Firstly, without having read the book, myself, I'm still quite certain the language Huggins used to relay his findings was not "You MUST eat meat, all vegetarians MUST stop what they are doing OR ELSE". Though I'd be interested if anyone who has a copy could make a quote from the exact excerpt we're talking about so that we might discern fact from fiction.

Whilst living in the U.S., at the time, I visited a pig farm. It wasn't a farm, actually, it was a factory. A slaughter house. The notion of killing an animal for consumption, in and of itself, does not particularly bother me. We are, after all, omnivores by definition, and there are many who will argue (with good evidence) that eating vegetarian is unhealthy and contradictory to our biology -- but that's very clearly debatable. In any event, I was so appalled with the treatment these animals underwent that I became vegeterian for approximately four years. I'm a pretty slim guy as it is and over the course of my vegetarian diet I began to waste away, despite all efforts to keep on weight. I innevitably resorted back to eating meat, with a focus on free range and "organic" meat. Since moving back to Europe I am thankful that the meat I purchase never comes from factories, rather, very natural farms where antibiotics are virtually unheard of and one need only drive through the country side to see where the bulk of their meat products are coming from. I feel quite comfortable eating an animal which I knew has had a healthy lifestyle. Interestingly enough, animals raised in such conditions actually taste better than what you find in the states -- creatures who live pitiful lives caged in boxes, fowl with their beaks severed so they can be force-fed, thus fattening them for more meat, and animals given growth hormones/steroids to hasten their growth cycle. Here, one can stroll past a meat store and find a whole pig hanging from the window on display and, frankly, it doesn't bother me in the least. That animal led a healthy, happy life and none of it goes to waste.

Nevertheless, I would imagine one can sucessfully detox without relying on meat for B-vitamins, taurine, or other nutrients derived from meat (though it may be quite challenging). But it's important to remember that everyone's body chemistry is different. One man's cure is another man's poison. You must find out for yourself what your own body needs to sustain nourishment and even detox. Algin is an excellent source but if you're opposed to purchasing gelatin products, you might try incorporating seaweeds into your diet, rather than seaweed/algae supplements (which is essentially what Algin is). Here's an interesting link on the wonders of marine plants.

I don't think you should lose your faith in science altogether, Demi. Gravity is irrifutible fact, the state of REM whilst dreaming is irrifutible fact, the intoxicating effects of alcohol are irrifutible facts, and on and on. Sure, there's a lot that's debatable and plenty that's downright incorrect, but that does not make science, as a whole, erroneous (just some parts).
