Anti-Inflammatory Foods: An Evidence-Ranked List (and Where Olive Oil Fits)
Anti-inflammatory foods are foods that, in human studies, are linked with lower levels of inflammatory markers in the blood, such as C-reactive protein (CRP), interleukin-6 (IL-6) and tumour necrosis factor-alpha (TNF-α). Most lists online simply name foods. This one ranks them by the quality of the human evidence: what meta-analyses of randomised controlled trials actually found when people ate or took them, with the numbers and the sources. Some popular "anti-inflammatory" foods come out well, some come out mixed, and a few hardly move the markers at all. We also explain where extra virgin olive oil fits, what the contested evidence on black seed oil says, and where the limits of food lie. If you have an inflammatory condition, this is background reading, not a treatment plan; talk to your doctor before changing your diet or adding supplements.
For the oil at the top of our list, see our Cold-Pressed Single-Estate Extra Virgin Olive Oil - Marrakech (500ml).
The Short Answer
- The foods with the most consistent human evidence of lower inflammatory markers are extra virgin olive oil, fruit and vegetables, and oily fish (mainly as omega-3 supplements), with curcumin, ginger and garlic close behind as concentrated supplements.
- A 2015 meta-analysis of 30 randomised trials with 3,106 people found that olive oil lowered CRP by 0.64 mg/L and also lowered IL-6 compared with control diets (Schwingshackl and colleagues, Nutrients).
- Several popular choices have weaker trial evidence than their reputation: nuts, whole grains, pulses and green tea showed no significant effect on CRP in their meta-analyses, and the evidence on coffee is observational.
- The evidence on black seed (Nigella sativa) is genuinely contested: some pooled analyses report lower CRP, while the largest, of 50 trials, found no significant effect.
- A lower CRP is a change in a blood marker, not proof that any disease is prevented or treated. No food replaces medical care for an inflammatory condition.
- Sidr & Stone's extra virgin olive oil is single-estate and cold-pressed, and our black seed oil is independently verified at 2.67% thymoquinone in its first batch (August 2025); neither is a medicine.
How We Ranked These Foods
We looked for the strongest human evidence available for each food: systematic reviews and meta-analyses that pooled randomised controlled trials and measured blood markers of inflammation. Each food was then placed in one of three tiers:
- Tier 1: pooled randomised trials show a significant fall in CRP and at least one other marker.
- Tier 2: some pooled analyses show a fall, but others disagree, the effect is small, or it disappears in better-designed trials.
- Tier 3: the main meta-analysis found no significant effect on CRP, or the only evidence is observational.
Three cautions apply throughout. First, CRP, IL-6 and TNF-α are markers of chronic, low-grade inflammation, not diseases; lowering a marker is not the same as preventing or treating anything. Second, several of the strongest results come from concentrated supplements (curcumin, ginger, garlic and fish-oil capsules), not from the amounts people use in cooking. Third, many of the underlying trials are small and short, and the pooled results vary a lot between studies. Every study we cite is listed with its PubMed ID at the end, and each was checked against the Europe PMC record.
Anti-Inflammatory Foods Ranked: The List at a Glance
Here is the ranking in one table. The "change" column shows the pooled difference against control groups; a negative number means lower levels of the marker.
