Where's the Calcium? Test Your Bone Health IQ
Calcium is crucial to women’s health, especially the long-term health of their bones. We all know we need calcium, but how much and where does it come from? Test your knowledge of the stuff bones are made of!
Question 1 of 10
How many milligrams per day of calcium is recommended for the average adult?
The USDA recommends 1,000 milligrams (mg) of calcium per day for people from 19 to 50 years old.
Question 2 of 10
Pregnant women need to double their calcium intake.
Even though some experts recommend pregnant women increase their calcium intake, it's only to 1,200 mg, a 20 percent increase. And some experts believe if a woman really gets her 1,000 mg, she'll be fine.
Question 3 of 10
Who needs the most calcium?
Teenagers! Kids aged 9 to 18 are still growing their bones and increasing their bone density. They need 1,300 mg calcium a day for this job. And it's a big job. Scientists believe that the denser the bones grown at a young age, the slower the bone decay in old age.
|Pregnant or lactating women|
|Women over 50|
Question 4 of 10
What food source has the most readily available calcium?
While certainly not the only great source of calcium, milk's calcium has high "bio-availability," meaning your body can absorb it easily. It's also a versatile food you can drink straight up or use in a million other ways.
Question 5 of 10
What other substance helps the body absorb calcium?
It helps your bones absorb the calcium, which is why it's often added to foods like milk. Our skin actually makes vitamin D from sunlight!
Question 6 of 10
Where is most of the calcium in our bodies stored?
|Liver and kidneys|
|Brain and spinal cord|
Bones and teeth
Teeth and bones contain about 99 percent of our calcium. But the rest is crucial in muscle contraction, nerve transmission, and blood clotting. Your body will pull calcium from your bones if it doesn't have enough for these other functions (including fetal growth.
|Arteries and veins|
|Hair and nails|
Question 7 of 10
What else besides taking adequate calcium can you do to strengthen your bones?
Exercise, and more specifically, weight-bearing exercise stimulates your bones to add cells and become denser. Non-weight-bearing exercises include swimming, rowing, and riding (horses or bicycles). Those are still great exercise, but should be augmented by weightlifting, dancing, walking, or anything else where you carry your own (if not more) weight.

Question 8 of 10
Which of these is NOT a good source of calcium?
Mushrooms are not a great source of calcium, tasty as they are!
Question 9 of 10
When is orange juice a good source of calcium?
|When it is drunk with soda water|
|When it is fermented|
|When it is heated|
|When it is organic|
When it is fortified
Calcium-fortified orange juice is an easy way to get a high dose of this mineral. We don't recommend drinking fermented orange juice!
Question 10 of 10
Prolonged lack of calcium can lead to what disease?
|Cirrhosis of the liver|
Prolonged lack of calcium most often leads to osteoporosis in adults and elders. Severe lack of calcium or of vitamin D can cause rickets, mostly, but not exclusively, in children.
