I agree, reminds me of a line: ". . . thou dost protest too much."

The question in all this, as I no longer care whether there was a conspiracy or not, is how much rigor was applied to these studies to enable the conclusion to be any more than a rough correlation? In a dietary study, how does one isolate sugar or fat to determine either one is a root cause for specific health problems? It can be done, but it would be a very complex study requiring long-term cooperation of the subjects. Not easy to do. In addition, there likely would be an array of confounders that render a factual result impossible to attain.
