There is no scientific fraud with the diet recommendations. The problem is that many physicians--most of whom are *not* trained in research--do huge studies and crunch megabytes of data to come up with correlations. And they make the mistake of thinking that finding a correlation proves something, when it only indicates that more research is needed.
Yeah, the real fraud is in the education system that teaches them that "P" stands for "proof".
If it were only being weak in statistical analysis, committing the common error of confusing correlation with causation.
Just like in AGW, when a data set doesn’t conform to the preconceived notion of the researchers, it’s tossed out. Worse yet, when the research indicates the opposite of the politically correct prevailing wisdom, the politically correct prevailing wisdom is still what’s advertised.
Read the Taubes books to see the Lysenkoism in much of the nutritional research. I stand by the use of the term fraud.
