My mom asked me about SmartBalance once, if it was OK for her to eat. I told her no, just to be safe.

If they break chemical bonds to make it a solid, then it's a margarine and should not be eaten. If they emulsify it some other way, without heat, much the same way you can whip cream and make it more solid, then I suppose it's OK. I just haven't found anything about how it's actually made. And I learned a long time ago not to trust what the maker of the product says.
