^*Changes in frequencies of food consumption were significantly different from their comparator values (P<0·05).

^†Changes in daily frequency of consumption of intervention group 1 and intervention group 2 from baseline (week 0) were compared with changes from baseline in the control group (week 0) by the non-parametric, two-sample Wilcoxon rank-sum test. Control values from week 8 and week 16 were compared with those at baseline.
