A newly released review from Otago University shows there's a direct correlation between the amount of tax imposed and a drop in the consumption of sugary drinks: finding for instance a 10% tax has reduced the purchase and consumption of sugary drinks by 10%.

The study looks at the effects of imposing a sugar tax in four American cities, the Catalonia region of Spain, and country-wide in Chile, France and Mexico.  Kathryn Ryan speaks with lead author Dr Andrea Teng, a public health physician and senior researcher at the University of Otago.  The review has just been published in international scientific journal, Obesity Reviews.
