How could diet affect pain?

There is no strong evidence linking diet to pain severity, but some hypotheses exist. For example, it has been suggested that moving from a Western diet (high in processed foods) to a diet high in purportedly anti-inflammatory foods (e.g., fruits and vegetables) may help alleviate chronic pain. Also, consuming foods with prebiotics and probiotics that can alter the gut flora and alleviate dysbiosis (an abnormal gut microbiome) may reduce gastrointestinal pain.^[1]
