Before you use the food ranking
A high value in the table does not automatically make a food best for everyone. Calories, allergies, sodium, added sugar, preparation, and portion size also matter.
Also, some foods are rich because they are dried, concentrated, fortified, or cooked. Compare similar serving sizes before making a meal decision.
