K-Moss This is a great comment, and to add to this, everything they say about "vitamin" A is a lie. I want to direct your towards the work of Grant Genereux, researcher Anthony Mawson, and Dr. Garrett Smith. To sum quickly, Grant was suffering from eczema, chronic kidney disease, and other health ailments (chronic fatigue, insomnia, etc) and basically reverse engineered his way into discovering he had vitamin A toxicity that caused all of this. He tried to get the intake of vitamin A in his diet as low as possible and reversed all his health issues. He's been on that same low vitamin A diet for now 10 years and is in great health. His blood levels have showed he has a "deficiency" of "vitamin" A for 6-7 years now, which shows two things - 1. We don't need any "vitamin" A to live. 2. It took him 3-4 years to deplete all the vitamin A in his liver to reach a deficiency in the blood, so it builds up in the system and takes a really long time to deplete. Grant writes extensively about his health (including eye health) on his blog - ggenereux.blog
Him, Garrett, and Anthony Mawson all believe vitamin A is not essential and that the early rat studies done on vitamin A are flawed. The "vitamin A free diets" they would feed rats would be deficient in zinc and taurine, and it was actually VERY high in vitamin A in the form of retinoic acid, considered the active form of vitamin A that they never test for (they only test retinol and caratenoids). It was the lack of zinc and taurine that destroyed eye health and the high vitamin A in the most destructive form (retinoic acid). Retinoic acid is also synonymous with Isotretinoin, which is what the drug Accutane is. When they give you Accutane, you are taking the active form of "vitamin" A. Look into "Accutane horror story", "Accutane ruined my life", etc to see what taking the direct, most potent form of "vitamin" A can do to destroy the body.
I've been on the low vitamin A diet for 8 months now and have seen major improvements - can now tolerate screens much longer now before fatigue sets in, feel more resilient, higher pain tolerance, much more emotional stability (feel like not much bothers me anymore), have way less sinus congestion, feel happier, feel more like me, like if I were a window that was stained and dirty, I feel like that window is starting to become clean and all that grime that was attached to it is being washed away, and I overall feel less inflamed. Keep in mind I never took accutane, never really got into eating liver, etc. It's just so ubiquitous that even if you didn't focus on intaking it, you likely have an excess of it that is causing your body issues.
In the future I will make an extensive post on the topic. Not sure yet if I can advise people to do the diet, as that entails a responsibility to people's health, which I'm not really comfortable with. But I hope I got some gears turning for some people who read this, and helped direct you towards a path that gets you healing.
