Description

Bruno Calsa and co-authors show, in 2026, that feeding pregnant mice a low-protein diet leaves their offspring with weaker bones in old age. Poor nutrition before birth is known to shape later health, but effects on bone aging were not well mapped. Osteoporosis stems from failed bone renewal and crumbling internal structure.

Male offspring were examined at 12 and 18 months. Those from protein-restricted pregnancies had less spongy bone, lower mineral density and thinner outer bone by old age, and their thigh bones broke under less force. Microscopy showed more porous bone and disordered collagen fibers. Gene data pointed to a lasting shift in the bone immune environment, with more macrophage-linked signals and more bone-eating cell activity.
