The only times I have ever bought salad dressing was when DH "required" Thousand Island, and I couldn't see making it just for him. After changing my own way of eating, I am working subtly on his, and now I do make his chosen dressing types. Salad dressing was one of the first things I learned to do in the kitchen; it isn't hard, and it doesn't take a lot of time. But yes, definitely, read those labels. You can't depend on them staying the same.
