On average, how long does food take to move through the digestive tract? Are there any foods that are prone to getting "stuck" and causing upset?

We normally add about 7 liters of water (from the blood stream) to what is ingested, so that the food becomes a thin watery soup in order to facilitate digestion; enzymes can only get to what is suspended, with a large surface area, in a thin watery solution. ...Read more

Nexium (esomeprazole) reduces acid so does it create a more hostile environment for norovirus in digestive tract? Do I have less chances of getting sick if on Nexium (esomeprazole)?

Nexium (esomeprazole) reduces acid so does it create a more hostile environment for norovirus in digestive tract? Do I have less chances of getting sick if on Nexium (esomeprazole)?

Unlikely, HCl acid: Secreted by stomach has no digestive affect, it makes it difficult for ingested micro-organisms to function or stay alive. The amount of HCl acid secreted can drive stomach liquid from pH=7 to pH=1, a million fold increase in proton concentration. Suppressing stomach acid secretion makes us potentially more vulnerable to harmful microorganisms. Yet most people tolerate Nexium (esomeprazole) 1, 000 fold? Acid. ...Read more
