Food for PTSD and trauma.

PTSD is the nervous system getting stuck in threat-response mode after trauma. The amygdala runs hot, the prefrontal cortex gets outcompeted, the HPA axis dysregulates, and inflammation rises. Food matters because each of these systems responds to nutritional inputs.

Neuroinflammation. PTSD is associated with elevated inflammatory markers in brain and blood. Anti-inflammatory eating patterns reduce symptom severity in trials.

HPA-axis dysregulation. Cortisol patterns flatten or invert in PTSD. Stable meal timing reinforces circadian regulation of cortisol. Magnesium supports HPA recovery.

Gut-brain axis. Trauma alters gut microbiome composition. Dysbiotic guts send alarm signals up the vagus that the traumatized brain reads as ongoing threat. Fermented foods and fiber diversity support.

GABA-glutamate balance. Traumatized brains have glutamate/GABA imbalance. Foods supporting GABA (magnesium, apigenin, L-theanine) help with hyperarousal.

Sleep disruption. Core PTSD symptom. Nightmares, hypervigilance, insomnia. Food timing and tryptophan-rich dinner help.

Omega-3 fatty acids — Moderate evidence

Post-trauma supplementation reduced PTSD development in prospective trial (Matsuoka et al., 2015).

Magnesium — Emerging evidence

HPA-axis support reduces hyperarousal.

Curcumin — Emerging evidence

Small trials show symptom reduction.

GABA support (magnesium, L-theanine, apigenin) — Moderate

Calming for hypervigilant nervous systems.

Probiotics — Emerging evidence

Gut-brain axis support for anxiety component.

Omega-3 fatty acids — 3+ times per week

Reduce neuroinflammation. Some evidence for PTSD-specific effect — trial showed omega-3 supplementation reduced PTSD symptom development after acute trauma.

Magnesium-rich foods — daily

HPA-axis regulation. PTSD nervous systems run hot — magnesium damps it.

Fermented foods — daily

Gut-brain axis. Trauma disrupts gut microbiome; restoration supports nervous system regulation.

Leafy greens and legumes

Folate and magnesium.

Turmeric with black pepper

Curcumin reduces inflammation and has small-trial evidence for PTSD symptom reduction.

Chamomile, passionflower teas

GABA support for hyperarousal.

Eggs and fatty fish

Choline, D, B12, omega-3s.

Bone broth, glycine-rich foods

Nervous system support, sleep support.

Dark chocolate, berries

Polyphenols reduce oxidative stress.

Alcohol. PTSD self-medication pattern. Worsens nightmares, sleep disruption, depression. Major relapse trigger.

Caffeine. Heightens hypervigilance. Most PTSD nervous systems are already over-activated.

Ultra-processed foods. Chronic inflammation compounds PTSD-related neuroinflammation.

Erratic eating. Often appears alongside PTSD. Destabilizes everything else.

Stable meals anchor a nervous system that doesn't feel safe.

No alcohol. No caffeine after breakfast.

Warm, grounding foods preferred. Stews, soups, bone broth.

Evening wind-down ritual.

Eat before hunger triggers panic.
