While I don't disagree that omega-6 oils are suspect - especially when heated/reheated - the evidence for sugar being bad for you is still far greater than the evidence that seed oils are bad for you. The US State system lends itself to natural experiments so I'm all for iterating on what taxes incentives actually lead to the desired outcomes (higher healthspan and lower healthcare costs). There very well could be multiple contributing factors to the epidemic- generically if the behavior increases chronic disease burden on the population it needs to be disincentivized via taxes so that you can incentivize moving to alternatives without the negative externalities.
