Please explain in detail about the following topic: Osteoporosis Coefficient (Rheumatoid Bone Disease)

The given explanation should be useful and easy to understand for patients with no scientific background. Use of medical terms is still encouraged. The explanation should include information on what patients can do to improve it. The explanation can be improved upon the below explanation:

It is a phenomenon of bone reduction of the whole body. It is mainly showed that the content of bone matrix is significantly reduced, while the components of minerals (mainly containing calcium and phosphorus) in the bone are basically normal. In other words, in osteoporosis, the content of protein and other organic substances and water in the bone are decreased, and the content of calcium, phosphorus and other minerals are at the normal level. The bone matrix plays the role of support and connection between calcium, phosphorus and other minerals. Thus, if the bone matrix is reduced, the gaps among the minerals are increased, being expressed as osteoporosis. With the progress of osteoporosis, calcium, phosphorus and other minerals in the bone will also be constantly lost and reduced, and therefore the bone matrix and minerals of the bone are decreased. Osteoporosis in old age is actually a consequence of long-term calcium deficiency. In general, bone calcium of male after the age of 32 and female after the age of 28 begins to lose. With the increasing age, the loss rate will also be accelerated. 50% of bone calcium has been lost at 60 years old. Thus, at present, it's time to prevent fracture and prevent osteoporosis and supplement calcium. Therefore, diet nutrition is very much related to the occurrence of osteoporosis. Children and adolescents under 18 years old should take in 1200 mg of calcium each day, and adults should take in 800 mg of calcium each day. At the same time, it is need to take in many vitamins D to help the body more easily and more effectively absorb calcium.
