Network Congestion Causes Dietary Restrictions?

I am currently at the 72nd IETF meeting in Dublin. There is a mailing list for all attendees (who sign up) to discuss meeting related issues. One of the threads on this list are dietary restrictions and the many combinations that exist among the participants and the challenges of finding appropriate food. After following some of the discussion, I am wondering whether the number of people with dietary restrictions at IETF meetings is larger than normal.

There was another popular topic at the beginning of the meeting concerning performance issues of the hotel network (which admittedly has seen some unusual amount of traffic). There were attempts to do rate limiting, which leads to second order effects (such as synchronization of congestion mechanisms of independent TCP streams).

I am wondering now whether there might be statistical evidence that perhaps network congestion leads to more dietary restrictions?
