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 2.2 g in a 1 cup serving of fruit smoothie, light is 9% of the first and 6% of the second. US food labels use a single Daily Value of 28 g instead, which puts this serving at 8%.
Calorie for calorie, the figure is 1.9 g of fiber per 100 kcal (this serving is 114 kcal). Among the 186 grains with USDA energy data here that is 52nd, and 484th 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 fruit smoothie, light alone would take 12 servings, and 38 g would take 18. Most days reach the target through several different sources.
