You got that right Pat ... and what you said applies to everything out there that is being "sold" on statistics, research projects, studies and the like ...

I even found this happening on another subject, where a research project was used to "sell the concept" and the university web site on the study said the same thing as the "commercial" but a few months later I was in that university's area and went to their library and read the hard copy - half the facts were left out on the web site and the "commercial". When I checked who funded the research project - it was the industry that was trying to "sell it's concept" that this particular project "proved" them correct.

I would add "Who funded the study?" As an example; if it was a study on milk allergies funded by the American Dairy Association, the results might be different than if the study was funded by an independent agency. The results would also be different if the study was funded by a competitor of the dairy industry.

Don't forget that statistics can be made to say just about anything one wants. So if statistical data is in the article, be sure to look for variances of error figures.

Common sense plays a good role too. We humans have yet to invent a single food item and or pill that will cause us to loose weight regardless of how much else we eat or do or don't exercise.

So be careful of claims of that nature. Just about anything in moderation will not hurt you unless you are deathly allergic. Moderation being the key.
