Fibromyalgia and Nutrition
Key Takeaways
At present, no diet is recognized as an official treatment for fibromyalgia. However, certain nutritional approaches appear promising.
The low FODMAP diet may be relevant for people with fibromyalgia who also experience symptoms of irritable bowel syndrome. Meanwhile, the Mediterranean diet appears to be a promising avenue for improving certain symptoms and quality of life, although the evidence remains preliminary.
In all cases, the goal should be to adopt a balanced, enjoyable, and sustainable eating pattern tailored to individual needs rather than imposing multiple dietary restrictions that lack strong scientific support.
*FODMAPs are fermentable carbohydrates that are partly responsible for causing symptoms in people with irritable bowel syndrome (IBS). For more info, read this article.
