title: Intake of phytochemicals among Japanese, calculated by the new FFF database.
abstract: Effects of phytochemicals on human health are suggested from various animal experiments, but human studies remain insufficient. We have constructed a database of various phytochemicals (polyphenols, carotenoids, and sulphur compounds) (http://www.life-science.jp/fff/) and estimated the amount of intake among Japanese population. The subjects were volunteers (16 males and 63 females, averagely aged 71 and 61, respectively) in Iwate city. Average BMI was 23 in both sexes. Intake of 36 phytochemicals was calculated from one-day dietary records of all intake, by multiplying concentrations of each phytochemical in foods. Phytochemicals with average intake of at least 10 micromole per day were catechin, isoflavones, isothiocyanate, ferulic acid, quercetin, cinnamic acid and chlorogenic acid. Chief component analysis yielded 12 factors (80%).
