Chris Ramsden's re-analysis of the Minnesota Coronary Experiment data suggested a higher incidence of coronary events in some individuals consuming a high polyunsaturated fat diet.

“Ramon went and published all of these data plus a whole bunch of subdata as I said just a few years ago I believe in the British medical journal and I actually found something that was that threw a wrench in my initial hypothesis my initial view of the Minnesota Corner experiment was it probably wasn't a long enough intervention it might be that 5 years was not long enough to appreciate a difference and so it was underpowered or Too Short in a duration to see a benefit if there was a benefit but in Ramon's analysis you actually saw the opposite because he now looked at some subgroups and you actually saw a higher incidents of coronary events in some of the people that were consuming the high polyunsaturated fat diet”
