Dietitians interpret the science of nutrition to improve health and treat diseases/conditions by educating and giving practical, personalised advice to clients, patients, carers and colleagues.

They advise and help to maintain nutritional status when individuals want to trial dietary interventions such as exclusion diets, nutritional supplementation or dietary interventions in areas such as autism for which evidence is still emerging. They use recognised methodologies to critically appraise the evidence base which includes all forms of evidence and research to inform their advice.

They cannot offer advice where there would be personal financial benefit.
