Errr, sorry what what may be perceived as a rant
Almost every single link connecting arthritis to uric acid comes back to this site (same for asthma too).
Arthritis isn't caused by uric acid unless you count "Gouty arthritis" which is actually regular Gout and nothing to do with arthritis. Asthma also has no connection to his theory as I would love it to so simple.
Theres more than a few "weasel words" in that link (actually misrepresentation is probably a better phrase) regarding cancer cells being acidic. Snake Oil seems to be a phrase which applys to that guy (sorry).
Yes indeed raised O2 concentrations will kill cancer cells but the same applys to regular cells too, it's just that many cancer cells are more sensitive, the same sensitivity to O2 concentrations applies to many bacteria (or indeed whole people under the correct conditions as any qualified diver will tell you.)
This is the main reason hospitals do no longer put premaure babys into O2 rich incubators as common practice.
As I also seem to remember O2 is one of the processes that white blood cells uses to kill invaders.
There is an alternate mindset which says you need to lower the oxygen in body tissue (thats partally what anti oxidants are about)
http://www.alternative-doctor.com/anti-ageing/oxygen.html for a conflicting point of view.
Sorry for the rant but I hate misrepresentation (and Ioinizers.org is full of it). The only thing that was missing was the conspiracy theory regarding goverment, pharmacutical companys and healthare people
To pick up in part of Jonathans post, balancing your diet can work wonders for avoiding triggers or to prevent the build up an excess of things which we could well do without. As these can reach trigger levels over a course of time (without us being aware of the trigger in the 1st place)
Unfortunitely for us moderation in all things is the truely healthy option, but humans are not too good at moderation :(
In my case I have to be very careful about sulfites in red wine and beer as even one glass of the wrong beer or wine can cause me issues for days.
