Prof. Timothy Noakes describes the methodology and findings associated with Ancel Keys’ two most famous studies, the Seven Countries Study (SCS) and Minnesota Coronary Experiment (MCE). Significantly, both studies failed to support Keys’ diet-heart and lipid hypotheses. Noakes claims Keys and his followers, to hide the inconvenient truth, buried the studies’ results. To the detriment of Keys’ legacy, however, the original MCE documents were discovered in a box five years after his death. Noakes explains what the data revealed.
