❓ Related Questions

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 context, Soy Yogurt measures 5 mg per 6 oz, rated Safe.

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 Soy Yogurt: 5 mg oxalate per 6 oz — Safe per Harvard (2024).

Where does the oxalate data come from?

The numbers come from Harvard T.H. Chan SPH's 2024 laboratory measurements, published through the OHF database. Direct lab analysis, which is why they're treated as the reference values for food oxalate. Soy Yogurt comes in at 5 mg oxalate per 6 oz (Safe) in the measured database.

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 Soy Yogurt, the measured oxalate value is 5 mg per 6 oz (Safe).
