Is millet high in sulfites?

Watch for

Graded E for oxalate, the highest band. This is the reason millet deserves a second look before it becomes your daily gluten-free grain, especially if you have a history of calcium oxalate stones / Millet contains C-glycosylflavones that inhibit thyroid peroxidase, the enzyme that builds thyroid hormone. The goiter link is documented in populations where millet is the staple calorie source and iodine intake is low, so the practical risk sits with staple-level intake plus low iodine, not with an occasional bowl / Gluten free by nature (graded A), but millet flour is frequently milled and packed on shared equipment with wheat. If you have coeliac disease, the certification on the bag matters more than the grain / Moderate on total FODMAPs (graded B), so a generous bowl of millet porridge or several bajra rotis can add up even though no single FODMAP subgroup is flagged / Graded E on the anti-inflammatory scale, meaning it lands on the pro-inflammatory side as a starchy grain. That is a dietary-pattern note rather than a chemical trigger, but worth knowing if you built your plan around anti-inflammatory eating
