📊 Nutrition at a Glance
Flavor variants in a product family share the base profile, and the oxalate table follows the base more than the flavoring. Chestnut Flour measures 10 mg per serving, in the middle of the family range. The useful reading is the family spread: if the range is narrow, flavor choice is free; if it is wide, the flavor with the lower measured value is the easy win. Related forms in this family: Tapioca Flour Flour (9 mg), Cornmeal Flour (10 mg), Oat Flour (8 mg).

What's the oxalate content of Flour?
The lab result: 10 mg per 1/4 cup (21g serving). That's 49 mg per 100g. Harvard's ion chromatography analysis, 2024. Not crowdsourced, not estimated.
Is Flour low or high oxalate?
It's low. 10 mg per 1/4 cup is well under the 25 mg danger line. Flour is not the food you need to worry about.
