The most recent of those articles is dated 1994, which tells me that whatever they were looking at failed to pan out upon further investigation. Also, since I don’t feel like looking up all those references in PubMed, I can’t see the authors, which would tell me whether those studies were conducted independently, or by an author or two with an agenda.
It is not unusual for studies to seem to show a phenomenon that turns out not to be valid upon further examination.
After reading hundreds of studies, I would say that many of them (regardless of the subject) are deeply flawed. Not in their observations, but in their conclusions, which often appear to be bias-driven interpretations rather than solid conclusions based strictly on the data.
For example, how often do we hear now that consumption of sodas causes obesity? Study after study shows a real correlation between soda drinking and obesity. Nevermind that a pattern of overconsumption leads to both the high quantity of sodas consumed and the obesity; because of the correlation, we are to believe that sodas cause obesity. Why not assume that obesity leads to high soda consumption, another conclusion equally supported by the data?
Then do your own studies and research. Oh wait, you’ll just tell us you “don’t feel like” doing it. Never mind.
Sheesh, go enjoy your bon bons, ma’am.
I apologize for the bon bons comment. Please forgive me for that.
