In practical terms, Spouts is a low-risk food for kidney stone patients. Its 4 mg oxalate per serving stays under the 25 mg line, so it can appear in your regular rotation without extra calculation. As always, staying hydrated and getting dietary calcium supports stone prevention.
Among legumes, Spouts sits well below the category average of 20 mg. For context, 44 out of 60 legumes (73%) are rated 🟢 Safe (under 25 mg oxalate/serving). The average legumes in our database has 20 mg oxalate per serving — which means Spouts is 80% below the category norm. Within its specific category, Spouts ranks among the lower-oxalate options. This context matters because two 'Safe' foods can have very different oxalate levels — one might have 5 mg while another has 24 mg. Both are Safe, but the first gives you more dietary flexibility.

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, Spouts measures 4 mg per 1/2 cup, 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. For context, Spouts measures 4 mg per 1/2 cup, rated 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. For Spouts, the measured oxalate value is 4 mg per 1/2 cup (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.
