Consuming a high protein diet and taking calcium and vitamin D supplements could help healthy older men and women increase total body bone mineral density (BMD).
Researchers from Tufts University in Boston, Massachusetts, United States, say they found no evidence that the type of protein — animal or plant — mattered: "BMD may be improved by increasing protein intake in many older men and women, as long as they meet the currently recommended intakes of calcium and vitamin D.
They add, "Further research is needed to determine whether a similar association would be observed in older adults consuming these nutrients from other sources."
A 20 percent higher protein intake in older adults supplemented with calcium and vitamin D is associated with favourable changes in total body BMD.
