Finding out the root causes of post polio syndrome

As you know post polio syndrome is a devastating disease, affecting so many people around the world. However, we don't seem to be combatting the root causes of post polio syndrome. My friend Rob thinks it's the food dye, but I'm more of the opinion that regulating raw goat cheese is the main culprit here. I need your professional opinion on how to combat this very urgent problem. Any ideas?
