This is a study published 12 April 2016.
It is REALLY important as it revisits a hugely influential experiment 48 years old - The Minnesota Coronary Experiment (1968-73). The original study was hugely influential in establishing the current paradigm we in thrall to today - saturated fat will kill you.
I'm posting this not to bolster my well known stance re diet and health (I guess it does though), but to underline how careful you (and I mean you) have to be when interpreting data when researchers are looking for confirmation of what they know to be true and the impact can be catastrophic or remedial.
