## Daily Value by population group

Source: FDA, § 101.9(c)(9). "Not applicable" means the nutrient is absent from that group's FDA table; "No DV" means it is listed with no established value.

| Population group | Daily Value | Low (5% of DV) | High (20% of DV) |
| --- | --- | --- | --- |
| Adults & children 4+ | 28 g | 1.4 g | 5.6 g |
| Children 1–3 years | 14 g | 0.7 g | 2.8 g |
| Pregnant & lactating | 28 g | 1.4 g | 5.6 g |
| Infants 0–12 months | Not applicable | n/a | n/a |

## Before 2016

For adults and children 4+, labels until 2020/2021 showed 25 g. Now 28 g. Increased.

Source: 21 CFR 101.9(c)(9), edition revised as of April 1, 2016. "Fiber | do | 25" (columns: Food component | Unit of measurement | DRV) "do" means the same unit as the row above (Total carbohydrate): grams (g).

The 2016 rule took effect on July 26, 2016 (81 FR 33742). Labels had to use the new values by January 1, 2020 for manufacturers with $10 million or more in annual food sales, and by January 1, 2021 for smaller ones (83 FR 19619). Values are for adults and children 4 or more years of age (21 CFR 101.9(c)(8)(i)).

## How is dietary fiber declared on a Nutrition Facts label?

Dietary fiber is a required line on the Nutrition Facts label, stated in grams per serving. (21 CFR 101.9(c)(6)(i)) Below 1 gram it does not have to be declared; a label may instead say “Contains less than 1 gram” or “less than 1 gram”, and below 0.5 gram it may say zero. (21 CFR 101.9(c)(6)(i)) When fiber is not required and so not declared, the label says “Not a significant source of dietary fiber” at the bottom of the nutrient table, except on the simplified format. (21 CFR 101.9(c)(6)(i)) Its %DV is highlighted, for example in bold type. (21 CFR 101.9(d)(1)(iv))

## How %DV is calculated

1. Divide the amount of dietary fiber in one serving by its Daily Value (28 g), and multiply by 100.
2. Round the result with this nutrient's %DV rounding table (§ 101.9(d)(7)(ii)), shown below.
3. 21 CFR 101.9(d)(7)(ii) permits either the actual amount in the serving or the amount declared on the label (itself rounded) as the basis for step 1.
4. FDA reads 5% DV or less as a little and 20% DV or more as a lot.

## Label rounding rules

- Regulation: 0 below 0.5 g · nearest 1 g above
