🚨 High Sodium Alert
Pepper contains 2643 mg sodium per 100g — well above the recommended limit for kidney stone patients. High sodium intake can increase calcium in urine, raising stone risk.
Cooking method is the axis that separates the members of this family. Boiled versions shed part of their soluble oxalate into the discarded water (typically 30-50%), raw versions retain everything, and frozen sits close to raw. Pepper (Sweet and Hot) measures 15 mg per standard serving, at the high end of the family — check the form you actually eat rather than the base name. Related forms in this family: Pepper (Sweet and Hot 2) (11 mg).
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. Pepper (Sweet and Hot) measures 15 mg per teaspoon serving. Nearby entries in this category: Tea (Herbal) (14 mg), Ginger Herbs and Spices (Ginger 3) (17 mg), Lemon Peel Herbs and Spices (13 mg).
