@irie Like every article that has ever been created with this exact headline, if you read it, it says "although all of the nutrients CAN be found in plants..."
@mactonite@irie I'm not going to re-read all those C-words again, but the last 5 times I looked it up, they were either found in plants, not actually essential, or your brain naturally produces enough of it you don't need an external source. Anyway I hate people who can't code assuming I must be retarded because I don't eat meat.
@alex@irie plants don't have any vitamins: a, b6 (pyridoxal, pyridoxamine), b12, d3, k2 amino acids: creatine, carnitine, carnosine, taurine (considered unessential by the soy industry but essential for childhood brain development) heme iron, coq10, cla
2/3rds of published, peer reviewed, scientific studies fail rreplication. That means whenever you read a headline about some new "scientific" discovery (outside of the hard sciences, which have a much better hit-rate, at least for now) it is twice as likely to be false as it is to be true. Our institutions of learning and knowledge production are in shambles. #replocationcrisis#epistemicimpoverishment
@alex@irie i made a point specifically to address your concern which i assumed you would have. you totally skipped over everything else too, it's objectively wrong to state any of those listed are found in plants.
No, they were administering beta carotene and looking at conversion rates. They saw an association of those SNPs with a lower conversion rate (not "no conversion"). The SNPs provide a plausible explanation of lower conversion rates (though there are many other plausible explanations).
What this has to do with vitamin A actual deficiency (VAD, which is very very low in developed countries like the UK) isn't clear. There is no indication that those with the SNPs were VAD.
They suggest that people with those common SNPs may benefit by increased pre formed vitamin A intake in countries where VAD is common. They may, they may not. VAD is a very complex problem that is tied to the host of generally poor living conditions in poor countries.
@mittimithai@irie@alex the study i linked show there is no conversion for individuals on a genetic basis. they must eat animal foods. retinol supplements are toxic.
@mittimithai@irie@alex according to their estimated levels of blood vitamin a which is set too low as synthetic vitamin a supplements (often marketed to vegans) are toxic. the study on vitamin a toxicity was done on retinol supplements, not food. this has nothing to do with true deficiency which is a state of need, nothing to do with quotas.
@mittimithai@irie@alex the supplement industry is unregulated so vegan corporations can sell cyanide to you gullible retards and call it b12. no, carrots have no vitamin a. that's false advertisement. there are genetic variations in beta carotene metabolism meaning a vegan diet is genocide against those who cannot convert it.
