Flavor variants in a product family share the base profile, and the oxalate table follows the base more than the flavoring. Bran Grain (Bran 2) measures 30 mg per serving, in the middle of the family range. The useful reading is the family spread: if the range is narrow, flavor choice is free; if it is wide, the flavor with the lower measured value is the easy win. Related forms in this family: Wheat Germ Grain (24 mg), Quinoa Grain (Quinoa 2) (55 mg), Oat Bran Grain (22 mg).

โ“ Frequently Asked Questions

Can I eat Grain with kidney stones?

Proceed, but with awareness. Grain delivers 30 mg oxalate per 1 serving. That's moderate โ€” above the safe line, below the danger line. Portion size is your friend here.

How much oxalate is in Grain?

Quick math: 1 serving of Grain = 30 mg oxalate. 100g = 30 mg. Both numbers come from Harvard's latest lab measurements. Not AI, not a database, actual lab work.

Is Grain a high-oxalate food?

Moderate. Grain has 30 mg oxalate per 1 serving โ€” not high enough to panic, not low enough to ignore. Portions matter with this one.

What can I eat instead of Grain?

Plenty of options. Scroll down to Related Foods โ€” every ๐ŸŸข green item there is a lower-oxalate alternative to Grain. Same food group, way less oxalate.

How much Grain is safe to eat?

The portion math: 1 serving = 30 mg oxalate. Half serving = ~15 mg. With a 100 mg daily oxalate target, 30 mg from one food eats a big chunk of your budget. Go smaller.

How much sodium does Grain have?

Low sodium: 0 mg/100g. That's a non-issue for kidney stones. Just don't undo it by drowning it in salt during cooking.
