Grant Generoux claims his chronic kidney disease ("incurable, fatal") was healed by his low vitamin A diet. We know from studying technical outages and systems failures that the more checks and balances we put in place, the weirder the cause of any outage will be - because only the weird things get through where the gaps between the checks all line up. Of course the claim isn't wrapped up in a simple package with conclusive proof and widely agreed on - if it were, it would be mainstream accepted knowledge. Why hasn't it been noticed? Because the damage is cumulative and long term - years or decades. Because it's fat soluble, so the effects are modified by the amount of fat eaten at the same time. Because the effects are diffuse - it's not showing up in one single organ. Because the effects look like other things - autoimmune attacks, for example. Because historic mistakes in studies have caused 'vitamin A toxicity' to get mixed up with 'Vitamin A defficiency'. Because it varies with different people with different liver storage capacity and historic retinol compound buildup. Because it may be masked by protective effects of Vitamin C or other dietary components. Because stopping eating it offers no quick fix, healing might be "wait years for damaged cells to die and new ones to grow". Because there's no money in telling people to eat less of somethings, so there's little industry funding incentive or research grants. Here for example, one of the other people who agrees with the claim of Vitamin A being harmful shows their working: https://ggenereux.blog/discussion/topic/biotransformation-of-retinol-finally-revealed/ https://ggenereux.blog/discussion/topic/biotransformation-of... - Under Discussion it says "It is now no longer difficult to imagine how retinoic acid [ed: Vitamin A/retinol related compound] could cause auto-immune disease, since the data appears to show that retinoic acid is essentially a pro-inflammatory cytokine that is stored in the liver and, once the liver is saturated, in different types of tissue all over the body, especially in epithelial cells that constitute blood–tissue barriers, and in adipocytes, both of which were shown to express STRA6 (Amengual, Zhang et al. 2014). [... explanation continues]" I am never going to study enough chemistry, biology, biochemistry, statistics, medicine, to be able to make a judgement call of my own about that page, let alone all the other studies people have linked to and pulled apart. At least it's cheap and relatively easy and low risk to try, but even if my health improves (I don't have kidney damage) it could easily be attributable to many other factors - placebo, for example.
