Oh, Sorry!
Calcium is an essential mineral and plays roles in:
Bone health
Blood clotting
Nerve cell "communication"
Muscle contraction
All of these
All of these
No bones about it, calcium is necessary for your body, not just for bones.*
What are natural food sources for calcium?
Milk, yogurt & cheese
Kale and bok choy
Soy, nuts
All of the above
All of the above
And for Vitamin D, add canned fish (sardines and tuna packed in oil) to your shopping list, too.

Tip: Choose low-fat and no-fat sources of calcium-rich food; their calcium content/benefit is the same and you won't be adding as many fat calories.
How many milligrams of calcium do adults need daily throughout life?
The recommended amount of calcium depends on age, life stage and gender. The Dietary Reference Intake guide (DRI) says adults should take between 1,000-1,200mg daily and children/teens aged 9-18 should have 1,300 mg per day.

Tip: To gauge dietary intake: 1 serving of dairy product yields about 300mg calcium. Supplements like Caltrate® can help you get your daily recommended levels.
Which vitamin helps your body absorb calcium?
Vitamin D, also known as the "sunshine vitamin" because the body manufactures it after being exposed to sunlight. Vitamin D is both a vitamin and a hormone, and it's the only vitamin that the body can make on its own, thanks to the sun. People aged 50 - 70 should get 400 IU (international units) of vitamin D daily; If you're over 70 years of age, increase that to 600 IU per day.
Your body will withdraw calcium from your bone "bank" if you don't meet your daily requirements.
Meet the Bank of Calcium's "Most Wanted" list: Your body. When it doesn't get enough calcium, your body takes it from your bone "bank." If more calcium is withdrawn than you deposit daily, you can become calcium deficient.
Bones are living tissues that always break down and rebuild. After what age does the buildup start to slow and bone mass become smaller?
30 years of age
60 years of age
80 years of age
30 years of age
Until we're 30, we build more bone than we lose. After 30, bones break down more readily than they build up, resulting in less bone mass as we age. An outer shell of dense bone surrounds the sponge-like inner bone. When bones are weakened by conditions such as osteoporosis, the "holes" in the sponge expand and weaken the internal structure.
How can we help maintain strong bones?
Avoid smoking cigarettes & drinking alcohol
Get enough calcium & vitamin D
Exercise minimum 30 minutes/day
All of the above
All of the above
Try to stop smoking or drinking excessively, and get more active. Exercise and eat more calcium-rich or calcium-fortified food and beverages. All of these contribute to overall bone health.
What percentage of people suffer osteoporosis-related fractures within their lifetime?
100% females, 10% men over 50 yrs. old
30% females over 40, 25% men over 30
50% females, 25% men over 50 yrs. old
50% females, 25% men over 50 yrs. old
Much of this disparity between men and women is due to hormones: Women lose estrogen as they age, which goes hand in hand with bone loss. Source: American Journal of Epidemiology.
When do hormones contribute to female bone loss?
During menopause
Disrupted menstrual cycles
5-10 years after menopause
All of these
All of these
Up to 20% bone mass can be lost within the first 5-10 years after menopause. Women who reach menopause early, have absent or infrequent menstrual periods due to eating disorders or extreme physical activity that prolongs weight loss, are at risk for low bone density.
Which physical activity helps strengthen bones?
All of these
All of these
Strength-training and weight-bearing exercises that put pressure on bones like jumping, running, and lifting weights, are another great way to get your daily intake of calcium. The Journal of Pediatrics recommends that children get at least 60 minutes of exercise each day. The American Heart Association recommends that adults 18-65 years old should get at least 30 minutes of exercise five days a week. Walking, biking, swimming, skating and dancing are all fun ways to stay active and improve your balance so you avoid fractures from falling.
