Oxalate <25 mg/serving
Oxalate 25-99 mg/serving
Oxalate ≥100 mg/serving
Here's a rule of thumb that simplifies grocery shopping: white bread is low oxalate. Whole wheat bread is moderate oxalate. One slice of white bread runs about 1 mg oxalate. Two slices of dense whole wheat bread could be 20-25 mg. The fiber and bran in whole wheat is where the oxalate lives. For kidney stone patients tracking oxalate, white, sourdough, or rye bread are better choices than 100% whole wheat. This doesn't mean whole wheat is 'bad' — it means the oxalate content is higher, and you should account for it. For sandwiches and toast, white bread is your kidney stone friend.
