Hello Dr Sulieman

I looked at academic sources but could not find anything. However, there were non-academic sites that discussed milk and fish. I was about to conclude that there was no scientific explanation when I found this site. It is Jewish and mentions milk and fish and discusses the combination (end of 4th paragraph, and 5th paragraph).

This suggests that it reflects historic teachings that - I wonder - had reasons for this advice in the past? I would be most interested if any RG members can through light on the subject.

In the past, I remember reading 'Purity and Danger' by Mary Douglas. I seem to recall that the reason for historic cultural dietary customs were discussed, for example, those that were hygienically beneficial in past times.

Very best wishes

hello Dr. suleiman

I do not believe in it, I consider it a myth.My husband was very convinced, but he could not explain it scientifically.
