Consumer Reports purchased large servings of fries from three Wendy's restaurants in Westchester County, N.Y., in early September. We sent the fries to an independent lab for fatty-acid analysis. We were surprised to find that the lab tests showed the fries contained significantly more trans fat than the 0.5 grams per serving claimed by Wendy's. To double-check the findings, we purchased fries from the same restaurants at the end of September and sent them to the same lab plus another independent lab for a second set of analyses, which confirmed our initial findings. The average amount of trans fat per serving was 2.5 grams.
