0 mg50 mg = a day60 mg+
Papaya is low in oxalate: about 1.9 mg per 1 cup cubed, which is 4% of the 50 mg a day many stone clinics aim for.
Boiling and draining lowers oxalate, because the soluble part leaches into the water. Compare the raw and boiled rows below.
Where this number comes from
Each row is one published measurement, converted to a 145 g serving (1 cup cubed). The grade and the range use the rows prepared the way the serving is eaten, and take the middle. How the grades work.
