In conclusion , the role of dairy products for BMC or BMD has been sufficiently established in Chinese and Caucasian girls and women .
In Caucasian women , drinking milk also reduces fracture risk .
The relevance of dairy produce for the diminishment of osteoporotic risk is still a matter of scientific debate due to the outcome of a few single observational studies .
Identification of a dietary pattern prospectively associated with bone mass in Australian young adults.
BACKGROUND Relatively little is known about the relations between dietary patterns and bone health in adolescence , which is a period of substantial bone mass accrual . OBJECTIVES We derived dietary patterns that were hypothesized to be related to bone health on the basis of their protein , calcium , and potassium contents and investigated their prospect i ve associations with bone mineral density ( BMD ) , bone area , and bone mineral content ( BMC ) in a cohort of young adults . DESIGN The study included 1024 young adults born to mothers who were participating in the Western Australian Pregnancy Cohort ( Raine ) Study .  Dietary information was obtained from food-frequency question naires at 14 and 17 y of age . Dietary patterns were characterized according to protein , calcium , and potassium intakes with the use of reduced-rank regression . BMD , bone area , and BMC were estimated with the use of a total body dual-energy X-ray absorptiometry scan at 20 y of age . RESULTS We identified 2 major dietary patterns . The first pattern was positively correlated with intakes of protein , calcium , and potassium and had high factor loadings for low-fat dairy products , whole grains , and vegetables . The second pattern was positively correlated with protein intake but negatively correlated with intakes of calcium and potassium and had high factor loadings for meat , poultry , fish , and eggs . After adjustment for anthropometric , sociodemographic , and lifestyle factors , a higher z score for the first pattern at 14 y of age was positively associated with BMD and BMC at 20 y of age [ differences : 8.6 mg/cm(2 ) ( 95 % CI : 3.0 , 14.1 mg/cm(2 ) ) and 21.9 g ( 95 % CI : 6.5 , 37.3 g ) , respectively , per SD increase in z score ] . The z score for this same pattern at 17 y of age was not associated with bone outcomes at 20 y of age . The second pattern at 14 or 17 y of age was not associated with BMD , BMC , or bone area . CONCLUSIONS A dietary pattern characterized by high intakes of protein , calcium , and potassium in midadolescence was associated with higher BMD and BMC at 20 y of age . Our results indicate that high consumption of low-fat dairy products , whole grains , and vegetables in adolescence are associated with beneficial effects on bone development
In conclusion , the role of dairy products for BMC or BMD has been sufficiently established in Chinese and Caucasian girls and women .
In Caucasian women , drinking milk also reduces fracture risk .
The relevance of dairy produce for the diminishment of osteoporotic risk is still a matter of scientific debate due to the outcome of a few single observational studies .
