But we live in 2010 year, not in paleo times. We've got a lot of more bacteria, somo of the mutated, some of them man-made - it doesn't matter. What matters is that THEY EXIST and we've got to live with them.
The same bacteria can be nothing for us and for others could by deadly.

    I could never stand public pools that use lots of chlorine and chlorinated showers.  My breathing passages and eyes always bothered me in those situations.  I don't like drinking tap-water either.  Not sure, I guess I'd agree, drinking is not as bad as breathing it.

That's not true. Put the meat into the glass jar, seal it thoroughly, do not air it for a month or so and you'll probably get that Clostridium botulinum. Go to laborabory and they'll tell you.

Chloroform?  Chlorine, I think you meant.

But the parasite has made reactions between the chemicals in the food, which give it energy, but render it useless to the fish. The fish then gets the waste-products. For the faeces of the parasite to become useful again, they would have to be acted upon by bacteria/fungi, then taken up by plant-life which will not be present within the fish.

This wouldn't be the issue however in this case, but it could be relevant to large gut-parasites such as tape-worms in humans.

So what happens when these parasites eat all the bad shit inside you? If you are very sick, will they grow tremendously in size? And then when there is no bad tissue left, and you are on a raw diet which keeps you from producing bad tissue, do they start eating good tissue? Do they die? Just curious.

Spearman, let us know how your experiment goes!

  Yes. That is a very good point made by Aajonus. That said the study did involve special parasites designed solely for pigs(ie they only survive for some weeks in the human gut as a result, last I checked).  And maybe it only benefits those with IBS as opposed to other symptoms. Whatever the case, continuing research on the Hygiene Hypothesis theory re the benefits of bacteria and parasites continues to show that many of AV's most controversial claims re high-meat etc. have ultimately been proven right.

Well, my own (raw-and pasteurised dairy-allergies manifested themselves in all sorts of ways, indeed they were the primary source of my troubles other than the cooked animal food. My chronic fatigue/anxiety- and other  adrenal-related issues were directly the result of raw and pasteurised dairy as were various skin and eye-problems(eg:- severely bloodshot eyes), along with the severe constipation and wrecked digestive system(though, to be fair, the dairy was worse than any cooked animal food I ate, as regards constipation). Dairy, raw or otherwise, also almost made me lose all my teeth, led to severe muscle-wastage  etc. After many years, I've come to accept that a small minority may  do well on raw dairy, but I'm pretty sure it's a tiny minority, given the fact that so many of those who've claimed to me that they were doing fine on a little raw dairy, have, subsequently, over the years, grudgingly admitted to me, that they didn't do so well after all, with it, and felt better without.

Not true. Some of us here on the forum eschew both of these and have still made marked strides in repairing our digestion and our health. 

   You're welcome.  

    I actually had other stuff health-wise going on too, but the day I described I was totally fatigued.  

    I remember, well, my son got sick a few years ago, and after trying everything alternative we could find, we then were trying with a doctor.  

    This doctor gave him about eight different types of medicines all at the same time.  My son's digestion got totally ruined when previously it was mostly only reflux during this illness.  Anyway, the doctor was wrong and to save my son from possible death my son and I decided he should not take four of the medicine and go to a good traditional acupuncturist.  

    One treatment, and his digestion was worlds better.  

    I hear acupuncture started when soldiers looked dead during a battle, and they were laid at the side on rocks to keep the bodies out of the way until after the battle, or something like that.  I don't know if it's true.  Anyway, enough of them would recover from appearing dead after laying on the rocks.  Supposedly acupuncture was developed by observing this.  So, I think something based on rocks might be considered somewhat paleo.  

    Have you tried acupuncture?  No pharmaceuticals involved and my son got well enough even though he did not drink the acupuncturist's herbs.
