Circulating lipopolysaccharide (LPS) binds to the ApoB region on LDL particles, preventing ApoB from being recognized and recycled by the liver, which prolongs the particle's circulation time.
"It's binding to the region called ApoB. And the ApoB part of the LDL particle is very important because that is the part of the LDL particle that gets recycled back to the liver so that your LDL levels aren't staying around forever in your bloodstream. But LPS is obscuring that ApoB and so it does not get recycled and so it stays around in circulation longer." (said at 0:47:45)
The claim that circulating lipopolysaccharide (LPS) obscures apolipoprotein B (ApoB) to block hepatic clearance and prolong LDL circulation is contradicted by structural and physiological evidence. Biophysical studies of LPS–LDL complexes demonstrate that LPS incorporation does not screen or obscure ApoB on the lipoprotein surface. Furthermore, ApoB-containing lipoproteins (such as LDL and VLDL) act as major physiological scavengers for circulating LPS, which are subsequently cleared from the bloodstream by the liver via the LDL receptor (LDLR) and excreted into bile.

"Moreover, in the LPS-LDL complexes, oligosaccharide chains of LPS screen notably neither phospholipid polar headgroups nor, what is very important, apoB. LPS-LDL complexes are suggested to be able in vivo to bind to cellular apoB/E receptors, possible LPS receptors and scavenger-receptors of macrophages (monocytes)."

"Next, LPS binding protein, phospholipid transfer protein, and other transfer proteins transfer these lipids to ApoB-containing lipoproteins, including low-density (LDL) and very-low-density lipoproteins and chylomicrons. Pathogen lipids within these lipoproteins and their remnants are then cleared from the circulation by the liver. Hepatic clearance involves the LDL receptor (LDLR) and possibly other receptors."

Studies show that higher mercury levels, which reflect higher fish consumption, are associated with higher IQ scores in children due to the benefits of omega-3 fatty acids.
"And there was even one study that was published a few years ago that showed higher levels of mercury—which was indicative of higher omega-3 intake because people that were taking in fish had higher mercury—actually was a biomarker for intelligence and they and the children had higher intelligence quotient scores, so IQ scores, if they had higher mercury, not because mercury is improving brain function, but because they were getting omega-3 fatty acids." (said at 1:06:14)
Published cohort studies investigating maternal fish intake, mercury exposure, and child cognitive development do not find that higher mercury levels serve as a positive biomarker for child IQ. Rather, observational cohort studies (such as Project Viva) demonstrate that higher maternal fish intake is associated with improved neurodevelopmental and cognitive scores, whereas higher mercury biomarker concentrations (in maternal hair or blood) are independently associated with lower cognitive scores and developmental decrements. When statistical models adjust for fish intake and mercury simultaneously, the beneficial association with fish consumption and the detrimental association with mercury exposure both become clearer.

"After adjusting for participant characteristics using linear regression, higher fish intake was associated with higher infant cognition. This association strengthened after adjustment for hair mercury level: For each additional weekly fish serving, offspring VRM score was 4.0 points higher [95% confidence interval (CI), 1.3 to 6.7]. However, an increase of 1 ppm in mercury was associated with a decrement in VRM score of 7.5 (95% CI, -13.7 to -1.2) points." (abstract, results, passage verified)

"After adjustment using multivariable linear regression, higher fish intake was associated with better child cognitive test performance, and higher mercury levels with poorer test scores. Associations strengthened with inclusion of both fish and mercury: effect estimates for fish intake of >2 servings/week versus never were 2.2 (95% confidence interval (CI): -2.6, 7.0) for the PPVT and 6.4 (95% CI: 2.0, 10.8) for the WRAVMA; for mercury in the top decile, they were -4.5 (95% CI: -8.5, -0.4) for the PPVT and -4.6 (95% CI: -8.3, -0.9) for the WRAVMA."
