Why does oxalate per 100g matter?

It lets you compare apples to apples on oxalate density. For Semolina flour, the measured oxalate value is 1 mg per 1/4 cup (Safe).
How accurate is the oxalate measurement?
The measurements use ion chromatography, the accepted reference method for oxalate. That means real lab values for each food rather than inferred numbers. Some natural variation exists between samples, but this is the strongest published data set. For Semolina flour, the measured oxalate value is 1 mg per 1/4 cup (Safe).
How does this compare to other foods?
Anything under 25 mg per serving is Safe; 25-99 mg is Caution; 100 mg or more is Avoid. The category pages on OxalateWatch list foods side by side, so you can see where this one ranks. For context, Semolina flour measures 1 mg per 1/4 cup, rated Safe.
