I try to educate that coincidence in a study (meaning that even if there is a statistically significant correspondence) is not "proof" of causality or even conditionalism, but epidemiology. Now this can help one see a few things, and if you can try certain changes in your life-style and eating that help, than maybe it can be a lasting effect, at least for you. The problem with correlation, is that almost every change a person makes has some beneficial effects for about 2-4 months and then the effect changes. This seems to relate to one's endogenous reward system of endorphins and inner neurotransmitter release. But as these effects routinely fade, it seems to be a temporary emotional effect. Now I am not saying that the relief, even temporarily of suffering is not a good thing, but, and here's my rub - I get a bit upset about these things because the CAM (complementary and alternative medicine) has become a profit-making industry that often preys on suffering and vulnerable people.
So here's my mild rant. Any thought / feelings about this?
