Mean values with their SEM for seven rats per group, six rats per group for blackberry +HEAL19 (caecal pool), for blackberry (proximal and distal colon), and for blackcurrant +HEAL19 (proximal colon).
1Groups fed blackcurrant were significantly higher than those fed blackberry and raspberry.
2Groups fed blackcurrant were significantly higher than those fed blackberry.
3Groups fed blackcurrant and raspberry were significantly higher than those fed blackberry.
4Groups fed raspberry were significantly higher than those fed blackberry.
