It is a little-known fact that high-sugar diets can wreak havoc with neurotransmitter levels in a number of ways, including through disruptive effects on the kynurenine pathway. 
The kynurenine pathway helps regulate the activity of serotonin, melatonin, dopamine, GABA, and glutamate—all important neurotransmitters in symptoms of psychiatric disorders. Diets too high in refined carbohydrate promote inflammation and oxidation (see above), which shifts the brain into emergency mode.
The kynurenine pathway responds to the alarm by stealing tryptophan away from its serotonin and melatonin synthesis duties to help generate more glutamate instead. As a result, serotonin, melatonin, and GABA activity go down, dopamine activity goes up, and glutamate levels can skyrocket to up to 100 times their baseline levels. You can think of glutamate as the brain’s gas pedal—keeping your foot on this gas pedal for too long too often can cause what is called “glutamate excitotoxicity,” which is very damaging to the brain. Ketogenic diets have been shown to regulate neurotransmitter levels and reduce glutamate toxicity.
Protect your precious neurons from glutamate overdrive.
