Inconsistent findings in omega-3 health benefit studies may be due to reliance on self-reported dietary intake, which is less accurate than measuring blood levels.

“we've seen people over 20 who are not taking fish oil which is pretty so there's some interesting biology”

“but since then studies have been inconsistent in showing the health benefits for omega-3s this may be partially due to differences in steady design especially when they rely on people self-reporting how much fish they ate people often misjudge how much or how often they eat a particular food and the amount of omega-3s and fish can vary quite a bit too but blood levels can provide a much more accurate measure of how much omega-3s a person actually eats”

“probably an even bigger variability is the variability uh in response to taking an omega-3 so we look at the delta the change in omega-3 index at different with different dosage groups and it can be you know on average it's a very nice the higher the dose the higher the omega-3 index but if you look at the individual display across those increases some people on the set on a 1800 milligrams of epa dha that might go up from an omega-3 index to four to four point three others might go up from four to eight i mean it's just huge variability”

“yeah right and this is something we we don't understand yet um there is quite a bit of background variability”
