Fiber per 1 cup (50 g): 10.3 g - that works out to 5.7 g of fiber for each 100 kcal.

The Dietary Reference Intakes set an Adequate Intake for total fiber of 25 g a day for women aged 19 to 50 and 38 g for men of the same ages. Measured against those, the 10.3 g in a 1 cup serving of cereal, bran flakes, plain is 41% of the first and 27% of the second. US food labels use a single Daily Value of 28 g instead, which puts this serving at 37%.
Calorie for calorie, the figure is 5.7 g of fiber per 100 kcal (this serving is 181 kcal). Among the 186 grains with USDA energy data here that is 3rd, and 116th across all 957. The intakes above were derived from 14 g of fiber per 1,000 kcal, or 1.4 g per 100 kcal, so this food sits above the ratio a whole day of eating is meant to reach.
Getting all 25 g from cereal, bran flakes, plain alone would take 3 servings, and 38 g would take 4. Most days reach the target through several different sources.

Portions
| Portion | Grams | Fiber | kcal |
|---|---|---|---|
| 100 g | 100 | 20.5 g | 361 |
| 1 cup - this page's serving | 50 | 10.3 g | 181 |
| 1 prepackaged single serving | 30 | 6.2 g | 108 |
Gram weights come from the household measures on the USDA record; fiber and energy for each portion are its per-100 g values scaled to that weight.
You have the number. Adding Cereal, Bran Flakes, Plain to the tracker is free - as is every one of the 961 foods here - but the tracker only keeps the last 14 days in view. Premium keeps every week of your log and turns that history into trends: your average fiber per logged day, the days you hit your goal, and how many of the 30 weekly plant groups you have actually eaten. Custom foods and JSON/CSV export are included.
