There is a plethora of evidence supporting the contention that pathogens can only thrive in an acidic environment. While Wikipedia is sometimes helpful, it is far from an authority on these matters and is often over-represented by naysayers with an agenda (isn't Scn Inc banned from editing for that very reason?)....
I dont think anyone disagrees that good nutrition plays a key role in good health and can help ill people heal. However if these juices and so forth you promote were so effective Im not sure why so many health nuts are dead.
Placebo effect is VERY powerful, more powerful than real medicine sometimes. People make the error in believing placebo means it's false or didn't really work, which isn't true - placebo effect can mean it worked but not because of some chemical properties but because the person believed it would or other reasons.
I'm always kind of taken aback when people who were conned by Scientology, and were then able to see it for what it truly is, go on to promote some other scheme as a "cure all" or totally effective when it lacks real, significant scientific data. It seems the CoS fallacy of "if it's true for you..." still applies when you think something that worked or was beneficial to you must automatically mean it will work miracles for everyone!
We rely on the scientific method, with stable results that can be repeated for a reason - it's the best we have for proof or fact in this world. Personal antidotes or statistically insignificant results are viewed with skepticism for a reason.
Obviously someone ill with cancer needs to follow a healthy diet and stay strong, no medical doctor would argue with that, but that is not going to cure their cancer 99% of the time. There are hundreds of thousands of people who have died because they chose to follow some scientifically unproven homeopathic remedy rather than medically established treatments. Unfortunately you only hear about the relative handful of people who managed to go into remission following some homeopathic cure on websites and forums which promote them.
Steve Jobs felt his decision to try some highly touted homeopathic remedies for the first few months after he was first diagnosised with cancer probably cost him his life. Had he aggressively fought his cancer with traditional medical methods from day one he may have survived. Sadly, those critical first months he wasted on "alternative treatments" hoping to avoid the admittedly very serious and painful surgeries traditional medicine urged him to do. (He said his fear of surgery and the life altering results of said surgeries he desperately wanted to avoid played a major role in his initial decision to pursue alt treatments. Later on he viewed the side effects of the recommended surgeries as a small price to pay for survival).
So when someone like Jobs, who was highly intelligent and had the money and connections to get the very best kind of nutrition and homeopathic therapies eschews them because they didn't work people should pay attention. At least pay more attention than to the 2 people on a alternative medicine website swearing some exotic fruit juice cured them of cancer.
It's just dangerous to promote or think of something as a cure all for everyone when there is little in the way of real proof. I think it gets people, like me, who have watched loved ones die slowly of terminal cancer, angry when someone who pipes up (knowing 0 about the medical facts of her case) declares if she just got herself a juicer and started eating right she would be fit as a fiddle in no time!
It's ignorant and dangerous talk, especially when you are dealing with a population of people (cancer patients & their families) who are scared and desperate for answers or anyone who will tell them what they want to hear - which is we can cure this, they will live. doctors are extremely pragmatic and don't like to give false expectations and ethically can't make promises of cures or results. Unfortunately, charlatans and even well meaning people don't usually don't show the same restraint and will say those magic words families so badly want to hear.
The traditional medical establishment isn't perfect and they certainly don't have all the answers but the at least we know the answers and therapies they do offer have statistically known, relevant, tested results. For now it's the best we got and the survival rates for cancer have been steadily climbing thanks to their difficult, arduously tested, research.
As long as alternative therapies don't interfere or take the place of real medical advice and treatment, I see no harm and possibly benefit. But it becomes a problem when these medically untested therapies are promoted as "the answer," give false hope or encourage people to ignore medical advice or treatment in favor of their methods.
(FYI When a friend of mine had cancer and explored alt treatments far too many on the surface would say follow Dr. advice, but as she got deeper into it things changed to "well you can't expect this to really work like it should because of all those poisons from chemotherapy in your body, if you'd cleanse yourself of the poisons and then do our method then it would def work." This was the case with a lot of the homeopathic and alternative therapies out there - if results were lacking it was implied it must be due to the harmful western medicine your are using and going 100% homeopathic was the only real way.)
