📊 Nutrition at a Glance
Spices are the one food family where serving size dominates the oxalate question completely. At a gram or two per teaspoon, the difference between spice entries matters less than how often the jar comes out of the cupboard — a daily-seasoning spice and a holiday-only spice are different exposure categories even at similar per-serving numbers. Celery seed measures 1 mg per teaspoon serving. Nearby entries in this category: Allspice (1 mg), Anise seed (1 mg), Basil (1 mg).
