Finger Millet Flour (Ragi Flour)

About

What it is and where it shows up.

Ragi flour is a whole-grain flour milled from finger millet (Eleusine coracana L. Gaertn.), a cereal crop domesticated around 5000 BC and widely cultivated across India and Africa. It is prized for its exceptionally high calcium (≈0.38%), dietary fibre (≈18%), and polyphenol content (0.3–3%), and is used in traditional preparations such as roti, mudde (dumplings), ambali (thin porridge), and malted weaning foods.

Safety summary

The regulatory and scientific consensus.

Ragi flour is a traditional whole-grain food with a long history of safe consumption and no ADI or maximum-use restrictions imposed by any major regulatory authority. It contains anti-nutritional factors—tannins, phytates, and polyphenols—that can reduce mineral bioavailability when consumed in large quantities without processing; soaking, malting, or fermentation significantly reduces these compounds. Individuals with thyroid disorders should exercise caution, as millets contain goitrogenic C-glycosylflavones, and those with kidney disease or oxalate-stone history should seek dietary advice due to the grain's moderate oxalate and potassium content.

Regulatory landscape

What food-safety regulators have decided.

Jurisdiction	Status	Note
FSSAI (Food Safety and Standards Authority of India) (India)	Approved	Gazette Notification (10 May 2018) under FSS (Food Product Standards and Food Additives) Amendment Regulations specifically notified updated quality standards for Finger Millet (Ragi). Ragi is also explicitly classified as a conventional cereal/botanical food and is excluded from nutraceutical or health-supplement categories under FSSAI regulations.source

Who should approach with care

Whose guidance would steer them away.

Thyroid Disease — Finger millet and other millets contain goitrogenic C-glycosylflavones that may interfere with thyroid hormone synthesis, especially in iodine-deficient individuals; those with existing thyroid disorders should moderate unprocessed ragi consumption and consult their physician.

Kidney Disease — Finger millet contains moderate levels of potassium, phosphorus, and oxalates; patients with chronic kidney disease (CKD) or a history of calcium-oxalate kidney stones should seek a dietitian's guidance before regular consumption.

Infants — Whole (unprocessed) ragi flour contains anti-nutritional factors — tannins and phytates — that reduce mineral bioavailability; as documented in PubMed reviews (PMID:37970380), infant weaning formulations should use malted or fermented ragi flour where these compounds are substantially reduced.
