Hello All,

This delightful fruit (for most of us) is generally very high in oxalate
and low in calcium, so the oxalate is well absorbed. Consequently, it is
not a good food for those predisposed to oxalate kidney stones and
especially not for people with compromised kidney functions.

Here are the links to a couple of newspaper articles we wrote about this
commonly consumed fruit in Hawaii:

Kidney patients should avoid star fruit

Oxalic acid in star fruit can kill kidney patients

Aloha,

Alan
