Is pineapple high in oxalate?
No. Low, 9.1 mg per 1 cup chunks
Range 8.1 to 10 mg across 2 studies, 165 g serving
Pineapple is low in oxalate: about 9.1 mg per 1 cup chunks, which is 18% of the 50 mg a day many stone clinics aim for, or 9% of the 100 mg others allow.

Why sources disagree on pineapple
The 2 studies here run from 8.1 to 10 mg per 1 cup chunks, measured between 2002 and 2023. They tested 2 preparations, and growing conditions, variety and lab method all move the number.
Where this number comes from
Each row is one published measurement, converted to a 165 g serving (1 cup chunks). 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.
