Abstract

Accumulated data suggests a positive effect of silicon on bone health however limited research exists on the silicon content of foods To further the understanding of the relationship between dietary silicon intake and bone health a food composition database of commonly consumed foods in Korea is required For quantitative data on the intake levels of silicon we analyzed the silicon content of 365 food items commonly consumed in Korea using inductively coupled plasma—atomic emission spectrometry following microwaveassisted digestion To investigate the dietary silicon intake status and to examine the potential role of dietary silicon intake in the bone status of men a total of 400 healthy Korean adult males aged 19–25 were observed for their diet intake and calcaneus bone density using the 24h recall method and quantitative ultrasound respectively Clinical markers reflecting bone metabolism such as serum total alkaline phosphatase Nmid osteocalcin and type 1 collagen Cterminal telopeptide concentrations were also analyzed Silicon intake of the subjects was estimated as 375 ± 222 mg/day Major food sources of dietary silicon in the Korean male were cereal and cereal products 256  of total silicon intake vegetables 227 beverages and liquors 212 and milk and milk products 70  Silicon intake correlated positively with age weight energy intake protein intake calcium intake and alcohol intake After adjusted for age weight energy intake protein intake calcium intake alcohol intake smoking cigarettes and regular exercise status daily total silicon intake had no correlation with calcaneus bone density and the bone metabolism markers but silicon intake from vegetables had a positive correlation with serum total alkaline phosphatase activity a bone formation maker These findings show the possible positive relationship between dietary silicon intake from vegetables and the bone formation of young adult males Further investigation in a larger Korean population and correcting for additional nutritional confounders is required to confirm these findings
