How can fiber contribute to digestive health?

Fiber significantly contributes to digestive health primarily by aiding the elimination of waste from the body. When consumed, fiber adds bulk to the stool, which promotes regular bowel movements. This increased bulk helps food move through the digestive tract more efficiently, reducing the likelihood of constipation and promoting overall digestive function.

Additionally, fiber can help maintain a healthy gut environment by supporting the growth of beneficial bacteria in the intestines. This is especially important for maintaining digestive health, as a balanced gut microbiome plays a role in digestion and nutrient absorption.

While other options may touch upon aspects of fiber's role in digestion, they do not encapsulate the primary and most established benefit of fiber in the context of digestive health as effectively as aiding the elimination of waste does.
