📊 Nutrition at a Glance
Reading spice numbers honestly: herbs and spices are measured per teaspoon, and a teaspoon of almost anything dried weighs 1-2 grams — so even a spice at a high per-100g concentration delivers a trivial oxalate load in the spoon most recipes use. The realistic way to use this table is for cooking frequency: a spice you shake daily deserves a lower number than one you toast twice a year. Garlic powder sits at 1 mg per teaspoon serving. Nearby entries in this category: Allspice (1 mg), Anise seed (1 mg), Basil (1 mg).
