Part of the challenge is complexity: there are 100,000 times more microbes in your gut than humans on this planet, writes Emeran Mayer in The Mind-Gut Connection. There are also more immune cells inside of our stomachs than in blood and bone marrow, which makes what we put into our mouths so important. Our diets might affect our brains more than the other way around. As Mayer puts it,
Your gut microbes are in a prime position to influence your emotions, by generating and modulating signals the gut sends back to the brain.Humans are collectively experiencing increased rates of anxiety, which is now the planet's most pervasive psychological disorder. Increased stress has numerous destructive tendencies in our guts, including the alteration of contractions, transit rates between our stomach and large intestine, and blood flow. When that blood is transporting extra cortisol due to an increase in our corticotropin-releasing factor (CRF), the result is increased storage of visceral fat, decreased function of our immune system, and, of course, anxiety.
