One serving against a day's fiber
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 0.4 g in a 1 fl oz (no ice) serving of strawberry juice, 100% is 2% of the first and 1% of the second. US food labels use a single Daily Value of 28 g instead, which puts this serving at 1%.
Calorie for calorie, the figure is 5.2 g of fiber per 100 kcal (this serving is 7 kcal). Among the 121 fruits with USDA energy data here that is 19th, and 136th 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 strawberry juice, 100% alone would take 63 servings, and 38 g would take 95. Most days reach the target through several different sources.
