Most studies look at consumption of fats in a vacuum. The study may not have looked into other dietary and activity inputs that led one group to have better health than the other. This could indicate that saturated fats are not a causal factor but was a indicator or trouble groups. If all the groupls ate similar with the exception of the fats and particiapated in similar physical activities and these controls were documented these studies w ould have scientific merit. Without controls the study is simply correlative and weakly at that.
