For God's sake...!!

Anybody else fed up to the back teeth with these constant and contradictory articles about healthy and unhealthy food?  Saturated fat is bad for you - no it's not.  Red meat is bad for you - no it's not.  Alcohol is bad for you - not necessarily. And so on and so on.  They've demonised fat, sugar, caffeine, salt and all manner of other things at one time or another, only to later change their minds, and then sometimes change them back again!  What on earth are we supposed to think?  My Gran (yes, that one) used to say "moderation in all things" and once again I think she'd got it right.
