Agreed. The "correlation != causation" mantra does not match the context here.
It's true that correlation studies are not as conclusive as laboratory experiments in general, but when we're talking about negative long-term health effects on humans, you can't establish causation without doing something unethical. But does that mean science becomes useless? I don't think so.
There are times when it's appropriate to infer causation from a correlation and act on that conclusion. For example, the famous lead toxicity studies are correlation studies. One such study, cited over 1000 times, [0] meets only 6 out of 9 criteria for inferring causation [1], and people are comfortable making that inference.
A good next step would be to go through the PowerWatch list of studies [2] and evaluate these studies based on these criteria (or a similar list).
