"It's really cool they're coming here, I'm really excited."
Ms Bruning said there were now a lot more sick kids and adults than there used to be.
She said 95 per cent of these illnesses related to gut health.
"Our health is related to three things - genetic tendencies, environmental triggers like what you eat, and the gut wall. Eighty per cent of our immune cells are in the gut and maintaining a healthy digestive system is essential to health.
"We have all these diseases like diabetes type one, the autism spectrum, allergies, intolerances, Crohn's disease and behavioral disorders, they all have intestinal permeability."
Ms Bruning said how people approached food was what made them healthy or unhealthy.
"We're so used to thinking that convenience foods are fine and that the food in our supermarket is great.
"We need to become a lot more critical about what it is.
"When you have kids getting sick again and again, they might have an ear infection that needs stents, constantly having days off school or regular diarrhoea, for me personally, it's about getting back to what our grandparents ate.
"It's getting back to being simple."
Ms Bruning said parents needed to stop buying food that was bad for their children .
Eating home-grown vegetables was also important because this sort of food could remedy a number of problems that were often treated by a $30 pack of pills, Ms Bruning said.
