564 elderly women aged 80-92 (mean 84.7) years were observed over a 10 years period. The results show that consumption of more than 2.2 portions of dairy produce per day is accompanied by a larger bone mass around the tibia (+5.7%) and a larger total bone mass volume (+6.2%), by comparison with less than 1.5 portions daily.
Major consumers of dairy products also have a larger appendicular bone mass (+7.1%) and a larger skeletal muscular mass (+3.3%). These associations would probably rely upon the supply of protein and calcium from the dairy produce. However, the results of the study do not show any distinction between the dairy products.
