This systematic review highlights the effects of dairy products on muscle mass , muscle strength and body performance in the elderly population in the perspective of Ca , P , vitamin D and protein
The risk of sarcopenia increases with aging .
Malnutrition in the elderly population is an important risk factor for sarcopenia .
Calcium ( Ca ) , phosphate ( P ) , vitamin D and protein are key nutrients for the human body and affect muscle mass and quality .
Dairy products are rich in these nutrients , which implicates that dairy products might be ideal for elderly population .
Associations between dietary nutrient intake and muscle mass and strength in community-dwelling older adults: the Tasmanian Older Adult Cohort Study.
OBJECTIVES To describe associations between dietary nutrient intake and progression of sarcopenia , the age-related loss of muscle mass and strength . DESIGN Prospect i ve cohort study of community-dwelling older adults . SETTING Southern Tasmania , Australia . PARTICIPANTS Seven hundred forty noninstitutionalized older adults ( 50 % female ; mean age 62 ± 7 ) r and omly sample d from electoral rolls .  MEASUREMENTS Dietary nutrient intake  was examined at baseline and follow-up ( 2.6 ± 0.4 years later ) using The Cancer Council Victoria 's Food Frequency Question naire ( FFQ ) . Appendicular lean mass ( aLM ) was assessed using dual X-ray absorptiometry and muscle strength of the knee extensors using a dynamometer . RESULTS Failing to meet the recommended dietary intake for protein was associated with significantly lower aLM at baseline ( -0.81 kg , 95 % confidence interval ( CI ) = -1.54 to -0.08 ) and follow-up ( -0.79 kg , 95%CI = -1.42 to -0.17 ) . Energy-adjusted protein intake was a positive predictor of change in aLM over 2.6 years ( β = 0.10 , P = .003 ) . Energy-adjusted intake of iron ( β = 0.07 , P = .02 ) , magnesium ( β = 0.07 , P=.02 ) , phosphorus ( β = 0.07 , P = .047 ) , and zinc ( β = 0.08 , P = .02 ) were positive predictors of change in aLM , whereas retinol ( β = -0.09 , P = .005 ) was a negative predictor of change in aLM after adjustment for protein intake . No significant associations were observed between nutrient intake and muscle strength . CONCLUSION Protein and several other dietary nutrients are associated with muscle mass and rate of muscle loss ( but not strength ) in older adults , suggesting that multiple dietary components may ameliorate the progression of sarcopenia
