I drink it the way the Brits do...with a splash of milk**...(2% or full fat***)
And the milk offsets the oxalate in black tea which (in large amounts) can cause kidney stones.

Tea with milk better for you than tea without milk
Also I eat mostly low oxalate foods (except for Oreos, but if you dunk them in milk then it's OK
)
So far no problems.... knock on (what else?) wood.

**Except when I'm sick, and the thought of consuming
any dairy makes me gag.
So I put rum or brandy in the tea instead.
*** I also learned from my Brit roomie that you don't put cream in tea...it's always milk.
Cream is so "flavor heavy" that it overwhelms the flavor
of the tea.
