Experts believe that gut dysbiosis is a cause of environmental illness. Changes in the gut biome can be caused by antibiotic use, environmental insults from chemicals in food and water and high fat and high sugar diets. These changes lead to morphological changes in the wall of the intestines that allows for easier translocation of harmful bacteria. It is believed that translocation may be one significant cause of chronic fatigue syndrome. In addition, it is believed that dysbiosis may lead to neuroinflammation that is believed to be a major source of symptoms in chronic fatigue and fibromyalgia.
Numerous studies published in the recent past have shown that consumption of some fruits and herbs may improve gut health. Research has demonstrated that anthocyanins in berries may counteract dysbiosis. In addition, they also have anti-neuroinflammatory properties and allow for better communication between the gut and the brain. Lastly, they alter tryptophan metabolism increasing the neuroprotective
metabolite kynurenic acid. (1) Incidentally, this pathway also produces the antioxidant 3-hydroxyanthranilic acid which inhibits inflammatory proteins by activating Nrf2. (2)
