Abstract
The goal of this study is to investigate the effects of cheese intake on bone metabolism, focusing on 23 residents of an old folks′ home. Group A (n =11) and Group B (n =12) are divided by residence floor, and we conducted a crossover examination. The test diet was food with cheese in it (+200 mg of calcium/day), and the control diet was a normal lunch with calcium supplements (same amount) . Every 4 weeks (4w) they absorbed it, after which we established a 4w period of normal dietary intake. On the first day of each period, we measured bone density (in OSI values) and bone metabolism markers. The periods of the two groups absorbing the test diet were combined into the test diet group, the periods of them absorbing the control diet were combined into the control diet group, and we conducted a comparative study of variability rates before and after the intake periods. We also divided them into groups based on age, BMI, amount of caregivers and serum VD (1α, 25 (OH) 2) concentration, and conducted studies of each. There were no differences in OSI values or BAP variability rates for both the group before and after the intake period, and the group before and after the intake period that included the normal food absorption period. However, the NTx variability rate showed a significant drop. In addition, of those under 85 years of age with high BMI, less than 4 caregivers, and serum VD (1α, 25 (OH) 2) concentrations greater than 37. 5pg/dL, NTx dropped significantly in the test diet group when compared to the control diet group. Some effect of further cheese absorption on bone metabolism was conjectured.
