Does this sound like the set of challenges you might be facing?

  • So much of what I eat comes out of a package
  • I’ve been chasing my low mood purely from the neck up
  • On the days my stomach is off I also feel low and foggy, and I can’t tell anymore which one is driving the other
  • I’m doing everything right with food and still feel off, and I’m starting to think it’s the short, broken nights I keep brushing aside
  • I’ve heard most of the body’s serotonin is actually made down in the gut, and I want to know which everyday foods give that whole process the raw material it needs

Practices that may help

  1. Displace ultra-processed foods
    Ultra-processed foods degrade the gut lining and microbial balance that the gut-brain axis depends on.

  2. Recognize that 90% of serotonin is made in the gut, not the brain
    Gut serotonin regulates intestinal movement and signals the enteric nervous system — inadequate fiber and microbiome diversity impairs this production.

  3. Track the gut-mood signal for your own body
    The gut-brain link is real but highly individual — journal to discover your own pattern.

  4. The Gut-Brain Axis: How Your Gut Talks to Your Brain
    The gut and brain communicate continuously via the vagus nerve, immune signals, and microbial metabolites — a well-established bidirectional highway. Whether deliberately intervening on gut bacteria reliably shifts mood in healthy people is a much younger, more contested question; the mechanistic picture is solid but clinical evidence for "psychobiotics" is still preliminary.
  5. Protect sleep to protect your microbiome
    Poor sleep degrades gut microbiome diversity — the gut-brain axis is a two-way street that sleep disruption damages from the top down.

  6. Include tryptophan-rich foods to support serotonin production
    About 90 percent of the body’s serotonin is made in the gut — feeding that process starts with dietary tryptophan.

  7. Reintroduce fermented foods slowly after gut disruption
    After antibiotics or illness, a gradual return to fermented foods aids microbiome recovery without triggering digestive distress.

  8. Dietary Fiber for Mood, Made Practical
    Dietary fiber feeds gut bacteria that produce short-chain fatty acids (SCFAs), which influence the vagus nerve, the enteric nervous system, and systemic inflammation — all pathways connecting the gut to the brain. John Cryan’s gut-brain axis research shows the gut produces the majority of the body’s serotonin and communicates directly with the brain via the vagus nerve. Observational studies link high-fiber diets to lower rates of depression; direct mood RCTs for fiber specifically are limited, but the mechanism is well established.
  9. Feed your gut with fiber and fermented foods
    Eat a diversity of plants and some fermented foods to support a healthier gut microbiome.

  10. Understand the vagus nerve pathway between gut bacteria and mood
    Short-chain fatty acids from fiber fermentation signal the brain via the vagus nerve — this is the physical wiring of the gut-brain axis.
