How this list is built
Every number comes from Nutrigate's USDA-derived generic food table, the same data behind the food nutrition scores. The daily reference for iron is 8.7 mg, an evidence-based adult amount; the app personalises it to you. Serving sizes are typical household portions, shown in grams so you can judge them.