| Food | Best human evidence | What happened to inflammatory markers | Tier |
|---|---|---|---|
| Extra virgin olive oil | Meta-analysis of 30 RCTs, 3,106 people (2015) | CRP −0.64 mg/L; IL-6 lower | 1 |
| Fruit and vegetables | Review of 83 studies, 71 of them trials (2018) | CRP and TNF-α lower | 1 |
| Oily fish / omega-3 | Meta-analysis of 68 RCTs, 4,601 people (2014) | Supplements lowered CRP, IL-6 and TNF-α; fish as food lowered IL-6 only | 1 (supplements) / 2 (food) |
| Turmeric (curcumin) | Umbrella review of 21 meta-analyses (2024) | CRP −0.87 mg/L; IL-6 and TNF-α lower | 1 (as supplements) |
| Ginger | Meta-analysis of 29 RCTs (2025) | CRP −0.86 mg/L; IL-6 and TNF-α lower | 1 (as supplements) |
| Garlic | Meta-analysis of 16 RCTs (2019) | CRP −0.61 mg/L; IL-6 and TNF-α lower | 1 (as supplements) |
| Black seed (Nigella sativa) | Several meta-analyses, which disagree | CRP lower in some; no significant effect in the largest (50 RCTs) | 2 |
| Berries (anthocyanins) | Meta-analysis of purified anthocyanin RCTs (2024) | CRP −0.12 mg/L; IL-6 and TNF-α lower | 2 |
| Dairy and yogurt | Meta-analysis of 11 RCTs, 663 people (2020) | CRP −0.24 mg/L, but no effect in crossover trials | 2 |
| Nuts | Meta-analysis of 32 RCTs (2017) | No significant change in CRP | 3 |
| Whole grains | Meta-analysis of 14 RCTs, 1,238 people (2020) | No significant change in CRP | 3 |
| Pulses (non-soy legumes) | Meta-analysis of RCTs (2024) | No significant change in CRP, IL-6 or TNF-α | 3 |
| Green tea | Meta-analysis of 38 RCTs (2025) | No significant change in CRP, IL-6 or TNF-α | 3 |
| Coffee | Meta-analysis of 11 cross-sectional studies, 66,691 people (2024) | Coffee drinkers had lower CRP; no trial evidence | 3 |
Tier 3 does not mean "bad for you". Nuts, whole grains, pulses and green tea have other well-studied benefits; the point is only that, measured by inflammatory markers in randomised trials, their effect has not been shown.
Tier 1: Foods With Consistent Reductions in Pooled Trials
Extra virgin olive oil
Olive oil has some of the clearest food-level evidence. Schwingshackl and colleagues pooled 30 randomised trials with 3,106 participants and found that olive oil interventions lowered CRP by 0.64 mg/L (15 trials) and IL-6 (7 trials) compared with control diets, and improved flow-mediated dilation, a measure of blood-vessel function (Nutrients, 2015). The type of oil matters: a 2026 meta-analysis of 23 trials found that extra virgin olive oil lowered CRP by 0.99 mg/L compared with olive oils low in phenolic compounds, although the authors rated the certainty of the evidence as moderate to very low (Vidal Damasceno and colleagues, Critical Reviews in Food Science and Nutrition).
Fruit and vegetables
Hosseini and colleagues reviewed 83 studies, 71 of them clinical trials, and their meta-analysis found that eating more fruit or vegetables lowered CRP and TNF-α (American Journal of Clinical Nutrition, 2018). This is less a single food than a whole category, which is part of why it works as everyday advice: leafy greens, tomatoes, peppers, onions, citrus and berries all count.
Oily fish and omega-3
In a meta-analysis of 68 trials with 4,601 people, marine omega-3 supplements lowered CRP, IL-6 and TNF-α, with larger effects in people without obesity and with longer use (Li and colleagues, PLoS One, 2014). When omega-3 came from food rather than capsules, which the review could only assess in people with chronic disease, IL-6 fell but CRP and TNF-α did not. Oily fish such as sardines, mackerel and salmon remain a sensible choice; the strongest marker evidence belongs to the supplements.
Turmeric (curcumin)
An umbrella review of 21 meta-analyses found that curcumin supplements lowered CRP by 0.87 mg/L, TNF-α by 2.72 pg/mL and IL-6 by 0.97 pg/mL (Kavyani and colleagues, Prostaglandins and Other Lipid Mediators, 2024). Note that these trials used concentrated curcumin, usually in capsules. Turmeric as a spice contains only a small fraction of curcumin, so a teaspoon in a curry is not the dose that was tested.
