Bone health

There is evidence that lettuce has a protective effect on bone health, due to its high content in vitamin K which is required for the synthesis of osteocalcin, a bone protein which helps strengthen bone tissue. This bone protective action is particularly effective in preventing osteoporosisrelated fractures in postmenopausal women and older adults. Lettuce is a good source of calcium and phosphorous, as well, which play a key role in bone structure and health.
