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 .
Sexually dimorphic patterns of nutritional intake and eating behaviors in community-dwelling older adults with normal and slow gait speed
Objectives Assess sex-specific nutritional intake and dietary habits of independently living older adults with normal and slow gait speeds . Design New Mexico Aging Process Study , cross-sectional , secondary data analysis . Setting Albuquerque , New Mexico USA . Participants Three-hundred fifteen adults 60 years and older ( 194 women and 121 men ) . Measurements  Gait speed test , 3-day diet records , Mini-Mental State Examination , and body mass index . Results Slow gait speed was associated with lower total calories ( −154 kcal/day ) and zinc ( 1mg/day ) ( .05 < p < .1 ) . Slower men consumed less protein ( −4.1g/day ) ,  calcium  ( −140 mg ) , fiber  ( -2.8g/day ) and iron  ( −2.5mg/day ) ( p<.05 ) . Slower women consumed less , protein ( −5.5g/day ) , carbohydrate ( −19.1g/day ) , fiber ( −2.7gm/day ) , vitamin C ( −18.4mg/day ) and higher fat intake ( p=0.03 ) . Slower women snacked less , had trouble chewing/biting , and lived alone ( p=.04 ) . Slower men were less likely to snack . Conclusions We found sex-specific nutritional differences associated with gait speed . Those presenting with slow gait speed may need encouragement to increase meat and whole grain breads/cereal . Those with trouble eating should be advised on adapting diet to maintain adequate nutrition and encouraged on regular snacking to achieve higher nutrient intake . Prospect i ve and r and omized controlled studies are needed to confirm these findings and provide further evidence for putting these suggestions into practice
