I absolutely agree @Afraser that keeping healthy and fit and eating a good diet, and if necessary supplements are a good thing in addition to, but not as a replacement for, proven treatments. For me, it becomes a bit dicey when some people are convinced that if they do, eat and exercise all the right things, they will be cured. This idea that Big Pharma and the medical profession are in some sort of unholy alliance to make money and keep people unwell (but still alive for long enough to squeeze them financially dry) is just so silly. I think that sometimes the baby is being thrown out with the bathwater where there is this tunnel vision about 'natural' therapies to the exclusion of scientifically proven therapies and treatments.
