Unsolicited advice...

Hildietm

OK, so what do you guys do when someone offers you unsolicited advice on what you're eating, etc. I virtually got crucified today because I had a Lean Cuisine for lunch and should not be eating processed foods and high sodium while pregnant. Dude! It's one Lean Cuisine for lunch, buddy! Back off! Don't people know better not to criticize a pregnant woman? Especially for what she's eating?? Any witty comebacks for these situations?
