Interesting. In my case, I'm "calcium-absorptive", meaning I have to keep calcium intake as close to zero as possible.
I asked my kidney surgeon about taking a calcium blocker, but he said not in my case.
(He's not the guy in the office with an interest in Porsches, laugh2)
So far, 5 years without dairy, broccoli, green veggies, ice cream, chocolate, tea, etc has kept that issue at bay.
Not always fun - I'd love a good Chicago-style pizza and a salad - but better than the alternative !

Drink your water, kids !
