Question

In a typical healthy adult, what percentage of food consumed is absorbed in the GI tract?

Answer 1

In a typical healthy adult, about 90 percent of water ingested through food and beverages is absorbed in the small intestine.

Step-by-step explanation:

According to the reference materials provided, in a typical healthy adult, about 90 percent of water ingested through food and beverages is absorbed in the small intestine. The remaining water, along with other undigested food residues, is absorbed in the large intestine, resulting in the formation of feces. Of every 500 mL (17 ounces) of food residue that enters the cecum each day, about 150 mL (5 ounces) become feces.
