I personally have a problem with sponsored parties doing "Scientific Studies" of different brands and types of products...and then playing it off as an independent article.Call me a cynic, and I'll even own up to it, but I just can't shake the thought that those conducting the"experiment" could have possibly designed the"experiment" specifically to highlight a desired outcome. NOT AN ACCUSATION, merely an expression of a fear.
In the scientific community it would not be considered independant research. The author would have to attach a disclaimer stating that he had a vested financial interest in the company. Were he trying to publish this as science the reviewers would have thrown it away. It is an advertisement/propaganda.
Anyone that has published a scientific paper in a peer reviewed journal would find the said claims quite amusing.
