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 .
Effect of low- and high-calcium dairy-based diets on macronutrient oxidation in humans.
OBJECTIVE Higher calcium and dairy intakes may be associated with lower body weights , but a mechanism in humans has yet to be eluci date d. We compared the effects of a dairy-based high-calcium diet and a low-calcium diet on macronutrient oxidation . RESEARCH METHODS AND PROCEDURES Subjects ( 10 men and nine women ) consumed a low-dairy ( LD , approximately one serving per day , approximately 500 mg Ca(2+)/d ) or high-dairy ( HD , approximately three to four servings per day , approximately 1400 mg Ca(2+)/d ) energy balance diet for 1 week . Each diet condition was performed twice . On the 7th day , subjects were studied in a room calorimeter under one of four study conditions , applied in a r and omized crossover design . Within each diet condition , subjects were studied under conditions of energy balance and acute energy deficit . The deficit ( -600 kcal/d ) was induced only for the 24 hours that subjects resided in the room and was achieved by a combination of caloric restriction and exercise . RESULTS Under energy balance conditions , there was no effect of diet treatment on respiratory quotient or 24-hour macronutrient oxidation . Under energy deficit conditions , 24-hour fat oxidation was significantly increased on the HD diet ( HD with deficit = 136 + /- 13 g/d , LD with deficit = 106 + /- 7 g/d , p = 0.02 ) . DISCUSSION Consumption of a dairy-based high-calcium diet increased 24-hour fat oxidation under conditions of acute energy deficit . We hypothesize that these effects are due to an increased fat oxidation during exercise
