What is an Accredited Practising Dietitian?

Accredited Practising Dietitians (APDs) have the qualifications and skills to provide expert nutrition and dietary advice. APDs are university-qualified professionals that undertake ongoing training and education programs to ensure that they are your most up-to-date and credible source of nutrition information, in line with Dietetics Association Australia (DAA) Professional Standards.

APDs are trained to assess nutritional needs. They also assist people to manage health conditions and diseases using food as Medical Nutrition Therapy. APDs help treat a wide range of conditions including diabetes, heart disease, cancers, gastrointestinal diseases, food allergies, food intolerance’s, disordered eating as well as overweight and obesity.

APDs can help with everyday healthy eating by translating scientific health and nutrition information into practical advice. APDs:

  • Assess individual nutritional needs

  • Develop personalised eating plans

  • Develop medical nutrition therapy plans

  • Deliver group nutrition education sessions

  • Sort out nutrition fact from fiction

  • Undertake nutrition and food research

  • Train health care professionals

  • Develop nutrition communications, programs and policies.

APD is the only national credential recognised by the Australian Government, Medicare, the Department of Veterans Affairs and most private health funds as the quality standard for nutrition and dietetics services in Australia. It is a recognised trademark protected by law. Medicare and most private health funds will provide rebates for visits to private APDs.

Medicare initiatives provide rebates on chronic health conditions under a care plan coordinated by a general practitioner. Medicare rebates are now also payable for group services provided by eligible diabetes educators, exercise physiologist and APDs for people with type 2 diabetes, on referral from a GP. Contact Medicare for further information about rebates.
