Mediterranean-style eating has clearer guideline support and a more established record of research on cardiovascular outcomes. But it has not been shown in a direct head-to-head trial to outperform every diet called “anti-inflammatory.” The labels overlap: both can mean eating more vegetables, fruit, legumes, nuts, whole grains, fish, and unsaturated fats, and less highly processed food and added sugar. For heart health, focus on a sustainable, high-quality eating pattern rather than treating a diet label, single food, or supplement as a cure.
Why the labels are not a like-for-like comparison
Mediterranean-style eating is a named pattern
There is no single standard Mediterranean diet. Food traditions vary across Mediterranean countries and regions. A typical version emphasizes fruits, vegetables, grains, potatoes, beans, nuts, and seeds, with olive oil as a primary fat. Dairy, eggs, fish, and poultry are generally eaten in low-to-moderate amounts; fish and poultry are more common than red meat. The pattern centers on minimally processed plant foods. The American Heart Association’s overview describes these features and notes that overall diet quality matters more than any single nutrient or food.
“Anti-inflammatory diet” is an umbrella term
The phrase does not refer to one uniform prescription. A 2025 systematic review included a range of patterns and approaches, such as Mediterranean, DASH, vegan, Nordic, ketogenic, vegetarian, plant-based, and dietary inflammatory index interventions. So when a source recommends an “anti-inflammatory diet,” check which foods, scoring system, or specific pattern it actually means. Evidence that an intervention changes inflammatory markers is not, by itself, proof that it prevents heart attacks or strokes. The 2025 review’s abstract addresses anti-inflammatory diets and cardiovascular risk factors.

Mediterranean-style diets have a substantial, but qualified, event evidence base
A 2019 Cochrane review assessed 30 randomized controlled trials, reported across 49 papers, involving 12,461 participants. In its account of PREDIMED, stroke occurrence fell from 24 per 1,000 participants to 14 per 1,000 in the Mediterranean-diet comparison. The review found little or no effect on cardiovascular or total mortality compared with a low-fat diet, and it noted that PREDIMED had been retracted and re-analyzed after randomization concerns at two of its 11 sites. Cochrane rated some event evidence low to moderate quality and said uncertainty remained. These results describe a study comparison, not a guaranteed benefit for an individual. Read the Cochrane review.
#1 Best Overall
The 2019 ACC/AHA primary-prevention guideline summarizes PREDIMED differently by highlighting its combined endpoint: it reports reductions of 30% in the extra-virgin olive-oil arm and 28% in the nut arm. The guideline says the result was largely driven by stroke, with no significant improvement over control for mortality or myocardial infarction. Those figures refer to that guideline’s summary of a particular endpoint; they should not be generalized as a 30% reduction in all heart events. See the 2019 ACC/AHA guideline.
Evidence for the broad anti-inflammatory label is harder to compare
The 2025 review examines multiple diets and cardiovascular risk factors, but the evidence summarized here does not establish through a direct head-to-head cardiovascular-event trial that a distinct “anti-inflammatory diet” outperforms Mediterranean-style eating. That comparison gap does not mean anti-inflammatory dietary features are harmful; it means the broad label cannot be treated as one tested competitor with a single outcome record.
Guidance emphasizes the overall pattern
The AHA’s 2026 dietary guidance updates its 2021 statement and presents food-based guidance for cardiovascular health across the life course. Its practical focus is a heart-healthy eating pattern rather than a contest between diet names. The 2023 chronic coronary disease guideline describes Mediterranean-type plans that include more healthy plant foods and lean protein such as fish, and less saturated fat, as helping reduce risk factors including dyslipidemia and hypertension. It also says more research is needed on mechanisms and cardiovascular and all-cause death. Read the AHA’s 2026 dietary guidance; see the 2023 chronic coronary disease guideline.

How to choose an approach that works for you
Compare the actual eating pattern—not just the name—on these points:
- What it asks you to eat: Look for a practical emphasis on vegetables, fruit, whole grains, beans and other legumes, nuts, fish, and unsaturated fats. An “anti-inflammatory” plan should specify its foods or method rather than rely on the label.
- What evidence it cites: Separate changes in inflammatory markers or risk factors from evidence about events such as stroke, heart attack, or cardiovascular death. Note who was studied and whether the question was primary prevention or care for established coronary disease.
- Whether you can sustain it: Choose a pattern that fits your food preferences, culture, budget, and routine. Consistency and overall quality matter more than adopting a particular label.
The AHA’s heart-healthy pattern emphasizes vegetables, fruits, whole grains, beans and legumes, and nuts; it also includes fish, poultry, low-fat or fat-free dairy, and non-tropical vegetable oils. It recommends limiting added sugars, sugary drinks, sodium, highly processed foods, refined carbohydrates, saturated fats, and fatty or processed meats. Mediterranean-style eating can fit this wider framework, while the precise foods in a plan marketed as anti-inflammatory need to be assessed individually.

Extra-virgin olive oil can be a cooking ingredient in a Mediterranean-style pattern, but the PREDIMED results do not show that oil alone creates the trial outcome. The same caution applies to individual foods, inflammation scores, and supplements: the evidence here does not justify promises that any one of them will prevent cardiovascular disease.

If you have diagnosed cardiovascular disease, kidney disease, medication-related food restrictions, or another clinical nutrition need, discuss major diet changes with your clinician or a registered dietitian. Do not use diet in place of prescribed treatment.
