✓Well SupportedPasture-raised egg yolks, animal fats (butter, tallow, ghee), and the fat in grass-fed steak contain significant amounts of utilizable omega-3 fatty acids.✓Well SupportedModern humans have over 20% linoleic acid in their fatty tissues, compared to 2-3% historically.✓Well SupportedIodine deficiency is primarily caused by goitrogens like sulforaphane and other isothiocyanates that compete with iodine at the ionic level in the thyroid.✓Well SupportedEPA and DHA can be obtained from egg yolks, and ALA can be converted to DHA when linoleic acid from seed oils is not in excess.Well Supported

Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

✓

Diets high in polyunsaturated fatty acids inhibit the synthesis of DHA from ALA.

✓Well SupportedSufficient iodine intake can be obtained from sources like egg yolks, dairy, and muscle meat, without needing seafood.

✓Well SupportedHuman diets likely evolved to contain about 2% polyunsaturated fatty acids, compared to current intakes of 10-20% or more.

✕Not SupportedFish oil is considered oxidized and undesirable, with no solid evidence supporting the purported benefits of high doses (4-6 grams).

◐Partially SupportedThe benefits of omega-3s may stem from their ability to rebalance omega-6 levels, as high omega-6 intake can inhibit omega-3 production.

◐Partially SupportedAdequate omega-3 intake can be achieved without consuming fish, thereby avoiding potential toxins.

✕Not SupportedSeafood is not necessary for iodine intake.

◐Partially SupportedFarm-raised fish, common in sushi, may contain contaminants like PCBs but potentially fewer microplastics or PFAS than wild-caught fish.

◐Partially SupportedEliminating seafood and considering beef and ruminants as better alternatives may lead to being a less toxic version of oneself.
