Common questions

How much iron do I need per day?

The FDA daily value is 18 mg for adults — 27 mg in pregnancy. The per-100-kcal column shows density: plant sources like spinach and legumes look very different per calorie than per gram.

Where do these numbers come from?

USDA FoodData Central (SR Legacy and Foundation Foods), synced per food with source entry IDs on each food page. One dataset, one per-100 g basis, per-100 kcal computed here.

Method

Values are USDA FoodData Central per-100 g figures (SR Legacy / Foundation), the same rows behind every food page on this site; per-100 kcal is computed as nutrient ÷ kcal × 100. DV = FDA daily value for adults (18 mg for this nutrient, 21 CFR 101.9).
