🥜 Nuts & Seeds
Browse nuts and seeds. Based on Harvard T.H. Chan SPH oxalate data (2024).
51 foods in this collection
Nuts and seeds are the highest-oxalate snack category in the database. Almonds measure around 107 mg per quarter-cup — above the avoid threshold — while walnuts and cashews sit in the moderate range, and chia, sesame, and poppy seeds climb higher still. The trap is that nuts read as 'healthy food,' which makes the oxalate load easy to overlook. The stone-aware pattern: treat nuts as a measured treat rather than a free snack, keep servings to a small handful, and pair them with dairy or another calcium source in the same sitting.
