Then again, trans fats isn't the addictive high-margin industrial product... :(
Making a big show of banning one while letting the other run wild is very bad optics.
(Then again, I'm not sure how we might even go about curtailing sugars, they're just way too embedded in our culture.)
I get that, but I don't think the empirical science supports a claim that sugar is more costly than trans fats from a public health perspective; and certainly not that it's 1000x worse. In any event, the effects of sugar are indirect and complex. For example, AFAIU a high sugar but low calorie diet isn't particularly bad for you. By contrast, trans fats have a simple, clear, and substantial causal relation to arteriosclerosis.
50 years of prescribing partially hydrogenated oils and low-fat foods was based on poor, incomplete, and sloppy science. Going forward maybe we should instead base public policy on sound, concrete, reproducible science and straight-forward regulations. Not everything needs to be fixed with government mandates, and usually shouldn't without clear reasons.
Natural trans fats [1] are made by bacteria in the rumen, and are rather different than manufactured trans fats created from seed oils with hydrogen gas and catalysts.

> You're still probably better off with vegetable fats if you can help it, at least where partially hydrogenated oils are banned.
Most polyunsaturated oils are deodorized ("refined"), so customers don't realize they're eating rancid oil.
I bought unrefined grape seed oil years ago. Didn't know what to do with the obviously-rancid oil. Now I would give it to my father, so he could use it to help start his barbecue's charcoal.
That seemed to happen rather quickly, at least once the evidence became overwhelming. The FDA was only a few years behind major cities like San Francisco, though some European countries were way ahead of the curve.
Red meat and dairy have significant amounts of trans fats. You're still probably better off with vegetable fats if you can help it, at least where partially hydrogenated oils are banned.
