I have a specific question.

He says in Romans 14:20-23:
All foods are clean, however we are to try to not eat meat?
I understand in this context its about not letting another fall into sin, but there is a reason why the word choice is meat (and wine).
I also understand in the old testament we are not to eat unclean animals however we are under the new testament.
Thoughts on this and on meat in general, perhaps?
