Trans fat doesn't taste particularly good, saturated fat does. Trans fats are used to cut corners financially--why buy butter if you can buy margarine cheaper?
"why buy butter if you can buy margarine cheaper?"
Tsk, tsk, tsk. Margarine is what you put on cheap biscuits. :) My wife is from farther north and jokes that we put a stick of butter in everything down here. Nothing cooks and tastes like real butter.
My point was, Wendy's isn't going to save anybody or have any significant inpact on anyone's life buy doing this. People eat more unhealthy foods at home than they do out, I'll bet.
