Kiwi scientists have been featured prominently in the media over the weekend discussing healthy diets and the role of sugar and genes in obesity.

“The Government seems allergic to regulation even when it is clearly supported by excellent science,” said Professor Doug Sellman, director of the National Addiction Centre at the University of Otago.

Meanwhile, thousands of Kiwi kids will be part of an experiment using breath tests to better understand the role of sugar in New Zealand’s high childhood obesity rates. Study leader, Professor Peter Shepherd of the Maurice Wilkins Centre, told the NZ Herald that while there was debate around how sugar was harming the health of children, there had been little research on the biological effects.

“We do know that there is a wide variation between individuals in the amount of fructose that can be absorbed from the gut into our bloodstream,” he said. “Those who are good at absorbing fructose are going to retain more of the calories from sugar in our diet than those who don’t absorb fructose well.”
