the statement about Vitamin A was actually a joke. Of course this anecdotal report is no proof of the relationship between Vitamin A and blindness.
Also kind of strange that he is deficient in Vitamin B12 when he eats pork. I mean unless he has some absorption problems it should not be an issue.
And Vitamin D...I mean half of the population or more is deficient in Vitamin D...
I got this link from Chris Masterjohns Twitteraccount. And he responded to one tweet:
"So you don't think B12 deficiency causes optic neuritis? You don't think vitamin A deficiency causes blindness? Or you just disagree with the lab results that he was B12 deficient? Or you think there is vitamin A in fries?"
in other articles they said he was mainly eating fries pringle’s and white bread with occasional salami, so salami was not a normal addition in his diet.. that’s can easily cause b12 deficiency, along with everything else mentioned of course. also, as ones growing they use b12 much more quickly then an adult, so the tiny tiny amount in salami is nowhere near enough. Also, i can’t possibly imagine a diet worse then fries chips and white bread. pufa and added iron, the two worst things. i feel bad for the kid, parents should be punished for that
