A lot of sympathy for yours and lots of other cool guys on this forum.
It's a look. Here are some ideas. I'll take an extreme example, will abound in your direction. I can not stand seafood, if I do not eaten ... at the edge of the sea. The fish ... if they are not frozen ... etc. I need
fees. This is a personal will. So, if I eat this type of non fresh, I get sick. Whereas before I could eat everything without problem (except Given my allergies have disappeared after correcting my food bowl for almost 20 years without remission).
Let's go further, let's say I can not eat any animal products under pain of very severe allergies. (It is possible, there is even sensitive issues that could die after eating cream cacahuette ... because they are allergic ...)
A product may or may not be toxic, surely even fatal for some people, especially if THE SUBJECT HAS PRIORIZED considered / decided something to be "harmful" for his organism, it could thus become harmful because it was detected as such (therefore , the body not seeking to assimilate it would retain all its toxic properties), especially if the subject is forced to consume it ... someone can even be convinced that he is going to die and end up passing from life to death, without having swallowed anything ...
We know because sometimes this process is not reversible ...
Did well the proof! There would be so close chemical interaction between the psyche and physiology.
And even spiritual dimiension around the planting, harvesting, respect of nature, sharing the meal (etc) can have an effect ... To say that our lifestyles are far from ideal. .. First track!
But it is not yet "admitted" as always scientific.
There are still many things in chemistry, who are like that.
So obviously I can not exclude your words. On the contrary.
The scientific question is "generalization" / "repetition" of the experience! wrongly considering that if it can not repeat ... so is that there is nothing. This is of course false. Just as it is necessary thus reasoning in the report "
Cause and effect"It is not because we have not identified the cause of an effect, the cause in question would not exist. And yet it is the claims of the dogma of "scientifiscme" ... Second floor!
All this to get to the third track (there are others ...)
In the foods that we (all) eat, there are a lot of "alicatoxics", it all depends on the metabolism that absorbs them, sage (and other herbs like the toe), the skin of plants, yeasts, products animals, certain other fermented products, alcohol (also existing in natural form), caffeine that you mention, but also theine, and other alkaloids, rapid sugar (especially refined) ... In short, we live dangerously, because in addition, some of these foods carry products that are beneficial to us, which means that we are OBLIGED to consume them ...
So yes, I totally agree with your last post.
Besides, at that moment, my body is saturated and it'll have to make me a "takeover".
So develop your idea if it is compatible with "longevity", and warning the reader about the effort needed to achieve it in the long run (as I understand it).
