24 Nov 2016 --- The Grattan Institute is urging the Australian government to introduce a tax on sugary drinks that would see a 40 cents per 100 grams levy on all non-alcoholic, water-based drinks that contain added sugar - and the estimated AUD$500 million a year raised could be used in the fight against obesity. According to the recently published report, Australians are getting fatter with more than one in four adults now classified as obese, up from one in ten in the early 1980s. About 7 per cent of children are now obese and obesity is predominantly caused by people eating too much unhealthy processed food, often at considerable cost to their health and quality of life.
