Concentrated forms (not ranked)

Flours, powders, concentrates, sugars and fortified foods with niacin (B3), listed by value per 100 g but left out of the rankings above.

Which foods are ranked

• The 376 foods on CalorieExplorer with a reported niacin (B3) value. They are generic USDA FoodData Central rows (Foundation Foods and SR Legacy) with a plain name: no branded products, restaurant items, survey mixed dishes, baby foods or regional specialty rows.
• Only foods with more than 0 mg are ranked (370 foods); a food with no reported value is left out, never counted as 0.
• Flours, crude brans, powders and dehydrated foods, juice concentrates, mixes, sugars and fortified foods are not ranked: per 100 g they beat every food eaten as is. They are listed separately below.
• Ties share a rank: foods with the same value per 100 g get the same number, and the next number is skipped.
• Typical portion = USDA's own serving weight for that food (a medium fruit, 1 cup, 1 oz…), as on its food page. Per 200 kcal shows how much you get for the same calories; foods under 5 kcal per 100 g are not ranked that way (–).
• % DV = share of the FDA Daily Value for niacin (B3), 16 mg a day for adults and children 4 and older.
• FDA lets a label call a food “high in” a nutrient when one reference serving gives 20% of the Daily Value or more, and a “good source” at 10–19% (21 CFR 101.54). We apply it to the typical USDA portion, which is not always the label's reference amount.
