Inflammation & Diet
The diet-inflammation connection — how food drives or suppresses the chronic inflammation underlying most modern disease
Chronic low-grade inflammation — distinct from the acute inflammation of injury and infection — is now recognised as a central driver of the most significant modern diseases: cardiovascular disease, type 2 diabetes, cancer, neurodegenerative disease, autoimmune conditions, depression, and accelerated ageing. Unlike acute inflammation, which is localised, purposeful, and self-limiting, chronic systemic inflammation is diffuse, persistent, and ultimately destructive — a smouldering fire that gradually degrades organ function across decades. Diet is one of the most powerful modulators of this inflammatory state — and the evidence for dietary modification as a therapeutic strategy for chronic inflammatory conditions is among the strongest in nutritional medicine.
Chronic inflammation is driven by multiple converging factors: excess body fat (particularly visceral adipose tissue, which secretes pro-inflammatory cytokines including TNF-alpha, IL-6, and leptin); gut dysbiosis and intestinal permeability (allowing bacterial endotoxins including LPS into the bloodstream, triggering the innate immune system); oxidative stress (free radical damage exceeding antioxidant capacity); advanced glycation end-products (AGEs formed by glucose binding to proteins, abundant in processed foods and in hyperglycaemic states); and specific dietary patterns.
The relationship between diet and inflammation operates through multiple pathways: the ratio of omega-6 to omega-3 fatty acids (the typical Western diet has a ratio of 15–20:1 vs the ancestral ratio of approximately 4:1 — omega-6 fats are precursors to pro-inflammatory eicosanoids while omega-3 fats produce anti-inflammatory resolvins and protectins); refined carbohydrate load (driving postprandial glucose spikes that generate oxidative stress and AGEs); fibre intake (dietary fibre feeds bacteria that produce anti-inflammatory short-chain fatty acids including butyrate); and specific phytochemicals in plant foods with direct anti-inflammatory action.
The Mediterranean Diet
The most thoroughly researched dietary pattern with confirmed anti-inflammatory and disease-preventing effects — associated in multiple large prospective studies with reduced cardiovascular mortality (the landmark PREDIMED trial showed 30% reduction in major cardiovascular events), reduced risk of type 2 diabetes, lower depression rates, better cognitive function, and reduced overall mortality. Characterised by high olive oil consumption (primary fat source), abundant vegetables and legumes, whole grains, fish (2+ times weekly), moderate red wine, and minimal processed food, red meat, and refined carbohydrates. Consistently outperforms low-fat dietary patterns in clinical trials.
Omega-3 Fatty Acids
The anti-inflammatory omega-3s — EPA and DHA from marine sources (oily fish, algae), and ALA from plant sources (flaxseed, walnuts, chia) — are among the most extensively researched dietary interventions for inflammation. EPA and DHA are direct precursors to specialised pro-resolving mediators (SPMs) — resolvins, protectins, and maresins — that actively resolve inflammation rather than merely suppressing it. Clinical evidence supports omega-3 supplementation for: rheumatoid arthritis (symptom reduction comparable to NSAIDs), depression (particularly with high EPA), cardiovascular risk reduction, and cognitive preservation in ageing.
Polyphenols
Plant polyphenols — the vast family of phytochemicals including flavonoids, anthocyanins, catechins, curcumin, resveratrol, and quercetin — modulate inflammation through multiple pathways including NF-κB inhibition (reducing production of pro-inflammatory cytokines), antioxidant activity, and gut microbiome support (polyphenols are selectively fermented by beneficial bacteria). Foods richest in anti-inflammatory polyphenols: extra-virgin olive oil, berries (particularly blueberries and cherries), dark chocolate (70%+), green tea, turmeric, red cabbage, and most deeply coloured fruits and vegetables.
Inflammatory Foods to Reduce
The foods most consistently associated with pro-inflammatory patterns: refined carbohydrates and added sugar (drive postprandial glucose spikes, AGE formation, and dysbiosis); industrial seed oils high in omega-6 (sunflower, corn, soybean, safflower — used extensively in processed foods and fried foods); processed meats (associated with increased inflammatory markers and colorectal cancer risk); alcohol in excess; and ultra-processed foods generally (associated with gut dysbiosis, increased intestinal permeability, and elevated inflammatory markers). The elimination of these categories may matter as much as the addition of anti-inflammatory foods.
Food is not just calories and macronutrients — it is information that speaks to the genome, the microbiome, and the immune system. What we eat is the most powerful pharmacological intervention most people make daily.
