements.


Summary Reflections: A Triad of Strength in Nutritional Care


In conclusion, the diversity embodied by nutritionists, dietitians, and nutritional therapy practitioners significantly enhances nutritional care. By understanding each professional's distinct roles and unique strengths, individuals can make informed decisions about the type of nutritional care that best aligns with their special needs and health aspirations.

As the field of nutritional science evolves, fostering collaborative relationships among these professionals remains critical. Their collective expertise, passion, and dedication will continue to drive the progress of nutrition care and support our journey towards a healthier and more empowered society.
