Fish Intake and Colorectal Cancer

In a very large, long-term study of colorectal cancer, it was found
that intake of fish oil and dietary fish dramatically decreases the risk
of colorectal cancer. In this study, which monitored over 21,000
subjects for 22 years, it was found that those who consumed fish 5
times/week had a 40% reduction in colorectal cancer. In classic “let’s
understate the benefits of natural therapies” fashion, the authors
concluded, “Our results … suggest that intakes of fish and long-chain
omega-3 fatty acids from fish may decrease the risk for colorectal
cancer.” If a drug had this kind of protective effect, we’d all be
forced to take it as a matter of national security.
