📊 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. Barley Flour measures 14 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: Sorghum Flour (13 mg), Cassava Flour (19 mg), Tigernut Flour (12 mg).
