4. Expose your naked, un-sunscreened skin to sunlight 10 minutes a day. In spring and summer, ultraviolet rays are strong enough to activate vitamin D in the skin. A few foods contain vitamin D — cod liver oil, oily fish, shiitake mushrooms, eggs and fortified milk, soy milk and orange juice — but our primary source is sunshine. This vitamin stimulates calcium absorption from the intestinal tract. Inadequate levels are linked with osteoporosis and bone fractures. Most North Americans don’t maintain healthy blood levels from sunlight and diet. Women over 65 are often advised to take 800 IU a day. Lately, vitamin D researchers have been calling for at least 1000 IU a day — several times the current guidelines for 200 to 600 IU.

5. Watch out for the bone robbers:
- Soda, particularly cola drinks, contains phosphates (and too much lowers blood levels of calcium) and too often replaces bone-friendly beverages such as milk. Teenage girls who drink a lot of cola beverages are at increased risk of bone fractures.
- Cigarette smoke and alcohol (more than two drinks a day) are both linked to osteoporosis and fractures.
- Estrogen loss. No matter your age, if you’ve stopped having your periods (for reasons other than pregnancy) talk to your doctor about how best to protect your bones.
- Chronic stress. The stress response activates the hormone cortisol, which causes bone loss. Taking cortisone and related drugs also reduces bone mass. Do your best to keep your mood mellow.
6. Maximize your bone mass while you’re young. The earlier you begin to acquire the healthy habits described above, the better. The more bone you deposit by the time you enter your fourth decade, the lower your chances of going broke. If that opportunity has passed, you can work to slow the rate of bone loss (and to educate your daughters, younger sisters and friends).
7. Get tested for osteoporosis. This condition causes no symptoms until you feel the pain of a fractured bone. Dual-energy x-ray absorptiometry (DEXA) offers a safe, painless and reliable measurement of bone mineral density. Doctors often recommend a baseline DEXA scan as a woman begins menopause, then periodic scans to monitor bone loss.
