A Griffith University study published in BMJ Public Health on Wednesday found a levy applied to non-alcoholic drinks with added sugar, such as soft drinks and most juices, could prevent 3.7 million cases of tooth decay, 191,000 cases of gum disease, and 115,000 cases of complete tooth loss across Australia over the next 25 years.
You don’t have to apply the levy to everything. The proposal the article is about is specifically “a levy applied to non-alcoholic drinks with added sugar, such as soft drinks and most juices”.
