Inflammaging — the term coined by immunologist Claudio Franceschi to describe the chronic, sterile, low-grade inflammation that characterises ageing — is increasingly recognised as a central driver of age-related disease. Unlike the acute inflammation of infection or injury, which is protective and self-limiting, inflammaging is a persistent background state of immune activation that gradually damages tissues, impairs cellular function, and promotes the major diseases of ageing — cardiovascular disease, type 2 diabetes, Alzheimer's disease, cancer, and sarcopenia. Diet is one of its primary modulators.
What Causes Inflammaging
Inflammaging has multiple origins that accumulate with age. Cellular senescence: aged cells that have stopped dividing but remain metabolically active, secreting pro-inflammatory cytokines (the 'senescence-associated secretory phenotype' or SASP). Gut microbiome changes: reduced microbiome diversity and increased gut permeability with age allow bacterial endotoxins to enter circulation, driving chronic immune activation. Mitochondrial dysfunction: damaged mitochondria release signals interpreted by the immune system as 'damage-associated molecular patterns' (DAMPs), triggering inflammatory responses. Accumulating glycation products: advanced glycation end-products (AGEs) from both dietary sources and internal glucose-protein reactions activate inflammatory receptors. The British Nutrition Foundation ageing and inflammation research acknowledges all of these mechanisms in its healthy ageing nutritional guidance.
The Anti-Inflammatory Dietary Pattern for Ageing
The Mediterranean dietary pattern is the most extensively studied anti-inflammatory dietary approach for older adults, consistently reducing circulating inflammatory markers (CRP, IL-6, TNF-alpha) in intervention trials. Its anti-inflammatory effects operate through multiple pathways: olive oil's oleocanthal inhibits COX-1 and COX-2 (the same mechanism as ibuprofen); omega-3 fatty acids from fish reduce arachidonic acid availability for inflammatory prostaglandin synthesis; dietary fibre supports the gut microbiome diversity that maintains gut barrier integrity; and abundant polyphenols from vegetables, fruits, and olive oil directly reduce NF-kB inflammatory signalling. The British Dietetic Association recommends the Mediterranean pattern as the dietary approach with the strongest anti-inflammatory evidence for older adults.
Specific Anti-Inflammatory Foods for Over-50s
Turmeric and curcumin: NF-kB inhibitory activity with modest but real anti-inflammatory evidence in human trials. Better absorbed with black pepper (piperine enhances bioavailability 20-fold) and fat. Walnuts: contain ALA, polyphenols, and vitamin E that consistently reduce inflammatory markers. Dark leafy greens: vitamin K1 reduces inflammatory cytokine production. Berries: anthocyanins have strong anti-inflammatory effects through multiple pathways. Olive oil: phenolic compounds in extra virgin olive oil (not standard olive oil) provide the most concentrated anti-inflammatory polyphenol intake in the diet. The British Nutrition Foundation polyphenol and inflammation research supports these specific food choices.

Frequently asked questions
Is inflammaging reversible, or is chronic low-grade inflammation an inevitable consequence of ageing?
Inflammaging is substantially modifiable, not fully inevitable. Studies of centenarians and elderly populations following Mediterranean-type diets show significantly lower inflammatory markers than age-matched controls. Dietary change, exercise, sleep optimisation, and gut microbiome support can reduce circulating inflammatory markers measurably. Cellular senescence accumulates irreversibly with age, but the amplification of inflammaging by dietary and lifestyle factors is a modifiable component.
Does curcumin supplementation produce meaningful anti-inflammatory effects, or is the food amount too small to matter?
Curcumin has genuine NF-kB inhibitory activity in laboratory settings, and clinical trials show modest but real reductions in inflammatory markers at supplemental doses of 500-1000mg daily. The amount of curcumin in typical culinary turmeric use is insufficient to replicate supplementation effects. Bioavailability is significantly enhanced by black pepper (piperine) and fat, making golden milk or turmeric in cooked dishes with these additions more bioactive than turmeric alone.
How do ultra-processed foods drive inflammation specifically, rather than just adding calories?
Ultra-processed foods promote inflammation through several non-caloric mechanisms: emulsifiers disrupt gut mucus layers, increasing intestinal permeability and bacterial translocation; advanced glycation end-products formed during high-heat processing activate inflammatory receptors; low fibre content starves the gut bacteria that produce anti-inflammatory short-chain fatty acids; and artificial additives have been shown to alter gut microbiome composition in ways that increase inflammatory signalling.
Does chronic inflammation directly cause Alzheimer's disease, or are they just associated?
The relationship is mechanistically plausible but causality has not been definitively established. Neuroinflammation — mediated by brain-resident immune cells called microglia — is a consistent feature of Alzheimer's pathology, and inflammatory cytokines promote tau phosphorylation and amyloid accumulation. Whether inflammation initiates the disease or amplifies existing pathology is still debated. Anti-inflammatory dietary approaches are associated with lower dementia risk in cohort studies, though intervention trial evidence is limited.
Are there reliable blood markers that an individual can use to track whether their anti-inflammatory diet is working?
High-sensitivity CRP (hs-CRP) is the most practical blood marker for tracking systemic inflammation, available through GP testing or private laboratory services. IL-6 and TNF-alpha are more specific inflammatory cytokines measurable in research settings. For most people, dietary intervention trials use hs-CRP as the primary endpoint. Reductions of 20-40% in baseline hs-CRP are achievable through combined Mediterranean dietary pattern, exercise, and sleep improvements over 3-6 months.
