Noone is saying that blaze. Its just that we know that trans fat is unhealthy, but we don't know how unhealthly it is yet. Possibly eating ANY quantity of trans-fat could be bad for you, because theres a heck of alot more health problems now than there used to be before hydrogenation started, so you never know.
Thats like saying its ok to use rat poison in the fries without telling you, because you should know that they arent good for you.
