So much of the Paleo science makes sense to me, and then I see [URL="http://www.youtube.com/watch?v=ktQzM2IA-qU&feature=youtu.be"]a clip like this[/URL] which gets me concerned. Shouldn't science be more black and white? I.E. Paleo is what works, or vegan is what works, or cotton candy is what works. Why are there so many conflicting studies and conclusions when humans are all basically the same?
I'm relatively new to this and appreciate any insight, thanks!
