Why Do Our Bones Need Calcium?
From the day you’re born, your bones are being built with calcium to make them stronger.
Calcium makes bones as strong as steel!
When your body makes new bone tissue, it first lays down a framework of collagen. Then, tiny crystals of calcium from your blood spread throughout the collagen framework. The hard crystals fill in all the nooks and crannies. Calcium and collagen work together to make bones strong and flexible.
Too little calcium makes bones weak.
Your body needs calcium to do lots of things. Calcium helps your muscles work so you can throw a softball. It helps send out nerve impulses. If you touch something hot, for instance, your brain quickly gets and sends the message to say, “Ouch!” and move your hand away. Calcium also helps your body heal from cuts and scrapes.
Every cell in your body needs calcium. Your bones store calcium for your blood and cells. If your body doesn’t get enough calcium, which can be found in some foods and drinks, it takes it from your bones. And that can make your bones weak. From the day you’re born, your bones are built and strengthened with calcium. In fact, when you’re in your 20s, your bones will be their strongest ever.
To make sure your bones are still powerful, even after you’re 30, 40 or even 50 (ancient!), you need to get enough calcium now and keep getting it.
