Episode Summary In this deep-dive episode, Dr. Ravi Kumar explores why omega-3 fatty acids are foundational to human health—touching on their biochemistry, evolutionary history, robust clinical evidence, and practical strategies for optimizing intake. You’ll learn: What “omega-3” really means and why your body can’t make these fats on its ownEarly discoveries by George and Mildred Burr in the 1920sThe Inuit paradox: high-fat diets with low cardiovascular diseaseLandmark trials such as REDUCE-IT and EVAPORATE demonstrating cardioprotective effectsRoles across the lifespan: brain development, mood regulation, eye health, immune function, muscle maintenance, liver health, skin integrity, and moreEvolutionary insights from traditional populations and enzymatic conversion of ALA → EPA/DHAPractical guidance on food sources, supplement types (triglyceride vs. ethyl ester, krill, algal oil), dosing, safety (oxidation, contaminants), and certification (IFOS) Practical SuggestionsDaily baseline: Aim for ≥2 g combined EPA + DHA (with at least 1 g EPA)High-dose therapy: 3–4 g/day EPA-rich for hypertriglyceridemia, arthritis, depressionPregnancy: At least 500 mg DHA daily (algal oil option for vegans)Food sources: Prioritize small, low-contaminant fish (sardines, anchovies, mackerel); include wild-caught salmon sparinglySupplement selection: Choose triglyceride-form fish oil, IFOS-certified; watch for oxidation (peroxide/anisidine levels) and contaminant removal via molecular distillationLifestyle context: Reduce omega-6 seed oils to improve ALA→EPA/DHA conversion; honor ancestral dietary patternsReferenceshttps://pmc.ncbi.nlm.nih.gov/articles/PMC3657456/https://pubmed.ncbi.nlm.nih.gov/25604397/https://pmc.ncbi.nlm.nih.gov/articles/PMC7037798/https://pmc.ncbi.nlm.nih.gov/articles/PMC7759779/https://www.sciencedirect.com/science/article/pii/S000291652312911X?via%3Dihubhttps://journals.plos.org/plosone/article?id=10.1371/journal.pone.0044926https://pmc.ncbi.nlm.nih.gov/articles/PMC9228863/https://pubmed.ncbi.nlm.nih.gov/16825680/https://www.sciencedirect.com/science/article/pii/S0002916523294861https://pubmed.ncbi.nlm.nih.gov/12442909/https://www.sciencedirect.com/science/article/pii/S0002916523275462?via%3Dihubhttps://pubmed.ncbi.nlm.nih.gov/7270479/https://pmc.ncbi.nlm.nih.gov/articles/PMC7761957/https://pmc.ncbi.nlm.nih.gov/articles/PMC4480667/https://pmc.ncbi.nlm.nih.gov/articles/PMC3021432/https://pmc.ncbi.nlm.nih.gov/articles/PMC7561009/https://pubmed.ncbi.nlm.nih.gov/15857162/https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0088103https://pmc.ncbi.nlm.nih.gov/articles/PMC8832668/https://pmc.ncbi.nlm.nih.gov/articles/PMC3138218/https://pmc.ncbi.nlm.nih.gov/articles/PMC6155966/https://pubmed.ncbi.nlm.nih.gov/22023985/https://www.jbc.org/article/S0021-9258(19)36227-1/fulltexthttps://pubmed.ncbi.nlm.nih.gov/28694914/https://pubmed.ncbi.nlm.nih.gov/12771037/https://pubmed.ncbi.nlm.nih.gov/24553997/https://pubmed.ncbi.nlm.nih.gov/11895157/https://pubmed.ncbi.nlm.nih.gov/28261950/https://pubmed.ncbi.nlm.nih.gov/21569104/https://pubmed.ncbi.nlm.nih.gov/26353789/https://pubmed.ncbi.nlm.nih.gov/22591891/https://pubmed.ncbi.nlm.nih.gov/21961774/https://pmc.ncbi.nlm.nih.gov/articles/PMC9406129/https://pubmed.ncbi.nlm.nih.gov/27541690/https://www.frontiersin.org/journals/medicine/articles/10.3389/fmed.2024.1440479/fullhttps://pmc.ncbi.nlm.nih.gov/articles/PMC2812063/https://pubmed.ncbi.nlm.nih.gov/15555528/https://pmc.ncbi.nlm.nih.gov/articles/PMC7362115/https://pubmed.ncbi.nlm.nih.gov/28900017/https://pubmed.ncbi.nlm.nih.gov/20434961/https://pmc.ncbi.nlm.nih.gov/articles/PMC10447496/https://pubmed.ncbi.nlm.nih.gov/23515006/https://pubmed.ncbi.nlm.nih.gov/17240089/https://pubmed.ncbi.nlm.nih.gov/17556695/https://pubmed.ncbi.nlm.nih.gov/12509593/https://pmc.ncbi.nlm.nih.gov/articles/PMC9355374/https://pmc.ncbi.nlm.nih.gov/articles/PMC4054797/https://www.ahajournals.org/doi/full/10.1161/CIR.0000000000000709https://pubmed.ncbi.nlm.nih.gov/32860032/https://www.nejm.org/doi/full/10.1056/NEJMoa1812792https://www.ahajournals.org/doi/10.1161/CIRCULATIONAHA.105.581355https://www.jacc.org/doi/10.1016/j.jacc.2008.04.018https://pubmed.ncbi.nlm.nih.gov/4102857/https://pubmed.ncbi.nlm.nih.gov/38982829/
