A diet supplemented with freeze-dried black raspberries (BRBs) has been demonstrated to modulate various biochemical and physiological pathways in both colorectal cancer (CRC) patients and ApcMin/+ mice, which are utilized to model CRC. These changes have been previously shown to exert beneficial chemopreventive effects against CRC, with outcomes such as reduction of adenoma development and inflammation. This study aimed to assess whether these effects manifest in a meaningful change in survival rates by comparing these rates between ApcMin/+ mice administered a 5% BRB-supplemented diet or a control AIN-76A diet. Percent survival over days elapsed was assessed in order to determine a median length of survival for each group of mice. Significant increases in survival rates with consumption of the BRB diet versus the control diet were demonstrated in both male and female mouse study groups. Male and female control groups were also compared in order to reduce confounding due to the sex of the mice; the difference in survival rates between male and female mice was not significant (p = 0.07, *p < 0.05), as male mice lived for a median of 143 days and females for 194 days. The results of this study suggest that administration of a BRB-supplemented diet may potentially prolong the lifespan and increase survival rates of colorectal cancer patients.
