High Levels Of Dietary Vitamin K Linked To Improved Bone Density In Elderly Men And Women

A study by Spanish researchers has found that a diet rich in vitamin K found in leafy vegetables such as lettuce, broccoli and spinach, and also from dairy and meat, is associated with increased bone mineral density (BMD) in both elderly men and women. The study included 200 elderly people “with healthy dietary habits” whose bone density was measured using quantitative ultrasound assessment (QUS). The researchers found that for every 100 microgram increase in vitamin K intake there was a 0.008 g/m2 increase in BMD. “High dietary vitamin K intake was associated with superior bone properties,” the researchers concluded.
