Qu'est-ce que Mediterranean Diet Score?
▾
The Mediterranean diet is consistently ranked as one of the world's healthiest dietary patterns, characterized by high consumption of fruits, vegetables, whole grains, legumes, nuts, olive oil (the primary fat), and moderate fish consumption, with limited red meat, processed foods, and sweets. Named after the traditional eating habits of populations bordering the Mediterranean Sea, this pattern was first studied by Ancel Keys in the Seven Countries Study beginning in the 1950s. The landmark PREDIMED trial (2013), a randomized controlled trial of 7,447 high-cardiovascular-risk adults in Spain, found that Mediterranean diet adherence with extra-virgin olive oil or nuts reduced major cardiovascular events by 30% compared to a low-fat control diet. The Mediterranean diet also shows protective associations with type 2 diabetes, Alzheimer's disease, depression, and all-cause mortality in multiple large cohort studies. The Mediterranean Diet Adherence Score (MEDAS) is a validated 14-point questionnaire used in the PREDIMED trial to quantify dietary adherence. Each point represents a dietary behavior; scores ≥10 indicate high adherence. The calculator here assesses intake frequencies across the core food categories and generates a composite adherence score with personalized improvement recommendations.

High adherence; protective against cardiovascular events per PREDIMED.
Moderate; focus on increasing vegetables, fish, and legumes.
High risk; significant dietary overhaul recommended.
Simple swaps over 4 weeks raise score from low to moderate adherence.
Applications pratiques
▾
Professionals in health and medical use Mediterranean Score as part of their standard analytical workflow to verify calculations, reduce arithmetic errors, and produce consistent results that can be documented, audited, and shared with colleagues, clients, or regulatory bodies for compliance purposes.
University professors and instructors incorporate Mediterranean Score into course materials, homework assignments, and exam preparation resources, allowing students to check manual calculations, build intuition about input-output relationships, and focus on conceptual understanding rather than arithmetic.
Consultants and advisors use Mediterranean Score to quickly model different scenarios during client meetings, enabling real-time exploration of what-if questions that would otherwise require returning to the office for detailed spreadsheet-based analysis and reporting.
Individual users rely on Mediterranean Score for personal planning decisions — comparing options, verifying quotes received from service providers, checking third-party calculations, and building confidence that the numbers behind an important decision have been computed correctly and consistently.

What is a Mediterranean Diet Score?
The Mediterranean Diet Score measures adherence to the traditional Mediterranean dietary pattern on a 0-14 point scale. You get 1 point for each: high intake of vegetables (≥4 servings/day), fruits (≥3), legumes (≥3/week), whole grains (≥3/day), fish (≥3/week), nuts (≥3/week), olive oil as primary fat, and moderate red wine (1 glass/day for women, 1-2 for men). You get 0 points for high intake of: red meat, processed meat, butter/cream, sugar/sweets, and full-fat dairy. Scores of 9-14 indicate good adherence and are associated with the most significant health benefits. The PREDIMED study showed that high adherence reduced cardiovascular events by 30%.
What are the proven health benefits of the Mediterranean diet?
The Mediterranean diet has the strongest evidence base of any dietary pattern. Proven benefits: 30% reduction in major cardiovascular events (heart attack, stroke, cardiovascular death) in the landmark PREDIMED trial, 25-35% reduced risk of type 2 diabetes, significant reduction in cognitive decline and dementia risk, reduced inflammation markers (CRP, IL-6), improved cholesterol profile (raises HDL, lowers triglycerides), modest weight loss and waist circumference reduction, and reduced risk of certain cancers (breast, colorectal). The key components driving benefits appear to be: extra virgin olive oil (polyphenols and healthy fats), fish (omega-3 fatty acids), nuts, and the overall anti-inflammatory pattern of high vegetables, fruits, and whole grains with minimal processed food.
How is the Mediterranean Diet Score calculated?
The Mediterranean Diet Score is typically calculated based on a 14-point scale, where participants receive 1 point for each of 14 food groups they consume, including fruits, vegetables, whole grains, and nuts. For example, if a person consumes 5 servings of fruits and vegetables per day, they may receive 1 point for meeting the fruit and vegetable criteria. The score is then calculated by adding up the points for each food group. A higher score indicates greater adherence to the Mediterranean diet, with a maximum score of 14.
What are some common foods that can help increase my Mediterranean Diet Score?
Some common foods that can help increase your Mediterranean Diet Score include fatty fish such as salmon, which is rich in omega-3 fatty acids, as well as olive oil, which is high in monounsaturated fats. Legumes, such as lentils and chickpeas, are also rich in fiber and protein and can contribute to a higher score. Aim to consume at least 2 servings of fatty fish per week and 1 tablespoon of olive oil per day to help boost your score.
Are there any specific nutrient targets I should aim for to achieve a high Mediterranean Diet Score?
To achieve a high Mediterranean Diet Score, aim to consume at least 5 servings of fruits and vegetables per day, with a goal of 400g per day. Additionally, aim to consume 3 servings of whole grains per day, such as brown rice, quinoa, and whole wheat bread. It is also recommended to limit red meat consumption to no more than 2 servings per week and to consume no more than 25g of sugar per day.
Erreurs courantes à éviter
▾
- !Adding olive oil to an otherwise unhealthy diet without changing overall eating pattern.
- !Over-consuming alcohol thinking it is required for Mediterranean health benefits.
- !Using refined olive oil (not extra-virgin)—polyphenol content is dramatically lower.
- !Ignoring portion control—Mediterranean eating is portion-moderate, not unlimited.
- !Treating pasta as the centerpiece rather than an occasional component alongside vegetables.
- !Neglecting legumes, which are underused in modern Mediterranean-inspired diets.
Conseil Pro
The highest-leverage single change: replace all cooking fats (butter, vegetable oil, lard) with extra-virgin olive oil and use it generously in salad dressings. This alone improves MEDAS score and shifts fat quality dramatically.
Le saviez-vous?
Populations in the original Seven Countries Study in Crete in the 1960s consumed up to 40% of calories from fat—nearly all from olive oil—yet had the lowest cardiovascular disease rates of any population studied.