Ginger
A 2025 meta-analysis of 29 trials found that ginger supplements lowered CRP by 0.86 mg/L, TNF-α by 1.90 pg/mL and IL-6 by 1.15 pg/mL, with the clearest effects in people with existing health conditions (Rjabi and colleagues, Inflammopharmacology). The authors flagged high variation between studies and asked for the results to be read cautiously.
Garlic
Darooghegi Mofrad and colleagues pooled 16 trials, with garlic doses from 12 mg to 3,600 mg a day for 2 to 52 weeks, and found lower CRP (by 0.61 mg/L), IL-6 and TNF-α (Journal of Nutrition, 2019). Again, most of these trials used garlic supplements or extracts, and the results varied widely from study to study.
Tier 2: Mixed or Contested Evidence
Black seed (Nigella sativa)
Black seed sits in the middle because the meta-analyses disagree. An umbrella review of seven meta-analyses reported lower CRP and TNF-α with Nigella sativa supplements (Lan and Xia, Prostaglandins and Other Lipid Mediators, 2025), and a 2025 meta-analysis of 82 studies with 5,026 participants reported lower CRP, IL-6 and TNF-α among many other risk factors (Jafari and colleagues, Pharmacological Research). But the largest pooling of randomised trials, 50 of them, found no significant effect on CRP or TNF-α, while finding clear changes in blood lipids and glucose (Hallajzadeh and colleagues, Phytotherapy Research, 2020). The underlying trials are mostly small and short. Our article on black seed oil and inflammation sets out the disagreement in full, and our piece on black seed oil and joint pain covers the condition-specific trials.
Berries (anthocyanins)
Anthocyanins are the purple-red pigments in blueberries, blackcurrants, cherries and red cabbage. A meta-analysis of trials using purified anthocyanins found small falls in CRP (0.12 mg/L), TNF-α and IL-6, with the CRP effect mainly in people whose CRP was already raised (Hariri and colleagues, Phytotherapy Research, 2024). These were extracts, not bowls of berries, and the effect on CRP was small, which is why berries sit in tier 2 despite their reputation.
Dairy and yogurt
A meta-analysis of 11 trials with 663 adults found lower CRP, IL-6 and TNF-α with higher dairy intake, but no benefit when the analysis was limited to crossover trials, and effects that tended towards zero in the most consistent subgroups (Moosavian and colleagues, Nutrition, Metabolism and Cardiovascular Diseases, 2020). In other words, dairy and yogurt do not appear to raise inflammation, but the case that they lower it is weak.
Tier 3: Popular Foods With Little Effect on the Markers
- Nuts: in 32 randomised trials, nut consumption made no significant difference to CRP (−0.01 mg/L) or other inflammatory markers, although it did improve blood-vessel function (Neale and colleagues, BMJ Open, 2017).
- Whole grains: across 14 trials with 1,238 adults, whole grains did not significantly change CRP overall, though there were hints of benefit in people whose CRP was already high (Rahmani and colleagues, Advances in Nutrition, 2020).
- Pulses: beans, lentils and chickpeas did not significantly change CRP, IL-6 or TNF-α in a 2024 meta-analysis, although they raised adiponectin, a hormone made by fat tissue (Mansouri and colleagues, Journal of Nutritional Biochemistry).
- Green tea: in 38 trials, green tea improved markers of antioxidant status but did not change CRP, IL-6 or TNF-α (Dehzad and colleagues, Journal of Nutritional Science, 2025).
- Coffee: across 11 cross-sectional studies with 66,691 people, those who drank more coffee had lower CRP (Choi and Je, Nutrition, Metabolism and Cardiovascular Diseases, 2024). That is an association, not proof of cause, and there were no randomised trials in the analysis.
Nuts, whole grains and pulses are still central to the Mediterranean pattern and to most healthy-eating advice, for fibre, heart health and blood-sugar control. They simply have not shown a marker effect on their own in trials.
