Julie is a police prosecutor and a mother of nearly 4 children. When she saw what food did to her three year old son, she became an enthusiastic supporter of failsafe and a co-founder of the new Brisbane food intolerance support group.

Joseph  gets up from his afternoon tea and goes and whispers to his father Steve. He wants to know if it's okay to eat the marshmallows in his bowl. He's four and he probably can't pronounce food intolerance but he knows how had it makes him feel if he eats things he shouldn't. His mother Julie says if they hadn't found out what was wrong with Joseph when they did he would probably be in jail for murder now.

She says Joe was "broken" from the time he was born and it wasn't until he was diagnosed with food intolerance at three and a half that a solution seemed possible for the little boy. As well as being a mother of three and pregnant with number four, Julie is also a part-time Police Sergeant working as police prosecutor in Court 1 in Brisbane.

She's so concerned about the link between behaviour and food intolerance that she's undertaking independent study on the food effects on juvenile criminality as part of her Masters Degree in Justice/Law at QUT. Steve isn't sure that food turns kids into criminals but he does know what food can do to his son.

"He was like a bear with a sore head - that's how he was. He was aggressive to other kids and defiant to adults. Now he's responsive, his speech has improved, and his concentration span has improved.

"He can sit down and watch something on TV. He can sit down and do a puzzle or colour in."

Joseph's problem lies primarily with food colours and flavouring and reactions range from aggression to asthma. With careful shopping and label reading Joseph can enjoy and happy and normal life without too much imposition on the rest of the family.

There have been slip-ups on the way. The family dyed eggs for Easter not realising that Joseph's sensitivity would extend to touch. Joseph blames his mum for that asthma attack. The solution for Joseph came when a paediatrician suggested that Julie might like to read a book called "Fed Up" by Sue Dengate. She consulted a dietitian and put Joseph on an elimination diet. His life changed.

Julie is urging people who suspect food might affecting their children's behaviour to attend a presentation by Sue Dengate … - Julie's story (above) appeared on page 3 of the September edition of "Kids in Brisbane", resulting in a capacity crowd of nearly 200 for my presentation at Zillmere PCYC.
