Not only do we eat too much meat, but I suspect things like bread and pasta would also not have been eaten until farming developed.
Who would want to go through the laborious process of preparing something like wheat, when easier foods to prepare could be had ready to eat raw right off the tree?
I also suspect that bread and pasta are bad for teeth; if so, that would be further proof we should not be eating such things.
Well, breads were eaten commonly in biblical times, so I have to disagree with you there. As for pasta, I know nothing of the history of pasta; I know Indian cultures often ate ground corn items (e.g. tortilla type foods).
I think whole-grain breads are best and can be eaten daily.
