The BBC's excellent More or Less programme looked at the new alcohol guidelines on Friday. Although it didn't go into the statistical tricks of the Sheffield University team who devised the new 'evidence' (ie. theoretical model), it made several important observations, one of which is crucial and often overlooked.
It also included a revealing interview with alcohol researcher Jürgen Rehm who simply laughed when asked why the J Curve has attracted more scrutiny than any other finding in alcohol epidemiology. The answer, of course, is that it is a finding which many alcohol researchers find intolerable.
