Tag: Absorption mechanism

The human digestive tract, a marvel of biological engineering, possesses a surface area equivalent to a tennis court, which is optimized to absorb the essential fuel our bodies need. This intricate process is fundamental to our health, but many wonder, how do nutrients reach the bloodstream?

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.
