Increased intake of omega-3 fatty acids may reduce the risk of colorectal cancer. It has been proposed that anti-inflammatory prostaglandins derived from omega-3 fatty acids may inhibit the cyclooxygenase-2 (Cox-2) enzyme and production of proinflammatory elcosanoids derived from arachidonic acid (omega-6 fatty acids), theoretically linked to cancer formation and cell proliferation. The research investigated the link between the omega-3 and -6 concentrations in the blood of 17B men with colorectal cancer (cases) and 282 age-and smoking-matched controls without cancer. In the study subset not taking aspirin, the subjects with the highest blood concentration of Omega-3’s were associated with a significant 66-percent reduced risk of colorectal cancer, compared with the lowest blood concentration. “Blood levels of long-chain omega-3 fatty acids were associated with decreased risk of colorectal cancer among men not using aspirin,” concluded the researchers.

Omega-3’s Fight Postpartum depression Tucson, AZ—Marine-sourced omega-3 essential fatty acids (N-3 EFAs) combat postpartum depression (PPD), according to a study published online in acta Psychiatrica Scandinavia (www.blackwell-synergy.com). In the eight-week trial, test subjects were randomized to receive 0.5 g/d (n-6), 1.4 g/d (N-3) or 2.8 g/d (n-7) n-3 EFAs (as EPAX omega-3 oil provided by Epax AS, Previously a division of Pronova Biocare AS [www.provona.com]). All groups had reductions in mean scores on Edinburgh Postnatal and Hamilton Rating depression scales (51.5 percent and 48.8 percent, respectively); changes from baseline were significant within each group and when combining groups. The researchers concluded results of the study support further study of n-3 fatty acids as a treatment for PPD. “Omega-3 fatty acids were assessed in a double-blind dose-ranging trial,” said Marlene Freeman, M.D., director of the Women’s Mental Health Program and assistant professor of Psychiatry, Obstetrics & Gynecology, and Nutritional Sciences at the University of Arizona College of Medicine. “A combination of omega-3 EPA and DHA fatty acids provided by EPAX AS was utilized. Among all three doses, patients with postpartum depression improved substantially during the trial. Scores on depression measures decreased by approximately 50 percent and differences were statistically significant.”
