There's just way too many conflicting studies on CLA at the moment, that concentrating on just one study is quite erroneous.

One says it's bad for IS, next one says it's good. One says it's bad for CVD risk factors, next one says it's good. Etc. etc., the big picture on CLA is still totally messy. Anyone seen a good meta-analysis on current CLA studies yet?

As a side note: considering CLA has probably existed a loooong time (enzymatic creation method, enzymes are shared a long way back "in history", even cross-species sharing is very usual), and that the human body can create one CLA isomer from trans-11 fatty acids, I remain smack dab on the fence, but I have to confess am a bit tilted on the "maybe it has good effects more than bad" side. ESPECIALLY since contrary to the glucose homeostasis question, the cancerous issue re CLA is much less controversial: lots of studies pointing at possible antitumorgenic effects of CLA already exist.
