Shows potential.

This really looks promising. Cashews are healthy (unless you're allergic, of course, in which case...) but the amount you can get in your diet won't duplicate the results of this study. You'd end up with a tummy ache if you ate enough to have the effect needed.

Please note that this is a preliminary study. I'm sure more research will be coming PLUS Big Pharma will soon be busy producing a drug(s) to produce the anti-diabetic effect. Personally, I'll opt for using the extract. Shouldn't be side effects with the extract, although, as with anything, research and tread carefully. This is your only body so you need to be careful what you put in it.
