Corn

We're most familiar with the sunny, yellow version, but corn comes in a rainbow of colors—from pink to blue to black—each with its own special combination of antioxidant nutrients.

A single ear of corn, which is about a half cup of corn kernels, contains 2 grams of fiber. Popcorn is also a terrific—and low-calorie—fiber source, with about 3.5 grams of fiber per three-cup serving.
