Agreed! Though in terms of both evidence base and tractability, I would say tobacco > soda > salt—we’ve done a lot more tobacco taxes than SSB taxes, which in turn is far more common than sodium taxes (or taxes on high salt food). That is consequential for (a) whether we have empirical data to inform our cost-effectiveness analyses and general prioritization, and (b) whether we can persuade policymakers, who care a lot about whether other countries have done something (and successfully).
