Why sources disagree on pear
The 2 studies here run from 1.8 to 6.6 mg per 1 medium pear, 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 178 g serving (1 medium pear). 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.
