Yeah, that's a Smart Choice...

Yesterday I had a hankering for a BLT.  Now, a good BLT requires real mayo; low fat or fat free just doesn't cut it.  So, imagine my surprise when I see that the Best Foods Real Mayonnaise has that "Smart Choices" icon on the label - the one with the green check mark.  As much as I love real mayo, I have to ask - is it EVER a smart choice?
