The Study
Validation of the food compass score through 24 h recalls and measurement of erythrocyte fatty acids in a mediterranean population
This study looked at whether a new food score (FCS) matches up with what people actually eat and what’s in their blood. It found that people with higher scores tended to eat more healthy fats and veggies, and had more omega-3s in their blood. But it didn’t change anyone’s diet — so we can’t say the score makes people healthier, just that it matches what healthy eating looks like.

Where the score came from
Scientists made a new score (Food Compass) that rates how healthy your food is — like a report card for your meals.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — higher scores mean your diet is richer in heart-healthy fats and antioxidants, similar to the Mediterranean diet, which is known to protect against disease.
- 2People with higher Food Compass scores had 13.8% more EPA and 1.8% more DHA in their blood — both good omega-3 fats — and ate more veggies, nuts, and olive oil, less sugar and white bread.

The Food Compass Score assigns lower numbers to less healthy foods like snacks and desserts and higher numbers to healthier foods like legumes, nuts, and seeds, distinguishing between them more precisely than other food rating systems.
Among healthy adults following a Mediterranean diet, those with higher dietary quality scores based on the Food Compass have measurably higher levels of EPA, DHA, and the omega-3 index in their red blood cells.
Among healthy adults in Mediterranean regions, a higher Food Compass Score is linked to a lower proportion of daily calories coming from carbohydrates.
In healthy adults following a Mediterranean diet, the Food Compass Score and the Mediterranean Diet Score rise together, showing they measure similar aspects of healthy eating focused on olive oil, vegetables, legumes, and fish.
Adults in the Mediterranean region who eat dietary patterns scoring high on the Food Compass have higher levels of EPA, DHA, and the omega-3 index in their red blood cells.
In healthy adults following a Mediterranean diet, a higher Food Compass Score consistently corresponds to higher scores on the established Mediterranean diet adherence index.
