A part of PTSD recovery that is often overlooked is one’s diet.
When stressed, anxious, fearful, fatigued we tend to reach for comfort foods, highly processed foods and alcohol or drugs just to feel a little better.
This is NOT a PTSD friendly diet. Your body is working hard to deal you’re your stress and anxiety. Your diet is just as important as all of the other aspects of your recovery program.
Mediterranean‑style diet shows the strongest evidence of being helpful for people living with PTSD, particularly because of its effects on inflammation, the gut microbiome, and overall brain health.
This isn’t a cure — but research suggests it can meaningfully support symptom management and resilience.

Mediterranean diet and PTSD symptoms
A 2023 study found that people with higher PTSD symptoms tended to have lower adherence to the Mediterranean diet. This diet pattern was also linked to the presence of PTSD‑protective gut bacteria. These microbes support metabolic pathways (like pantothenate and CoA synthesis) that appear protective.
Why this matters: PTSD is increasingly understood as involving chronic stress, inflammation, and gut–brain axis disruption. Diets that reduce inflammation and support microbial diversity may help buffer these effects.
Diet quality tends to decline with PTSD
Long‑term research on over 50,000 women showed that those with high PTSD symptoms experienced less improvement in diet quality over 20 years compared to those without trauma. This suggests PTSD can make healthy eating harder — and that improving diet may be a meaningful part of recovery. Source: The Centre for Nutritional Psychology
Nutrition factors and PTSD risk
Population‑level data from the Canadian Longitudinal Study on Aging also found associations between nutrition factors and PTSD, suggesting diet plays a role in vulnerability and symptom expression.
What this means in practical terms
Foods and patterns that appear most helpful
These align closely with the Mediterranean diet pattern supported by research:
High in:
- Vegetables, fruits, legumes, nuts, seeds
- Whole grains
- Olive oil as the primary fat
- Fish and omega‑3–rich foods
- Fermented foods (yogurt, kefir, kimchi) to support gut health
Moderate in:
- Poultry, eggs, dairy
Low in:
- Processed foods
- Refined sugars
- Red and processed meats
- Highly processed fats (trans fats, seed‑oil–heavy fried foods)
Why this pattern helps
- Supports gut–brain axis health
- Reduces systemic inflammation
- Stabilizes blood sugar, which affects mood and stress reactivity
- Provides nutrients involved in neurotransmitter regulation (B vitamins, omega‑3s, polyphenols)
What to consider next
Diet can be a powerful support, but it’s only one part of PTSD recovery. If you’re thinking about making changes, it can help to start with small, sustainable shifts — especially since PTSD itself can make appetite, motivation, and routine harder to manage.
These small steps forward are vital to managing your disorder. Your body will appreciate the change; your mind will see this as a victory in that other changes can emulate.
Can you do this? Yes, You Can!!
