Anxiety and depression are linked to poor gut health and inflammation. The gut-brain axis connects the digestive system to the brain, so an imbalanced gut microbiome and chronic gut inflammation can affect mental health. Gut inflammation can disrupt neurotransmitter production, like serotonin, which is largely produced in the gut. Conditions like IBS and food intolerances can exacerbate stress and mood disorders. A study in the Journal of Affective Disorders found that 65% of individuals with anxiety and depression have gut microbiome imbalances. Another study in Psychosomatic Medicine showed that improving gut health reduced anxiety and depression symptoms by 25%.
