Thing: When Fish Oil Starts Clogging Your Arteries and Fattening Up Your Liver.<\/a><\/p>\n<p><em>&#8220;Since the fish oils are commonly studied by comparing the supplemented animals with &#8220;control&#8221; animals receiving soy oil, corn oil, or safflower oil, which are strongly pro-inflammatory and broadly toxic, it isn&#8217;t surprising that their effects usually seem favorable. But when they are compared with saturated fats (as I mentioned in the &#8220;<a href=\"http:\/\/raypeat.com\/articles\/articles\/fats-degeneration3.shtml\">Fats and degeneration&#8221;<\/a> newsletter) or with a <a href=\"https:\/\/www.functionalps.com\/blog\/2012\/04\/03\/fat-deficient-animals-activity-of-cytochrome-oxidase\/\">fat free diet<\/a>, their effects are seen to be pro-inflammatory and toxic.&#8221;<\/em> -Ray Peat, PhD<\/p>\n<p>The fish oil mega industry as we know it today began as the paint\/varnish sector dried up when the petroleum industry took over that market. The fish oil industry had no other place to sell this waste product of fish production so they capitalized on the faulty research done by the Burrs&#8217; in the late 1920s falsely showing essentiality for these fats (it was actually for seed oil fats truthfully but fish oils are the &#8220;new&#8221; &#8220;essential fats&#8221;). This misinterpreted research gave the seed and fish oil industry grounds to market these toxic fats as &#8220;health foods&#8221; for humans.<\/p>\n<p>There is no such thing as &#8220;<a href=\"https:\/\/www.functionalps.com\/blog\/2010\/12\/19\/errors-in-nutrition-essential-fatty-acids\/\">essential fatty acids<\/a>&#8220;; the body doesn&#8217;t synthesize &#8220;essential&#8221; PUFA on its own b\/c they are toxic, not because they are essential. One unsaturated fat the body does synthesize from sugar is the protective and anti-inflammatory <a href=\"https:\/\/www.functionalps.com\/blog\/2012\/04\/10\/anti-inflammatory-omega-9-mead-acid-eicosapentaenoic-acid\/\">Omega -9 Mead Acid<\/a>, which is ironically a marker for &#8220;<a href=\"https:\/\/www.functionalps.com\/blog\/2012\/01\/14\/essential-fatty-acid-deficiency-resistance-to-traumastressshock\/\">essential fatty acid&#8221; deficiency<\/a>.<\/p>\n<p>Today, the momentum and inertia behind these products is great because of repeated marketing efforts of these industries. The brainwashing is so good that both professionals and laypersons don&#8217;t consider taking a look at both the current and historical research about the negative effects of fish oil and other PUFA. We are now at a point of unheard of chronic disease in large part due to our shift away from saturated animal fats\/coconut oil and an increase in plant-derived polyunsaturates from vegetables, beans, seed, nuts and<a href=\"http:\/\/raypeat.com\/articles\/articles\/fishoil.shtml\"> fish oils<\/a>.<\/p>\n<p><strong>Scientific Review of Fish Oils:<\/strong><br \/>\n<a href=\"http:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC3914521\/#sec18title\">Why Fish Oil Fails: A Comprehensive 21st Century Lipids-Based Physiologic Analysis<\/a><\/p>\n<p><strong>Cancer Causing:<\/strong><br \/>\nCancer Res. 1998 Aug 1;58(15):3312-9.<br \/>\nDietary omega-3 polyunsaturated fatty acids promote colon carcinoma metastasis in rat liver.<br \/>\nGriffini P, Fehres O, Klieverik L, Vogels IM, Tigchelaar W, Smorenburg SM, Van Noorden CJ.<\/p>\n<p>Nutr Cancer. 1998;30(2):137-43.<br \/>\nEffects of dietary n-3-to-n-6 polyunsaturated fatty acid ratio on mammary carcinogenesis in rats.<br \/>\nSasaki T, Kobayashi Y, Shimizu J, Wada M, In&#8217;nami S, Kanke Y, Takita T.<\/p>\n<p>J Lipid Res. 2005 Jun;46(6):1278-84.
