Health New Zealand's changing up hospital cafe menus in the name of a good diet

Its fresh National Food and Drink policy reduces processed foods, and the portion sizes for things like slices and scones.

Food will need lower saturated fats and added sugar - examples include skinless chicken and fish.

Public Health Service Director Doctor Nick Chamberlain says it would be a bad look if hospitals didn't have healthy food guidelines.

Chamberlain says they're trying to provide guidance, which still gives a huge amount of choice.
