IMO - would be good if J&L give us a hint like "We accept food known before X century A.D. in region Y". Or any date that seems reasonable for them. And this should be stickied in C&I rules.
This is a game after all, not historical reconstruction. So its up to devs to choose. We may have even stone age with TVs (like Flinstones) if the authors want us to

That can also be the 'rule' for posting the food ideas. 'We accept any food we like.' If Jorb writes that in sticky post - next time someone would try to blame you for posting modern food - you'll just shit them up with the link to Jorb's post
