Key metrics

Nutrient density

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.
