Sharon Soroko, MS, researcher with the Division of Epidemiology at the Department of Family and Preventive Medicine at the University of California at San Diego, wrote in a Feb. 4, 1994 study, cowritten with Troy L. Holbrook, Sharon Edelstein, and Elizabeth Barrett-Connor, titled "Lifetime Milk Consumption and Bone Mineral Density in Older Women," published in the American Journal of Public Health, that:

“Osteoporotic low bone mineral density often leads to fractures, costly hospitalization, and prolonged use of health services. Milk accounts for about half of all dietary calcium intake in North America and the importance of calcium in milk for attaining peak bone mass and preventing osteoporosis may relate to the quantity consumed during specific life periods. In this paper, we report the association of lifetime milk consumption with bone mineral density in a community based cohort of older women.

The observed relation between bone mineral density and post adolescent milk consumption is consistent with evidence that a calcium-rich diet during adulthood contributes to peak bone mass and/or helps minimize bone loss.

This study lends further support to the importance of milk in the preservation of bone in women.”
