Which dietary measure is NOT effective in reducing the risk of osteoporosis?

The option indicating that drinking organic juice is not effective in reducing the risk of osteoporosis is correct because organic juice does not significantly provide the key nutrients needed to support bone health. Osteoporosis prevention relies heavily on adequate intake of calcium and vitamin D, which are essential for bone development and maintenance. While juices can be part of a healthy diet, they typically lack sufficient amounts of these crucial nutrients.

In contrast, eating low-fat dairy foods is beneficial, as they are rich sources of calcium and often fortified with vitamin D, both of which are vital for maintaining bone density. Performing weight-bearing exercises is also a well-recognized method to promote bone strength, as such activities help stimulate bone formation and slow down bone loss. Additionally, vitamin D supplementation can significantly enhance calcium absorption in the gut, thereby supporting bone health and reducing osteoporosis risk.
