Over 90% of people in some Western countries don't consume enough fiber. This is partly because humans lack a specific enzyme that breaks down fiber, but our gut microbes more than make up for it.

Every time you chew a piece of starchy food, such as bread, the enzyme amylase in your saliva immediately begins breaking down the complex carbohydrates. This demonstrates a key biological function: specialized enzymes are required to break down large polysaccharide molecules into smaller, usable sugars.

Over 75% of people experience occasional gas and bloating after eating cruciferous vegetables like broccoli, cauliflower, and cabbage. This digestive discomfort is often caused by the body's inability to fully break down certain complex carbohydrates and fibers in these nutrient-dense foods. Fortunately, specific digestive enzymes can help mitigate these symptoms, allowing you to enjoy the health benefits of these vegetables without the negative side effects.

A compelling biological fact is that while both starch and cellulose are polysaccharides made of glucose, the human body can digest starch but not cellulose due to a critical enzymatic and structural difference in their molecular bonds. This fundamental distinction dictates what serves as a key energy source versus what functions as indigestible dietary fiber in our digestive system.

Research in 2022 showed that while some enzyme preparations derived from Aspergillus have prebiotic-like effects, cellulase itself is an enzyme, not a prebiotic fiber. This distinction is critical for understanding its role in the gut and its impact on digestive health.

The average American consumes over 15 grams of dietary fiber daily, a significant portion of which is cellulose from plants. But is cellulose broken down in the human body, or does it simply pass through? The answer reveals a fundamental difference in human digestive biology.

Interestingly, humans do not produce the enzyme cellulase naturally, unlike herbivores such as cows. So, how does cellulase help the human body? Supplemental cellulase aids in breaking down cellulose, the fibrous component of plant cell walls, which can lead to significant digestive health benefits.

As humans do not naturally produce cellulase, an enzyme needed to break down cellulose from plants, digesting high-fiber foods can be challenging for some. Cellulase supplements are designed to provide this crucial enzyme, helping the body process plant matter more efficiently.

Despite being the most abundant organic polymer on Earth, humans cannot obtain nutrients from cellulose. The reason for this lies in a fundamental difference between our biology and that of many herbivores: the human digestive system lacks the necessary enzymes to break down its complex molecular structure.

Cellulose is the most abundant organic polymer on Earth, making up the structural components of virtually all plant cell walls. Despite being a carbohydrate composed of glucose units, humans cannot use cellulose as a source of energy because our bodies lack the necessary enzyme for digestion.
