What does a Dietitian do?

You may have heard of a dietitian, but do you know what they can do?

Dietitians are qualified and regulated health professionals who assess, diagnose and treat dietary and nutritional problems, across different specialisms, both at an individual and public-health level.

By using the most recent public health and scientific research on food, health and disease; dieticians translate this into practical guidance to allow people to make appropriate lifestyle and food choices.

Dietitians aren’t just limited to the NHS, they can work with people of all ages in a variety of settings.
