Researchers unearthed more evidence that replacing butter with vegetable oils does not decrease risk of heart disease
...
Using the recovered data to perform analyses that had been pre-specified by the MCE investigators but never published, the team confirmed the cholesterol-lowering effect of the dietary intervention. But they also found that in the recovered autopsy records, the corn oil group had almost twice the number of heart attacks as the control group.
Perhaps most strikingly, graphed summaries contained in Broste's thesis indicated that in the intervention group, women and patients older than 65 experienced roughly 15 percent more deaths during the trial, compared to their control group counterparts.
