Study: Validation of the food compass score through 24 h recalls and measurement of erythrocyte fatty acids in a mediterranean population

The study found that people with higher Food Compass Scores ate more healthy foods like nuts and fish and less sugar and bread, and their blood showed more of the good fats linked to those foods. This means the score works well to tell apart healthy and unhealthy eating patterns.

Study: Clinical Application of the Food Compass Score: Positive Association to Mediterranean Diet Score, Health Star Rating System and an Early Eating Pattern in University Students

Study: Food Compass 2.0 is an improved nutrient profiling system to characterize healthfulness of foods and beverages
