Agreed that the the poorest don’t consume trans fat—though I think the worry would be more that as countries get richer the problem gets worse, and you kind of want to nip the problem in the bud.
I find that one of the most useful heuristics when it comes to assessing whether a cause area is potentially >= GiveWell’s top charities, is looking at whether the problem is counterfactually solved by economic growth anyway (e.g. as countries get richer, sanitation/​nutrition/​access to healthcare improves, and stuff like malaria or diarrhoea becomes less of a problem) - not so for non-communicable diseases (or longtermist stuff like nuclear war, obviously).
