According to a recent medical study some food chemicals, such as MSG and Aspartame commonly found in everyday foods, may exacerbate fibromyalgia and IBS symptoms…
A recent study conducted at Oregon Health & Science University…tested patients who had the diagnosis of both fibromyalgia and irritable bowel syndrome. The hypothesis was that monosodium glutamate and aspartame irritate the bowel, exacerbating fibromyalgia symptoms.
The results demonstrated that there was a significant worsening of fibromyalgia symptoms (including IBS) in those patients when they were taking MSG compared to the placebo… There also is medical evidence that indicates changes in diet can significantly improve the pain associated with fibromyalgia.
Eliminating these compounds (MSG and Aspartame) from the diet might improve the symptoms of irritable bowel syndrome and at the same time improve fibromyalgia symptoms in some patients.
