Document Summary
Bones are 35% organic collagen or vitamin c. the organic structures provide our bodies with strength and durability. The other 65% of our bones are minerals which crystallize and harden our bones. Sadly, there is currently no cure for osteoporosis but they are working on one. Weight barring exercise is the best way to promote bone health and prevent osteoporosis. Calcium and vitamin d also slow down osteoporosis. Bone density peaks at the age of 30, so it is important to build up your bone strength until then so you are healthy after your 30s. Calcium is also important in maintaining a healthy acid- base balance and muscle contractions. Calcium is the most abundant major mineral in the body. 99% of the body s calcium is found in bone. If we do not consume enough calcium, osteoporosis will occur. We need 8. 5-10 mg/day is the blood calcium range we need.
