According to extensive research, short-chain fatty acids (SCFAs) are produced by intestinal bacteria through the fermentation of dietary fibers. Propionate is one of the key SCFAs, a vital metabolite that plays a significant role in gut health and various systemic physiological processes.

According to the Mayo Clinic, dietary fiber is the part of plant foods the body can't digest or absorb. This fact is key to understanding the question: does soluble fiber go into the bloodstream, and if not, how does it provide its well-known health benefits?

As much as 90% of plant cell walls are made of cellulose, a complex carbohydrate and primary component of the insoluble fiber that is the most difficult plant material to digest. Humans lack the enzyme, cellulase, required to break down the strong β-glycosidic linkages in cellulose, causing it to pass through the digestive system largely intact. While indigestible, this tough, fibrous material is crucial for healthy bowel function.

According to the Linus Pauling Institute, the average American only consumes about 17 grams of dietary fiber per day, far below the recommended amount. A lesser-known but crucial aspect of fiber intake is fermentation, a process in the colon that holds significant benefits for human health. So, is fiber fermentation good? The answer is a resounding yes, as it is a foundational process for maintaining a healthy gut microbiome.

According to a 2019 study, psyllium husk significantly altered the gut microbiota of constipated patients, boosting the abundance of butyrate-producing bacteria. The question of whether does psyllium husk increase butyrate levels has been a subject of scientific inquiry due to the fiber's unique fermentation characteristics and its impact on gut health.

Did you know that while humans can easily digest starch, a key type of polysaccharide cannot be digested by humans? This indigestible compound, cellulose, is the primary component of plant cell walls and plays a vital role as dietary fiber in our digestive system.

While the small intestine is known for absorbing the vast majority of nutrients, the large intestine plays a crucial secondary role in nutrient absorption. This includes reclaiming essential water and electrolytes, as well as absorbing key vitamins synthesized by its resident bacterial population.

While vegetables are an undisputed cornerstone of a healthy diet, the common experiences of bloating and discomfort have left many wondering, "**Can our bodies digest vegetables?**". The truth is more complex than a simple yes or no, involving a remarkable collaboration between our body's own enzymes and the trillions of bacteria living within our gut.
