Debunked risk factors

This table of debunked risk factors shows risk factors that some doctors used to point out to patients but have been disproven. Or there may still by doctors who continue to advise these as risk factors despite they are not. Feel free to show them the research that disproves that advice. And no, not all studies posted online are to be looked at skeptically, especially not when they are done by the truly leading authorities in the field. 
We also make sure that there are at least a couple of such studies shown, not just one. That way the evidence cannot be ignored as being merely incidental, anecdotal etc.
