Your score
Answer all 14 questions to see a score.
This page reproduces a published questionnaire and its arithmetic. It does not assess your diet or your health, does not tell you whether to change what you eat, and is not medical or dietary advice. Sam is a wellness companion, not a medical device. Discuss what the number means with a qualified healthcare professional.
How the score is calculated
Each of the 14 items is worth one point when your answer meets the criterion published with the instrument, and nothing otherwise. There is no weighting and no reverse scoring, so the total runs from 0 to 14. The 0-5, 6-9 and 10-14 grouping shown with your result is a convention used across the later literature rather than part of the instrument itself; the original publication defines no adherence categories.
Instrument and scoring: Schroeder et al., J Nutr 2011, with the full item table also reproduced in Martinez-Gonzalez et al., PLoS One 2012, both open access under CC BY. The German wording follows the validated German MEDAS used in the LIBRE study (Hebestreit et al., BMC Cancer 2017), adapted to informal address without changing any criterion.
Questions about MEDAS-14
What is MEDAS-14?+
A 14-item screener developed for the PREDIMED trial in Spain to measure how closely someone's eating pattern matches a Mediterranean one. Twelve items ask about food frequency and two about habits, and each is worth a single point.
Why does wine score a point?+
The instrument was developed and validated in a Spanish cohort where moderate wine with meals is part of the dietary pattern being measured, so the published item awards a point at seven or more glasses a week. It is reproduced here unchanged because changing an item would stop this being MEDAS-14. It is not a recommendation to drink.
What counts as a serving?+
The quantities are printed with each question exactly as they appear in the published instrument, including the 200 g vegetable serving and the tablespoon measure for olive oil, so your answers are scored against the same criteria the research used.
What do the bands mean?+
The 0-5, 6-9 and 10-14 grouping is a convention that appears across the later MEDAS literature; the original publication defines no categories. It tells you where a number sits on the scale, and nothing about you.
Does a high score mean my diet is healthy?+
No, and this page will not tell you that. The score measures similarity to one specific dietary pattern as defined by one questionnaire. What it means for you is a conversation for a qualified healthcare professional.
