Key metrics
Nutrient density
Per 100 kcal, dark chocolate delivers about 4% of a Daily Value on average across 22 beneficial nutrients. The score is its percentile for that measure among the 177 foods in our database — higher means more nutrition per calorie. How this is calculated.
- More iron than 100% of foods · 100% of other
- More fiber than 98% of foods · 100% of other
- More potassium than 97% of foods · 100% of other
Density counts protein, fiber, and vitamins and minerals (not fat, sodium, or sugar), each capped so a single nutrient can’t dominate, with a calorie floor so very-low-calorie foods aren’t overstated. It measures nutrition per calorie within our database — a useful guide, not a complete verdict on how “healthy” a food is.
