What are some good sources of fiber?

Good sources of fiber include fruits and vegetables, whole grains, legumes, nuts, and seeds; variety matters because fiber from different plant foods can nourish gut microbes. 1 2

• Choose whole grains over refined grains: Whole grains are a fiber source; refined-grain foods are distinct from whole grains. 3
• Beans and lentils: Legumes provide fiber; the cited discussion also identifies them as sources of plant-based protein. 1 4
• Eat a variety of these foods: Diverse fiber sources support gut-microbiome diversity. 2
