Fig. 1. Administration of a diet containing 5% black raspberries (BRBs), 500 ppm protocatechuic acid (PCA), or 1,000 ppm PCA caused a significant decrease in the number and the size of polyps in the small intestine 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 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.
