"I've never heard of a link between coffee and diabetes, although I suspect that if you drink too much of it or use additives you could have a problem."

Rap, the Quack told me that something in coffee suppresses insulin production, but tea doesn't. Don't ask me about the chemistry/physiology involved - I'm an accountant and folkie, science is way too....errrrmmm, scientific......for me to understand.

If anyone knows better and can give me a link to some accredited data, I'd appreciate it as, since November 07, I only have half a pancreas, and I need all the help I can get! :-)
