Which Type of Fiber is Best For Colon Health – Soluble or Insoluble?

The use of fiber in a well-balanced diet is essential to the well-being of the colon. Waste from the body is disposed of through the colon. A healthy colon will function by getting rid of waste in a timely manner, not allowing it to cluster within itself. A fit colon requires bulk in order to eliminate regularly. That’s because your colon is a muscle, and just like any other muscle in the body it needs to be toned and strengthened in order to function properly.

Additionally, healthy colon cells thrive in the absence of harmful toxins, so removing those toxins is essential to good bowel function. Fiber helps with both of these things. Because fiber adds bulk to the diet, it gives the colon muscles something to push against. This in turn helps to move food through the intestines to encourage regular, healthy bowel movements.

Benefits of Fiber

Fiber-rich foods also work to absorb the harmful toxins that can build up in the digestive tract and lead to poor health. Not only that, but they help eliminate those toxins with each bowel movement. This prevents waste and contaminants from getting back into the bloodstream and settling in the body’s cells and tissues.

How Fiber Works on Colon

Now, different types of fiber help the colon muscles differently. There are two types of fiber: insoluble and soluble. Insoluble fiber has great water preservation properties, making it a natural laxative. Because the colon can absorb large amounts of water, this type of fiber aids in the formation of waste and in the speed in which it is processed through the body. Insoluble fiber attaches itself to the waste contents of the intestines and bulks up the stool. It helps the wastes pass through the bowels smoothly and without much stress.

Soluble fiber absorbs water and other substances inside the colon. It glides through the gastrointestinal tract and slows digestion. Soluble fiber forms almost a gel-like cluster as it is broken down in the colon by bacteria. That gel helps to aid in the elimination of wastes, as well as keeping the cells walls of the colon in good working order.


Proper and well-timed elimination of wastes from the colon is important for many reasons. Toxins within the colon are absorbed by the blood and carried to the liver to be detoxified. Too many toxins can overload the liver and cause many problems from fatigue to skin problems. In addition, a colon that doesn’t have enough fiber can lead to problems with constipation and irregularity, not to mention the more serious issue of increasing the potential for cancer-causing agents to remain in the body for long periods of time.

Therefore, both soluble and insoluble fibers work to keep the colon healthy. Soluble fiber keeps it clean on the outside and insoluble fiber cleanses it from the inside.
