Why sources disagree on cantaloupe
Both studies here put it at 1.6 mg per 1 cup cubed, measured between 2002 and 2023.
Where this number comes from
Each row is one published measurement, converted to a 160 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.

* The study measured soluble oxalate only, which understates the total, so it's shown but doesn't set the grade.
