The scientists warned parents not to replace breast milk or infant formula with the plant-based milk, after a case study revealed X-rays of an immobile infant in Spain.
The X-rays showed evidence of fractures in his legs, back and thinning bones.
The researchers determined to find out why the infant - 11 months - had such weak bones and immobility discovered he'd developed a rare case of scurvy after being fed a diet of formula mainly composed of almond milk for nine months.
Scurvy is a rare condition - once prevalent amongst sailors in the 18th century - characterised by a deficiency in vitamin C. The almond-milk formula was deficient in the vitamin and contributed to the fragility of the infant's bones.
