Fig. 2. Administration of a diet containing 5% black raspberries (BRBs) caused a significant decrease in the polyp size in the colon of ApcMin/+ mice.
Red circles represent control (ctrl) diet-treated ApcMin/+ mice, blue circles represent 5% BRB diet-treated ApcMin/+ mice, light green circles represent 500 ppm protocatechuic acid (PCA) diet-treated ApcMin/+ mice, dark green circles represent 1,000 ppm PCA diet-treated ApcMin/+ mice (*P < 0.05). Every two groups were compared. There are no differences among the three treatment groups. Bars: mean.
