Calcium is an important mineral in homeostasis in all vertebrate animals. It is the most abundant mineral in the body, and is the major component of bones and teeth. In addition, calcium is involved in various vital physiologic processes, including blood coagulation, muscle contraction, membrane permeability, nerve conduction, enzyme activity, and hormone release. If calcium levels in the blood drop below normal, calcium will be taken from bone and put into the blood in order to maintain blood calcium levels. Therefore, it is important to consume enough calcium to maintain adequate blood and bone calcium levels. The most abundant mineral in human body is calcium, and 99% of its in teeth and bone. Consuming mineral enriched food is one of the most nutritious and essential in food consumption for human. Recently, many studies have presented that food habits of Mongolian people have modified and diverse dramatically and the minerals, including calcium, which are essential for body, are quite low level in their food consumption.
