Bone growth begins in the mother’s womb and continues until early adulthood. It is during this growth period that bones develop and increase in mass.
Childhood and adolescence are therefore crucial periods, when we build up strong bones and reduce our risks of fractures and osteoporosis.
Bone is living tissue that is constantly renewing itself. Over time, the body loses its "old bone", which is replaced with "new bone". Growing children and adolescents build up more bone tissue than lose it.
Up to 90% of maximum bone mass forms before age 18 in girls and 20 in boys. For this reason, we must invest in our bones’ health prior to adulthood, by providing our bodies with the right intake of calcium and vitamin D.
For healthy bones, children must also get enough exercise. They should choose sports where the feet and legs support the weight of the body, including dance, running, ball sports, skating, etc.
The perfect combination for healthy bones? Calcium, vitamin D and an active life!
