How could diet affect joints and bones?

A healthy diet high in fruits, vegetables, whole grains, fish and poultry, nuts, legumes, and low-fat dairy is associated with better bone health.^[1] Getting enough vitamin D, vitamin A, and calcium is particularly important for bone health.^[2] A healthy diet — along with weight loss in people with obesity — is also important for joint health. ^[3] On the other end of the spectrum, being underweight decreases bone density while raising the risk of osteoporosis. Increasing oily fish intake and good sources of vitamin K like leafy greens, Brussels sprouts, and broccoli may also be helpful in slowing osteoarthritis, which is the most prevalent form of arthritis.^[4]
