Dave Hirschman 2010-03-14T14:47:37Z 2010-03-14T18:31:44Z <p>In <a href="http://paleohacks.com/questions/1919/half-a-gram-of-fish-oil-per-10-lbs-of-bodyweight-per-day" rel="nofollow">Half a gram of fish oil per 10 lbs of bodyweight per day?!</a> Melissa commented that "When I took fish oil in the winter I unfortunately learned of its immunosuppressive effects." </p> <p>I recently learned that Cod Liver Oil has too much Vitamin A, so we switched to Carlson's Fish Oil. But is even that a bad idea? Is fish oil immunosuppressive only if it's CLO with Vitamin A? Is it immunosuppressive only if you take too much? Or should fish oil not be used at all? I could definitely benefit from a stronger immune system!</p> http://paleohacks.com/questions/2091/is-fish-oil-immunosuppressive/2094#2094 Answer by Bread-Eating Beelzebub for Is Fish Oil Immunosuppressive? Bread-Eating Beelzebub 2010-03-14T15:23:08Z 2010-03-14T15:23:08Z <p>To confuse everything, I switched out fish oil for fermented CLO. I figured the Vitamin D would help boost my immune system. Sure enough, I haven't gotten sick this cold season. I don't plan on sticking with the CLO after it warms up though. </p> http://paleohacks.com/questions/2091/is-fish-oil-immunosuppressive/2095#2095 Answer by jm054 for Is Fish Oil Immunosuppressive? jm054 2010-03-14T15:24:44Z 2010-03-14T15:24:44Z <p>A quick search on PubMed says that the answer to your question is yes. I urge you to do the research and do the cost benefit analysis to see if it is worth it to you.</p> <p><a href="http://www.ncbi.nlm.nih.gov/pubmed/1833105" rel="nofollow">http://www.ncbi.nlm.nih.gov/pubmed/1833105</a></p> http://paleohacks.com/questions/2091/is-fish-oil-immunosuppressive/2098#2098 Answer by David Moss for Is Fish Oil Immunosuppressive? David Moss 2010-03-14T15:52:42Z 2010-03-14T15:52:42Z <p>The main rationale for fish oil being immunosuppressive isn't about fish oil per se, it's about omega-3 being anti-inflammatory. Chronic inflammation is, of course, very bad indeed, but acute <a href="http://en.wikipedia.org/wiki/Inflammation" rel="nofollow">inflammation</a> is integral to the immune system. There must be some reason why we evolved inflammatory responses and it presumably wasn't so our bodies could kill us!</p> http://paleohacks.com/questions/2091/is-fish-oil-immunosuppressive/2113#2113 Answer by Jay for Is Fish Oil Immunosuppressive? Jay 2010-03-14T18:27:59Z 2010-03-14T18:27:59Z <p>At low doses, this isn't a big problem. In my opinion, the risk of chronic inflammatory disease (heart disease, stroke, cancer, neurodegenerative diseases, autoimmune diseases) outweighs the risk of infection. You can limit the fish oil to a gram or so per day and if you are able to drastically restrict your n-6 PUFAs. Remember inflammation and immunity are two sides to the same coin. The result makes perfect sense. </p> http://paleohacks.com/questions/2091/is-fish-oil-immunosuppressive/2115#2115 Answer by Ed for Is Fish Oil Immunosuppressive? Ed 2010-03-14T18:31:44Z 2010-03-14T18:31:44Z <p>Whether something is beneficial (usually anti-inflammatory) or harmful (usually immunosuppressive) depends on the person, the situation and the dosage of the agent in question. I said "usually" because sometimes immunosuppression is good, eg. after an organ transplant. I don't believe the "dose-response curve" of fish oil has been accurately worked out. I believe that fish oil supplements are beneficial at some lowish dose if you don't eat much fish, and that the risks/harms outweigh the benefits at some higher dose. Dr. Harris recommends 1 to 2 tsp. of CLO per day if you don't eat fish, and you're eating supermarket meat ( <a href="http://www.paleonu.com/get-started/" rel="nofollow">http://www.paleonu.com/get-started/</a> ). This is about 1 to 2 grams of O3 PUFAs per day.</p>
