g Osteoporosis and related low bone mass affect many adults in North America, especially older women. One-third of all women experience fractures because of this disease, amounting to about 2 million bone fractures per year. Osteoporosis is a disease you can do something about. Some risk factors cannot be changed, but others, such as poor calcium intake, can. Is this true for you

That is true.

Explanation:

Osteoporosis promotes bone loss and people who suffer from this disease are more prone to fractures, especially in dangerous places like the hips and spine. Although some factors that promote this disease cannot be avoided, such as the genetic factor, osteoporosis can be prevented and even avoided with adequate intake of calcium, which is one of the main elements of bone mass. However, it is incorrect to say that only calcium intake is sufficient to prevent osteoporosis, as it is necessary to combine food with constant physical activity, which is capable of strengthening and promoting density to the bones.
