Is sumac high in oxalates?

Watch for

Moderate salicylate (C) is the one real flag. A restrained dusting over labneh is small, but fattoush and heavily sumac-crusted meat use it by the tablespoon, and that is where salicylate-sensitive eaters notice it / It is a downgrade from citrus, not a zero. Sumac still grades B as a histamine liberator, so if your histamine threshold is very low it belongs in the test-it-alone pile rather than the free-food pile / Ground sumac is very often cut with salt, and some brands add citric acid to sharpen the sourness. Check the label if you are tracking sodium or additives, because the filler can outweigh the spice / Zaatar is the most common way people eat sumac, and the mix brings company: thyme and oregano push the salicylate load higher, and most commercial blends contain sesame, which is a top allergen in its own right / Colour is a tell. Good sumac is a deep, dull brick red and slightly damp from its natural oils. Bright, uniformly scarlet powder usually means dye or a heavy salt cut
