Drewnowski's Index

Drewnowski's Index is a measure used to assess the nutrient density of foods relative to their energy content. It helps identify foods that provide essential nutrients—like vitamins and minerals—without too many calories. The index is represented by a ratio that compares the amount of desirable nutrients (like fiber, vitamins, and minerals) to the energy (calories) a food provides. Foods with a higher index score are considered healthier options because they deliver more nutrition per calorie, helping individuals make better dietary choices for health and wellness.
