Hi Cryer:

I opt for the HFS bought salad dressing. The main thing to look for is that it uses expeller/cold pressed oil (and of course no sugar). According to Dr. S., that's OK. I'm taking a wild stab, but I would guess that Marie's is not appropriate. The type of dressing you want (that doesn't use damaged fats) will mostly be sold in a HFS (or the organic section of your grocery store).

HTH,
Wanda
