Poor gut health can particularly affect the basic physiological processes as well as mental processes such as learning, memory and mood.  Changes in healthy 

gastrointestinal micro-biome can occur from long-term exposure to antibiotics, certain medications such as steroids, c-section births, processed foods, sugary diets, and stress, among other things.

 

Disruption in gut micro-biome can lead to increased permeability of the gastrointestinal tract also known as "leaky gut", autoimmune reactions, nutrient deficiencies, and exposure to toxins.  The result can be an array of physical and psychiatric symptoms.  The good news is that studies show that changes in diet and adding beneficial gut bacteria have the potential to positively impact brain function, boost mood, and reduce anxiety or depression.
