Fiber is a type of carbohydrate found in plant foods—like fruits, vegetables, grains, legumes, nuts, and seeds—that your body can’t fully digest. And that’s actually a good thing.
Instead of being broken down and absorbed like sugar or starch, fiber moves through your digestive system, sweeping up waste, feeding your good gut bacteria, and helping your body stay balanced from the inside out.
How It’s Different from Other Carbs
Most carbohydrates are broken down into sugar (glucose) for energy.
Fiber isn’t.
Instead, it passes through the digestive tract, offering huge benefits for your gut, blood sugar, hormones, heart, and more.
