It's an incredibly important distinction, though. In a lot of these studies, there's just survey data, which isn't reliable, as has been pointed out. If I said that I got fat because I was eating candy and salad at the same time, you might draw the conclusion that it was the candy making me fat. But if the amounts and ingredients weren't specified, the researcher might not know that I ate a salad with a cup of blue cheese dressing, and only one Reese's mini peanut butter cup. The caloric values are very, very different.
