The large intestine is the primary site for the fermentation of undigested carbohydrates. This process is crucial for extracting energy and providing various health benefits. Both insoluble fiber and resistant starch undergo fermentation within this environment.

According to the Dietary Guidelines for Americans, more than 90% of women and 97% of men do not get enough fiber. This statistic is concerning because soluble fiber does, in fact, break down, but not in the way most people think, and this process is essential for gut health.

By the time digested material reaches the colon, the small intestine has already absorbed up to 90% of the water and most nutrients. However, the colon performs crucial, albeit different, absorptive functions that are vital for overall health.

About 9 to 10 liters of fluid pass through the intestines daily, though people typically drink 1–2 liters. This process is mainly managed by the intestines for proper hydration.

Over 90% of US adults do not consume the recommended daily amount of fiber, a crucial nutrient that feeds the gut microbiome through a process called fermentation in the large intestine. This unique metabolic activity, carried out by trillions of gut bacteria, transforms indigestible plant matter into powerful compounds essential for maintaining a healthy digestive system and influencing overall health.

The human gut contains an estimated 100 trillion microorganisms, collectively known as the gut microbiota. This dense and diverse microbial community is where short chain fatty acids (SCFAs) are primarily produced, with their synthesis dependent on the fermentation of undigested dietary compounds. These vital compounds act locally and systemically, influencing everything from gut health to immunity and metabolism.

The human body's digestive system processes an astonishing amount of fluid each day—around 9 to 10 liters, which includes both ingested liquids and internal digestive secretions. The answer to the question, "Is water extracted from digested food?" is a resounding yes, as the body reclaims this vast quantity of fluid through an intricate absorptive process within the intestines, ensuring hydration and regulating waste.

The human gastrointestinal tract is colonized by a vast and diverse community of microorganisms, with bacterial density increasing significantly towards the end of the digestive system. This dense microbial population, particularly in the large intestine, is responsible for producing a variety of essential vitamins, including vitamin K and several B vitamins. This symbiotic process is crucial for maintaining overall host health and supplementing dietary vitamin intake.

Approximately 90% of all water and most nutrients are absorbed by the small intestine during digestion. The undigested matter from the small intestine is passed on to the large intestine, where the final stages of waste processing occur before elimination.

Approximately 95% of short-chain fatty acids (SCFAs) produced in the gut are rapidly absorbed by the colon's epithelial cells, with only a small amount excreted in feces. This absorption is a cornerstone of gut health, enabling the body to utilize valuable metabolites from dietary fiber and undigested carbohydrates.
