Every figure here is per 100 g of the food, not per serving. That makes foods comparable to each other, but it is not how anyone eats: 100 g of a dried spice and 100 g of a leafy green are very different portions, so a high position in this list does not tell you what a meal contributes.
Nutrient values are per 100 g of the USDA reference entry named on this page and vary with variety, growing conditions, storage and preparation.
% DV compares the per-100 g amount with the FDA Daily Value of 16 mg for adults and children aged 4 and over. It is a labelling reference, not a personal target.