Where Olive Oil Fits
Olive oil is the one everyday cooking fat in this ranking with a meta-analysis of randomised trials showing lower CRP and IL-6, and extra virgin olive oil is the main fat of the Mediterranean eating pattern. That matters: unlike the curcumin or garlic results, which come mostly from extracts, this is evidence about something people actually eat. The 2026 comparison of extra virgin olive oil with low-phenolic olive oils also suggests that the minor compounds in good extra virgin oil, the polyphenols, are part of the story, not just the fat.
Two honest limits apply. The olive oil trials measured markers, not disease, and in many of them olive oil was part of a wider diet, so its effect cannot be fully separated from everything else on the plate. For the compounds involved and what the laboratory work shows, see our article on olive oil and inflammation. If you have read that other cooking oils are themselves inflammatory, our review of whether seed oils cause inflammation looks at the trials behind that claim. And for how these foods come together as a whole way of eating, see our guide to the anti-inflammatory diet.
If you buy olive oil for its polyphenols, choose extra virgin, look for a recent harvest date and a named origin, and store it away from heat and light. Our guide to choosing a quality olive oil explains what to check on the label.
Do Anti-Inflammatory Foods Work? The Honest Limits
They can shift blood markers, modestly, when eaten consistently. They are not a fast-acting fix, and the evidence has real limits that most lists leave out:
- Markers are not outcomes. A CRP that falls by half a milligram per litre is a measurable change; it is not evidence that a particular illness has been prevented or improved.
- Supplement doses are not kitchen doses. The curcumin, ginger, garlic and anthocyanin results come mostly from capsules and extracts.
- The trials are small and varied. High heterogeneity, short durations and different populations mean the pooled numbers are estimates, not guarantees.
- The overall pattern matters more than any single food. Weight, smoking, activity and sleep all affect these markers too.
Some readers come to this topic because of a specific problem, such as joint pain, a bowel condition or period pain. Food can sit alongside medical care, but it does not replace it. Period pain is one example: a 2024 meta-analysis of 12 trials found that ginger reduced the intensity of period pain compared with placebo, but the authors noted a risk of bias in the studies and that safety was rarely reported (Moshfeghinia and colleagues, Journal of Integrative and Complementary Medicine). If your periods are very painful, or the pain is new or getting worse, see your GP or gynaecologist. The same applies to any inflammatory condition: do not stop, delay or reduce prescribed treatment because of a diet change, and check with your doctor or pharmacist before taking concentrated supplements, particularly if you take blood thinners, diabetes or blood-pressure medication, or are pregnant.
Why Sidr & Stone
Two of the foods in this ranking are ones we make. We will not tell you either of them lowers inflammation on its own; that is the kind of claim this article warns against. What we can give you is facts you can check about what is in the bottle.
- Sidr & Stone's extra virgin olive oil is single-estate, from our own family-owned farm on the plains outside Marrakech, Morocco, where we control every step from tree to bottle.
- It is rain-fed and organically grown, with no synthetic fertilisers, pesticides or herbicides (not yet certified; certification is in progress).
- It is cold-pressed and left unfiltered, from a limited single-harvest batch, in 500ml dark glass.
- Sidr & Stone's black seed oil is independently verified at 2.67% thymoquinone in its first batch (August 2025) by Analytice, an ISO 9001-certified French analytical testing service.
- It is pressed from organically grown Ethiopian highland Nigella sativa, chosen after a 36-supplier evaluation, and cold-pressed below 40°C.
- It is unrefined, 100% pure Nigella sativa oil, bottled in 100ml matte black UV-protective glass.
- 10% of profits go to charity, with fulfilment in the UK, EU, and US.
We will not claim our oils are the best or the most anti-inflammatory. What we will say is that the olive oil comes from one estate we run ourselves, and the black seed oil carries a published, independently verified figure you can read for yourself.
