Golfers on the Juice?

I have two rather obsessive thoughts lately. One is whether or not a change in juice drinking habits could signal Type 1 or DKA. My daughter went from never drinking juice to specifically insisting that I buy it and drinking a up to a 1/2 gallon or more in a single day in the couple of weeks leading to her diagnosis. She specifically wanted juice, not necessarily water. This article caught my attention because Ray Allen's baby was also specifically asking for juice and it wasn't typical. I've heard this anecdote several different times. I wonder if it is truly a warning sign, in addition to general thirst. Warning signs are so important and maybe a caregiver seeing "one more" on the list would be prompted to quicker action.

The second quest for information was also promted by the article. The concept of a diabetes cluster totally freaks me out and yet does not seem implausible. If there really is an environmental trigger that sets off the latent genetic/auto-immune reaction, it stands to reason that it could affect multiple people in a small geography. I'm intensely looking for information on golf course proximity, as we lived for 2 years not more than 50 yards from a 15th hole and my daughter frequently played on the course at dusk. Any ideas out there?
