I don't buy ice tea when I do fast food.  On occasion I will get an ice tea- lemonade mix. Fast food ice tea generally contains Propylene Glycol Alginate.  It's a food emulsifier.  It's also is used in anti-freeze and runway de-icer at the airport.  I found a list of the 50 unhealthiest foods on msn.com.  Unfortunately, I eat a lot of them.  Fast food chicken nuggets...
