What Are Foods That Contain Roughage?

Foods containing roughage, or fiber, include fruits, vegetables, cereals and grains, nuts and legumes and even some canned foods. Among fruits, raspberries offer the most fiber, with 8 grams of fiber in each 1 cup serving. Apples and pears come next; a medium-sized fruit of either variety, with the skin on, contains approximately 4 to 5 grams of fiber.
