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 Apc^Min/+ mice. Red circles represent control (ctrl) diet-treated Apc^Min/+ mice, blue circles represent 5% BRB diet-treated Apc^Min/+ mice, light green circles represent 500 ppm PCA diet-treated Apc^Min/+ mice, dark green circles represent 1,000 ppm PCA diet-treated Apc^Min/+ mice (*P < 0.05). Every two groups were compared. There are no differences among the three treatment groups. Bars: mean.
