Fiber content
Fiber per 1 large or thick slice (39 g): 3.9 g - that works out to 3.9 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 3.9 g in a 1 large or thick slice serving of bread, whole grain white, toasted is 16% of the first and 10% of the second. US food labels use a single Daily Value of 28 g instead, which puts this serving at 14%.
Calorie for calorie, the figure is 3.9 g of fiber per 100 kcal (this serving is 102 kcal). Among the 186 grains with USDA energy data here that is 8th, and 234th 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 bread, whole grain white, toasted alone would take 7 servings, and 38 g would take 10. Most days reach the target through several different sources.

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 Bread, Whole Grain White, Toasted 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.
