Bone is living tissue that is active, so growing a young age and have the ability to repair when damaged or broken. This repair process occurs in the bone surface simultaneously. This special bone cells called osteoclasts that absorbed by bones that have been older, then osteoblasts to replace it with a new one.
After menopause, osteoclasts still absorb and destroy the collagen in bone mineral. However, the osteoblasts become slow work because of lack of estrogen. That's why women at menopause prone to suffer from osteoporosis.
According Fiastuti, vitamin D and calcium, should be satisfied since a young age, because bone density reaches its peak at age 30.
"Bone density decreased with age. At the age of 30 years the speed of the process of bone destruction is greater than the speed of the process of bone loss,"he explained.
