Calculate your Dietary Inflammatory Index (DII) score based on daily food intake. Assess whether your diet promotes or reduces chronic inflammation.
Dietary patterns are often discussed in relation to inflammation markers and broader health outcomes. This worksheet turns a selected set of food categories into a directional score so you can compare one day or pattern with another.
The Dietary Inflammatory Index (DII) is a research-based scoring framework. This page uses a simplified version of that idea so you can get a practical score and compare patterns without treating the result as a laboratory measurement.
Use the result as a planning reference for adjusting food choices, not as a medical diagnosis.
This calculator turns common food choices into a simplified score so you can compare patterns over time and see which categories push the worksheet score up or down.
Simplified DII Score = ∑(Anti-inflammatory food scores) – ∑(Pro-inflammatory food scores) Each food category is weighted by its inflammatory impact coefficient from the original DII research. Anti-inflammatory foods contribute negative (anti-inflammatory) points. Pro-inflammatory foods contribute positive (inflammatory) points. Score interpretation: • ≤ −3: Strongly anti-inflammatory • −3 to −1: Moderately anti-inflammatory • −1 to +1: Neutral • +1 to +3: Moderately pro-inflammatory • > +3: Strongly pro-inflammatory
Result: DII Score: −1.4 (Moderately Anti-inflammatory)
Vegetables (3 servings × −0.25 = −0.75), fruits (2 × −0.30 = −0.60), fish (0.5 × −0.50 = −0.25), whole grains (2 × −0.20 = −0.40) = −2.0 anti-inflammatory. Processed meat (0.5 × +0.30 = +0.15), refined sugar (2 × +0.25 = +0.50) = +0.65 pro-inflammatory. Net DII: −2.0 + 0.65 = −1.35 ≈ −1.4. A good score that could improve by reducing sugar and increasing fish.
Chronic low-grade inflammation is measured by blood markers like C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor alpha (TNF-α). Elevated levels of these markers are associated with cardiovascular disease, insulin resistance, and accelerated aging. Diet is one of the most modifiable risk factors for chronic inflammation.
The most evidence-backed anti-inflammatory foods include: fatty fish (EPA and DHA omega-3s), extra-virgin olive oil (oleocanthal, a natural COX-2 inhibitor), turmeric (curcumin), ginger (gingerols), berries (anthocyanins), dark leafy greens (nitrates and polyphenols), nuts especially walnuts (ALA omega-3), and dark chocolate (flavanols). Regular consumption of these foods consistently lowers inflammatory markers.
The practical approach: fill half your plate with colorful vegetables and fruits, choose fish 2–3 times per week, use olive oil as your primary cooking fat, include nuts and seeds daily, flavor with spices instead of sugar or excess salt, and limit processed foods, refined grains, and added sugars. This pattern naturally achieves a low DII score without strict rules or elimination.

This worksheet applies fixed positive and negative weights to selected food groups to produce a directional inflammation score. It is a simplified planning score, not a clinical diagnosis or a direct measurement of inflammatory markers.
The DII is a literature-based scoring system created by researchers at the University of South Carolina. It assigns inflammatory effect scores to 45 food parameters based on nearly 2,000 peer-reviewed studies. A higher score means a more pro-inflammatory diet (linked to higher disease risk), while a lower/negative score means a more anti-inflammatory diet.
Certain foods trigger inflammatory pathways: refined sugars spike blood glucose and promote AGE (advanced glycation end product) formation. Omega-6 fatty acids (in processed oils) are converted to pro-inflammatory eicosanoids. Trans fats directly activate inflammatory gene expression. Conversely, omega-3 fats produce anti-inflammatory resolvins, and polyphenols in fruits and vegetables inhibit NF-kB (a master inflammatory switch).
This is a simplified version focused on the most impactful food categories. The full DII scores 45 dietary parameters including specific fatty acids, vitamins, minerals, and phytochemicals. This calculator captures the major drivers of dietary inflammation, making it practical for everyday use while maintaining directional accuracy.
Research links high DII scores to increased risk of cardiovascular disease, type 2 diabetes, colorectal cancer, depression, Alzheimer's disease, and all-cause mortality. A meta-analysis of 12 studies found that the most pro-inflammatory diets were associated with a 36% higher risk of cardiovascular disease and a 23% higher risk of cancer.
Absolutely. Fatty fish (salmon, sardines, mackerel) is one of the most powerful anti-inflammatory foods. Eggs, poultry, and lean meats are largely neutral. The key is to increase anti-inflammatory foods (fish, vegetables, olive oil, nuts, berries) while reducing pro-inflammatory ones (processed meat, refined sugar, fried foods). You don't need to eliminate any food group.
Blood markers of inflammation (CRP, IL-6) can improve within 2–4 weeks of dietary changes. Measurable health improvements typically appear within 4–8 weeks. The Mediterranean diet, which scores very low on the DII, has shown significant CRP reduction in as little as 3 weeks in clinical trials.
