Why is Calcium So Important in Childhood and Adolescence?
Building a solid foundation for strong bones starts in our early years. That's why having a high calcium intake is so essential for helping bone density and overall health. In fact, according to the National Osteoporosis Foundation, peak bone mass is usually reached between the late teens and early 20’s. 2 This means that your genetic predisposition for laying down bone occurs early in life. In children, a calcium and vitamin D deficiency may lead to rickets —- a failure of bone to mineralize or a softening of bone mass. Low dietary intake of calcium can lead to bone deformities and growth slowing. The message is clear: take measures to help support bone health with an adequate intake of calcium and vitamin D during childhood and adolescence. According to the National Osteoporosis Foundation, osteoporosis is a condition in which the bones become weak and may break from a minor fall. This can occur when you lose too much bone, make too little bone -- or both, and is common in older individuals. 3 Adequate calcium and vitamin D as part of a healthful diet, along with physical activity, may reduce the risk of osteoporosis later in life.

Did You Know?
Certain nutrients and medications may increase your need for calcium because they either lower the absorption of calcium in the gut or cause more calcium to be excreted in the urine . These include: corticosteroids (example: prednisone), excess sodium in the diet, phosphoric acid such as found in dark cola sodas, excess alcohol, and oxalates (see Are anti-nutrients harmful? ).
How does the body work to keep calcium levels in the blood?
If calcium levels drop too low in the blood, parathyroid hormone (PTH) will signal the bones to release calcium into the bloodstream. This hormone may also activate vitamin D to improve the absorption of calcium in the intestines. At the same time, PTH signals the kidneys to release less calcium in the urine. When the body has enough calcium, a different hormone called calcitonin works to do the opposite: it lowers calcium levels in the blood by stopping the release of calcium from bones and signaling the kidneys to rid more of it in the urine.
What are some examples of anti-nutrients?
A downside to some plant foods is that they contain naturally occurring plant substances, sometimes referred to as “ anti-nutrients .” Examples of anti-nutrients are oxalates and phytates that bind to calcium and decrease its bioavailablity. Spinach contains the most calcium of all the leafy greens at 260 mg of calcium per 1 cup cooked, but it is also high in oxalates, lowering the bioavailability so that only 5% or about 13 mg of calcium can be used by the body. The takeaway message is not to avoid spinach, which contains other valuable nutrients, but not to rely on spinach as a significant source of calcium since most of it will not be absorbed by the body. You can also schedule your meals so that you do not eat “calcium-binding” foods like spinach at the same meal as calcium-rich foods or with calcium supplements.
How long does it take for a trial to show colorectal cancer?

How much calcium is in bok choy?
For example, bok choy contains about 160 mg of calcium per 1 cup cooked but has a higher bioavailability of 50%, so about 80 mg is absorbed. Therefore, eating 1 cup of cooked bok choy has almost as much bioavailable calcium as 1 cup of milk.
Which has more bioavailability, dairy or plant foods?
For example, dairy foods have a bioavailablity of about 30% absorption so if a food label on milk lists 300 mg of calcium per cup, about 100 mg will be absorbed and used by the body. Plant foods like leafy greens contain less calcium overall but have a higher bioavailability than dairy.
