Often, if you dig into the sources these types of articles you find incredibly specific research which has very little to with what the fluff piece is gushing positively about... and which is paid for by the industry it's not-so-subtly promoting. Often the industry backers have even done the study themselves, had their researchers write it up, and paid(!) some researcher at a publicly funded institution to add their (the researcher's) name to it and submit it to a journal. Rarely is it in any way clear that the study has actually been performed by industry groups/researchers with vested interests.

This is one of the (many) reasons you should be very skeptical of any of the "X is good for you!" type articles.
