Is Ham (Sliced) Safe for Kidney Stones? (Safe)
mg oxalate
per serving
Serving: 3 oz (85 g)
Verdict: 🟢 Safe
Per 100g: 0 mg
Data: Harvard T.H. Chan SPH (2024)
Here's the takeaway: Ham (Sliced) earns a Safe rating (🟢) at 0 mg oxalate per serving. Being under 25 mg means it fits comfortably in everyday eating. Keep your usual habits — adequate fluids and calcium in meals — and Ham (Sliced) poses no special concern.
Putting Ham (Sliced) in context: it lands well below the category average of 6 mg. In the database, 89% of meat & poultry (68 of 76) fall in the 🟢 Safe group (under 25 mg oxalate/serving). The typical meat & poultry here averages 6 mg oxalate per serving, so Ham (Sliced) runs 100% below that baseline. That places it among the lower-oxalate options in its category. Why this matters: the gap between two Safe foods can be wide — one may hold 5 mg oxalate while another sits at 24 mg. The lower one leaves more room in your day.

Why does the safe threshold matter?
The 25 mg per serving threshold is based on clinical guidance for kidney stone patients. Harvard's lab data (2024) provides the most reliable oxalate measurements available — no database estimates, direct lab analysis. For context, Ham (Sliced) measures 0 mg per 3 oz, rated 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. Applied to Ham (Sliced): 0 mg oxalate per 3 oz — 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 context, Ham (Sliced) measures 0 mg per 3 oz, rated Safe.
Should I also check sodium and calcium?
Yes — kidney stone risk isn't just about oxalate. High sodium increases urinary calcium (a stone promoter). Adequate dietary calcium (from food, not supplements) actually binds oxalate in your gut.
