Fiber is an important nutrient that supports digestion, heart health, weight control, and overall wellness. Found naturally in plant-based foods high in fiber, dietary fiber helps the body function properly by improving digestion and supporting healthy blood sugar and cholesterol levels. Despite its many benefits, many people still consume less fiber than recommended.
Adding foods high in fiber to your daily meals can make a significant difference in both short-term and long-term health.
What Is Dietary Fiber?
Dietary fiber is a type of carbohydrate that the body cannot fully digest. Unlike sugars and starches, fiber moves through the digestive tract mostly unchanged.
There are two primary types of fiber:
Soluble Fiber
Soluble fiber dissolves in water and forms a gel-like substance. It may help lower cholesterol and stabilize blood sugar levels.
Insoluble Fiber
Insoluble fiber adds bulk to stool and helps maintain regular bowel movements.
Both forms of fiber are essential for maintaining good digestive and metabolic health.
