About dietary fiber
The dietary fiber Daily Value is based on a 2,000-calorie diet. Dietary fiber is a required line on the Nutrition Facts label, stated in grams per serving. 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. 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. Its %DV is highlighted, for example in bold type.
Questions about dietary fiber
What is the FDA Daily Value for dietary fiber?
The FDA Daily Value for dietary fiber is 28 g for adults and children 4 years and older. On a Nutrition Facts label, a serving's %DV for dietary fiber is its amount divided by 28 g, times 100.
How do I work out the %DV for dietary fiber?
Divide the amount in one serving by 28 g and multiply by 100, then round to the nearest whole percent. For example, 5.6 g ÷ 28 g × 100 = 20%.
How is dietary fiber rounded on a Nutrition Facts label?
A statement of the number of grams of total dietary fiber in a serving, indented and expressed to the nearest gram, except that if a serving contains less than 1 gram, declaration of dietary fiber is not required or, alternatively, the statement "Contains less than 1 gram" or "less than 1 gram" may be used, and if the serving contains less than 0.5 gram, the content may be expressed as zero.
Dietary Fiber rounding rules
Amount
Dietary Fiber is declared to the nearest 1g. Measuring finer than that changes nothing on the label.
| Amount range | Rounding rule |
|---|---|
| 0 to <0.5 | declare 0 |
| 0.5 to <1 | Contains less than 1 gram |
| ≥0.5 | nearest 1 g |
% Daily Value
| %DV range | Rounding rule |
|---|---|
| ≥0% DV | Nearest 1% |
Every %DV a label can show

The rules are FDA's; the inversion is ours. Ranges are inclusive at the low end and exclusive at the high end, because an exact half rounds up.
Does the dietary fiber Daily Value change for children or pregnancy?
Yes. It is 14 g for children 1 to 3 years and stays 28 g during pregnancy and lactation. There is no dietary fiber Daily Value for infants through 12 months.
How do I find out how much dietary fiber is in a food?
A Daily Value is a reference target, not a measurement of any particular food. To find the dietary fiber content of a specific ingredient or product, look it up in USDA FoodData Central, then use that amount here to see what a label would declare and what %DV it carries.
