Good bone health throughout the lifespan

Good bone health throughout the lifespan

Bone is alive and constantly changing throughout life. Old, worn out bone is broken down by cells called osteoclasts and replaced by bone building cells called osteoblasts, a process of renewal called bone turnover. Maintaining bone health is essential and this should start from early childhood and adolescent years as most of the bone development takes place during these years.

As we get older our bones start to lose strength and density as the work of the bone demolition cells start to slowly overtake the work of the bone construction cells. The older we get, the greater our risk of breaking a bone. Fragility fractures become more common as the density of bone decreases and bones become generally less strong and more fragile. Protecting your bone health is easier than you think. From childhood and adolescence, when bone growth occurs, to adulthood, when low bone mass and osteoporosis may become a concern, to pregnancy and lactation, when bone health is important for both mother and baby, a diet that includes adequate amounts of calcium and vitamin D, physical activity and lifestyle choices play a central role in keeping bones healthy. It's best to start controlling these factors to build healthy bones as a child and adolescent, but there are also steps an adult can take to protect their existing bone health.
