The phrase 'anti-inflammatory diet' has been so heavily marketed that it's almost lost its shape. Strip away the marketing and the underlying claim is straightforward: chronic, low-grade inflammation is implicated in cardiovascular disease, type 2 diabetes, neurodegenerative disease, and most of the conditions that shorten healthy lifespan. What you eat moves that inflammation up or down. The shifts are small per meal but accumulate.
The strongest evidence sits behind a small group of foods. Olive oil — the real kind, with measurable polyphenols — reduces inflammatory markers in well-designed trials. Fatty fish twice a week moves omega-3 to omega-6 ratios in the right direction. Leafy greens, berries, nuts, legumes, and cruciferous vegetables all show up consistently in the literature. Dark chocolate and coffee, perhaps surprisingly, sit on the same side of the ledger.
On the other side: sugar-sweetened drinks, ultra-processed foods, industrial trans fats (mostly gone from supermarkets but still lurking in some baked goods), high-temperature charred meats, and excessive alcohol. Notice the pattern. The harmful list is mostly stuff that is engineered, not grown. The helpful list is mostly stuff that is grown, not engineered.
The practical question is what you actually cook. A useful frame: build dinner around a vegetable, a legume or fish, a whole grain, and olive oil. That single template covers a Niçoise salad, a chickpea stew, grilled sardines with tabbouleh, lentil soup with crusty bread. None of it requires special ingredients or aspirational cookware.
What about supplements? Fish oil, curcumin, vitamin D — these all move the same biomarkers, but the effect sizes are smaller than the effect of just eating a Mediterranean-pattern diet. If your diet is already in the right shape, supplements may add a little. If your diet isn't, supplements won't compensate for it.
The other axis worth thinking about is consistency versus intensity. A perfect meal three times a year does almost nothing. A pretty good meal four nights a week does most of the work. The goal is not to optimize any single dinner. The goal is to make the average dinner unobjectionable, and to keep doing that for years.
“Chronic inflammation is the slow background music of most modern disease. Quieting it is mostly a matter of what you put on the plate, not what you take out of it.”
