23 Jun 2020 --- Tiered fixed sugar tax designs can produce substantial health gains, as well as lower health costs in the US, according to a simulation model of different designs of taxes on sugary drinks. The study was carried out by Tufts University researchers in Boston, US, and published in the American Heart Association (AHA)’s flagship journal Circulation. The findings point to the importance of considering different sugary drink tax designs in any new local, state and federal efforts to improve health outcomes and save health care costs, the researchers note.
