Chronic inflammation drives most major diseases. Here's how to structure an anti-inflammatory diet — specific foods, supplements, and habits that reduce systemic inflammation.
Inflammation is not inherently bad — it's essential. Acute inflammation is your body's first-line defence against infection, injury, and foreign invaders. The problem is chronic low-grade inflammation: a persistent, smouldering immune activation that operates below the threshold of obvious symptoms but over years contributes to cardiovascular disease, type 2 diabetes, Alzheimer's disease, certain cancers, depression, and accelerated ageing. Elevated inflammatory markers — CRP, IL-6, TNF-alpha — are associated with virtually every major chronic disease.
The good news: diet is one of the most powerful modifiers of chronic inflammation, and the changes required are straightforward.
Salmon, mackerel, sardines, herring, and anchovies are rich in EPA and DHA (omega-3 fatty acids) — the most potent dietary anti-inflammatory compounds identified. EPA and DHA are converted to resolvins, protectins, and maresins — lipid mediators that actively resolve inflammation. Meta-analyses consistently show omega-3 supplementation reduces CRP, IL-6, and TNF-alpha. Aim for 2–3 portions of oily fish per week, or supplement with 1–2g EPA+DHA daily. See our omega-3 guide for full details.
The cornerstone of the Mediterranean diet, EVOO contains oleocanthal — a phenolic compound with similar COX-1 and COX-2 inhibitory activity to ibuprofen. A 2019 meta-analysis found higher olive oil consumption associated with significantly reduced CRP and IL-6. Use cold-pressed, extra virgin olive oil (not regular olive oil or vegetable oil blends) and don't heat it above 180°C. 2–3 tablespoons daily is associated with the strongest effects in Mediterranean diet research.
Curcumin — turmeric's primary bioactive — inhibits NF-κB, the master regulator of inflammatory gene expression. A 2016 meta-analysis of 8 RCTs found curcumin supplementation significantly reduced CRP and IL-6. The critical caveat: curcumin has very poor bioavailability on its own. Piperine (from black pepper) increases curcumin absorption by 2,000%. Use turmeric with black pepper, or take a supplement with piperine. See our turmeric guide for the full evidence review.
Blueberries, strawberries, raspberries, and blackberries are packed with anthocyanins — flavonoids with potent antioxidant and anti-inflammatory activity. A 2019 systematic review found berry consumption significantly reduced CRP and other inflammatory markers. Frozen berries are nutritionally equivalent to fresh and more cost-effective.
Spinach, kale, chard, and rocket are rich in vitamin K (which regulates inflammatory cytokine production), magnesium (deficiency promotes inflammation), and sulforaphane (in cruciferous varieties like kale) — a potent NRF2 activator that upregulates the body's own antioxidant defences.
EGCG (epigallocatechin gallate) — green tea's primary catechin — significantly reduces NF-κB activity and pro-inflammatory cytokines. A 2017 meta-analysis found green tea consumption significantly reduced CRP and IL-6. 2–3 cups daily achieves meaningful EGCG levels; matcha (concentrated powdered green tea) delivers the most.
Beta-glucans in Lion's Mane, Reishi, Chaga, and Turkey Tail modulate immune activity and reduce inflammatory signalling without immune suppression. Particularly relevant for gut inflammation and systemic immune dysregulation. See our guide to functional mushrooms.
Diet alone can't reverse chronic inflammation if other drivers are unaddressed:
An anti-inflammatory diet is fundamentally a whole-food, Mediterranean-adjacent pattern: oily fish 3x/week, olive oil daily, abundant vegetables, berries, legumes, minimal ultra-processed food and refined sugar. Add turmeric with black pepper, green tea, and functional mushrooms. Address sleep, stress, and movement. Supplement strategically with omega-3, vitamin D, magnesium, and curcumin. Chronic inflammation is reversible — and these interventions have the clinical evidence to prove it.

View NECTA IMMUNITY →Oily fish (salmon, mackerel, sardines) are the most potently anti-inflammatory foods — their EPA and DHA omega-3s directly produce anti-inflammatory compounds (resolvins, protectins) and measurably reduce CRP and IL-6 in clinical trials. Extra virgin olive oil (oleocanthal as a natural COX inhibitor), turmeric with black pepper, and blueberries round out the most evidence-backed anti-inflammatory foods.
Measurable reductions in inflammatory markers like CRP can occur within 4–8 weeks of consistent dietary change. Some studies show improved inflammatory markers within 2 weeks of increased omega-3 intake. Full benefits of a sustained anti-inflammatory dietary pattern take 3–6 months to manifest. The key is consistency — occasional healthy eating surrounded by an inflammatory dietary pattern has minimal effect.
The most pro-inflammatory dietary patterns are high in: ultra-processed foods (refined grains, seed oils, emulsifiers), refined sugar and HFCS, excess omega-6 seed oils (sunflower, corn, soybean oil), trans fats, and alcohol. The omega-6:omega-3 ratio is particularly important — the typical Western diet has a ratio of 15:1 when 4:1 or lower is associated with significantly lower chronic disease risk.
Yes — refined sugar promotes inflammation through multiple mechanisms: formation of AGEs (advanced glycation end-products), direct activation of NF-κB (the master inflammatory transcription factor), and by feeding gut bacteria that produce pro-inflammatory metabolites. Epidemiological studies consistently link high sugar intake with elevated CRP and other inflammatory markers. This includes fruit juice and honey, not just table sugar.
