Intake of calcium and vitamin D at the recommended levels, in the context of a healthy diet and coupled with exercise, contribute to healthy skeletal development in the first two decades of life and then to the maintenance of bone.
Attaining maximum bone mass in adolescence through adequate calcium and vitamin D intake coupled with regular weight-bearing exercise is known to protect against osteoporosis, a disease often acquired in the older adult years in which the density and quality of bone are reduced. Osteoporosis is a major public health threat for an estimated 44 million Americans, and it causes 1.5 million fractures each year, over 300,000 of which occur at the hip. Osteoporosis is under-treated and underrecognized, with differences in underserved and minority populations.
Public health & education application
Studies, specifically on milk and milk products such as yogurt and cheese, showed a positive relationship between the intake of such products and bone mineral content and density in one or more skeletal sites.
This scientific base has contributed to the inclusion of milk and other dairy products in federal dietary guidance and emphasizing these items in federal nutrition programs, including the Special Supplemental Program for Women, Infants and Children (WIC).
Scientific discoveries in this area also have spawned the development of new food products and have led to a greater understanding of the prevalence of lactose intolerance in certain populations. Significant amounts of calcium now can be acquired from fortified breads, cereals, fruit juices, soy beverages, and commercial mineral water. These foods provide a suitable alternative for people who are lactose-intolerant and for vegans.

Some vegetables as the lettuce, cabbage and spinach provide significant amounts of calcium. We can´t forget the beneficial sun effects in the calcium absortion.
