'Anti-inflammatory diet' has become a wellness catch-all sold to fix everything from joint pain to weight loss to autoimmune disease. The underlying science exists but is narrower than the marketing implies — chronic low-grade inflammation responds to a specific set of dietary patterns, and most of the rest is marketing.
What chronic inflammation actually is
Persistent low-level activation of immune system signalling, measurable through markers like CRP and IL-6. Linked to cardiovascular disease, insulin resistance, autoimmune conditions, and possibly some cancers. Distinct from acute inflammation (the helpful response to injury or infection).
Diet is one of several factors. Sleep, stress, exercise, smoking, and body composition all matter as much or more than diet for chronic inflammation.
Dietary patterns with the best evidence
Mediterranean diet
Olive oil, fish, vegetables, whole grains, nuts, moderate wine. Lowest CRP levels in multiple meta-analyses. The single most-evidence-backed anti-inflammatory pattern.
Higher omega-3 intake
Oily fish 2x weekly, or 1-2g EPA+DHA supplement. Genuinely lowers inflammatory markers in deficient people.
Adequate polyphenols
Colorful fruit and vegetables, herbs, dark chocolate, green tea. Antioxidant effects measurable but modest.
Limiting ultra-processed foods
Stronger association with inflammation than individual ingredients. Reducing UPF intake is one of the highest-leverage dietary changes.
What's mostly marketing
Specific 'anti-inflammatory' foods marketed in isolation (turmeric pills, golden milk, etc.) — small effects compared to overall dietary pattern. Elimination diets (gluten-free, dairy-free for non-allergic people) — minimal benefit for general inflammation; potentially harmful by removing nutrient sources. Expensive 'anti-inflammatory' supplements with limited evidence — money usually better spent on actual food.
Where to start, realistically
Mediterranean-pattern eating most days. Oily fish 2x weekly. Vegetables 5+ servings daily. Olive oil as primary cooking fat. Reduce ultra-processed foods by 50%+ from baseline. This handles 80% of dietary anti-inflammatory potential without obsession.
Anti-inflammatory eating is real and worth doing. It's also boring and well-known — Mediterranean diet, more fish, less processed food. The buzzword industry has dressed up basic nutrition advice in expensive packaging.
