e a potential anti-absorbing agent for calcium. However Heaney's own experimentation has shown that there may be less variation than expected with low levels of phosphorus intake on overall human calcium balance. The converse, however, is not true: High levels of intake of calcium do successfully block the absorption of phosphorus. Hence, it seemed useful to examine more closely the possibility of a counterpart interference.
There are a number of other factors to consider when examining the connection between calcium, Vitamin D and bone health, including the effects of protein consumption and calcium absorption rates, as Marsh (1988) suggests.
The complexity of maintaining bone health is even more difficult for some people than others, and certain segments of the population are at greater risk than are others. Women over the age of 60, for example, tend to have poor bone health in part because they receive a great deal of their calcium in the form of calcium supplements. These supplements contain calcium carbonate, a form of calcium that may actually b
