🔍 Key Insights

1 **Mostly safe territory.** 16 out of 20 foods (80%) in this intersection fall in the safe oxalate range (under 25 mg per serving). That's good news — you have plenty of low-oxalate options here.
2 **Big oxalate range.** The spread is 0 to 114 mg per serving — a 114 mg difference. Best pick: **Seaweed** (0 mg). Most caution needed: **Seeds** (114 mg).
3 **Low average oxalate.** The mean across all 20 foods is 16.2 mg per serving — solidly in the safe zone. You can build meals around these foods with confidence.
4 **Sodium alert.** 17 foods in this intersection are high in sodium (460+ mg/100g). Excess sodium increases urinary calcium — a known kidney stone risk factor. Check sodium levels alongside oxalate when choosing.
5 **Calcium benefit.** 5 foods (29%) provide 100+ mg calcium per 100g. Dietary calcium binds oxalate in your gut — getting enough calcium from food is actually protective against kidney stones.

The foods listed below all satisfy both conditions, making this a focused set of 20 items.

Are Plant-Based foods that are High Sodium safe for kidney stones?

The short answer: some are, some aren't. 80% of the foods in this intersection fall in the safe range. The rest need more attention. The key is picking the right specific foods — check the verdict indicator on each card below.

How should I use this Plant-Based × High Sodium breakdown?

Start by scanning the safe foods (🟢) — these are your staples. Then note which foods are in the caution or avoid zones so you know what to moderate. If you're meal planning, build around the lowest-oxalate options in this intersection and pair them with calcium sources (yogurt, milk, cheese) to blunt oxalate absorption.
