Thanks for your comments. I'm aware that in the conventional view, the causes of scoliosis are attributed to the factors you mention, and I don't disagree that this would be the case for many people. Looking at your list, many of these causes could be attributed to pre-natal nutrition in the mother, or childhood deficiencies. Weston Price apparently found no evidence of scoliosis or similar deformities in any of the peoples he visited during his studies.
From what I understand scoliosis could very well be caused by diet. I believe in some cases, at certain critical stages of growth or maturation, that if the body is not adequately nourished, that the body will actually "rob" the bones of minerals and nutrients to perform the tasks it needs. This softens and weakens the bones and can cause them to bend - especially combined with muscular tension or spasms which pull the spine further out of alignment. Many people who develop scoliosis have a normal spine all through childhood and into their early teens, and it is only after a certain age that the scoliosis "mysteriously" develops for no apparent reason. This was my case - I had a normal spine (and no abnormalities in leg length) until I turned 14, when a very slight curve developed. By the time I reached my early twenties it had progressed to the point where I was getting substantial pain. The doctors had no explanation for why I would have developed this condition.
I never was able to comprehend why everyone could agree that a condition such as rickets could be caused by nutritional deficiencies, but no one seems to be willing to admit that a curved spine could be a similar condition? Leg bones and spine are both weight bearing structures in the body, and if they are weakened then surely they will either bend, or become brittle. I have been reading up on nutritional links to bone strength and have found this is the only logical explanation for my scoliosis.
Unfortunately I think because I am now over 30, that even if I changed my diet now, my curvature would probably not change much as it has been there for so long. But that is not to say I won't try!! Any small benefit I can get is better than no improvement at all! I am looking at an integrated approach that includes dietary changes and supplementation, yoga and stretching, massage, exercise, occasional osteopathy, etc.
So I guess I was just wondering if anyone else had tried this approach and had any improvement!?
