CDMA (Code Division Multiple Access) and GSM (Global System for Mobiles) are shorthand for the two major radio systems used in cell phones. Both acronyms tend to group together a bunch of technologies run by the same entities. In this story, I'll try to explain who uses which technology and what the real differences are.
Dairy. Dairy products provide nutrients that are critical for bone health, including calcium, potassium and vitamin D. Dairy is also a source of protein. The benefit dairy provides for bones makes consumption especially critical for growing children, whose bone mass is developing.
Since the 1930s, voluntary fortification of milk with vitamin D has been instrumental in the eradication of rickets, a vitamin D deficiency disease that leads to stunted growth, bowed legs and delays in motor development in children.ilk is the No. 1 dietary source of vitamin D, calcium and phosphorus, for Americans 2 years and older. Thus, increasing consumption of vitamin D-fortified dairy foods is a simple strategy to help Americans meet recommended intakes of vitamin D and other important bone-building nutrients.
