Calcium blocks the absorption of heavy metals, and it has been found, for example, that a low-calcium diet increases the susceptibility of rats to lead poisoning. Adequate calcium in the diet of humans under the age of 30 is thought to retard the development of osteoporosis through an increase in bone mass.
