What Causes Food Intolerances?
Nobody really knows for sure what causes food intolerances. Research is beginning to help us uncover some of the likely ...
Here at Healthpath, we’re proud to offer evidence-based advice. However, we’re aware that science can seem a bit impenetrable and dry. Boring, even.
We also believe that education is the first step to regain control. We read a lot of scientific papers, so we thought it would be a good idea to create a digest (no pun intended) of some of the key research.
We hope these plain-English versions bring the science to life and—even more importantly—help you address your symptoms for good.
An article on fibromyalgia and gut health.
Fibromyalgia is a chronic condition that’s associated with musculoskeletal pain, fatigue and mood disturbances. The cause is poorly understood, which means diagnosis and management can be a challenge for both patients and doctors.
The author of this paper looked at lots of different studies on fibromyalgia. Based on the available research, they propose that low serotonin levels and fructose malabsorption can indirectly trigger the symptoms of fibromyalgia. They then discuss how dietary changes could support those with fibromyalgia.
1. Serotonin is an important neurotransmitter (chemical messenger) involved in regulating several physical and emotional processes within the body. It’s created in the body using a protein building block known as tryptophan. Consequently, variable intakes of tryptophan-rich food and problems with tryptophan absorption can affect how serotonin is made by the body.
2. Fructose malabsorption is the inability to absorb fructose (a type of sugar) when broken down in the gut. The author proposes that this, along with low concentrations of tryptophan, interferes with how the body makes serotonin. This influences symptoms of fibromyalgia in susceptible people.
3. Dietary treatment that includes a fructose-free diet combined with tryptophan-rich food may be a possible treatment strategy for those with fibromyalgia. However, as this paper was a literature review, the evidence to support this theory would need to be robustly tested in a clinical trial with fibromyalgia patients.
A large component of the body’s serotonin is found in the gut. A dietary approach that focuses reducing fructose—which is found in high fructose corn syrup (HFCS) products, fruit, honey and soft drinks—may be necessary for some. However, dietary recommendations would need to be accessed based on an individual’s symptoms and history.
