Acute inflammation is the body's defensive response to infections and trauma: red, hot, painful, necessary. It lasts days, then subsides. Low-grade chronic inflammation is completely different: silent, persistent, with few obvious symptoms, yet continuously active in damaging tissues. It's associated as a causal or amplifying factor in cardiovascular disease, type 2 diabetes, Alzheimer's, cancer, arthritis, depression, and obesity. And diet is one of its primary daily modulators.

How to measure chronic inflammation

The main markers of systemic inflammation measurable in blood: High-sensitivity CRP (hs-CRP): the most clinically used. Values below 1 mg/l indicate low inflammatory risk. Between 1 and 3 mg/l is moderate risk. Above 3 mg/l is high risk. hs-CRP isn't always included in routine tests: ask your doctor explicitly. IL-6 (interleukin-6): pro-inflammatory cytokine, more sensitive marker than CRP for acute variations. Fibrinogen: pro-coagulant protein elevated in inflammation. High ferritin: can indicate inflammation (beyond iron deficiency, whose test should be read in context). Omega-6/omega-3 ratio: not a direct inflammation marker, but reflects the substrate for inflammatory mediators.

Pro-inflammatory foods: what extinguishes health

Refined sugars and ultra-processed products: the primary dietary driver of chronic inflammation in developed countries. Excess glucose directly activates NF-κB (the "master regulator" of inflammation). Free fructose increases uricemia (uric acid is pro-inflammatory). Vegetable oils rich in omega-6 (soy, corn, standard sunflower): the imbalanced omega-6/omega-3 ratio (15:1 in Western diet vs. 4:1 optimal) shifts the balance toward pro-inflammatory eicosanoid production. Industrial trans fats: increase CRP and IL-6 in a dose-dependent manner. Now nearly eliminated in Europe by law. Excess alcohol: increases intestinal permeability, promotes passage of LPS (bacterial lipopolysaccharide endotoxin) into the bloodstream: a potent inflammatory trigger. Processed meats (cured meats, cold cuts, hot dogs): nitrites, heterocyclic amines, heavy metals: multiple inflammatory contributions.

Anti-inflammatory foods: the strongest evidence

Extra virgin olive oil: oleocanthal inhibits COX-1 and COX-2 (the same enzymes as ibuprofen). A 50 ml serving of quality EVOO contains the analgesic dose equivalent to about a quarter of an ibuprofen tablet. Cumulatively, over a lifetime of daily consumption, the anti-inflammatory effect is profound. Fatty fish (omega-3 EPA and DHA): convert into resolvins and protectins, lipid mediators that actively "resolve" inflammation rather than simply inhibit it. Meta-analyses of dozens of controlled studies confirm CRP, IL-6, TNF-alpha reduction with omega-3 supplementation. Turmeric (curcumin): inhibits NF-κB, reduces IL-1β, IL-6, TNF-alpha. Bioavailability increased by black pepper's piperine and fats. Clinical studies on rheumatoid arthritis, inflammatory bowel diseases, metabolic syndrome show documented anti-inflammatory effects. Berries (anthocyanins): potent NF-κB inhibitors. Meta-analyses show CRP and IL-6 reduction with regular consumption. Green tea (EGCG): inhibitor of MAPK (another inflammatory pathway) and NF-κB. Garlic: allicin and organosulfur compounds inhibit pro-inflammatory cytokine production. Cruciferous vegetables (sulforaphane): activator of Nrf2 (the primary regulator of endogenous antioxidant defenses).

The Dietary Inflammatory Index (DII): measuring your diet

The Dietary Inflammatory Index (DII) is a scientific tool developed by Shivappa et al. (2014) that assigns each food an inflammatory score based on scientific literature. Foods with strongly anti-inflammatory scores: turmeric, ginger, green tea, fatty fish, beta-carotene, vitamin C, vitamin E, magnesium, omega-3. Pro-inflammatory foods: excess total energy, total carbohydrates, saturated fats, cholesterol. Those with a low DII (predominantly anti-inflammatory diet) have significantly lower CRP, reduced cardiovascular risk, less cancer and chronic disease. Tools to calculate your DII are available online.

Measure your inflammation with hs-CRP

High-sensitivity CRP (hs-CRP) is an inexpensive blood test (just a few euros) that measures your current inflammatory level. Have it done the next time you get blood work. Then apply the anti-inflammatory diet described above for 8-12 weeks (EVOO, fatty fish, turmeric, berries, vegetables, less refined sugar) and retest. Most people with elevated hs-CRP see significant reductions in this timeframe. The objective data is the most powerful motivational reinforcement that exists.

The daily anti-inflammatory recipe

Golden milk: heat 200 ml of plant-based milk, add 1 teaspoon of turmeric, 1/4 teaspoon of black pepper, 1/2 teaspoon of ground ginger, 1 teaspoon of coconut oil or EVOO. Sweeten with honey if you like. This drink combines curcumin (anti-NF-κB), piperine (bioavailability +2000%), ginger (anti-COX), and fats (solubilize fat-soluble curcumin). Take daily, preferably in the evening. It's not acute medicine: it's a cumulative anti-inflammatory practice that delivers results in weeks.

How to reduce inflammation in seven days

Day 1: eliminate sugary drinks (cola, juices, energy drinks). Day 2: add turmeric + black pepper to at least one meal. Day 3: fatty fish (sardines or mackerel) for lunch or dinner. Day 4: 30g of nuts as a snack. Day 5: green tea instead of one coffee. Day 6: abundant salad with arugula, tomatoes, EVOO. Day 7: berries (blueberries, strawberries) as dessert or snack. It's not a radical diet: it's adding seven anti-inflammatory habits in seven days. Keep all seven for 8 weeks: your CRP drops, your health improves.
