Flavor variants in a product family share the base profile, and the oxalate table follows the base more than the flavoring. Teff Flour (Teff) measures 75 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: Amaranth Flour (74 mg), Buckwheat Flour (84 mg), Teff Flour (Teff 2) (66 mg).

❓ Frequently Asked Questions

Can I eat Flour with kidney stones?

Yellow zone. 75 mg per 1/4 cup means Flour sits in that middle ground where it's manageable but not risk-free. Half portions help. So does eating it less often.

What's the oxalate content of Flour?

75 mg — that's the oxalate in a standard 1/4 cup of Flour. For the 100g comparison freaks: 222 mg. Source is Harvard's 2024 food analysis project.

Is Flour low or high oxalate?

Moderate. Flour has 75 mg oxalate per 1/4 cup — not high enough to panic, not low enough to ignore. Portions matter with this one.

What are the best low-oxalate alternatives to Flour?

Substitutes exist. The safe alternatives listed below are all low-oxalate foods in the same family as Flour. Grab one of those and you dodge the oxalate while keeping similar flavors.

How reliable is the data for Flour?

The 75 mg oxalate figure is direct from Harvard's lab — measured, not estimated. The sodium/protein/calcium numbers aren't fully matched yet. When they are, we'll update.

How much Flour is safe to eat?

Think garnish, not main dish. Flour at 75 mg per 1/4 cup is a lot for one food. Use smaller amounts spread across meals or as a flavor accent rather than the centerpiece.
