Variables shown are given in mean (sd) units per day. GSL refers to the glucosinolate precursors of sulforaphane and iberin (ie 4-methylsulphinylbutyl and 3-methylsulphinylpropyl glucosinolate) respectively. Similar analysis between GSTM1 positive and null individuals showed no difference in dietary intakes after 6 months within either broccoli-rich or pea-rich intervention.
