Overview
About Millet flour
Millet flour is millet ground fine, and it has been the backbone of gluten free flatbread in India and West Africa for far longer than it has been a health food aisle ingredient.
It is genuinely gluten free, with nothing on lactose, dairy protein, histamine, tyramine, caffeine, salicylates, sulfites, nitrites, free glutamates or nightshade. What it does carry is borderline nickel, mild fructans with a portion dependent FODMAP load, and mild oxalate. It also behaves nothing like rice flour in a mixing bowl: millet flour is thirstier, sweeter and grittier, so swapping it one to one for rice flour reliably produces something dry and crumbly. The other thing worth knowing is the thyroid question, because millet is the one grain with a real published goitrogen story, and milling changes the answer.

How Millet flour scores
Watch for
What trips people up
- Borderline nickel, the highest single mark on its profile. Millet is a small whole seed usually milled with the germ intact, and whole grain flours sit above refined starches on nickel. On a low nickel diet for systemic nickel allergy syndrome this is a flour to test rather than assume
- Mild fructans and a moderate overall FODMAP score that scales with portion. A spoonful thickening a sauce is a non event; a whole millet loaf in one sitting is a different exposure
- Millet carries C-glycosylflavones such as vitexin, which suppress thyroid peroxidase activity in the lab and are linked to endemic goitre in regions where millet is the staple. Two things soften this in flour: dehulling and milling strip the bran layers where those compounds concentrate, and cooking, fermenting or sprouting reduces them further
- Mild oxalate, and notably milder than our whole millet grain entry. Log the flour and the cooked grain as separate foods rather than assuming they carry the same load
- Borderline for low fermentation SIBO protocols, so treat it as a rotation flour rather than the base of every bake if you are on one

FAQ
Common questions about Millet flour
Is millet flour gluten free?
Yes. Millet is not a wheat relative and contains no gluten, so millet flour grades fully clean on the gluten criterion and is safe for coeliac disease on its own terms. The usual caveat applies: buy a flour certified gluten free if you are coeliac, because millet is often milled on shared equipment with wheat, barley and rye.
Is millet flour bad for your thyroid?
Not for most people, but the concern is not invented. Millet contains C-glycosylflavones that inhibit thyroid peroxidase, the enzyme that builds thyroid hormone, and populations eating millet as a staple with low iodine intake show higher goitre rates. Milling helps, because those compounds sit highest in the bran fractions that get removed, and cooking, fermenting or germinating the grain reduces them again. If you have existing thyroid disease and eat millet daily, discuss it with your clinician. Occasional millet flour in a bake is not a thyroid risk.
Is millet flour low FODMAP?
It is moderate rather than low, driven by mild fructans, so portion is the whole story. Small amounts used as part of a blend stay comfortable for most people. A bake made entirely from millet flour is where a sensitive gut will notice it. Rice flour and arrowroot flour both grade clean across every FODMAP group if you need a fully neutral base.
How does millet flour compare to rice flour?
Rice flour is the cleaner one on paper: it grades safe on nickel, on every FODMAP group and on oxalate, where millet flour is borderline on all three. Millet earns its place on flavour and protein rather than on tolerance, bringing a nutty, faintly sweet character that rice flour lacks entirely. In practice they are not interchangeable by weight either, because millet flour absorbs more liquid, so a blend of the two usually bakes better than either alone.
