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 .
Association of protein intake with the change of lean mass among elderly women: The Osteoporosis Risk Factor and Prevention – Fracture Prevention Study (OSTPRE-FPS)
Low protein intake can lead to declined lean mass ( LM ) in elderly . We examined the associations of total protein ( TP ) , animal protein ( AP ) and plant protein ( PP ) intakes with LM . The association of TP intake with LM change was further evaluated according to weight change status . This cross-sectional and prospect i ve cohort study included 554 women aged 68 ( sd 1·9 ) years from the Osteoporosis Risk Factor and Prevention – Fracture Prevention Study ( OSTPRE-FPS ) . The intervention group ( n 270 ) received daily cholecalciferol ( 800 IU ; 20 μg ) and Ca ( 1000 mg ) for 3 years while the control group received neither supplementation nor placebo ( n 282 ) . Participants filled out a question naire on lifestyle factors and a 3-d food record in 2002 and underwent dual-energy X-ray absorptiometry for body composition measurements at baseline and 3 years . Multiple linear regressions evaluated the association between protein intake and LM , adjusting for relevant covariates . At the baseline TP and AP intakes were positively associated with LM and trunk LM , TP was associated also with appendicular LM ( aLM ) . Follow-up results showed that in the total population and the intervention group  , higher TP and AP were associated with increased LM and aLM ( P ≤ 0·050 ) . No such associations were observed in the control  group . PP intake was also associated with aLM change in the total population . Overall , the associations were independent of fat mass . Further , among weight maintainers , TP intake was positively associated with LM , aLM and trunk LM changes ( P ≤ 0·020 ) . In conclusion , dietary  TP , especially AP , intake may be a modifiable risk factor for sarcopenia by preserving LM in the elderly
