Chronic pain is not simply a local tissue problem. It is characterised by systemic inflammation, central sensitisation, and a dysregulated stress response. All three of these have dietary drivers. Changing what you eat will not cure a structural problem that requires clinical intervention, but failing to address the dietary drivers of inflammation means that any clinical intervention is working against a headwind.
The Key Inflammatory Food Drivers
- Refined carbohydrates and added sugar: raise insulin and inflammatory cytokines including interleukin-6 and TNF-alpha
- Refined vegetable oils high in omega-6: linoleic acid from soybean, sunflower, and corn oils is the precursor to arachidonic acid, a pro-inflammatory eicosanoid
- Trans fats: still present in some processed foods, directly impair membrane function and raise systemic inflammation
- Alcohol: breaks down to acetaldehyde which drives gut permeability and systemic inflammation
- Ultra-processed food additives: emulsifiers such as carboxymethylcellulose disrupt gut barrier integrity and increase inflammatory load
The Key Anti-Inflammatory Food Pattern
Anti-inflammatory eating is not about individual superfoods. It is a dietary pattern. The consistent findings across rheumatology and pain research point to the same elements: olive oil as the primary fat, oily fish two to three times per week, colourful vegetables at every meal, berries and other polyphenol-rich fruits, turmeric and ginger used regularly in cooking, and minimal refined carbohydrates and processed foods.
Measurable Outcomes in Pain Populations
A systematic review published in the journal Nutrients in 2021 found that dietary anti-inflammatory index scores were significantly inversely associated with chronic pain intensity across multiple population studies. Patients in the highest quartile of anti-inflammatory dietary pattern had substantially lower pain scores than those in the lowest quartile. The effect was independent of body weight, though weight reduction from dietary improvement compounds the benefit.
