HaLeivi:The source of the Sakana is not from Chazal. It is from the 14th century doctors. There is no reason that I have to take their musings into consideration.
First, you think that if you repeat yourself assertion that it’s all based on 14th century doctors then you can throw everything out. If the Bet Yosef (16 century as you like to ignore) took their musings into consideration, then you shall also. Saying that you don’t have to even to consider that it might be unhealthy without consulting with modern doctors is just downright disrespectful to the biggest Posek of the world.
You really missed the point.
I really think you did. You are grabbing at thin air to try to create a new kula. That even though you don’t have a clue what modern science says about fish and dairy, you can automagically assume that there is evidence to back you up.
