Thank you so much for this query.
I am sorry hear about what you have been experiencing.
From the information you have provided, the pinkish water is most likely related to the intake of beets. This is even more true because it has consistently happened each time you consume beets. if it were a recurrence of the crohn's disease, I am pretty sure you would have had constant symptoms irrespective of what you eat. Also, having no other symptoms with a last colonoscopy
which was entirely normal make the above thoughts very correct.
I hope you find this useful and informative. If you have more questions, please ask us and we shall gladly provide answers. I wish you good health.
