Inflammation is not inherently bad. Acute inflammation is a necessary immune response that fights infection and repairs tissue damage. The problem is chronic, low-grade inflammation: a persistent, systemic state that damages tissues, accelerates ageing, and drives the development of nearly every chronic disease. Researchers have coined the term "inflammaging" to describe this process, and it is increasingly recognised as one of the central mechanisms of biological ageing.

Chronic Low-Grade Inflammation

Unlike the redness, swelling, and pain of acute inflammation, chronic low-grade inflammation operates below the threshold of obvious symptoms. It is detectable through blood markers like high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), and tumour necrosis factor-alpha (TNF-alpha), but it rarely announces itself through symptoms until significant damage has accumulated.

Sources of chronic inflammation include excess visceral fat (adipose tissue is an active endocrine organ that produces inflammatory cytokines), poor dietary patterns high in processed foods, refined sugars, and industrial seed oils, gut barrier dysfunction allowing bacterial endotoxins into the bloodstream, chronic psychological stress elevating cortisol and inflammatory markers, insufficient sleep reducing anti-inflammatory processes, and sedentary behaviour reducing the anti-inflammatory effects of regular movement.

CRP as a Marker

High-sensitivity CRP is the most accessible and useful marker for tracking systemic inflammation. It is a standard blood test available through any GP. An hs-CRP below 1.0 mg/L is considered low risk. Between 1.0 and 3.0 suggests moderate inflammation. Above 3.0 indicates elevated systemic inflammation that warrants investigation and intervention.

For longevity-focused clients, tracking hs-CRP over time provides an objective measure of whether anti-inflammatory dietary and lifestyle strategies are working.

Omega-6 to Omega-3 Ratios

The ratio of omega-6 to omega-3 fatty acids in the diet significantly influences inflammatory status. Omega-6 fatty acids (primarily from vegetable oils like soybean, corn, and sunflower oil) are precursors to pro-inflammatory eicosanoids. Omega-3 fatty acids (from fish, flaxseed, and walnuts) produce anti-inflammatory mediators called resolvins and protectins.

The ancestral human diet is estimated to have had an omega-6 to omega-3 ratio of roughly 1:1 to 4:1. Modern Western diets, driven by the prevalence of vegetable oils in processed foods, often exceed 15:1 or even 20:1. This imbalance creates a pro-inflammatory biochemical environment.

Practical corrections include replacing vegetable oils with olive oil, avocado oil, or butter for cooking, increasing oily fish consumption to two to three servings per week, reducing processed food intake (the primary source of excess omega-6), and supplementing with high-quality fish oil providing 1 to 2 grams of combined EPA and DHA daily.

Anti-Inflammatory Foods

The most potent dietary anti-inflammatory strategy is not adding specific "superfoods" but shifting the overall dietary pattern. Mediterranean-style eating patterns consistently demonstrate anti-inflammatory effects in clinical trials. Key components include colourful vegetables and fruits providing diverse polyphenols, fatty fish providing omega-3s, extra virgin olive oil rich in oleocanthal (a natural anti-inflammatory), nuts and seeds providing vitamin E and minerals, herbs and spices particularly turmeric and ginger, and fermented foods supporting gut barrier integrity.

Gut Barrier Function

The gut lining is a single-cell-thick barrier between the contents of your digestive system and your bloodstream. When this barrier is compromised, bacterial endotoxins (lipopolysaccharides) leak into the bloodstream, triggering systemic immune activation and inflammation.

Dietary factors that support gut barrier integrity include adequate fibre for short-chain fatty acid production, glutamine and zinc for enterocyte health, polyphenols from berries and green tea, and avoiding excessive alcohol which directly damages the gut lining.

Frequently Asked Questions

Can diet alone reduce chronic inflammation? Diet is the single most powerful modifiable factor for inflammation. Combined with adequate sleep, regular exercise, and stress management, dietary changes can reduce hs-CRP significantly within weeks to months.

Are anti-inflammatory supplements worth taking? Omega-3 supplementation and curcumin (with enhanced bioavailability formulations) have reasonable evidence for anti-inflammatory effects. These should complement, not replace, an anti-inflammatory dietary pattern.

How quickly can I see changes in inflammatory markers? Dietary changes can shift hs-CRP within 4 to 8 weeks. Omega-3 index improvements typically take 8 to 12 weeks of consistent supplementation.
