Curcumin and colorectal cancer:
Curcumin and colorectal cancer prevention: A 15-week study conducted on mice found that curcumin supplementation may have chemopreventive properties against colorectal cancer. Curmurin at 0.1%, 0.2% or 0.5% in the diet of mice was examined. Compared with untreated mice, curcumin at a dietary amount of 0.2%-0.5%, reduced benign tumors by 39% and 40%, respectively. Dietary curcumin also partially restored suppressed hematocrit values (a measure of the percentage of red blood cells in whole blood). Traces of curcumin were detected in the plasma and tissues of the small intestine (between 39 and 240 nmol/g) for 2-8 hours after dosing. The researchers concluded, curcumin may have a benefical effect against cancer and recommend a daily dose of 1.6 grams of curcumin for possible benefits to be seen in humans. (5)
