To examine the potential role of habitual isoflavones intakes in bone status of men, a total of 463 Korean healthy adult males aged 20–26 were observed for their diet intake and calcaneus bone density using 3 day 24‐hr recall method and quantitative ultrasound, respectively. Critical markers reflecting bone metabolism such as blood total alkaline phosphatase activity (ALP) and N‐mid osteocalcin (OC) concentrations were also analyzed. For quantitative data on the intake levels of isoflavones, previous study monitoring phytoestrogens in 220 Korean leguminous foodstuffs was employed and the median value for each food was adopted. Isoflavones intake of the subjects was estimated as 14.80 mg/day, which constituted 7.49 mg daidzein, 6.49 mg genistein, 0.82 mg glycetin, 0.00 mg formononetin, and 0.00 mg biochanin A. The intake level turned out to be lower than the average daily isoflavones intake of Korean (23.0 mg, Surh et al, 2006) and much lower than the amount reputed to prevent osteoporosis (40–50 mg/day, Anderson & Garner, 1997), which should lead to no appreciable correlations among isoflavones intakes, bone mineral density of calcaneus, and blood bone metabolism markers measured in the young Korean adult males.
