Fiber is a key part of a balanced diet and plays an important role in digestion, heart health, blood sugar control, and weight management. Found naturally in plant-based foods high in fiber, fiber helps the body function properly by supporting the digestive system and promoting overall wellness. Unfortunately, many people do not consume enough fiber each day, often because modern diets rely heavily on processed foods.
Eating foods high in fiber can improve health naturally and support long-term well-being.
What Is Fiber?
Dietary fiber is a type of carbohydrate that the body cannot fully digest. Instead of being broken down and absorbed like other carbohydrates, fiber passes through the digestive system relatively intact.
There are two major forms of fiber:
Soluble Fiber
Soluble fiber dissolves in water and forms a gel-like substance in the digestive tract. It may help lower cholesterol and stabilize blood sugar levels.
Insoluble Fiber
Insoluble fiber adds bulk to stool and helps maintain regular bowel movements by supporting digestive movement.
Both types of fiber are important for maintaining good health.
