Colon Cancer is a huge risk and we know there are many contributing factors, including inflammation, hormonal burden, microbial imbalance with excess Fusobaceteria, etc.
Well it appears that Omega-3 on a daily basis can pay off some potential big dividends when it comes to curtailing some of the risk associated with life in a Westernized World. Here is the rest of the story….
Conclusion: Higher intakes of marine-derived n-3 PUFAs are associated with lower risk of adenomatous polyps in women, and the association may be mediated in part through a reduction in the production of prostaglandin E2.
Objective: The objective of this study was to examine the associations of dietary PUFA intake on risk of colorectal adenomatous and hyperplastic polyps.
Design: This was a colonoscopy-based case-control study that included 3166 polyp-free control subjects, 1597 adenomatous polyp cases, and 544 hyperplastic polyp cases. Dietary PUFA intake was calculated from food-frequency questionnaires and tested for association by using unconditional logistic regression. The urinary prostaglandin E2 metabolite, which is a biomarker of prostaglandin E2 production, was measured in 896 participants by using liquid chromatography and tandem mass spectrometry.
Results: n-6 PUFAs were not associated with adenomatous or hyperplastic polyps in either men or women. Marine-derived n-3 PUFAs were associated with reduced risk of colorectal adenomas in women only, with an adjusted OR of 0.67 (95% CI: 0.47, 0.97) for the highest quintile of intake compared with the lowest quintile of intake (P-trend = 0.01). Dietary intake of a-linolenic acid was associated with an increased risk of hyperplastic polyps in men (P-trend = 0.03), which was not seen in women. In women, but not in men, dietary intake of marine-derived n-3 PUFAs was negatively correlated with urinary prostaglandin E2 production (r = -0.18; P = 0.002).
