It strikes me as I am learning Kesubos that the Gemara takes the time to speak of extensively the shortcomings and praises of dates (the fruit). I know the gemara does the same with cabbage and other fruit and vegetables like watercress and the like. What does the gemara wish to accomplish by giving this information if anything, what is the significance, and is there a significance to its placement to this information? Or is the gemara just plain old giving food and health advice?
There might be a few possible reasons:
This is all on a simple peshat level. No doubt there are also deeper Kabbalistic and other reasons for this information being included in the Gemara, although I don't know of any.
