Results and discussion
Any other information on results incl. tables
The average intake of silicon is 20-50 mg total Si/d
(Pennington, 1991). An estimation of 0.31 mg Si/kg bw/d in
females and 0.53 mg Si/kg bw/d in males made in an American
study, is representative for the intake in the Western
world. While the highest concentrations of total silicon are
found in seafood, eggs and diary products; the main dietary
sources are cereals and beverages.
