Why does the safe threshold matter?
The 25 mg cutoff comes from clinical guidance for stone formers. Below it, a food's oxalate contribution is small enough not to move the needle for most patients. Harvard's 2024 lab data sits behind these figures — direct measurements, not estimates. For Lemon-lime soda (Sprite/7Up), the measured oxalate value is 0 mg per 12 fl oz (Safe).
Can I eat this food every day?
For Safe foods (under 25 mg/serving), daily use is generally fine. Caution and Avoid foods work better as occasional items — rotate them with safer options so no single high-oxalate food becomes a habit. For Lemon-lime soda (Sprite/7Up), the measured oxalate value is 0 mg per 12 fl oz (Safe).
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. Applied to Lemon-lime soda (Sprite/7Up): 0 mg oxalate per 12 fl oz — Safe per Harvard (2024).
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. For Lemon-lime soda (Sprite/7Up), the measured oxalate value is 0 mg per 12 fl oz (Safe).
