Use the Dietary Inflammatory Index concept for a quick self-audit
Rate your diet’s inflammatory load using a simple pro- vs anti-inflammatory food ledger.
Why it works
The Dietary Inflammatory Index (DII) assigns pro-inflammatory (+) and anti-inflammatory (−) scores to food components based on their effects on CRP, IL-6, TNF-alpha, and other markers. The DII was developed by Shivappa et al. and validated against inflammatory biomarkers in multiple populations. You do not need to calculate a precise score — the concept makes the dietary ledger tangible: every food choice moves the needle toward or away from inflammation.
How to do it
- List your top 10 most-eaten foods and classify each as broadly pro-inflammatory (processed foods, seed oils, sugar, refined carbs) or anti-inflammatory (vegetables, fatty fish, olive oil, legumes, berries).
- Count items in each column — a quick ratio gives you a rough inflammatory load.
- Focus on shifting two or three items from the pro-inflammatory list, not eliminating everything at once.
- Repeat the audit monthly to track whether your ratio is improving.
Evidence
The DII is validated against inflammatory biomarkers in cross-sectional and cohort studies. Higher DII scores correlate with higher CRP and IL-6 in multiple populations. (observational)
DII is an epidemiological research tool; the simplified self-audit version captures the concept without the precision of the validated instrument.

Common mistake
Treating individual superfoods (turmeric, blueberries) as anti-inflammatory interventions while missing the baseline inflammatory pattern from the rest of the diet — superfoods don’t outweigh a pro-inflammatory background.

More practices for Anti-Inflammatory Diet for Mood, Made Practical
- Increase vegetable variety, not just volume
Eating 5–10 different vegetables per week is more anti-inflammatory than eating large amounts of two or three.
- Reduce ultra-processed foods as the highest-priority dietary change
Ultra-processed foods are the single largest driver of pro-inflammatory dietary patterns in most Western diets.
- Shift toward a Mediterranean dietary pattern
The Mediterranean pattern is the best-studied anti-inflammatory dietary template for both physical and mental health.
- Use extra-virgin olive oil as your primary fat
Extra-virgin olive oil is the most evidence-backed single food for anti-inflammatory effects.
- Reduce added sugar as an inflammation driver
Added sugar raises CRP and other inflammatory markers through multiple pathways — it is not just a calorie problem.
- Use herbs and spices liberally as low-calorie polyphenol sources
Herbs and spices have among the highest polyphenol density of any food — gram for gram, more than berries or vegetables.
