Dr Therese O'Sullivan and her team are investigating the difference in children's health after three months on a low-fat and full fat dairy diet in the world-first Milky Way Study.
They'll compare gut health, cardiovascular health and obesity of about 50 children from around Perth as part of the study.
They hope the study's findings will provide good quality evidence for future dietary guidelines for children.
