    The large quantities of bioactive compounds place blueberries high on the Aggregate Nutrient Density Index (ANDI). This index rates foods based on their vitamin and mineral content, phytochemical composition, and antioxidant capacity.

    Foods with the most nutrients per calorie have the highest rankings, and blueberries are placed among the top fruits and vegetables for nutrient density, with an  ANDI score of 132.  

    ANDI is one of several rating systems for food nutrition, but further research is needed to determine the role of specific foods in disease prevention.
