How blueberries compare with other fruits

Blueberries rank 5 of 11 fruits in this library, by fiber in one serving.

Each bar is one serving: pear, 1 medium pear; apple, 1 medium apple, with skin; blueberries, 1 cup; banana, 1 medium banana; orange, 1 orange.

A cup, not a handful

The 3.6 grams is for a full cup, which weighs 148 grams. A small handful over cereal is closer to a quarter of that, about 0.9 grams.

Pair it with something heavier

A cup of blueberries in a cup of plain yogurt is still 3.6 grams, because yogurt has none. Add an ounce of almonds and it is 7.1.
