More petroleum in food?

My friend and fellow food dye avoider called me to say she noticed Heinz advertising on their vinegar that they are the only one guaranteed not to contain petroleum. WHAT!? Now it's in the vinegar too?! I did a quick Internet search and found this article about vinegar and petroleum. Once again, it pays to know what you are eating. Something else to ponder, I guess.

By the way, I think the vanillin (another petrochemical) in the easter chocolate has been affecting me this week. Maybe that's why my daughter is a little on edge too.
