Question on front of packet
Calcium helps to keep bones strong but just drinking milk doesn’t mean that you won’t get osteoporosis. You may be genetically inclined to get it even though you drink milk every day. There are also many other things that contribute to getting osteoporosis, like not eating enough calcium, doing steroids causes bones to become weak and look like sponges when looking at it under a microscope. Scenarios A,B, and C help to explain that it’s not just the calcium that can cause osteoporosis
Scenario A:
1. The skeleton is a metabolically active organ that undergoes continuous remodeling throughout life. Bone remodeling involves the removal

Scenario B:
1. It is essential for muscle contraction, but also essential to the structure and health of bones. Bones are continually remodeling and reforming and calcium is a vital part of this process. Without calcium bones can become very thin. Bones are structured to provide strength, protection, and movement. In addition the structure allows the bones to serve as a reservoir for several minerals including calcium because calcium can quickly move between the bone and the blood.
2. Foods high in calcium consist of spinach, kale, okra, collards, soybeans, white beans, some fish (such as sardines, salmon, perch, and rainbow trout), some orange juice, oatmeal and breakfast cereal.
3. Vitamin D promotes calcium absorption in the gut and maintains serum calcium and phosphate concentrations to enable normal mineralization of bone and to prevent hypocalcemia tetany. It is also needed for bone growth and bone remodeling by osteoblasts and osteoclasts. Without significant vitamin D bones can become brittle, thin, or misshapen. Vitamin D sufficiency rickets in children and osteomalacia in adults. Together with calcium and vitamin D also helps protect older adults form osteoporosis.
4. Men and women have different allowances such as men : 19-50 1,000mg 51-71 1,000mg 71- older 1,200mg
19-50 1,000mg 51-older 1,200mg
And there are also supplements Calcium carbonate (40% of elemental calcium) Calcium citrate (21% elemental
