People in their 20s and 30s face shorter lives because of poor diets, experts said. And today’s children could have even shorter life spans. Prof Jay Olshansky, of the International Research Centre for Healthy Ageing and Longevity, forecast that within 50 years the life span in Western countries could drop by up to five years.

Rob Moodie, professor of global health at Melbourne University’s Nossal Institute and a former VicHealth chief, said obesity in Australia was growing faster than in the US.
