The menopausal transition is characterised by rapid bone loss. The objective of the study was to ascertain which dietary factors influence skeletal loss around the time of the menopause. In the study, the bone mineral density was measured at the start of the study and five years later in 891 women initially aged 45-55.
Regarding fat intake, the study found:
(a) A higher intake of saturated fat was correlated with a protective effect from bone mineral loss.
(b) A higher intake of polyunsaturated fat was correlated with lower bone mineral density
