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 .
Nutrient-rich dairy proteins improve appendicular skeletal muscle mass and physical performance, and attenuate the loss of muscle strength in older men and women subjects: a single-blind randomized clinical trial
Background At present , it is unknown whether the use of nutrient-rich dairy proteins improves the markers of sarcopenia syndrome . Therefore , our proposal was to investigate whether adding 210 g of ricotta cheese daily would improve skeletal muscle mass , h and grip strength , and physical performance in non-sarcopenic older subjects . Subjects and methods This was a single-blind r and omized clinical trial that included two homogeneous , r and omized groups of men and women over 60 years of age . Participants in the intervention group were asked to consume their habitual diet but add 210 g of ricotta cheese ( IG/HD + RCH ) , while the control group was instructed to consume only their habitual diet ( CG/HD ) . Basal and 12-week follow-up measurements included appendicular skeletal muscle mass ( ASMM ) by dual-energy X-ray absorptiometry , h and grip strength by a h and held dynamometer , and physical performance using the short physical performance battery ( SPPB ) and the stair-climb power test ( SCPT ) . The main outcomes were relative changes in ASMM , strength , SPPB , and SCPT . Results ASMM increased in the IG/HD + RCH ( 0.6±3.5 kg ) , but decreased in the CG/HD ( −1.0±2.6 ) . The relative change between groups was statistically significant ( P=0.009 ) . The relative change in strength in both groups was negative , but the loss of muscle strength was more pronounced in CG/HD , though in this regard statistical analysis found only a tendency ( P=0.07 ) . The relative change in the balance-test scores was positive for the IG/HD + RCH , while in the CG/HD it was negative , as those individuals had poorer balance . In this case , the relative change between groups did reach statistical significance . Conclusion The addition of 210 g of ricotta cheese improves ASMM and balance-test scores , while attenuating the loss of muscle strength . These results suggest that adding ricotta cheese to the habitual diet is a promising dietetic strategy that may improve the markers of sarcopenia in subjects without a pronounced loss of ASMM or sarcopenia
