As I said, I look at other things as well. Someone mentioned high fructose corn syrup--that is one I look for too. It is amazing how many things they put that in now. I also look at the origin of the product, as LAJ does.
I agree with Andy, what I look for often depends on what the product is. And, like Andy, I look to see how much of something is in a product. I'm glad they started listing the ingredients ranked from the highest content to lowest.
I always check the labels of anything that says low-fat or reduced fat, to see what they are replacing the fat with. Usually it is sugar. I am trying to reduce the sodium in my diet, but
I hate the flavor of "No Salt Added" canned vegetables. They just taste flat to me. I either buy fresh, frozen, or regular canned.
