Soda without the listed preservatives

43 of the 43 soda foods on the list pass this check. A short, fixed list: BHA, BHT, TBHQ, potassium bromate, brominated vegetable oil, propylparaben and azodicarbonamide. Other preservatives, such as citric acid or sorbates, are not counted.

They may still fail one of the other four checks; the strip on each card shows which.
