Chronic Inflammation: What It Is and How Your Lifestyle Affects It

Inflammation is not inherently bad — it's the body's first-line defence response to injury, infection, and threat. Without it, you couldn't heal from a cut or fight off a virus. The problem is when inflammation becomes chronic: a persistent, low-grade state of immune activation that has no clear acute threat to respond to.

What Chronic Inflammation Is Linked To

Chronic low-grade inflammation is now understood to be a central mechanism in a remarkable range of conditions: cardiovascular disease, type 2 diabetes, Alzheimer's disease, certain cancers, depression, arthritis, metabolic syndrome, and accelerated aging. The inflammatory marker CRP (C-reactive protein) is one of the strongest predictors of future cardiovascular events.

What Drives Chronic Inflammation

• Excess visceral fat (fat around internal organs) actively produces inflammatory cytokines
• Poor sleep — even short-term sleep deprivation raises inflammatory markers
• Chronic psychological stress — activates the same immune pathways as physical threat
• Ultra-processed food consumption — via gut barrier disruption and high refined sugar
• Physical inactivity — regular exercise has direct anti-inflammatory effects
• Smoking and excessive alcohol

What Reduces Chronic Inflammation

• Regular exercise: consistent moderate exercise reduces CRP and inflammatory cytokines
• Sleep: adequate, consistent sleep is one of the most potent anti-inflammatory interventions
• Mediterranean-style diet: richest anti-inflammatory evidence base — olive oil, fish, vegetables, legumes, nuts
• Stress management: chronic stress reduction (through whatever means works for you) reduces cortisol-driven inflammation
• Omega-3 fatty acids: found in oily fish, walnuts, flaxseed — directly inhibit inflammatory signalling
• Adequate fibre: feeds gut bacteria that produce anti-inflammatory short-chain fatty acids

Foods with Anti-Inflammatory Evidence

• Oily fish (salmon, sardines, mackerel, herring) — omega-3 fatty acids
• Olive oil — oleocanthal has NSAID-like anti-inflammatory properties
• Berries — high polyphenol content
• Leafy greens — vitamins K and C, polyphenols
• Turmeric — curcumin has modest direct anti-inflammatory effects
• Green tea — catechins with anti-inflammatory activity
