Evidence based medicine?

From the BBC:

"Women should not drink any alcohol during pregnancy, NHS adviser the National Institute for Health and Clinical Excellence (NICE) has said.

It says if they must drink, they should not do so in the first three months and should limit consumption to one or two units once or twice a week afterwards.

It brings NICE in line with government advice and replaces previous guidance saying small daily amounts were fine.However, NICE concedes there is no evidence to support the change." [emphasis mine]

Have NICE employed "Doctor" Nick Fox of Capital Radio:

"Paedophiles have more genes in common with crabs than they do with you and me. It's a scientific fact - there no actual evidence for it - but it is a scientific fact"
