Dec 1, Our bodies continually remove small amounts of calcium from our bones and replace it with new calcium, a bone "remodeling" process. Eating a diet rich in calcium allows the body to deposit calcium in bones so they stay strong. Children and teens who eat calcium-rich foods build up. March 20, -- Calcium alone can't build strong bones and tissues. New research shows calcium needs phosphorus to maximize its bone-strengthening. Jul 1, The objective of the study was to investigate the relationship between dietary calcium intake and bone mineral density (BMD) or bone geometry.

The body only gets the calcium it needs through the food you eat, or from supplements. If you do not get enough calcium in your diet, or if your body does not absorb enough calcium, your bones can get weak or will not grow properly.

Your skeleton bones are a living organ.

Bones are constantly being remodeled with old bone being resorbed and new bone being formed. It takes about 10 years for all the bone in your body to be renewed.

That is why paying attention to bone health is important in adults and not just in growing children. Bone density refers to how much calcium and other minerals are present in a section of your bone.

Bone density is highest between ages 25 and It goes down as you get older. This can result in brittle, fragile bones that can break easily, even without a fall or other injury. The digestive system is normally very bad at absorbing calcium. Vitamin D is the hormone that helps the gut absorb more calcium. Many older adults have common risks that make bone health worse. Calcium intake in the diet milk, cheese, yogurt is low.

Both were published online this week in the medical journal BMJ. A guide to prevention and treatment.

For the first analysis, they looked at more than 70 studies on the effects of dietary calcium and calcium supplements in preventing fractures. They considered both randomized clinical trials and observational studies, and the studies varied widely in terms of numbers of participants, calcium intake, vitamin D intake, and how fractures were reported.

The researchers found that, over all, neither dietary calcium nor calcium supplements were associated with a reduction in fractures. In the second analysis, the team reviewed 59 randomized controlled clinical trials that evaluated calcium intake and bone density.

The Role of Calcium and Vitamin D in Bone Health

Fifteen of those studies involved dietary calcium, and 44 looked at calcium supplements. Over all, getting at least mg of calcium a day from the diet or taking at least 1, mg of supplemental calcium a day increased bone density.

But bone density only increased by about 0. Many people think that osteoporosis only affects women, but men can develop osteoporosis too. The study that started it all?