Frequently Asked Questions
What are the most anti-inflammatory foods?
Judged by randomised trials, the most consistent results are for extra virgin olive oil, fruit and vegetables, and omega-3 from oily fish, with curcumin, ginger and garlic supplements also lowering CRP in pooled trials. Nuts, whole grains, pulses and green tea showed little effect on the markers.
Do anti-inflammatory foods actually work?
They can lower blood markers such as CRP modestly when eaten consistently, and several analyses found clearer effects in people whose markers were already raised. They do not cure or treat inflammatory diseases, and the effect of a whole eating pattern is larger than that of any single food.
Is turmeric in food the same as curcumin supplements?
No. The trials behind turmeric's ranking used concentrated curcumin, mostly in capsules. Turmeric powder contains only a small proportion of curcumin, so cooking with it is not the same dose. Check with a pharmacist before taking curcumin if you use other medicines.
Are there anti-inflammatory foods for period cramps?
Ginger has the most research: a meta-analysis of 12 trials found less intense period pain than with placebo, though the studies had a risk of bias. Severe, new or worsening period pain should be checked by a GP.
Is coffee anti-inflammatory?
Coffee drinkers tend to have lower CRP in observational studies of more than 66,000 people, but there are no randomised trials showing coffee lowers it. Treat it as an association, not a proven effect.
Is Sidr & Stone's olive oil or black seed oil anti-inflammatory?
We do not make that claim. Olive oil has meta-analysis evidence for lower CRP and IL-6, and black seed's evidence is contested. Our oils are foods: a single-estate extra virgin olive oil and a black seed oil verified at 2.67% thymoquinone in its first batch (August 2025).
Where can I buy single-estate extra virgin olive oil and black seed oil?
Both are sold directly from sidrstone.com, with fulfilment in the UK, EU, and US. Our olive oil is available to pre-order as a limited single-harvest batch, and our black seed oil is available now.
Is olive oil a medicine?
No. Olive oil is a food, not a medicine. It has a long traditional history — including being honoured in the Prophetic Sunnah — and a substantial body of modern research, particularly around polyphenols, cardiovascular health, and the Mediterranean diet pattern. It can be a worthwhile part of a healthy routine, but it does not cure diseases and is not a substitute for medical care. Be cautious of any olive oil marketed with specific disease-cure claims.
Final Thoughts
Ranked by the human evidence, the anti-inflammatory foods worth building around are unglamorous: extra virgin olive oil, plenty of fruit and vegetables, and oily fish. Spices such as turmeric, ginger and garlic have promising results, mostly as concentrated supplements. Several foods with big reputations, from nuts to green tea, are good for other reasons but have not moved inflammatory markers in trials. And black seed, which we sell, has evidence that genuinely points both ways.
The bigger lesson is proportion. Food can shift a blood marker; it does not replace a diagnosis or a treatment. If you have an inflammatory condition, keep your doctor in the loop and change your diet alongside your care, not instead of it.
If you are starting with the oil, our Cold-Pressed Single-Estate Extra Virgin Olive Oil - Marrakech (500ml) is available to pre-order as a limited single-harvest batch, and our Cold-Pressed Ethiopian Black Seed Oil (100ml), independently tested (first batch: 2.67% thymoquinone, Analytice, Aug 2025), is available now, both with fulfilment in the UK, EU, and US.
Our extra virgin olive oil is grown organically on our own single-estate farm on the plains outside Marrakech: we control every step from tree to bottle, and no synthetic pesticides, herbicides or fertilisers are used. It is not yet certified organic — certification is in progress, and we will publish it as soon as it comes through.
Our black seed oil is pressed from organically grown Ethiopian highland Nigella sativa, but it is not certified organic: formal organic certification is hard to obtain in the Ethiopian highlands, so we tell you how the seed is grown rather than claim a certificate we do not hold.
