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 7.5 g in a 1 cup serving of blackberries, frozen is 30% of the first and 20% of the second. US food labels use a single Daily Value of 28 g instead, which puts this serving at 27%.
Calorie for calorie, the figure is 7.8 g of fiber per 100 kcal (this serving is 96 kcal). Among the 121 fruits with USDA energy data here that is 11th, and 47th 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 blackberries, frozen alone would take 4 servings, and 38 g would take 6. Most days reach the target through several different sources.

Portions
| Portion | Grams | Fiber | kcal |
|---|---|---|---|
| 100 g | 100 | 5 g | 64 |
| 1 cup - this page's serving | 150 | 7.5 g | 96 |
| 1 berry | 5 | 0.3 g | 3 |
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 Blackberries, frozen 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.
