  • a LS-mean ± SE, adjusted for sex, GSTM1 genotype, feeding period, and sampling day.

  • b The difference of LS-means between the vegetable diets and the basal diet.

  • c One GSTM1-null male and one GSTM1-null female did not complete the basal diet; one GSTM1+ male did not complete the brassica and allium diets; and one GSTM1-null male did not complete the apiaceous diet.

  • d Significant comparison between vegetable diet and basal diet (P < 0.05).
