Chronic Inflammation Test — DII Calculator

Guide: how your inflammation score is calculated

Low-grade chronic inflammation is a silent risk factor linked to heart disease, type 2 diabetes, cancer, and Alzheimer’s. This calculator evaluates 7 dimensions of your lifestyle to estimate your overall inflammatory risk through a weighted average.

Methodology

Our calculator is based on the Dietary Inflammatory Index (DII) by Shivappa et al. (2014) and the Dietary Inflammatory Score (DIS) by Byrd et al. (2019), extended with lifestyle factors documented by Furman et al. (2019). Each dimension receives a score from 0 to 100 and is combined with evidence-based weights.

The 7 dimensions and their weights

• Diet (30%): Intake of fruits, vegetables, fish, whole grains, processed foods, and sugar.
• Physical activity (15%): Weekly exercise frequency, duration, and intensity.
• Body composition (15%): BMI and waist circumference as indicators of visceral fat.
• Sleep (10%): Duration and quality of nighttime sleep.
• Stress (10%): Perceived stress level and management practices.
• Substances (15%): Tobacco and alcohol consumption.
• Hydration (5%): Daily water intake.

Score interpretation

The overall score ranges from 0 to 100. A score of 75-100 indicates low inflammatory risk (your habits are anti-inflammatory). 50-74 indicates moderate risk (there is room for improvement). 25-49 indicates high risk (multiple factors are promoting inflammation). 0-24 indicates very high risk (consulting a healthcare professional is recommended). Each dimension also receives its own score, allowing you to identify the specific areas that contribute most to your inflammatory risk.
