All the experienced members of the forum are required to elaborate this work and give their valuable suggestions after reading this research.
I request all the members, please first read the book, expand your notion of thinking regarding this research, and let's try to discuss this problem here, I am not proposing and presenting any theory here until most of us read this research https://ggenereux.blog/wp-content/uploads/2016/10/extinguishing-the-fires-of-hell2.pdf, after reading this we can understand each other. Practically I personally have applied some techniques from this research and those have proven successful specifically in dealing with mental health issues but I am not going to list anything until solid evidences of its effectiveness are found.
Hi Ali Hamza,
I understand that your intention is to help, but here are some considerations for you to ponder on :
1. If you carefully read the book of this guy, and read the disclaimers, he himself is not sure if his theory is valid, and what really helped him.
2. Nowhere in his book did I see a mention of a blood test result about his vitamin A level, either before his no-vitamin-A diet or after. When you talk about vitamin A toxicity ( hypervitaminosis A), for hundreds of pages, you should have your blood level tested, at the least. He does not even mention retinyl ester testing, which is more accurate still than Vit A blood level to identify hypervitaminosis A ( see
https://en.wikipedia.org/wiki/Hypervitaminosis_A#Tests ). That is a major flaw in his presentation.
3. POIS is not eczema, so no direct conclusions for POIS can be drawn from his self-experiment.
4. If this has been beneficial for him, this does not mean that it will be beneficial for others, even for those having the same health problem ( eczema) that he has.
5. He challenged his health condition with food containing vitamin A, but I would have preferred to see him try a vitamin A supplement as a challenge. This would have been more in line with his hypothesis.
6. Hypervitaminosis A is something real, but it comes only from ingestion of too much preformed vitamin A ( retinol ), like from too much fish liver oil or from too much liver from animal sources. But you cannot have toxicity from veggies and fruits, which contains beta-carotene, a pro-vitamin A, not already formed vitamin A. The body will change beta-carotene to vitamin A only when needed, so it cannot cause toxicity ( I suggest you read this excellent article for details:
https://en.wikipedia.org/wiki/Hypervitaminosis_A ). In his book, Mr.Genereux seems to be oblivious to this fact and advises avoiding fruits and veggies, which is not good advice, considering what we know about their many benefits, and considering they cannot contribute to vitamin A toxicity.
The fact that this guy seems quite intelligent and is a prolific writer ( he obviously likes to take 12 pages to make a point that would need only one page, in my opinion), that does not make him a health professional. He makes many guesses, that could be called "educated guesses", but that are not verified. If you pile up guesses upon guesses, you get a very shaky hypothesis, in the end.
Vitamin A absorption can vary from one person to another, due to genomic differences. Those who have a better absorption may need less vitamin A, but I am not convinced that a regular, balanced, diet could end up causing vitamin A toxicity. If this occurred with a balanced diet, it would be a very particular case, and a genome sequencing of this individual would be appropriate to do, in order to look for any particular SNPs ( genomic permutations) that could explain this level of sensibility to preformed vitamin A.
This does not mean that he did not get better, but it may not be for the reason he thinks. For example, he mentioned he had a flare up from tomatoes, but as explained above, tomatoes cannot cause vitamin A toxicity, the beta-carotene in them is just not changed into vitamin A ( in this case, he may have considered the effect of acidic and spicy foods on eczema, I think). So, his hypothesis would need refinements and would need much more rigorous testing, and with many other subjects, not just himself.
Maybe it would be better to share some information about your own case, Ali Hamza. Do you personally have POIS, and what symptoms do you have, and what have you tried up to now to relieve it ? Also, if you tried any of what is presented in this book, what was it, exactly, and what level of relief did you get? For what symptoms? If you have good results, how long has it been since you have those results? This kind of information may be of interest for our members here
