The full first tweet is “(THREAD) Evidence that enriched refined grains promotes obesity. A major overlooked factor in the 1980s obesity epidemic.” At the bottom of the thread are links to the author’s website, presumably with more information.<p>There are certainly other factors in the obesity epidemic — endocrine disruptors, fake foods, PUFA, etc — but maybe the fortification of flour is a major factor?<p>I posted the other day about my friend’s tragic experience with Arizona’s involuntary mental health industry [0]. Tl/dr: My friend is diagnosed as chronically disabled. The doctors think she must take anti-psychotics for the rest of her life. I have videos proving she was actually fine 2 weeks before she ran out of alcohol. After maybe ~3 years of forced tranquilizers (“anti-psychotics”), she figured out for herself that she’s a poor methylator who can’t turn the provitamin folic acid into something usable. She said using a methylated form of Vitamin B-9 (L-Methyfolate) was like flipping a switch from “depressed” to “not-depressed”. (This has been forgotten. Now they just keep her on the tranquilizers without the vitamin.)<p>[0] <a href="https://news.ycombinator.com/item?id=33310757" rel="nofollow">https://news.ycombinator.com/item?id=33310757</a> (some good responses in this thread) (edit: this comment referenced this tweet, but I couldn't find it at the time.)<p>My retweet [1] said, “I've made an effort to avoid fortified flour for 11+ years, to avoid excess iron. Didn't appreciate how problematic fortification is until I ran across this thread. White flour: sub-optimal Fortified white flour: tragic (poor methylators are harmed by folic acid) #ScienceMistake”<p>[1] <a href="https://twitter.com/JamesKnochel/status/1584795534182977537" rel="nofollow">https://twitter.com/JamesKnochel/status/1584795534182977537</a><p>Ask HN: Is fortified flour a #ScienceMistake ? If so, how can this be brought to Science’s attention?
