Why does the safe threshold matter?
The 25 mg line is the reference point clinicians use to separate everyday foods from ones that need caution. Every value on this page traces back to Harvard's 2024 lab analysis, so the threshold is applied to measured data rather than estimates. Jellies, Jams or Preserves, Orange Marmalade comes in at 10 mg oxalate per 1 tbsp (Safe) in the measured database.
Can I eat this food every day?
Daily eating is fine for Safe foods (under 25 mg/serving). For Caution or Avoid foods, spread them out and alternate with low-oxalate picks. The idea is keeping your weekly oxalate load manageable, not eliminating any single food. Applied to Jellies, Jams or Preserves, Orange Marmalade: 10 mg oxalate per 1 tbsp — Safe per Harvard (2024).
Where does the oxalate data come from?
Harvard T.H. Chan School of Public Health (2024) via the OHF database. These are direct laboratory measurements — the most reliable oxalate data available for food. For Jellies, Jams or Preserves, Orange Marmalade, the measured oxalate value is 10 mg per 1 tbsp (Safe).
Should I also check sodium and calcium?
Yes — oxalate alone doesn't decide stone risk. Sodium pushes more calcium into urine, and calcium from food (not supplements) helps bind oxalate during digestion. The main food page covers sodium and calcium alongside oxalate. Applied to Jellies, Jams or Preserves, Orange Marmalade: 10 mg oxalate per 1 tbsp — Safe per Harvard (2024).
