Like this one and others, there are studies that say it has both positive and negative impact.
I guess what concerns me (or impresses in some cases) more than the reports is the contrasting findings from one study to the next. Not only that, the same isomers that are proported to be positive for one thing are proported to be negative for another.
What do you attribute the obvious contrasting reports? Marketing, anti-cla propaganda, misinformation, bias, etc.?
Thanks for the information.
