If you went through any periods of hyperthyroidism, or are a thyroid cancer survivor, you are at greater risk than the average member of the public of loss of bone density. Though public awareness of calcium's role in preventing osteoporosis has increased in recent years, many adults still consume only half of the recommended daily intake of 1,000 to 1,200 mg of calcium, according to the National Osteoporosis Foundation. Getting sufficient calcium is particularly important for thyroid patients.

"When you don't get enough calcium from your diet," says Lynn Moss, M.S., R.D., "the body will take the calcium it needs from your bones, eventually leading to bone porosity or osteoporosis." Moss, nutrition advisor for Optimize Hi-Calcium and Hi-Fiber beverages, concludes, "We're finding that not just one but a number of lifestyle habits may lead to calcium deficiency."

To arm consumers with information on bone loss prevention, Moss recommends people know the following "secret stealers" of calcium.

1. Lack of vitamin D. A recent study from Harvard Medical School found that 30 to 40 percent of people in the United States might be vitamin D deficient. Vitamin D is necessary for the intestinal absorption of calcium.
2. Too much salt. A high-sodium diet increases the loss of calcium and other minerals through the kidneys into the urine. Every two extra grams of dietary sodium decreases the amount of calcium absorbed by 30 to 40 mg.
3. Some prescription drugs. A number of prescription medications have been shown to interfere with calcium absorption, including diuretics, corticosteroids, anticonvulsants, immuno-suppressive medications, non-steroidal anti-inflammatory drugs, asthma medications with steroids, and a number of antibiotics. Ask your doctor if your medication interferes with calcium absorption.
4. Smoking/excessive drinking. A number of studies have shown smoking accelerates bone loss and contributes to less efficient calcium absorption. In addition, drinking alcohol on a regular basis can break down bone mass in both men and women. Individuals who consume alcohol regularly (2 to 3 oz/day) are more likely to have poor nutrition habits and are at a greater risk for bone loss and fractures due to falls.
5. Lack of exercise. Individuals who get little or no exercise—especially weight-bearing exercise, such as walking and weightlifting—and have inadequate calcium intake, are at risk for calcium depletion from the bones.
