Fiber is a type of carbohydrate found primarily in plant foods. Unlike sugars and starches, fiber isn't broken down and absorbed in the same way, making it particularly valuable as part of a balanced eating pattern.
Good sources of fiber include:
Vegetables
Whole fruits
Beans and lentils
Whole grains
Nuts and seeds
Fiber can help slow digestion, support blood sugar management, promote digestive health, and help you feel satisfied after meals.
If your current diet is relatively low in fiber, increasing it gradually and drinking enough water can make the transition more comfortable.
People with specific digestive or metabolic conditions may have different fiber needs. Consult a healthcare provider or registered dietitian if you're unsure how much fiber is appropriate for you or are planning significant dietary changes.
