This is a question I get a lot. I’m a dietitian AND a nutritionist, which I think is important.
Nutritionists know what food to eat to get all the nutrients we need to be healthy. It’s vitally important in my work that I know these things: knowing the basic facts behind what I’m recommending is the first step to helping someone find a healthy diet that works for them.
A dietitian is always a nutritionist, but a nutritionist is not always a dietitian. Dietitians have gone to uni to get a whole lot of extra knowledge: particularly important is nutrition counselling (helping people make the changes, not just giving instructions), and medical nutrition therapy (specialised diets for different medical conditions).
There’s also the Accredited Practicing Dietitian (APD) qualification. All dietitians in Australia who’ve studied an approved course can apply to the Dietitians Association of Australia, which gets them an APD qualification. Being a member of the DAA means you’re subject to professional codes of ethics, including continuous professional development. I’m pretty proud of my APD accreditation, as it says that I’m committed to ethical practice.
I hope this clears things up! xx
