“Need” is a funny concept. You don’t need to eat seafood. You don’t need an appendix or legs, either.
For example, Association of marine omega-3 fatty acid levels with telomeric aging in patients with coronary heart disease (Farzaneh-Far et al., 2010)
Telomere length is believed to be a biomarker of aging: the shorter your telomeres, the faster you’re aging. In the study, they measured telomere length in white blood cells and EPA+DHA in whole blood at baseline and again 5 years later.
Quartile 1: EPA+DHA = 2.3% of the fatty acids in whole blood.
Quartile 2: 3.3%
Quartile 3: 4.3%
Quartile 4: 7.3%
Potential confounders: quartile 4 was comprised of educated rich white old non-smokers with low levels of inflammation, but the statisticians assure us those variables were controlled for… so there’s that.
You might be thinking: Bill-man, I don’t feel like getting my Omega-3 Index tested, how much seafood will put me in that fourth quartile?
