Among all millets, finger millet (ragi) stands out as the most powerful for bone health, containing approximately 344 mg of calcium per 100 grams — the highest calcium content of any cereal grain and nearly three times that of milk. A meta-analysis published in MDPI Sustainability (2021) by Anitha et al. confirmed that regular finger millet consumption significantly improves bone mineral density, particularly in postmenopausal women, children, and the elderly.

Key Points

Finger millet: 344 mg calcium/100g — the highest among all cereals, essential for bone matrix formation

Finger millet also contains 408 mg potassium/100g, supporting calcium retention and reducing urinary calcium loss

Pearl millet provides phosphorus and magnesium, key cofactors in hydroxyapatite crystal formation in bone tissue

Sorghum (jowar) is rich in magnesium (165 mg/100g), which activates osteoblast activity and bone remodeling

Millets are naturally gluten-free, making them ideal for celiac patients who often suffer from calcium malabsorption-related bone loss

Citation / Evidence Base

ICRISAT nutritional databases and Springer Nature Food Production, Processing and Nutrition (2024) classify finger millet as a 'super cereal' for skeletal health, particularly in populations at risk for osteoporosis and calcium deficiency.
